    This car belongs to BimmerBoost vendor @fastgti69 who of course is using his own VM (Ventura Motorsports) N54 single turbocharger kit on his 6-speed manual E90 335i. He recently got it out on the dyno with Terry of Burger Motorsports to do some fine tuning. The result is over 800 wheel horsepower and 834 horsepower and 720 lb-ft of torque at the wheels to be exact. The thing is, they are not done here. There is more in this car. The N54 horsepower record still stands at 861 rear wheel horsepower but as we have more N54's pushing deep into the 800's along with further tuning revisions for these high horsepower cars we should start seeing records fall. Further details below from @Terry@BMS: Hey guys, Spent some time on the dyno today with Payam@VM's car. Main purpose of testing was to evaluate the new JB4 single turbo O2 sensor calibration and JB4 port injection control. In doing that it appears we also upped the official bar a bit for single turbo N54 power. Notes: 1) This big turbo really sings at 35psi. It's starting to get to the point that we need to add 4bar and 5bar MAP sensor support to the JB4. It's on my radar. 2) Car has a major issue dropping timing in cyl4. We have no idea why. 3) The JB4 o2 sensor control is working very well. It's amazing how lean we were running previously without really giving it much thought. The second dyno file is a comparison to his testing a couple months ago. AFR was creeping up to the mid 13s. If you're running a single turbo and not using the latest JB4 o2 sensor control firmware, your AFR is much leaner than you think it is. 4) The JB4 port injection control is working perfectly as well. It's convenient being able to datalog and change it from the same JB4 interface and it's nice that it finally self corrects for low fuel pressure. Much more planned for this. 5) Given the AFRs are accurate now we're using *a lot* more fuel than we did previously. Maintaining low pressure on E80 (as read via JB4 flex fuel sensor) has become an issue again. Been funneling data to Fuel-IT who has some new stuff in the works. 6) I heart JB4 anti-lag.

    Congratulations to BimmerBoost member sA x sKy who put down some eye opening numbers with his DCT F82 BMW M4. He managed to crack the 700 wheel horsepower barrier with his BMS JB4 tuned car which is upgraded with the Pure Turbos Stage 2 S55 turbochargers. @sA x sKy has upgraded Dodson clutches which is the way to go for BMW DCT upgrades. Noting this is a DCT car is important as it is currently the highest horsepower DCT F80 M3 or F82 M4. The 708 wheel horsepower Pure Turbos Stage 2 upgraded F82 M4 we saw a few months back has a manual transmission. Great numbers here and further details from @sA x sKy below. We also look forward to seeing more timeslips from this car. So two different people told me to make a new thread for this.. so I hope you don't mind Sticky :D So my car was finally fixed today for a timing chain issue (second time..) and we wasted NO TIME whatsoever going to the dyno since street tuning was out of the question b/c of the weather outside. Literally we retimed the engine, put on the carbon fiber brace/strut brace on, turned on the car for 10 seconds.. and said fuck it let's go dyno. With the help of Jesse@PURE and Terry@BMS, I did 5 runs. 640whp, 658 whp, 660 who, 679 whp, and 704 whp! Had I had time for one more run I could have taken the dyno record but I'm content with this for now. We were building boost slowly up first but because the 5th run was the final run of the day, we said fuck it and went straight to an 85 meth additive for the 704! NO CODES. NO DTM. NO LIMP. The car ran amazing those 5 runs. 100% meth with 5 gallons of MS109 Thanks to Petrolwerks for building this awesome machine! And thank you Jesse@PURE, Jason@TPG, Terry@BMS, Mo@ACM, and T0ny32 for all the help along the way. Seriously, this project wouldn't have been possible had it not been for the combined efforts. Atco track rental is on Wednesday to hopefully break another record! I ran a 11.17@126 (maybe 127 I don't remember) with M/T ET Streets II. I have upgraded Driveshaft Shop axles this time so not worried about going full boost on this thing off the line. Objective is a 10.5@XXX. This is the highest whp F8X DCT in the world as of right now, and second highest whp overall. Can't thank Jesse@PURE and Terry@BMS enough for the personal touch for this car.

