    Hey guys, The time has finally come to share some details on my secret N54 project. It's been under development for many months now, and had no shortage of both hardware and software (mainly software :)) obstacles to overcome. That said, a major milestone was reached this week so it's time to let you all in! Coming soon to a stock DME near you: Yep, real Flex Fuel. It is a fully implemented flex fuel solution, running on the stock DME! Dial your car in on pump (91-93oct), then E85, set the blending / interpolation curve tables, and be on your way. The benefits here are never having to reflash when changing ethanol blends again (or even worry about mixing the correct blend). Go from straight 93oct to 100% E85 or E98 on the same flash :) This is up and running on a few IJE0S cars now and works flawlessly. There is still some more work to be done, and of course porting to the other ROM types will take a good bit of time. Some hardware details are in need of finalization as well. More to come on those items in the weeks to follow. Some overall highlights and features of this accomplishment: first DME integration with a 3rd party sensor first large scale rewrite and modification of DME logic direct logging of Ethanol Content % in MHD separate blending / interpolation per table grouping seamless blending between maps for any ethanol content I'd also like to give a big thanks to @Chris@CKI for his help in testing and flashing my countless revisions at all hours of the day, and also to @martial@mhd for assembly code and hex conversion help along the way! In case you haven't guessed, this will be a module available in MHD similar to M-Boost. A thread is worthless without pics, right? The log was taken after a fill-up to a higher E content, and you can see the AFR target rising as E% goes up. 2017 is just getting started, and will definitely be the year of the stock DME ;)

    Hey guys, As you saw in another thread, we will be doing testing on all the current intake manifolds on our own dyno, with our E90 6MT GC N54. The car has a built bottom end, ported head with stock valve train, and stock cams. We will be testing various manifolds with the same criteria for each. Once we get this done, we will post all the results here. :handgestures-thumb:

    There is a lot of intake manifold talk on the BimmerBoost forums as of late but there is little in the way of concrete results showing an increase in flow with aftermarket manifolds. EOS (Evolution of Speed) has some results to share with their V2 N54 manifold on a single turbo car. It is important to note that this car makes over 500 horsepower to the wheels with the factory manifold. For N54 owners to see gains they will have to be making a bit of power as the factory manifold is not a huge restriction. At 22 psi of boost the baseline shows 524 wheel horsepower and 515 lb-ft of torque at the wheels. You will note the factory baseline (red) produces substantially more torque from 3000 to 4500 rpm. With the EOS manifold you see a gain in peak horsepower but a drop in peak torque. The EOS manifold is showing an advantage from 5500 rpm until redline which is what produces a gain of 25 peak horsepower. The torque figure drops to 486 at the wheels however. Is it worth giving up some mid-range for top end pull? That depends on the application and goals. More testing is definitely needed on various N54 applications before reaching any definitive conclusions just yet.

    Hello, as the title says, I currently have JB4 and MHD backend with a trebilia custom tune. Im in the process of going with a single turbo setup and i gotta say im not the biggest fan in JB4 much anymore, not because i think its not a good unit, but on upgraded twins i wasnt much a fan of the inconsistency with misfires and would like to spend more time driving vs changing spark plugs and coil packs. So with that said what are some good alternatives for tuning. Cant say im high on cobb neither but it is an option i guess. I would love to have something with a mild pump gas tune for daily driving and a E85 map for whenever i decide to go to the track or whenever i meet up with others for those spirited competitions in mexico lol...

