    Did a little messing around on the dyno last night on the crappiest of crap California 91 ACN gasoline, no meth. With a really conservative tune, we ended up with 585WHP / 500WTQ. Yes this is a new N54 91 WR, no we do not like putting it in all caps, red letters, and 75 font size, as honestly who is going to run this. We did this testing to satisfy the people who will inevitably ask about 91. For the tuning we literally ran 1 degree of timing at redline (yes that's ONE degree), sometimes less if it corrected. We could have pushed harder, but after every pull I found myself checking for lumpy idle, etc. This really isn't a good feeling, and the idea of breaking an expensive built motor to push any harder on 91 was decided against (there was more in there). As usual Dzenno made small changes, until we got where we wanted. This was running about 24-25 psi, and as I stated before, no timing. The 91 has been drained out of the car, and sacrificed to the power washer gods. We will continue on with some E85 testing...:paddle: I think you guys know the specs on the car but here they are: ABR built motor VTT Stage 3 VTX2867 Turbo kit VTT Shotgun Double Barrel PTF Twin Disc clutch ACN 91, no meth Tuning by Pro Tuning Freaks

    So I figured I would share my experience with the community. Was out making a couple of pulls @ 25/26psi on my PTE 6466 twin scroll setup when cylinder 1 decided to give up on me. Not surprised a stock engine let go at mid to upper 600's, but I am impressed how long it hung in there. Put up a hell of a fight! Pics at the very bottom of my spare engine that apparently is now gonna get built. Log is from earlier in the evening: Also happened to have my GoPro watching the cluster:

    I'm going to put something together as this is our 5 year anniversary and I just want to say thank you to all of you. The people who have helped, those that have not helped, whatever. I want to show this community is the best ups and downs or not. I can't guarantee I can do this all myself but I also can't count on others to get it done. If any one of you wonder why I prefer working alone it is for reasons like this. So, please, just list what you would like in an app. I'm considering making it so that it connects directly to our new (and coming shotly) downloads section so you can just select a map from the app and download it just like that. I'd love to give back (as apparently the original BB app, new servers, and new features aren't enough) so just tell me what you want to do and Ill let you know if it's feasible. Let's be productive and positive. So, thinking caps on people! :stripper:

    Doing a bit of research on turbo sizing, I know there are several factors that influence choices: Peak power goals @ xxxx RPM Fuel available etc... But lets face it, there are poor sized choices, such as a tiny AR that would choke the exhaust or a giant AR that would require 10k RPM and nitrous to hit peak numbers. To say that every turbo option is somehow the "best" for a specific outcome desired I think is misleading. I have to imagine that turbo A is better at accomplishing your goals than turbo B, and both are worse than turbo C (all else being equal). This isn't magic, its science, right? With our BSFC, VE, liters, VANOs, DI and other known factors, there should be a pretty obvious compressor and exhaust housing that offers a very meaty power band, assuming its tuned correctly with the correct fueling that works better than an under-sized or over-sized option, or even worse, with an under or oversized option poorly tuned.

    So now that we see all the gains to be had with inlets. Slicksilver hitting 500whp i wonder what we can expect with just a compressor upgrade like the VVT stage 1. i mean i really enjoy tracking my car so i would be happy with a 500-525 whp daily driver. it really doesn't even seem like you need stage 2 anymore to break 500. and these can be had fairly cheap. right now fbo with jb4 and bb e85 back end i hit 410whp/440tq. i couldn't even imagine another 20-25% more power. just looking to statr a discussion and get some ideas. thanks

    This thread might get intense. So which one do you choose? Honestly, I'm starting to think the Viper is the way to go. I love the Z06. There is no 'wrong' car here. They're both incredible. But the Viper is just... raw. Something about it. There's something that makes you feel like they just won't build like this any longer. It's a tough one.