    Its been discussed before, but finally got around to looking at it after the failure. Bought a flood recovery motor from a wrecking yard complete for $1200, they told it was for a core only, could not be run. So of course it was immediately installed and made 700WHP..:) Needless to say it developed a tapping noise not long after that. The next day to be exact, I tried to mess with valve train, and realized it was the bottom end, and not the top end, and continued to drive the car as it ran great. After about a week the noise went away, good ole self machining. Fast forward to the next day, I am on the freeway just cruising along around 70, and all hell breaks loose. Never even bothered to put the car in the air, but finally got around to getting another used motor, so pulled this one, and found a lot of fun stuff. Basically a rod failed on the piston side, exploding the piston through the oil pan, and onto the freeway, this then caused the half broken rod to freewheel 360 degrees, and light sabre everything in its path, including cutting the water pump in half, vacuum pump in half, oil pump, block, you name it, if it was in the way, it was rendered in two..:) The pictures are pretty funny. I'm keeping some of these parts...:dance:

    Well we all knew it was coming here it is. The VTT Black Friday promotion. We do not need any gimmicks, fancy names, mismatched turbos, any of that. With VTT its a simple premise, you buy a turbo that does what its advertised to do, and has for years. Which is set records, on and off the track, and give you trouble free service. The ONLY N54 turbos on the market with 100% custom turbine wheels, designed, and manufactured specifically for us, dual turbine end piston rings, custom thrust parts, brand new CHRA's, the list goes on. We innovated every single N54 turbo upgrade you see on the market today. From 9 blade turbines, to custom thrusts, to 2" snouts, to silicone inlets, you name it, we did it first. People have asked how other brands have come to make the same power so quickly. The answer is simple when you provide the blue print for something, its not hard to copy it, and replicate the results. Imitation is the sincerest form of flattery they say. We could not agree more. With the marketing BS out of the way, we are offering a simple discount of 10% off everything on the site, if you order a set of Stage 2, or 2+ N54 turbos. We will throw a set of inlets in the box at no charge. The competitions "SALE" prices are the same as our normal prices, so our sale prices are well, you get it.