    So in my ~15 years of modding cars I have never posted a build thread. Like most of you US peeps, the weather here blows so I thought I would start a thread outlining my plan of attack to getting my car ready for TX2K this year. But first, let's take a step back... As some of you know, I most recently had a 2008 335xi that I single turbo'd. I did the Doc Race kit, experimented with full E85 and eventually settled on direct port meth as it was my DD and I needed to be able to road trip the car. Even though I loved the car, I hated being held up by AWD and the automatic and the itch to turn up the boost was always there. So in November I sold it and the car went to it's new owner. The new owner was an awesome guy and promised to keep the car in great shape as I did, I hope he is on here reading this! So now a couple weeks go by, I am kicking back and forth different ideas of what kind of car I want to get to replace my 335. I considered everything under $40k but the BMW kept calling my name. I thought about the E90 M3 (too slow), F30 335 (too slow), and ultimately decided to look for a cheap 07-08 335i in manual and RWD. I had to travel to Detroit for business and while I was stuck in the Detroit airport I decided to troll Seattle CL when I found my car. An 07 335i optioned all the way out like my old car, 126k but all maintenance records! I negotiated a deal with the seller, paypaled him $500 to hold the car and bought plane tickets for my and my GF to pick up the car that weekend. We spent the weekend with her family and 10 hours of driving later we were home. Before I even made it back to Idaho I was already ordering parts. But because of the holidays I was only home for a couple days before I had to take off for a two week vacation. I had my friend house sit and when I came home, these are the goodies that were waiting for me. Don't mind the hood in the picture, it's for my Z06...more on that later. Fast forward to last weekend. My GF and I were having dinner with my friend Jake and his GF. Jake owns a LS swapped 72 Chevelle that I tuned. While working on his car we became friends and during that time I introduced him to the awesomeness that is TX2K. Now I've been to TX2K 4 times but always with my Z06. My original plan was to get it ready for this year but the 1500 whp build is taking a little bit longer than I expected. Jake managed to secure us a 42' enclosed trailer in the mean time and during our conversation over dinner we decided fuck it, lets do what it takes to get down there. Now there isn't much I can do to speed up the build on the Z06, but having been to TX2K before, I knew I would be in a tough spot with the car anyway. At around 1000 whp, you are way faster than most of the scrubs that show up there and way slower than the GTR and Lambo crowd. This makes it really tough to find a good race. My second time at TX2K, back in 2011 I went with only 700 whp and I had the time of my life. I was racing all sorts of similar powered cars and met a lot of great people. Why not take the 335i, I said? And that's when the plan was born.. With about 70 days to go, it was time to put the plan into action. At this point I had a lot of the basic shit either in my house or on order: FMIC, wheels/tires, port injection, etc. The one thing missing was turbo. I kicked around a lot of ideas and reached out to a lot of vendors. First thing I did was email Doc Race. I explained my situation, asked if they could hook it up with another kit, etc. They apparently don't want anymore of my money and couldn't be bothered to email me back...thanks guys! Next up was JP Works. I know everyone on this forum hates him, but you can't deny that the price is right and his kits make power. Having been around as long as I have, I knew that to get one of his kits takes 2-3 months minimum so that idea was out. Next up was MMP. I really like Mauricio and really believe in his products. He has awesome communication but ultimately I decided that his Stage 3 offering was price too close to a single turbo kit once it's optioned out all the way and was limited in the amount of power it could make. So what about RB? He just dropped the prices on his turbos into a reasonable range, but not many people seem to be running his turbos anymore so I thought I would send him an email asking if the turbos were in stock, what kind of power they could support, etc. Rob, like Doc Race, also didn't want my money. I was ready to spend $4k+ and all he could write me was "Not in stock and have about a 10-15 day wait sorry."....cool story bro, no wonder no one is running your turbos anymore. Thought about VM, but the wait was too long. VTT was out of the question because I would rather burn my money than give it to Tony. Motiv would have been ideal but I'm not baller enough to afford their stuff. I briefly considered AD Engineering but when building my other 335 I remembered how shitty their customer service was so they were out too. Time for plan B. I hit the forums and started looking to see what kind of used kits were out there. Ideally I wanted a single turbo kit for big power, but beggars can't be choosers and this ain't Chipotle so my options were some Hexons, VTT Stage 2+, and finally a set of rebuilt hi-flow Pure Stage 2's popped up. None of these were ideal, as hybrids can only make high 600's on a good day, but I am in a time crunch and don't have unlimited funding so I picked up the Pures because they are an awesome company and I really believe in their products. So that's where I am at for now...the plan is to go with as close to 700 whp as I can get the turbos to support, hopefully meet some cool N54 peeps, and have fun! More to come....