    Hello everyone. im Tamirlan from Moscow i bought bmw m6 in 2008, and started racing on different racing events, you could have seen my races on youtube on Moscow unlime 500+ i d like to tell you about my current project wich i started in the end of 2013 with Gintani. the reason why i chose Gintani is because of a great quality hardware and fine repuation. My previous set up was ess supercharger vt-2 730 hp + NOS kit ASR, overall 850 hp. on race event Moscow unlim 500+ it showed 27.5 sec on mile with 318 km\h. Which was not enough for me so i decided to modify engine to encrease hp/ at first i contacted with ESS because of previous succesful set up. but guys from ESS refused, because they aimed to e90/92. i started searching a company for building new low compration engine set up, with bigger supercharger and methanol injection. my main goal was to reach 1000+ whp. a friend of mine, Sergey who had been contacting with Alex earlier introduced Gintani to me. First time i contacted with Alex in august 2013, At first we wanted to reach 1000+ whp on s/c kit with engine modification. but Alex offered me a very interesting and unique project V10 5.5 TWIN TURBO with DCT gearbox,based on TT kit for m3 e92/90 wich they were finishing at the time. we discussed some terms and conditions of the project and reached gentelman agreement based on trust. In the end of november of 2013 i sent my engine from Moscow to the Gintani, and DCT i bought already in the US. for turbochargers Gintani chose two garret 35, engeneered and build custom exhaust manifold and every single peace was newly created. engine mods include custom camshafts, sleaweed block, corilla rods, custom forged pistons, headers porting and etc. displacement encreased to 5500cc with low compration ratio. evere single detail needed to be engeneered and design from start, and nothing could be used from big s/c kit so we missed our deadline. the guys from Gintani claim that we are on the finishing line, i hope guys will finish in a month and in 30 th of May i will show the fastest bmw m6 to the world on racing event Moscow unlime 500+ on 1 mile range. As Alex says the engine will produce 1200-1300+ WHP + DCT enhanced on dodson parts. it should be very fast set up with new world record potencial. im waiting for it for almost 1.5 year, i ve already missed 1 season. im hopimg that Alex and Guys from Gintani will meet the expectation. unfortunatly due to know how's and corporate secrets i can not post all the pics of the process and parts. My car is my passion, i bought new m performance steering wheel with rev indication from and a set of new carbon ceramic brakes from new m6 f13, os gicken with 50/50 differential block. new kw variant 3 suspencion. with all this hardware modification i couldnt let her look stock, the apperance of car should match its power so i chose full widebody original lumma clr kit with color from new m series - san marino blue. stock multimedia system changed to NBT, functionaly the car havent lost at all. for such amount of power i bought r21 355/25 looks crazy as hell... for to day everything is ready and installed, exept engine and gearbox..... can't wait to get things together and race it. many thanks to Alex and guys from Gintani, looking forward to see you in moscow. ill post here updates, engine mounting, dyno, first start etc.... also follow me on instagram BMW_dr_Tamirlan

    Hey guys, Met up with a local enthusiast Ash today to tune his new VT2 turbos and inlets. He's also running 100% E85 using a full Fuel-IT system & port injection. He has our canned E85 back end flash. The turbos and fuel kit performed flawlessly with only minor tuning changes needed to dial in boost and the port injection. We decided 600whp was a good stopping point which was around 25psi. I have no doubt there is another 30-40whp in there when he wants it.

    Had a chance to meet up with Payam today to tune his new PTE 6466 G2 twin scroll turbocharger. He's running our port injection and a full fuel-it kit (regulator & return line). 100% E85. Per usual I have a limited amount of time so I'll just share the highlights. 1) The 6466 G2 in a twin scroll works really well. Great boost potential and very good HP per PSI. 2) We found Payam's car wanted a lot less timing than I'm used to giving E85 cars. Around 7.5 degrees up top. 3) I tried a few VANOS curves and found the basic Cobb curves worked better than what we have in our ST back end flash files. Better spool and more power. Sigh. I think I'll just change those all back. 4) He ran in to timing drops around 30psi that we couldn't fix by lowering advance further so decided to call it a day for now. Hopefully it runs well at NFZ this weekend!