    Hey guys, i just want to start of with how horrible of an experience this has been. I chose VTT back in October 2014 because he wasn't so well known at the point and i figured that since he was putting out all these turbos that he would be great to work with. Little did i know that i would be going through two sets of turbos 13 months later....:facepalm Here goes from the beginning. October 2014 - FBO N54, 84k miles driving strong. OEM turbos give out. October 2014 - Turbos arrive on time and installed. Pull strong for almost a year straight and 11k miles. September 14 2015. One day, BOOM. Compressor wheel chipped and now is all bent up. HORRIBLE shaft play. Uninstall, send to Tony. Promised 2 week turn around time for Stage 2 rebuild OR option of Stage 2+ to compensate and was told 3 weeks. Well.... 3 weeks you say hmm? screw it, one week extra of down time for more power?! ill do it! September 18 2015 Turbos received. September 22,2015 Finally able to open turbo and confirm he received them. Opens them up and claims the turbos were deprived of oil.....but they worked for 11k miles and literally a year. My mechanic stated that he highly suggested a piston inside was installed incorrectly causing the compressor shaft to get funky and shear it self. This is where he says 3 weeks from this date is when i will get my Stage 2 + turbos. Remember that detail....Stage 2+ for 3 weeks.... September 24,2015 Email'd tony to confirm, Me:"We are still at a 3 week wait for the Stage 2+ upgrade right?" Tony: " Looking at the workload 3 weeks seems accurate. If anything changes i will let you know." SWEEET..... October 9, 2015 Emailed tony just to make sure we are still going on time. Tony : "We are getting these out to you next week. you have my word." October 15, 2015 Emailed again. he states "Im actually working on your turbo right now. These should be out by tomorrow".....the 16th right? nope.... October 16, 2015 - The day that they were promised to go out. Received email from tony. "I just wanted to make sure we were on the same page. i dont remember what we agreed upon. Did we agree stage 2 rebuild or stage 2+ upgrade? Let me know so i can get started, Just know that im low on stage 2+ housing and it will be a FEW MONTHS before i can get them to you. ." I told him i wanted stage 2+ still and you stated it would be 3 weeks not a FEW MONTHS.... October 19, 2015 Emailed received again. tony states " I understand what was said but i have a list of people waiting for their stage 2+ And it would be unfair for me to let you budge in line".... ok i under stand that but wouldnt that have been nice to know that 3 weeks ago? October 22,2015 I finally caved in and said screw this. i need my car back and if its so much easier just to get my regular ordered stage 2's then lets go. November 2, 2015 FINALLY received a email with shipping confirmation.....but we are already 7 weeks past the promise date... told me stage 2's would be 2 weeks.... nope that took 9 weeks. Told me stage 2+ would be 3 weeks...nope now that would be a few months. November 22,2015 300 miles later, Bank 1 turbo is now leaking oil. Contacted Tony stating how tired i am of this, i want a full refund of this since this is going now be my THIRD turbo from him...... contacts me back and here is his reply word for word. I can attached screen shots if you dont believe me. " Kien, Honestly while i am bummed you you have another issue. Im going to say its something going on with your car. What i have no idea. We are not RB, we do not have machining issues, billet wheel problems, none of the above , any issues we had are WELL in the past. We build turbos that perform, and flat out last, period. I honestly cannot even recall the last set of stage 2's we had a report of smoking in the past year, except yours. So if your car is smoking again, its not the turbos, something else is going on. I would never blame something as silly as inlets, etc etc. I cannot say what is going on, but i can assure you its not the turbos, at this point, unless there was an install error etc, that caused oil starvation, or another issue such as something getting sucked into the turbo. With that said we cannot offer you full refund, we are not doing a recall, you an the exception, not the rule. If this was common place, then yes we would have to step up, and offer refunds, but it is not. I can offer you a 50% refund, minus Paypal fees, core, and shipping or another set. There are many questions that need to be answered, how often was the oil changed through its life, etc etc. My own personal car, had a chronic smoking problem, guess what when i swapped the motor out with the same turbos on it, the smoke went away. Same turbos, different motors, no smoke. Go figure. As far as the rattle, come on man. It has been gone over and over and over and over. THERE IS NO 100% RATTLE FIX. We put brand new robust parts on there, they eliminate 90% of peoples rattle, but if you have your tune set up so when gates are not closed the flapper sits just off the house, it WILL rattle period. All that needs to be done is adjust the WG position with the tune, and it goes way. Let me know what you want to do out of the teo options above. Tony" Alright..... well im not settling for 50% refund when these turbos are not performing as they should. i have contacted my credit card company and will be filing a dispute. Current car symptoms: - NO white smoke on cold start. - White bluish smoke when warmed up driving and coming to a stop. Idles and smoke comes out, when accelerating smoke comes out. - heavy burnt oil smell -turbo seal? took plastic trays off under car. Oil is seeping and dripping from turbo. No VCG leak, no PCV problems, No OFHG leaks.... Looked at bank 1 turbo, turned on car to idle and watched oil slowly seep from the bracket that holds the housing together.......not turbos you say tony? you either have a bad turbo seal here or a bad CHRA..... Oil is leaking from the bracket here in the yellow circle. You can see here, after wiping it down a little, the yellow circles show where the oil is coming out of. I have already confirmed that it is not coming out of the feed/return oil line. Most recent Log. Log before VTT stage 2 died. Please be cautious guys.... im now stuck with a broken car again and fighting to get a refund because i have already paid twice $1200 to uninstall and a THIRD time... If anyone can help me out some how please do.

    Lswhat started a thread Max Torque Reduction by RPM in N54
    as the title states, im trying to inquire more on the max torque reduction by rpm. who here has played around with this at all? Ive tried a few different things on this and I feel like this setting greatly has an impact on 60' My assumption so far is that this setting has to do with the torque converter lock up? Someone please chime in if I am drastically wrong here, but from changing it around that's what it appears to be for me. I have done a few tests with this, and I want to know if anyone else has tried changing it and what theyre results were.

