    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

    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

    New stock turbo World Record :music-rockout: Well got it done today as promised with Terry helping me dyno tune. 80F rainy and muggy outside, plenty of humidity, and it didn't matter, got the new WR thanks to the MMP turbo intakes! Will post more data later but here is the dyno picture for now. This was on my own personal daily driver car with 90k miles on it, 2007 6AT 335i coupe. Also ran leak down on it recently and 2 cylinders are at about 20% so not the most power producing engine out there ;) A healthier engine will definately see more power. power mods: MMP turbo intakes JB4 custom tuning backend and user settings fuel it stage 2 LPFP dual meth injection DPs without cats Big Tom intercooler TFT charge pipe custom 3" intercooler up pipe NGK .022" gapped spark plugs fuel: straight E85 run 21 is 4th gear, run 23 is 5th gear. oh and this is on a 6AT with 3% more drivetrain loss than MT. Adjusted for MT drivetrain loss, this would be 512whp Previously I had my car tuned to the absolute max on the dyno and my results in 4th gear was 447whp and in 5th gear was 456whp. I was running 100% E85 and the same amount of meth. All I did was change to the MMP intakes and dyno tune for the added performance of these inlets and I made 490whp in 4th and 500whp in 5th. That is a delta of +43whp in 4th and +44whp in 5th, pretty consistent. Also if you look at the logs where max HP is made for each Dyno pull, this is done with a delta of 3psi for these gains, pretty awesome gains for only 3psi! Also the conditions on the dyno prior to inlets was a Density altitude of 1208 ft and on the dyno day with the new inlets was 2873 so alot worse in DA, it was a hot muggy day, I told Terry I didn't think we could hit the record on that day but he urged me on to keep the dyno appt, glad you did Terry ;) So with the same car, maxed tuned for each setup, on the same dyno, and with worse conditions, here are actual deltas and results, not speculations based on different cars, different drivetrains, different dynos, etc, etc, etc leading to bad conclusions below is the comparison plot of max effort dyno comparison pre and post MMP intakes all else equal. And here is the log for the the dyno pre MMP intakes with max effort tuning And here is the log for the dyno post MMP intake installation with max effort tuning As you can see, before The top end is where the MMP intakes shine and net +44 max whp and + 56 whp at 6k rpm and also broadened the power band by shifting the max hp up by 200 rpm and alot more area under the curve. You can see from the dyno logs before MMP intakes WGDC was 100% maxed out at 5500 rpm on and only holding 20.8psi taper to 16.5psi, after MMP intakes WGDC only gets to 86% at 5700 rpm and able to make 25 psi, taper to 21.6 and back up to 22.6. This clearly shows with Dyno data and logs that there is a HUGE performance gain on stock turbos by upgrading to the MMP intakes!

    After many months of testing and thousands of miles now logged on our first few kits its into full production mode. We are also proud to announce a much lower price of $5999 for our 62mm "Hot Side" kit. A few things allowed us to do this... better buying and pricing on larger quantity orders have brought cost down, but the biggest change is the intake. The original kit included a high temp resin carbon fiber intake. However, the producer of the intake was not reliable and after not being able to find a new outlet to produce them we made the decision to step away. The intake is now a 6061 aluminum mandrel bent intake with the K&N filter still located behind the left headlight. I really wanted the CF intake, but it looks to be a blessing. No longer including a CF intake paired with parts savings has dropped the kits' price almost $900 without sacrificing quality, fit, or performance. http://www.ad-eng.net/store/p25/AD_Engineering_BMW_N54_Single_Turbo_Kit_%28_135i%2F335i_%29.html Keep an eye out as we add the AD Engineering Intercoolers and Catch Can over the next few weeks

    Hi! I have a JB4 and a single turbo installed with all supporting mods on an 07 335i. I ran the single turbo backend flash, and the flash went flawlessly and the car ran well. No flashing issues. Recently, I had my tuner adjust some timing values and send me a new bin file. I tried that backend flash on my Macbook, and upon trying to write the ECU, it says that the flash failed and that it would not authenticate the control module. The fuel pump ran continuously in this process. I disconnected the battery for 5 minutes and repeated this process 5 or 6 times. Same issue every time. What should I do to get my car started? I am home for the weekend and have a business trip I have to make on Monday (oops). Right now it will not start, and when I turn the ignition on, the fuel pump runs continuously, regardless of whether or not I am connected to BimmerBoost. Any and all help is greatly appreciated!