    Hi all, So vac is going to build me a complete engine. Forged bottom end with their stage 3 head and custom spec cams. Im deciding now to whether go lower compression or up the compression ratio and go full insane? Also the cam profile is not decided yet. I know nobody has ever put cams on these engines, but all opinions are welcome. 264 with 10.2mm lift is too much? The turbos are vtt stage 2+. Thanks

    Congrats to Steve, Evolve and Undercover Performance for taking the number 2 spot (oh so close to number 1) in the all time fastest (world record) 1/4 mile supercharged M3 category!!:music-rockout: @undercover @Imran@Evolve Here is the thread that was started about the car and how he ran a 10.5 @ 132.66 : Doing what I can to help ALL of us DCT guys. I never had a DJ Dyno with the E625 kit, so I scheduled one for this past Monday (3/30) at PSI Proformance in Lansdale PA. Filled up on 93 octane and off I went. While I was there, I called Atco Raceway to see when they had a private rental available. Turns out they were drying the track for one that day Once I was off the dyno, I headed straight to the track (roughly 70 miles), stopped just long enough to get my number and got to work. FINALLY DCT DRAGSTRIP TESTING TIME!! So, I was using Hoosiers on Apex ARC8's, and have the GTS DCT S/W. Unbeknownst to me at the time, the GTS s/w does NOT let you set 5500 RPM for Launch Control. I wish I knew this beforehand. Either way, it worked at 3500 rpm and Im not sure it would have helped considering the track prep was not great. It was good, but not great. First 2 passes I clicked off: Both of those bumped me into the #2 spot for E9x M3's. #1 spot for unmodified S/C kits (overall #1 is running 10+PSI and a Giant Ice/Water tank mounted in the trunk) But it got even better. With a few more hot-laps to try and run down the pump gas I had in the tank, I couldnt wait to add the Racegas I was itching use.. I ran about 10 more times with almost no deviation even as the DA was rising, 10.5-10.6@129-132mph in -470DA to -33ft DA Around 2:30 I finally got the gas down to below a 1/4 tank and added the 100 octane and tune to match. I had the guys respray the starting line for us because we were going all in now.. I did one "easy" pass to keep tires warm and get the racegas in the system and let the adaptations set in. Came right back around to stage again and let her rip! Like a bat out of hell the car launched! Sadly, shortly after I shifted to 2nd I heard the SNAP and all the lights came on and the car stopped accelerating. Long story short, we got the car back to Undercover Performance ( who does all my work) and we found the problem. May i present to you, the FIRST "known" broken E9x Driveshaft We could be wrong, but Ive never heard of one breaking. As much as it sucks to break, at least its an easy fix. It also lets us know that the clutches are doing their job transferring every bit of power Im throwing at them. Bad news for me, but good news for the community. To summarize: * Dodson Clutches are working well * Expect to upgrade the Driveshaft if DragRacing And most importantly *My car is a ROCKET ( Best ET 10.544 / Best MPH 133.33 )

    Hey guys, we've just finished our new batch of Solid Diff Bushings: - Made from Thermoplastic Vulcanizate, not cheap polyurethane - Offers the hardness of plastic for a more solid mount - Offers the elasticity of rubber for unsurpassed durability - Self-Lubricating and resistant to oil and the elements - Will not crack or deform like polyurethane or rubber These replace all 3 of the Differential Carrier Bushings (2 x Front, 1 x Rear), effectively locking the Differential Carrier in place and removing any sloppiness associated with worn bushings. The result is a much more stable rear-end, increasing traction and reducing wheel-hop. Please Note: Due to the Differential Carrier having a more solid mount to the subframe, there may be a slight increase in NVH MSRP: $149.95 + Shipping Introductory Special (first 10 sets sold): $100 inc Shipping within North America/Europe/Australia Please let me know if you have any questions :)