    So... Ive been sitting here thinking, and I wanted to share one of the quickest and easiest ways to improve your 60' when drag racing. Its a pretty simple concept, and Definitely a DIY. hah. So here it is, One of the biggest drag racing mistakes people make right off the bat, is as simple as where they "Stage" their car. Staging, as in the two top yellow bulbs is the easiest and simplest way to improve your 60' and even as much as improving your top end mph. Staging is a series of 3 beams, pre stage, stage and guard beam. the guard beam is essentially usless to us as that is just to ensure your car isn't too low, or that you are trying to falsly trigger the top end beam. So the first beam, the prestage beam, when staging your car you want to take your time. typically I turn my top bulb on and let my fellow opponent do the same thing (Courtesy Staging) once both top bulbs on, my staging routine is fairly simple, and I do the same thing EVERYTIME. once both our cars are in the first beam I get on the converter on my car and SLOWLY bump the breaks so that I move less then an inch each bump, and I continue to do so @ 2000 rpms until the 2nd bulb (stage) is on, which is typically 7" at most tracks. and then get on my converter even harder, typically 2500-2800. But heres the catch... All of you people that blindly roll into the 2nd (stage) bulb have no idea where you are actually staging. In a perfect world you want to BARELY turn that 2nd bulb on therefore giving you 7" more of usable track, people may ask, "Why do I want to make the track longer?" and your answer is as simple as this... Your timer DOES not start until BOTH beams are fully connected again, meaning that your E.T. does not start ticking until you have moved approximately 7" So by this "shallow stage" method you will actually see higher mph, and lower 60' Your reaction time as well is recorded as soon as you technically recreate the beam, from the time the light turned green. in a perfect world you want to leave as soon as you see the last yellow light come on. I have been bracket racing for a number of years, and ill take my Camaro for example, that car does not react worth a damn. So typically I do my stage routine, but then give it 3 extra "bumps" decreasing the 7" to idealistically 4" which in return will improve my reaction time, but those 3 bumps cause my 60' to go from a 1.70 (when I shallow stage) to a 1.78 (deeper staging) and the overall E.T. will typically drop from a 11.85 @ 115mph (shallow stage) to a 11.98-12.00 @ 113.8 with a 1.78 (deeper stage) 60' You can even go as far as turning the top bulb completely off, which just means that the original "prestage" beam is back intact and your front tire is only breaking the stage beam. And I know a lot of you out there are thinking, this guy is full of shit, I dare you to try it next time you are at the track, try BARELY turning on the 2nd bulb one pass, and then the following pass deep stage and turn the top bulb completely off, I would bet you lose close to 2 tenths (.2) off of your total e.t. and at least 1-2 mph, provided you did everything the same as the pass before. I hope this helps someone!