    An interesting upgrade option for N54 fueling is Fuel-It!'s bucketless LPFP. They have designed a special pick up that allows for their bucketless design. There are advantages here as for one they eliminated the need to modify the factory bucket and they provide a large increase in flow. Fuel It! describes the premise best: There were concerns regarding fuel flow when almost empty but this video addresses those concerns: Now let's look at some dyno results on an E82 135i N54 paired with their Platinum Port Injection kit: That is a solid 600 wheel horsepower with Pure Stage 2's and the AFR is 11.9:1 on an E53 ethanol blend. Definitely something for those looking to upgrade their fuel system to look into.

    Hey guys, I recently took my car to a Dyno and I was happy with the hp, however the torque was not enough. I made 426whp but only 291wtq. Does anyone know what could've caused this? I uploaded a picture but not sure if it worked, anyway, at about 4K rpms the torque takes almost a 90 degree drop while hp continues to increase. I am FBO, fuel it stage 2 fuel pump, e60, map 7. It was a dyno jet, and temp was 70F. So to state clearly, why did I make 500hp (crank) with stock torque? Sorry I don't have logs, jb4 cable doesn't work, I've tried several.

    mj6234 started a thread Sudden Very Rough Idle in N54
    Need some help diagnosing an issue. Went out to my car at lunch and car felt like it was missing, maybe like a coil was bad. Got it home and started swapping parts. Changed all the plugs and coils on bank 2. Still having very rough startup and not really driveable. Did walnut blast 3K ago, never swapped injectors think I have a mix of index 7 & 8. HPFP was done about 20K ago. Got the below codes currently 29D0 - misfire cyl 4 29D1 - misfire cyl 5 29CC - multiple cyl misfire 2E1C - firing cyl 5 Could an injector just go that quickly? Car ran 100% fine this morning.

    Rod bearing wear issues in the 4.0 liter S65 V8 in the E9X M3 are well known. Rod bearings also wear prematurely on the S85 V10 on which the S65 V8 is based but do to the superior oiling system of the V10 the problem is not exacerbated as it is on the V8. Things vary based on use as well. A car that is tracked or supercharged will see more wear than a stock car used for commuting. The bottom line however is that owners should replace their rod bearings before it is too late so that they can avoid what is pictured below. @Michael@GermanAutoWerks shared pictures of a blown S65 V8 from an E92 M3: Unfortunately, BMW has a history of mistakes with M3 engines dating back to the E46 M3 S54 and all the way up to the current F80 M3 S55. Someone should hold BMW accountable for knowingly selling motors with defects.

    2011 m3 was brought to us for a engine noise. When we drained the oil metal was found in it. After pulling the oil pan we found as expected, spun rod bearings. Unfortunately the crankshaft had damage as well. Customer has decided to go the full rebuild route. Out the s65 comes! Have a few special pieces in mind for the new motor including a hardened crankshaft. While everyone else was out celebrating on NYE, we decided it would be fun to pull the motor.

    Talk about entering the M157 scene with a splash! Pure Turbos is not messing around. The proof is in the results right here on a W212 E63 AMG. This is a 4Matic all wheel drive car as it is the facelifted version. In the 26 to 27 psi range of boost output is 840 horsepower. This is with custom ECU dyno tuning from Precision Tuning. Precision did not push the turbos as far as they could to preserve the driveline. What would these turbos make when pushed with an upgraded transmission? Good question. Oh, and how about the pricing? $5995 plus core exchange. That is the best turbo upgrade value in the M157 world right now. As a reminder, before the turbo upgrade and with bolt ons this E63 ran 10.6 @ 133. That was at 670 all wheel horsepower. What will it do now? We can't wait to find out.