    I am selling my basically brand new (1700 miles) motiv 750 Single turbo kit. The kit comes with everything you need for install. Why am I selling: Only reason I am selling is because I want a top mount and that is the ONLY reason, This is arguably one of the best kits for the N54 period. NOTE: with ER FMIC I had to trim less than 1/4" off the CP since ER has a extra long end tank, this will NOT hurt anything on your install if you use different FMIC and if you like I will get you new CP but is honestly not needed. I just want to make sure all cards are on table. Price: $6950.00 plus shipping (buyer covers shipping and 3% Paypal fees or gifts payment). No over seas shipping, no checks no wire transfers, just paypal or cash. This price I am pretty firm on, Turbo has never went above 23psi and only on several pulls. Included is custom filter with metal top, custom MAC selonoid bracket & custom cut heat-shield and 12-AN fitting on filter for OCC. You can use rubber hose with clamp or -12AN fitting with this setup. If you choose not to run a OCC you can get cap for $5.00. Kit will take 2-4 weeks to remove since I will be waiting on other kit to limit down time so there are 2 options. 1. Put down 50% and pay other 50% once kit is off and ready to ship 2. Pay in full, still will have the waiting time (some prefer to pay up front so giving this option). Motiv 750 kit before install, looks the same except slight coloration on manifold (normal).

    I wanted to share my recent outrageous interaction with MFactory. I wanted to get an lsd for my 135 dct. About 10 weeks ago they were offering specials for chinese new year and thought i would put my order in and get one since it was $300 off the normal price. So on February 22nd i paypal my $2000 to them. They contacted told me it might be a few weeks to get cores and i was fine with that. Then it became a month...nothing no pms from them at all ever...i pm them and response was this: Re: deal on dct lsd?Hey there, I can confirm we have 4 cores coming in just now, and should be arriving in a few days time. once we receive them, we can get the machine work done on them, and then starting building the units with the LSD. I'll update you on the progress next week when I get more news. Thanks and sorry for the delay! Originally Posted by VegasJD So its been 2 weeks since I sent you payment for the LSD, Whats the progress and when might it ship to me? Thanks, James Originally Posted by MFactory We've had some difficulty sourcing good low mileage cores, but have a couple of them coming in soon. Will keep you updated. Thanks and sorry for the delay. Originally Posted by VegasJD ok so its almost been a month...any update? so I wait another week pm them and get this: Re: deal on dct lsd?1 of the DCT cores arrived today, and the others should be arriving next Mon/Tues. It will take around a week for the machine shop to finish their work on the ring gears, then we can start rebuilding the cores which only takes us 1 day. So i give them another 10 days before i send a pm and i get this back im thinking well it should be shipping any day right???:confused: Re: deal on dct lsd?Hey Jim, just checked with the machine shop there, and it is due back within the next few days. Thanks and sorry for the delay. SO i wait another 15 days...in that time NO response or update from them at all. Any response from the initial came in response to MY Pm's nothing from them EVER!! Next few days is not another 2 WEEKS!!!:angry-banghead: SO its been 2 months since i paypaled $2000 so the following day i sent a dispute to paypal saying its been 2 months since i paid for goods and i have nothing. WOW you should have seen how quick they responded to paypal...record time lol 15 minutes...here is what i sent paypal and here is the response i got from Mfactory... I paid 2 months ago, i have to constantly bother the seller as to an update when product coming in and when it might be shipped. Before this last time it was 15 days since we spoke and at that time he said it would be a few days now its been over 2 weeks. I am tired of waiting they keep pushing it out and telling me to wait im tired of waiting. I shouldnt have to bother them to get an update when its done. From Seller - MFactory Competition Products 4/23/2015 00:42 PDT Instead of submitting a dispute, why not just contact/PM me? If you wanted a refund, I would have happily gave you one. You did not have to submit a dispute, thus putting our account balance in PayPal into the negative, thus locking our account and not allowing us to receive website transactions (yup, locked paypal account = can't