    I will start this by saying, I am very new to the BMW scene, I bought this car in early September, but have been drag racing for 10+ years. I read a lot, and barely ever post. Ive built a couple 9 second lsx cars and I decided to build something "different" so I decided to start my first "import" venture. So after a long 2 weeks of wrenching on my car, I finally got it all together Wednesday night and only had thurs night to retune and I decided to trailer the car 4 hours down to Atco dragway in new jersey, I am from Mass. I was very happy with my results! ill post the time slips below, working on getting the video from my buddy. Previous to Yesterday my best was an 11.84 @ 118 so I put myself in some debt to try to get the quickest awd 335, over the past 2 weeks I had almost the entire car apart, I will put a (*) next to what I changed since I started with a simple turbo rebuild, which ended up with an over torque and a snapped turbine, so I decided to reach out to Tony @ Vargas, and man he hooked me up! within 5-7 days of contacting him I had in my possession 2 brand new OEM CHRA's and a set of his inlets. All I can say is that the customer support I received from him was absolutely unbelievable. Everytime I sent him an email I received a response within 5-10 MINUTES. like clockwork, and I can be a HUGE PITA as I ask a lot of questions, and I basically try to do everything myself. I do believe this is the quickest 335xi? and it was also done one stock turbos! Mods List: VTT Inlets* VTT Oem CHRA's* JB4 BMS 1gal Meth (100%) BMS DCI n20 map VRSF dp VRSF 7" FMIC* Fuel it stage 1 lpfp running e55 MHD Custom base Flash by Johnny B Tuning Stock exhaust with gutted rear cats TDR Prorace 1.2 17" wheels with SNOW tires* Yesterday I made quite a few passes trying to dial the car in as its never been on a dyno, and she got faster every pass. 11.518@122, 11.43@123.99, 11.33@124.7, 11.31@124.99, 11.277@125.04, then dropped the stock exhaust and went an 11.30@125.56 spinning all of 2nd gear. The main problem I was running into, was the track prep went from good to horrible around 2pm and my last 2 passes it spun, the 2nd to last pass it spun so hard it auto shifted 2nd gear before even moving, and then the last pass it hooked 1st had a 1.67 60' and then annhialated the tires in 2nd gear, I had to pedal it, short shift 3rd and still pulled off a 11.30 A 125.56 I KNOW the car has more in it, as I really only had 4-5 runs in before I put it on the trailer and went to New Jersey. If I had to guess the weight was somewhere around 3700-3750 +/- 50, I didn't have time to drain fuel and ran it with 3/4 of a tank all day. Overall I was very happy, and have to thank Tony @vargasturbo for all of his help, and to Johnny B (JBoyorak) for his killer tune! I would expect to see this car in the 10's very soon. On this very setup, I already know where I can lose another 150lbs and how I can get the 60' to low 1.6 high 1.5x

    Pictures do not do it justice. Audi's Press Release on the second generation R8 was well done with great photos but you just have to see the car in person to really understand how it is distinguishes itself from the previous generation R8 model. The new grille, headlights, rear lights, air intakes, etc., all combine to make the second generation R8 much more flattering. The proportions somehow seem more muscular and less awkward. The second gen car is just basically a reskinned Lamborghini Huracan with both cars sharing the same basic chassis, dual clutch transmission, and 5.2 liter naturally aspirated V10 engine. The R8 V10 Plus model you are looking at essentially matches the Lamborghini Huracan with 610 horsepower and 413 lb-ft of torque. The R8 is no longer neutered to the degree it was with the previous generation versus its Lamborghini sibling. What we want to know is when the R8 will be getting an entry level model soon to replace the defunct 4.2 FSI V8 model but boosted from the factory as reports hint at. For now, Audi is mum on the topic and the V10 engine remains the only option in the range. #LAAS2015

    Hi, I was wondering if anyone had any tips on getting the front dp in. It seems to be a bit of a puzzle. I know they fit as i've done this once before out of luck and a lot of time and this time around and i'm on the lot of time still but no luck yet. Does anyone have any tips on orientation, ways you pull the dp, etc to get it to fit? Rear one in but clamp loose? Do you angle it in from the corner below and try to get it up? Do you pull it a certain way and then move the rear one around? Keep o2 in the front rear do or leave it out? Can you swap it in after dp is up? I'm going to try again soon but can't seem to replicate the first time yet. Should it be this hard to get the front one in on the xi? I read that they've never had a revision to it & it has fit once so I know it's possible. Thanks