    I'd like to force the wastegates to operate conventionally (closed at all times until set boost). My thought process says to bypass the factory solenoids and run the vacuum pump directly to the wastegates, and then use an electronic boost controller to bleed vacuum. Thoughts? Sorry JB4/COBB fans, I'm not going that route.

    So I came across this a few times where on a stock turbo or where the aftermarket turbo snout hasn't been extended or ribbed. The silicone inlet slips off the factory type snout as its to short and has no where to bite on to properly because the silicone pipe rubs on the firewall it tends to come off from the back and forth rocking action of the motor I'm not going to name the vendor here as I want to know if it has happened to anyone else and what brand they have and how many times it has happened. I do have a solution that costs around 5 dollars to make but I want to know how many people have this persistent problem.

    BMWJunkie started a thread M4 DCT Flywheel in 335is in N54
    Its the giving season right? I encourage everyone to share information instead of keeping good info secret, this helps progress the platform. I could of very well kept this to myself and gone faster and no one would of been the wiser. Happy Holidays from BMWJunkie! The Idea: I have been working on David Rooney's 135i DCT swap for awhile now. I am very familiar with the look of and weight of the n54 DCT flywheel. While reading about a clutch upgrade on a f80/82 I noticed a picture of the flywheel in the m3/m4 and it looked much different and much lighter. I was curious and used realoem to inspect weights of the two. The difference was huge. The m4 part rang in at 8.1kg and the stock 335is unit was a whopping 12.92kg! I verified they both used the same bolts, same bolt pattern, thread pitch, and same clutch pack. On paper everything looked great. Located a used m4 dct flywheel from a junk yard and the project was on. The Swap: When the m4 unit arrived I could immediately tell it was a much lighter unit. I verified the splines on the clutch pack were the same and test fitted it onto the crank of a n54 I happened to have in the garage. Everything looked as expected. I pulled the trans out of my 335is and removed the DCT flywheel. The side by side shot says it all. The 335is flywheel is a typical bmw dual mass flywheel and the m4 unit while still listed as a dual mass did not have any noticeable play in it or even look like it was dual mass. It could be dampened internally but I could not be certain. As you can see in the photos the weight difference huge 10.5lbs between the two. The flywheel bolted right up. I used new flywheel bolts and torqued to the m4 specifications. The two cars share the same bolts. The Results: I took before and after free revving videos at roughly the same operating temp and the difference is noticeable. The car felt quicker after the upgrade, no more or less than expected. Worth the 300 dollars to me. I am hoping it will help my launches at the drag strip because I've been leaving too hard with the stock flywheel and 5k launch. I am also hoping this is easier on the rest of my driveline.

    Happy New Year all! After reading all these PS pump pulley horror stories where the broken pulley can lead to the engine eating the belt, I decided to swap out my original engine mounts with the IS engine mounts. I figured stiffer mounts will prevent contact between the pulley and the subframe. But I was wrong. After hitting a deep pothole, I felt some vibrations in the steering wheel and here is the result: Luckily, the belt is still intact and on the remaining part of the pulley so no engine damage there. As a temporary precaution, I opted to use an aluminum pulley instead of the OEM plastic ones: https://www.ecstuning.com/b-hamburg-tech-parts/heavy-duty-aluminum-power-steering-pulley/32427553955~ham/ Since aluminum would bend but not crack it's perfect for this application: It wont let the belt loose even if it deforms. Besides, it is cheaper than the OEM pulley on ECS. My only concern with this is that it would transfer more force to the engine if pulley smashes the subframe again. So I still need to get some stiffer engine mounts. I am currently looking at AD Engineering and Black Forest Engineering mounts. Does anyone have any experience with these? Are there any significant NVH increase with these? Does anyone have any additional recommendations? Thanks everyone!