    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

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 )

    Wondering if anyone here has experience working on their cars under a 4 post ramp-style lift? I'd have a jack-tray to raise the chassis while on the lift as well. I'll be using this lift to install a turbo kit, as well as other tasks on this vehicle and others. The drive-on diamond plate ramps are 18" wide with 37.5" gap between ramps for work access, and being 175" long, I can have the vehicle on the ramps away from the end cross-member. I realize that a two post lift offers the best access to a vehicle and suspension, however there are some limiting factors in my situation: - I have infloor pex tubing and would like to avoid drilling concrete, my pad thickness is at the bare minimum (4") - I like the idea of having casters and storage potential under a 4 post - I only have 11' ceilings

    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. With this system in place, we feel it should not only increase our enjoyment of the forum, but make it a much more enjoyable place for all. It is no secret there is no love lost between some of the vendors here, so we will take a stand to try to bring BB back to a place where there is less drama, and more useful information. If you have any positive comments, or suggestions, feel free to post them. If you have negative things to say, keep them to yourself, or start your own thread, we do not want it posted here. Thanks, enjoy your Sunday! VTT

    The McLaren P1 versus the Porsche 918 Spyder. Both of these cars have carbon fiber tubs and body panels. Both have small displacement, high revving V-8s packed between their passenger compartments and rear axles. Both use twin-clutch transmissions, carbon ceramic brakes, and active aerodynamics. Both have roughly 900 hp. Both are plug-in hybrids. And today, with the help of pro racing driver Randy Pobst, we find out which one is fastest around Mazda Raceway Laguna Seca.

    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.

    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).

Yes, the Porsche 991 generation Porsche 911 Turbo is slightly more powerful at 530 horsepower and 483 lb-ft of torque from its 3.8 liter twin turbo flat-6 than the AMG GT S with its 510 horsepower and 479 lb-ft of torque 4.0 liter twin turbo V8 M178 powerplant. Recently, we witnessed the AMG GT S just easily pull away from a Porsche 911 Carrera 4 GTS as it should considering the 911 GTS is just overmatched. Based on the specifications alone the 911 Turbo and AMG GT S should be a pretty close fight considering the the power is very close between the two and the AMG GT S is sending its power to the rear wheels and not all four. It is also a brand new chassis and also features a dual clutch transmission. 0-60 figures of course will favor the all wheel drive 911 Turbo and they do at 2.9 seconds to the AMG GT S 3.7 second sprint. What is truly is puzzling is the 911 Turbo is just over a full second faster to 124 miles per hour than the GT S. It is almost a full second faster to 100 miles per hour as well (.9) so its advantage is actually increasing with speed. What else is odd here? The 911 Turbo is lighter. Autobild weighs it at 3567 pounds and the AMG GT S at 3679 pounds. Why the AMG GT S is that heavy when it is rear wheel drive and fairly compact is a mystery to us. Ok, fine, but what about performance around the track? The AMG GT S is absolutely destroyed on the Nurburgring Nordschleife turning a 8:10.10 minute laptime compared to the 991 Turbo 7:59.20. Keep in mind these are not hired guns from the manufacturer extracting laptimes but a difference of over 10 seconds between the cars? Really? It's not just the Nurburgring either, the Sachsenring time for the 911 Turbo is seconds ahead as well: This test just does not feel right. We're not saying Autobild is misleading anyone or anything of that sort but we definitely want to see more comparisons from other sources.