    Hello, I am working on an open source project and I figured it would be best to collaborate with as many people as possible. This project is for my N55 car, but I bet this will apply to other BMWs too (probably any BMW after 2008). The goal: Make my own progressive methanol injection controller. Purpose: Current meth controllers use different approaches for determining engine load. Some use straight boost (AEM), while others use a much more advanced approach of interpreting sensor values (Aquamist). However, all of these approaches are somewhat "inexact" in my opinion when you consider the goal, which is to inject a certain percentage of the total fuel amount at any given time. The Aquamist is probably the best (and likely more than precise enough for its purpose), but all of these kits still have the issue of installation complexity; I want to avoid tapping a bunch of wires under the hood. The purpose of this project is to create a meth controller that is both very precise and very simple to install. This is also partly driven by my curiosity. Approach: In short, I will obtain realtime engine fuel mass delivery rate data from the OBD interface and use this to drive an Aquamist fast acting valve (FAV). The 2011 E92 335i uses CANbus (500kbps) for OBD-II communications, and the car supports the UDS protocol. The fuel mass delivery rate will be requested using a standard UDS "get ID" (0x22) request. Then, once I have the fuel mass rate, I will convert it in to cc/min (taking in to account the specific gravity of gasoline). The result will be the TOTAL cc/min flow rate for the engine (which can sort of be converted to horsepower if you make some BSFC assumptions). I've created lookup tables (12 entries deep) for various fuel volume flow rates, which will allow for the mapping of the desired meth flow percentage (see MethService.h). The desired meth flow percentage (percentage of total fuel flow rate) will then be mapped to the required PWM duty cycle that the meth injector must be presented with to achieve said flow rate. There's more to it, but this is the general idea. I may update this post later with more details. Until then, see the code for details... Possible Issues: Conflicts with Cobb datalogger. Since there will essentially be two OBD devices on the port, this could cause conflicts. However, since this car uses CAN, it shouldn't be a problem. That's part of the beauty of CANbus. I do make use of the HW filters in the MCP2515 to try to reduce processing overhead for messages I don't care about, but those filters don't inspect deep enough into the message to select only fuel mass responses, so if the Cobb is using the same CAN ID, there could be issues. It all depends on how the Cobb obtains its data. Failure Modes. Special care must be taken to make sure that all possible failure modes result in NO INJECTION of meth. The Code: This project is open source and licenced under the LGPL. The LGPL was chosen because I don't want someone to simply take this code and incorporate it into their closed sorce project without giving proper recognition and support to the community. The LGPL essentially forces any changes to this code to be published openly and forces any closed source programs that make use of this code to provide a means to obtain the LGPL'd portions of the code and re-link to them. In other words, your closed source program CAN use my code, but it should be dynamically linked and you need to provide a copy of my code along with any changes you made to it. That being said, since this is the LGPL and not the GPL, feel free to incorporate this code in to your closed source project, but with restrictions. See the LGPL for more details. The Hardware: I am using a ruggedized version of the Arduino UNO for this project. It's basically the same as the regular Arduino but with a better power supply which can handle 3V-30V and is rated for extended temperatures. I am using the MCP2515 CAN controller with the corresponding transciever, both of which are part of the Jaycon CAN shield for Arduino. I am using the Arduino (OEM) 4 relay board to drive the meth pump and failsafe outputs. I am using the Arduino tinkerkit MOSFET board to drive the Aquamist FAV. This includes a flyback diode, which is nice. Progress I am able to query the fuel mass delivery rate from the ECU and can successfully interpret the values. This was done using some quick test code that I threw together just to prove the concept. Since then, I've been developing this "offline", so I don't know if the current code in the reposity works or not. The full code is basically complete, but I haven't tested it yet. I plan to drive around and log the PWM duty cycle and make sure things are sensible. Then, I will install the actual meth kit and tape the nozzle to the windshield to make sure things work as expected. Please review my code and let me know what you think. Feel free to contribute! Sorry if this post is "incomplete". The project can be found at:

    So I've been chasing a few things around and I got a lot of my tuning issues figured out with making sure actual load doesnt exceed requested load, etc. Sadly though, I think I found the limit of my HPFP with 100% E85. In the log below everything is fine except once the boost gets high up there the HPFP drops down to 500 psi :(. Once it gets that low the ECU seems to pull timing across the board even though everything is great (AFR is fine, STFT's look fine, everything looks great). What's sad is that at higher RPM the pump can keep up just fine! Its in the 2k-3k RPM range that it appears it just cant keep up... which makes me a sad panda. But then again, this is at 20psi in very cold weather (yay 43 deg F IAT's!) Am I right in thinking the reason the HPFP cant keep up at lower RPM is because its chain driven from the crank and thus at that RPM it just cant move enough fuel? If so I guess it might be time for port injection, throttle body injection, or a shotgun fuel pump :(.