    2016 2016 was a great year for us at VTT. Not only did we release the GC family of fully-cast and modular turbochargers for the N54, but we saw growth in literally every single aspect of all VPG subgroups (VTT, VPP, VHP) by continuing to innovate. Bragging a little here, VPG was the first on the N54 platform with... -billet compressor wheels as an option across the entire lineup -upgraded thrusts as an option across the entire lineup -N54 OEM rebuilds -N54 stage 1 turbos -N54 stage 2 using factory style bearing housings -Clipped turbine wheels in an N54 application -9 blade turbine wheels in an N54 application -19T/20T compressor wheels in an N54 application -Stock location silicone upgraded inlets -Silicone hot side charge pipes Continuing the trend of innovation, in 2016 we… -Released fully cast and modular high flowing twin turbo upgrades (our best dyno was 785 whp!) -Developed and released a 750+ whp capable DI only fuel system and controller Performance wise? In 2016 we... -made 777 whp DI only (GC's, double barrel shotgun and controller) -trapped 169.9 mph in the 1/2 mile (6MT, full weight) -ran 11.0 @ 136 mph in the 1/4 I(6MT full weight) -competed at 4 organized runway events in Oregon, CA, and AZ -visited the (local) 1/4 mile track more times than we could count -gave away 2 sets of GC's, multiple inlets, and plenty of VTT swag 2017 2017 is looking to be a promising year for us and we're excited to get rolling on it. Our top secret plan is pretty simple; focus on our strengths, keep innovating, and push the development on the platform far and hard as we can. On our menu will be: -continued development and testing of the BB solution for twins -continued development and testing of GC+ turbochargers -Pushing the NIZPRO auto transmission as hard as we can and unleashing it at the track -come on now you don't expect us to tell you everything do you? We have a few more projects going on behind the scenes -More giveaways -More articles -More VPG contests (including challenges!) All that wonderful news but how does this effect you, right now, today? Price drop. New 2017 Prices: -GC pricing is now $3999 -GC lite pricing is now $2999 -Single Barrel shotgun pricing is now $799 -Double Barrel shotgun pricing is now $999 (website is in the process of being updated -expect it to reflect the new prices shortly) http://performance.vargasturbo.com/bmw-products/n54/