use = can't refund you). Your core is being built just now (there were other people before you, just so you know), but I will just sell it to next in line. You're going to have to wait for the refund now though until I get a direct paypal payment (as I said, you made it so that we can't process orders through our website anymore. Thank you so much for that btw). If only you had waited a few more days (or contacted me)... So instead of contacting me and shipping out my lsd if it was "ready" like they said it was they cancelled my order. They are so happy to sell it to the next person in line...WOW that floors me. This is the angry pm i get from him complaining he had to fund paypal with his personal credit card as no funds were in the account...kinda weird that you have to fund a business with a personal cc instead of something business...sounds really shady to me!:think: Re: deal on dct lsd?You could have at least given me a chance to reply to you first before submitting a dispute. Not only did you put our PayPal account into negative, you also locked our account preventing us from processing more website orders/payments. I had to manually fund my PayPal account with my creditcard just to refund you and unlock our PayPal account. At $1500 + $500 refundable core fee, that was already heavily discounted. No where will you ever see that kind of deal ever again. If only you had given me time to reply to your PM, none of this would have happened as your core is currently being rebuilt and would have been ready to ship out today to you. As it stands, I've refunded your payment and have cancelled your order. If you do wish to reorder in future, price is $2199.95 + $500 core fee. We no longer have them on special as we have a very large list of pre-orders for these, and you would have to line up again (currently 8 people on the list). So they refund my money well im waiting on it... instead of shipping out my lsd which was supposedly "ready"...how is that a good way to do business...so i guess the deal i was getting was never really going to happen EVER!!...to me it seems i was made to wait till i got fed up and they wouldnt have to give me a deal on it. I am confused why they tell me what it costs to reorder one from them now...like i want to give them my money again to hold it for how many months they feel like it LOL NOT!!! I will give my money to a business that treats its customers right and does the right thing. this is the next pm trying to some how explain why they cancelled the order instead of shipping it out.. Re: deal on dct lsd? As mentioned, your dispute put our account into negative, which effectively locked our account, preventing us from doing further business transactions on our website. As we are a global business, and the timezone that you are in, that would mean we would have lost 5 figures in sales by the time you woke up and responded. Obviously we couldn't ship your core out to you before we received payment (which we didn't have, as PayPal removed it from our account). They had my payment for 2 months...how do they not have payment? WHAT i dont have what i paid for is the problem. The funny thing is they responded in 15 minutes to just cancel it no trying to work things out...a really GREAT way to do business. I was sent this the day after i complained to paypal as well. Re: deal on dct lsd?As mentioned, because of the timezone, you would not have (and did not) replied within an acceptable timeframe. Our business does not just cover the US, but is global. We cannot afford to have our PayPal account locked at any time, as we process orders via our website 24/7. And yes, I have a business creditcard, not that that has to do with anything. Again, I apologise for the inconvenience. I sincerely understand your frustration, but please understand why I had to cancel your order in the manner that I did. I love how he assumed i would not have responded in time...i wasnt given any time to respond it was cancelled out right lol. I understand why my order was cancelled...waiting 2 months wasnt long enough to wait...CANCELLING a discounted order is easier than filling it...WHY keep the customer happy? the goal is to make money and provide no customer service what so ever....right? So i assumed this company was in California as it says on their profile but im guessing its in china somewhere. If anyone else has had similar experiences please chime in...I wouldnt do business with a company like this ever!....i run 2 businesses and would never treat a customer like that! I wanted to share what happened to me so it doesnt happen to anyone else on the forum.