    The W205 C-Class platform transition from sedan to coupe is more elegant than the preceding W204 generation. While the W204 coupe produced some odd proportions the W205 generation C205 coupe looks like it was designed to be a coupe from the onset. The proportions in person are beautiful and clearly take on some S-Class coupe inspired elements namely with the rear end design. It is muscular, angular, and modern. Quite simply, it is beautiful and more so than its sedan sibling. This is the 'Edition 1' C63 AMG S Coupe which is named for the launch model. This is for those who have to be the first to have it. So what does Edition 1 offer? Mainly unique trim elements as you can see with the yellow decals, wheel finish, and interior stitching. It is attention grabbing but has a 'boy racer' element to it. The yellow highlights are not exactly what one would call elegant. The interior details are beautiful though. The Edition 1 is only available in the matte grey finish you see and the AMG Aerodynamics Package is included. You can also get the Edition 1 in standard 469 horsepower C63 trim or C63 S 503 horsepower trim. Whatever your thoughts may be on the yellow accents there is no denying the C205 C63 is a gorgeous coupe. #LAAS2015

    Gave the 60-130 another shot tonight at a private track with our 2015 M5. Changes since run including swapping from CM7 to CM10 nozzles, going up to straight meth, and limiting boost in 3rd gear to 24psi to give the stock tires a chance of getting traction. I might add limiting boost in lower gears is a JB4 only feature for this platform. Anyway was able to improve our time to 6.5s and on a 1% slope this time to boot. The extra fuel definitely helped speed it up. As a reminder mods are JB4, BCM, BMS intake+chargepipes, Dodson clutch packs, BMS meth (dual CM10), straight meth, ~95 octane fuel. Full factory exhaust including all factory emissions equipment. Temps in the mid 60s. You'll note this JB4 log also has AFR for both banks shown. I recently added that to the firmware with some other changes and will post that shortly!

    Nice results here for Eurocharged modifications on the S55 3.0 liter twin turbo direct injected engine platform from the BMW F80 M3 and F82 M4. The Stage 1 tune on the stock exhaust puts down 452 wheel horsepower and 459 lb-ft of torque at the wheels on pump gas. Add in catless downpipes and power climbs to 477 at the wheels. The tune and downpipes provide a boost of just under 50 horsepower at the wheels over the catless downpipes alone. These are all pump gas numbers. With higher octane or meth injection of course things can be pushed further. Pricing is typical Eurocharged which means the best value for the quality in the business. $1400 for downpipes and a tune for the F80 M3 and F82 M4 is a steal.

    Great numbers here from a GIAC tuned B8.5 Audi S4 3.0 TFSI supercharged V6 equipped with the DSG dual clutch transmission. At ATCO in New Jersey (one of the nation's quickest tracks) the owner managed several mid 11 passes culminating with a new overall B8 S4 record of 11.462 @ 120.03 The fastest trap speed was 120.34 on a 11.494 pass. Here is the mod list for the car: AWE Tuning B8.5 Stage 2 Performance Pulley Kit AWE Tuning Resonated Downpipes and Touring Edition Exhaust G.I.A.C. Stage 2 V2 Engine Software - GIAC 104 file on MS109 fuel G.I.A.C. DSG Performance Software Upgraded intake, heat exchanger and reservoir Lightweight front/rear rotors and wheels It is important to note there is weight reduction as well with the passenger seat pulled as well as the spare and jack. On the stock 3.0 TFSI blower owners can continue to try to one-up themselves but it comes down to weight reduction and the best conditions to try to eek out new records. What the platform really needs to start seeing to move to the next level is larger superchargers.

    exxxtacy started a thread 29E1,29E0,29F1 codes in N54
    The other day I decided to try some E85 for the first time since I added my inline 255 fuel pump piggyback. Added about 14 gallons with some 93. Ratio was about 1/4 tank 93 and 1/2 E85. Put it into MAP 7 and tried a 3rd gear pull i felt the car hiccup and throw me into map 4. Tried it again but in map 5 and it did the same thing. Car drove normally after that till i got home. Later that day I started the car with a cold start and it had a longer crank but finally fired up, idle bounced a bit but finally settled down to normal and continued to drive normally but i ended up getting a 29E1 and 29E0 code which I cleared right away and it would come back about 5 minutes of driving. Let the car sit overnight and today i wanted to give it another shot to see if i could get it to run a log to see whats the issue. This time it had a even longer crank and it took two attempts to fire up but this time it would stall out instead of staying steady. I ended up getting the half engine light and when I scanned it with my Jb4 app I got a 29F1 along with the other two codes. It clearly isn't keeping pressure and making it stall out. Did a little research and maybe its the HPFP? any clue where to start? Im sure i ran a bit of an aggressive mixture but with the fuel setup i thought for sure it would handle it.