    Some of you may remember my prior post on my 335is clutch swap experience. Anyway that was done at roughly 45k. We'll I just hit 74k and just swapped out my 335is clutch because of the following symptoms. Audible rattle when car not in gear and clutch not pressed. Rattle would go away when clutch was depressed. Sticky clutch after high rpm runs or heavy braking. I came to the conclusion it was the throwout bearing and decided it was time to do the swap again, I went 335is clutch again since I never had any slippage occur. Anyway the swap has been documented enough. This time around I did the following parts. MFactory SMFW (really nice part) 335is clutch brass pivot pin lots of new bolts Brake fluid rbf600 redline mt90 fluid Rear main seal 335is motor mounts oil filter housing gasket and oil cooler gasket (was leaking like a champ) New coolant block hose fitting since I BROKE THE CHEAP PLASTIC SH!T. (http://www.ebay.com/itm/BMW-335i-11537541992-OEM-WATER-HOSE-FITTING-REPLACEMENT-ALUMINUM-6061/182218057115?_trksid=p3693.c100102.m2452&_trkparms=ao%3D1%26asc%3D20140212121249%26meid%3D47e1b78c0d254d669cbbe9f78a2f1c56%26pid%3D100102%26) Quite the part list but I got it done working a few hours at a time over the course of a week. I have my own lift so this makes the process quite easy :dance:. The aluminum hose fitting was dope and fit perfectly. When i removed the original plastic fitting from the block to get the oil cooler off I gently pulled it out and quickly found half of it was left attached to the block. *FYI https://www.ecstuning.com/b-genuine-bmw-parts/coolant-outlet-hose/11537541992/ is the part that broke. If you want metal save yourself a headache and downtime and replace either this part or order the aluminum fix. Back to not breaking things. With the tranny out I saw the clutch and pressure plate looked perfectly fine. The clutch looked brand new honestly. So that's good to know. FBO + inlets, trapping 150mph in 1/2mile, many miles of abuse, no slipping, 450rwhp plus, many 1/4 mile runs and it looks great after 30k miles. Pressure plate and forks on it look good as well. The throwout bearing had a different rattle than the new one and just felt worn out. Leave it to BMW to make plastic parts. So I ripped out all the flywheel and clutch parts and did the rear main. Thanks to Vargas and folks giving info on how to change this out. It's super easy and worth the 5min it takes. Self-tapping screw into old rear main, pull out with hammer push new one in evenly and flush, use Gasket maker of choice and do a thin covering around block to gasket(2x insurance) Mine had no leaks prior but now I'm sure it wont any time soon. Buttoned it all up and the car runs perfectly fine with the clutch issues resolved. While I had the transmission out I did take the time to look at the shifter slop that I hate. I decided to shim the space between where the clip holds the selector rod on, So I took a half moon shaped shim and pushed it into the space between the clip that holds the selector rod and the shift rod. Below is the clip i'm talking about but I still have the stock rod. Anyway it cleaned up some slop and didn't cost me anything. Notice the black dot, thats where I pushed the shim in, this is not a 335i image just an example. I can take pics of the old flywheel and clutch if anyone is interested. But like I said the clutch looked brand new. mfactory SMFW high res new rear main seal high res old rear main high res trans bellhousing brass pivot pin high res new clutch and pressure plate high res

    Hey everyone, So I'm not sure if this has been brought up before but I follow a couple interesting aftermarket companies and this is what I found from one of them: https://www.pureperformancemotorsport.com/index.php/bmw-n54b30-335i-turbo-billet-crankshaft.html Has anyone heard of a snapped n54 crankshaft? What's the need for this? I thought the n54 couldn't use different crankshaft due to the design? Thanks, Brandon

    For anyone waiting on their JPWorkz kit, they are shipping out, slowly but you'll get your kit. (Old order #146 , #1007 in the new system) Took just over 3 months to get it. Still missing a couple of items, but the bulk of the kit is here.

    Uh oh, this has to be a warning sign at BMW. A drop of 10% in sales in 2016 compared to 2015 is large. BMW's are selling obviously as 313,174 cars is a lot of volume but that number was 346,023 in 2015. Perhaps the signs were there early in the year when Mercedes and Audi started the year with much stronger sales than BMW. Perhaps consumers are getting tired of BMW? Perhaps BMW has lost some of the enthusiast market? Keep in mind BMW equates sales figures with how well they are doing. They feel if they are number one in sales that means they are the number one brand. It's illogical as volume does not equal quality but that is the official BMW brand position. Just because one brand outsells another does not mean it builds better cars. For BMW this must be a bit of a shock considering how hard they are trying to push volume above all else. That is why you have so many variants of platforms namely in the X-Series line. Additionally, the new 7-Series launch should have further bolstered the bottom line. Table 1: New Vehicle Sales BMW of North America, LLC , December 2016 Dec. 2016 Dec. 2015 % YTD Dec. 2016 YTD Dec. 2015 % BMW brand 32,835 34,625 -5.2 313,174 346,023 -9.5 BMW passenger cars 20,419 22,818 -10.5 209,231 244,767 -14.5 BMW light trucks 12,416 11,807 5.2 103,943 101,256 2.7 MINI brand 4,658 5,009 -7.0 52,030 58,514 -11.1 TOTAL Group 37,493 39,634 -5.4 365,204 404,537 -9.7 When Mercedes and Audi release their figures we will know if either or both of them took the crown from BMW in 2016.
