    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:

    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!

    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 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 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 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" is that a good way to do i guess the deal i was getting was never really going to happen EVER!! 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 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 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.

    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.

    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.

    The Porsche 991 Turbo S is a fast car. A recent test has the stock 991 Turbo S going 10.6 @ 130 in the 1/4 mile and we consistently see low 10's from bolt on tuned examples. That is not bad at all. The 918 Spyder though is simply on a whole different level of fast. The 918 Spyder is not turbocharged but its electric drivetrain provides a major torque boost. 431 lb-ft to be exact just from the electric motors. Combined with the naturally aspirated 4.6 liter V8 it makes 829 lb-ft of torque. Power is at 887 horsepower with the gas and electric motors combined. The 918 Spyder is considerably more powerful than the 560 horsepower 911 Turbo S. It is also roughly 250 pounds heavier but this difference is negligible at speed. It shows with how the 918 Spyder instantly pulls away. This is what a 145+ trap car with instant torque looks like going against a ~129 mile per hour car (PS guys, don't show your faces and the speedometer on public US roads as it can come back to bite you):

    For starters , i live in Europe (belgium) I own a E91 (yes a wagon :naughty:). Currently I am running following mods : Bms Dci , forge intercooler with OEM cooplers, Active autowerke downpipes, mechunik air scoops and an ecu tune from a local tuner. Atm it is making 400 ish hp (din) and 560 Nm at the engine. Recently my wastegates start ratteling so jt is time to decide to replace them . Since Oem turbos are nearly as expensive as hybrids i am prone going the hybride route ( RB , TTE500 , Hexon) My local tuner says he can't tune for max performance on the rb turbo due some torque restriction in the DME? Wich would trigger limp mode? The only way to bypass this would be a cobb accesport or jb4 with backend flash? Will the jb4 stack with my Ecu tune? .. or do i need to revert the ecu tune back to OEM at the Bmw dealer? I am not planning on running meth, just pumpgas 93 (oct 98 in europe) Really confused with all the options. Also a chargepipe with forge diverter valves , and stronger clutch are on the to do list) Thx :)

    Fishayyy started a thread E90,E91,E92,E93: Rear passenger side wheel squeaking. in 3 Series and M3
    The last month I developed an irritating squeaking noise that comes from the rear passenger side of my car at low speeds. Initially, I thought it was the brake pads, but I've also read it can be caused by a sensor. Has any one else had this issue and fixed it? I'm also considering removing the dust shield, not sure if that will help.