    Quite the sight to behold. Take in the beauty that is the beast known as the Mercedes-AMG GT3. Now although this race car is based on the AMG GT it uses the powerplant from the previous generation SLS GT3 platform which is a 6.2 liter naturally aspirated V8 known as the M159. This vehicle is designed for gentlemen racers which means a customer can purchase it and go racing in various GT3 classes around the globe. Not exactly a cheap way to go racing but this is for big boys competing with the world's best. It will be interesting to see if the Mercedes-AMG GT3 will evolve to house a direct injected turbo motor for racing bringing a closer tie to the actual AMG GT street car. The GT3 drivetrain remains very similar to the previous generation SLS GT3 down to the sequential transaxle gearbox. The vehicle itself is stunning and the security guard Mercedes-AMG had on hand agreed with me on that point. He stated they had a hard time sourcing even one of these for the show and wanted to make sure nobody messed with it. A logical precaution for a machine of this caliber. Simply a stunning vehicle. #LAAS2015

    Another year and another LA Auto Show is in the books. There were some exciting debuts. Alfa Romeo made a splash with their new Giulia. Mercedes-AMG of course had the new C63 AMG coupe which is gorgeous. Not enough can be said about Ford and their GT350R Mustang and the GT. BMW of course had their M4 GTS, Dodge their Viper ACR, and Acura their NSX. The emphasis on enthusiast cars may be diminishing but they are still alive and well with some of the best iterations yet. These are exciting times for performance enthusiasts. That is not to say everything is all sunshine and rainbows as the presence of Lotus basically evaporated and manufacturers keep pushing electric drivetrains which is where we are headed. The enthusiast market probably has 20 years left at best before autonomous electrics that drive you take over. Enjoy it while it lasts. Here's a recap of our coverage: LAAS 2015 - BMW wants $134,200 for the 2016 F82 M4 GTS LAAS 2015 - Volkswagen is delusional and acts like everything is fine by deflecting attention to electric powertrains LAAS 2015 - The 'new' 2017 R231 Mercedes SL is the old Mercedes SL LAAS 2015 - Alfa Romeo brings a few Giulias and a few gorgeous women to Los Angeles LAAS 2015 - The world's ugliest F82 BMW M4 created by LT Motorwerks, LB Performance, and Crzy Engineering LAAS 2015 - We can't get enough of the new Ford GT LAAS 2015 - The C205 C63 AMG coupe is gorgeous - Mercedes-AMG brings their Edition 1 AMG C63 S Coupe LAAS 2015 - Aston Martin's bespoke DB10 created for James Bond LAAS 2015 - The second generation Audi R8 is simply stunning LAAS 2015 - Mercedes-AMG brings the AMG GT GT3 race car and it is badass LAAS 2015 - The Lotus US presence is on life support - Exige V6 Cup photos LAAS 2015 - Go racing with Porsche's Cayman GT4 Clubsport for $165k - PDK Cayman GT4 #LAAS2015

    We are glad Ford brought their GT and GT race car to the 2015 Los Angeles International Auto Show. For one, it is gorgeous and any auto enthusiast would be forgiven for staring at it for hours on end. Secondly, it is incredibly rare and an auto show is likely the only place one will get to see a GT. Ford did not just bring the production version but also the motorsport version designed to compete at Le Mans. Ford is very serious about their return to racing in 2016 to coincide with the 50th anniversary of the original GT40's victory over Ferrari. They also have been spending a lot of time testing the vehicle and showing that the loss of a V8 does not mean the car will lose any performance. On the contrary, the new GT is poised to offer world class performance. Soak in the beauty that is the Ford GT. #LAAS2015