    I removed a leaky 12mm wide seal from my engine (11117584398) and am replacing it with the newer version, 8mm wide seal (11117587168). I notice the old seal has two grooves in it that are supposed to line up with the seam in the two piece block, then be filled with sealant and the new seal does not have these grooves. I also notice there is reference to a bunch of special tools to install the seal to the correct depth, but a simple measurement is not specified. So, two questions: Should I put a thin coating of sealant on the ID of the block where the two halves meet before I press in the new seal? What should the installed depth of the seal be relative to the face of the block around the seal?

    After a few emails with Sticky it would seem people are becoming increasingly offended by some of the negative vendor interactions by us, and many other vendors on this forum. We have decided to implement a new policy for ourselves, and our threads. It is outlined below. 1. Any vendor is allowed to post, and comment in our threads, doesn't matter who you are. 2. If at any time a vendor participating in one of our threads starts posting negative comments (back handed or blatant), derailing the thread, arguing with people in the thread, or generally side tracking the thread away from what it is intended for, they will be immediately removed from it. At the moment, this means we have to request for sticky to remove the offending person, as the ability to do it for vendors is not yet complete 3. We will keep our interactions with other vendors to a minimum, and will not post anything negative in another vendors thread it does not matter who you are. If us, or our products are directly referred to in a negative way, or false / misinformation is posted, and we feel wee need to address it. This will be done by started our own thread to address it. Not destroying the vendors thread with an argument. 4. At no time will blatant attacks, business, personal or otherwise be tolerated by anyone, non vendors included. We pay money to advertise here, and will not attacked in a place of business. This is social exercise for most, for us it is business, and will be treated as such. Again if we feel someone is being offensive, we will have them removed from the thread.

    This is not a new story but the only way to combat ignorance is with knowledge and data. Fortunately, there are members in the BimmerBoost community who provide quality data such as what you are about to see below and thanks to them we can differentiate between marketing and reality. The marketing is that the F82 M4 as well as the F80 M3 weigh 3306 pounds. What BMW left out was this weight comes from a European spec F82/F80 (they have different crash test standard affecting whether seats with side impact airbags are used) that is a 6-speed manual without any fluids whatsoever. In other words, it's a bunch of BS. Almost exactly one year to the day BimmerBoost posted an indepently weighed figure for an F80 6-speed manual M3 and it came in at 3562 pounds: This year thanks to member @DD GT3 RD (who also weighed his 991 GTS while he has was it) we have an independent weight figure for an F82 M4 DCT and it is 3661 pounds: Does the DCT add weight? Yes. It is not almost 100 pounds though but the difference between the lighter 6-speed F80 M3 and the DCT F82 M4 can be attributed to the transmission as well as fuel. The rule of thumb for fuel is about 6 pounds per gallon of gas. So how do the F80 M3 and F82 M4 compare to a DCT E92 M3? The previous generation car comes in as lighter than either of them at 3549 pounds. Yes, turbochargers, intercoolers, and plumbing add weight so BMW's hype was nothing more than hype. The aluminum-silicon S65 V8 block in the E92 M3 is very light and compact and this also leads to the previous generation car having better weight distribution. Do not believe everything you read. Especially if it's marketing from BMW.