    I wrote this almost a year and a half ago on the other forum. Figured i'd dust it off and bring it to light. This is exactly why you do not want to inject meth in the CP on high HP cars. This is also the exact reason i went port injection a while back. If anyone knows how a OCC works by using velocity and change of direction will understand why CP injection is bad practice This is not my work besides N54 calculations at the end. Quote: you want to run the smallest possible without going over a certain air speed. 304 MPH or 0.4 mach is the point at which airflow meets increased resistance (drag) and flow losses are experienced. Depending on which turbo your running and what hp your looking for will determine piping size. to small is a restriction and to larger is laggy. generally for the average setup 2.25-2.5" is what works here is info i found on mach speeds of certain size piping relevant to cfm flow 2" piping 1.57 x 2 = 3.14 sq in 300 cfm = 156 mph = 0.20 mach 400 cfm = 208 mph = 0.27 mach 500 cfm = 261 mph = 0.34 mach 585 cfm max = 304 mph = 0.40 mach 2.25" piping 3.9740625 sq in = 1.98703125 x 2 300 cfm = 123 mph = 0.16 mach 400 cfm = 164 mph = 0.21 mach 500 cfm = 205 mph = 0.26 mach 600 cfm = 247 mph = 0.32 mach 700 cfm = 288 mph = 0.37 mach 740 cfm max = 304 mph = 0.40 mach 2.5" piping 4.90625 sq in = 2.453125 x 2 300 cfm = 100 mph = 0.13 mach 400 cfm = 133 mph = 0.17 mach 500 cfm = 166 mph = 0.21 mach 600 cfm = 200 mph = 0.26 mach 700 cfm = 233 mph = 0.30 mach 800 cfm = 266 mph = 0.34 mach 900 cfm = 300 mph = 0.39 mach 913 cfm max = 304 mph = 0.40 mach 2.75" piping 5.9365625 sq in = 2.96828125 x 2 300 cfm = 82 mph = 0.10 mach 400 cfm = 110 mph = 0.14 mach 500 cfm = 137 mph = 0.17 mach 600 cfm = 165 mph = 0.21 mach 700 cfm = 192 mph = 0.25 mach 800 cfm = 220 mph = 0.28 mach 900 cfm = 248 mph = 0.32 mach 1000 cfm = 275 mph = 0.36 mach 1100 cfm max = 303 mph = 0.40 mach 3.0" piping 7.065 sq in = 3.5325 x 2 300 cfm = 69 mph = 0.09 mach 400 cfm = 92 mph = 0.12 mach 500 cfm = 115 mph = 0.15 mach 600 cfm = 138 mph = 0.18 mach 700 cfm = 162 mph = 0.21 mach 800 cfm = 185 mph = 0.24 mach 900 cfm = 208 mph = 0.27 mach 1000 cfm = 231 mph = 0.30 mach 1100 cfm = 254 cfm = 0.33 mach 1200 cfm = 277 mph = 0.36 mach 1300 cfm max= 301 mph = 0.39 mach What you need to do is find you airflow rate based on : Basics you will use these numbers later on PRESSURE RATIO = (14.7 + your desired PSI) / 14.7 = PR convert CFM to LB per MIN = CFM x 0.070318 = LB/MIN (@ sea level and 112 degrees*) LITERS TO CUBIC INCHES DISPLACEMENT = # of L's x 61 CFM = Cubic Feet per Minute now using my car as an example: 3.0L (183. cid), 7300 Redline, desired boost is 25 PSI CALCULATING AIRFLOW RATE AT REDLINE and MAX PSI cid = Cubic Inches Disp. VE = Volumetric efficiency in percent .5 = (given) 4-stroke engine fills cylinder only on one-half the revolutions 1728 = converts cubic inches to cubic feet Airflow in CFM = (cid x rpm x .5 x VE%) / 1728 = CFM no boost CFM x PR = CFM under boost so for my N54: PR = (14.7 + 25 ) / 14.7 = 2.7 Airflow = (183 x 7300 x.5 x .85) / 1728 = 328.56 CFM (no boost) 328.56 x 2.7 = 887.12 CFM under 25 PSI A cubic feet of air (length+width+height) weighs different at diff. Altitudes and different temperatures. to simplify it well just assume we are at sea level and the air temp is 112 *. the conversion number is 0.070318. so for CFM TO LB/MIN = CFM x 0.070318 = LB/MIN 887.12 x 0.070318 = 62.38 LB/MIN (most speculate the precision 6466 is a 90lb turbo, this shows how much room is actually left in it. About 30% more left in its efficiency range) so here we have: BASIC ENGINE FLOW RATE = 328.56 CFM ENGINE FLOWRATE with 25 PSI = 887.12 CFM (62.38 LB/MIN) PRESSURE RATIO (PR) = 2.7 In conclusion you can see that a 2.5” duct is enough to support 913 CFM where as my car is pushing 887. I know its border line but here are some things to consider. Pros: 1. Drivability is more preferred 2. If I really wanted to squeeze the lemon I’m sure another .5PSI would overcome 3. The increased speed (about 50mph) has more of a “ram air” effect theoretically filling the cyl better. Cons: 1 meth distribution has less time . (direct port would probably be more preferred)

    Impressive numbers here out of BMW's N20 2.0 liter turbocharged and direct injected four-cylinder. The baseline number is strong as the N20 is severely underrated. 245 horsepower at the wheels and 268 lb-ft of torque at the wheels on a Dynojet dynamometer. So what is the result with basic bolt ons including an intake, downpipe, and ECU flash by Jailbreak tuning? How does 290 horsepower and 345 lb-ft of torque at the wheels on 91 octane pump gas grab you? That is a gain of 77 lb-ft of torque at the wheels with basic modifications. The N20 is really moving along now that the ECU can be flashed. Hopefully we see some flash tuned turbo upgraded setups. As far as how strong the motor is we do not know as nobody has really pushed it. That said, this is more power and torque than a stock E46 M3 to put things in perspective. This 228i is going to be a hell of a track car.

    I would just like to hear feedback from our users if you are satisfied with the quality of updates and articles. Is the frequency of updates fine with you? Do you feel the performance scene is adequately covered? Do you want something different? I personally feel that I have a good pulse on the entirety of the aftermarket and automotive scene. There is always room for improvement though. If you want more articles, let me know. If you want more unique content, let me know. The latter of course takes more time and means less frequent updates. Maybe everything is just fine the way it is.

    Fortunately nobody was hurt here and it was just an old Mustang anyway (kidding). This foxbody Mustang was torn apart due to a nitrous bottle exploding in the heat. This is not supposed to happen as bottles have pressure release valves but this valve failed. The result of that was an explosion that sent parts of the car into neighbor's yards. Just a reminder to take nitrous seriously. He's lucky that hundred shot of NOS didn't blow the welds on the intake.

Prior the money transfer they were very responsive and would get back to me immediately. After they received the money which was confirmed by them they became exteremly quiet. No emails. Tried to call them but no pick ups. Im located in Iran, yes that Iran, so there is little i can do. Does anyone know how what should i do? Thanks in advanced