    Ive been working on a project for the N54 community for a couple months but had not announced it since I wanted to be sure the concept was feasible. I have done enough now to know the concept is good so ready to share my R&D progress with the community. Description It is a TD04L-20T with true 20T native compressor housing. The 20T mistubishi profile compressor wheel is a forged billet wheel with extended tip technology from BorgWarner. The Turbo consist of a TD04 bearing housing modified to connect to stock oil lines, coolant lines and stock turbine housing. The turbine housing has been modified to accept the TD04L turbine and flange up to the TD04 bearing housing. The kit will include upgraded inlet pipe system and also charge pipe system optimized for the high flowing native 20T compressor housing which is over twice the size/flow of stock compressor housing. This will make sure the turbos are flowing to their maximum potential along with the upgraded plumbing for the turbo included. This turbo can push up to 35psi of boost and not sure what the actual WHP will be on the N54, but with proper fueling and meth cooling should be in the 750whp range theoretically at those boost levels near redline according to estimated compressor map and turbo HP calcs, only testing will prove if this is possible and I intend to test the prototypes to these levels with proper port injection and stage 3 LPFP. Schedule Current schedule is to finish development of the prototype set by the end of April/early May and install on my car and test and tune/dyno by the end of May. If all goes well I plan to get 10 beta test units out in June. If that goes well, start selling the kits to you all in July or August. I have completed my test fit on an N54 motor and finalized the designs for the wastegate actuator mounting and modifications and charge pipe (turbo to IC) design as well as making sure everything is going to fit on the engine. Everything went perfect on the fitup of the turbo to the engine so thats when I decided it was time to start sharing R&D progress with the N54 community. Pricing Dont have my final production pricing yet price point will be $3050 for both turbos, $450 for the basic inlet kit and $500 for the charge pipes from turbo to intercooler. If you already own my inlet pipe system, obviously no need to buy that. Only thing needed to adapt my inlet pipe system to the new turbos is two new elbows and everything else works Testing On my prototype system I plan to do dyno test and tune and push them to the maximum as I will have all the supporting fuel mods needed. I will be doing full logging of course. In addition, I will be doing custom turbo logging never before seen on the N54. Not only will I be logging EGT and backpressure (done before) to check health of the turbine but also I will log pressure and temperature at the turbo inlet and also at the turbo outlet which will tell me exactly what pressure ratios the turbo is working at and also at what efficiency. This compressor logging has never been done to my knowledge on the N54 but is the only real way to understand the compressor health during turbo operation. Quality The turbos are purchased from a large turbo supplier. I bought the CHRA from them to my specs which were basically TD04 bearing housing with 04L turbine and 20T billet 6x6 compressor wheel with extended tip technology from BorgWarner (for more boost). I also ordered the CHRA with upgraded thrust bearing, actually the highest upgrade possible, steel thrust bearing mitsubishi uses in the rally turbo cars where turbos REALLY get beat on and need bullet proof bearings. The compressor housing is the native 20T housing (over 2x more flow area) for TD04 and the entire CHRA is assembled and balanced by the manufacturer on a VSR machine they have in house and individual report provided for confirmation. I get the turbine housing machined at a CNC machine shop locally that deals with very high tolerance precision drilling tool parts and I assemble the CHRA to the turbine housing and wastegates "in my garage" and bench test wastegates on the turbos to ensure proper setting. Pics Now some pics to show you some progress :) Current Status update so quick update. We are doing a new manufacturing process for these hybrid turbos that has never been done before...well here is a sneak peak. The turbo manufacturer has designed a custom TD04 bearing housing that will flange up to the stock turbine manifold and bolt up to stock coolant and oil lines and will be investment cast to OEM (mitsubishi) specifications by a factory that also does casting for the OEM. To my knowledge this has never before been done on hybrid turbos for the N54. This will provide a true TD04 CHRA and will increase quality and reduce cost and be a MUCH cleaner solution in my opinion. This coupled with getting the right fittings designed and machined for the VSR machine is the reason I dont have my prototype turbos installed already but the delay is well worth it for the custom cast TD04 center section. I have partnered with the turbo manufacturer and he has made significant investments in the tooling required to manufacture the custom cast TD04 bearing housings but it will pay dividends in the long run in many respects. Also I am finalizing the charge pipes from turbos to intercooler and expect to complete those in a couple weeks and will have the turbo wastegate rod extensions complete also in a couple weeks as well as the wastegate mounting plate. Currently I expect to get the turbos delivered in early May and then in May I will be installing and working out the bugs and hopefully dyno tuning to max power by the end of May or early June. below is a sneak peak pic of the solid model design for the custom TD04 bearing housing design

    rader1 started a thread Fried MSD80 DME options in N54
    Ok, so my MSD80 fried a couple weeks ago and I've done the MOSFETs and unfortunately that didn't fix the problem and i'm out of other options at this point. Has anyone had any success using a used DME and coding it to another VIN? I can source a new DME for $1300 but with used DMEs going for fractions of that price I would atleast like to give it a shot.

    CAR decided to drag race the Audi RS7 and the BMW F13 M6. Now, the M6 is the lighter car. However, the advantage is in the RS7's court. It has an automatic transmission and all wheel drive so launching it as simple as putting your foot on the brake pedal, other foot on the gas, and then letting go of the brakes. Anyone can do it. The M6 takes a bit more skill and CAR does not seem to have it. Obviously a drag race is all about the launch. The torque these two twin turbo V8's put out is tremendous and the M6 will have traction issues. To get a good launch and actually make this a race the M6 needs drag rubber or at the very least the tire pressure lowered a bit and its tires warmed up to help. Obviously that is not always possible on the street and this result is what most people will see from a stoplight. The RS7 pulling away with no drama as the M6 fights for traction. Unfortunately, CAR provides no data on the trap speed or elapsed times for either car. Jump to to the 1:30 mark in the video to watch the obvious outcome.
