    In the N54 world there are three transmissions mated to the motor as sold by BMW. There is a manual 6-speed, dual clutch transmission, and an automatic from ZF (ZF Friedrichshafen AG) which has six speeds and has the model name 6HP21. High power N54's have thus far been relegated to the manual transmission as the clutch can easily be upgraded. The dual clutch transmission is in far less N54 powered cars and although upgrades are available the amount of DCT guys pushing big power with a huge single turbo for example is relatively small at least as it pertains to N54 motors. The odd man out has been the automatic yet it is numerically the option with the most cars on the road. Why? Why has the automatic been so tough to upgrade? Well, there are a few reasons. For one, nobody has (until now) cracked the TCU or transmission control unit. Additionally, even if you have software control of the transmission there really are not any serious material upgrades that can hold big torque from say a big turbo kit. Oh, sure, people will point to Level 10 transmission upgrades but the reality is Level 10 is only an option to replace factory parts and get a broken transmission working again. They have never demonstrated an ability to hold the kind of power the manuals hold. That is where Propulsive Dynamics comes in. Their proprietary G3 material works in concert with Kolene Steels, a proprietary patent-pend bi-metallic bushing alloy and increased surface area in the holding clutches, to result in an increase in holding capacity of 30.4%. This friction increase is not some number pulled out of thin air but a result of SAE (Society of Automotive Engineers) testing. Pretty awesome stuff, right? There is much more information to come but for now rest assured automatic N54 fans that a serious upgrade that can handle whatever you throw at it is on the horizon. That means we will finally see N54's take that next step forward especially when it comes to times on the drag strip. Is 2016 the year of the N54 automatic? It sure is shaping up that way.

    Hey Everyone, Itís about time for some exciting announcements from VTT. This has been a long time coming! As most of you know, I've taken over online representation for Vargas -but that's not the only thing I do for fun. The overarching announcement is that VTT is now one piece of a bigger group; Vargas Performance Group, or VPG. There are 3 major parts of VPG: 1: VTT (Vargas Turbocharger Technologies): Turbocharger Manufacture/Repair/Upgrades/Sales 2: VPP (Vargas Performance Products): Performance Parts Manufacture/Sales 3: VHP (Vargas Hi Performance): Turbocharger & Performance Parts Installation/Service Iíll quickly go over some announcements as they pertain to each category: VTT NEWS GC's: This is the one many of you have been waiting for. You know the ones -the stock location twin turbo setup that made 736 whp. Just look at the power under the curve! Street spool will be even better! The VTT GCís have started arriving and the first sets have shipped. We expect a second shipment shortly and the remainder of them by the first week in June. The plan is to quickly get caught up on all existing orders and soon after be in a position such that they are available for same day shipping. Note for those who got the ceramic coating; as of this week, itís adding around a week to the ship date. Bundles: GCís can now be bundled with installation ($1000 for inst. labor at VHP, more on that later) and/or a PTF tune ($249 for a MHD tune, $499 for a MHD tune with PI) 93 Octane Testing: I know there are some unfortunate souls out there who don't have access to E85 and for whatever reason don't want to use methanol. For them, we WILL be doing some pump gas testing. Expect this late 2nd quarter/very early 3rd quarter (read that: around July).I don't even want to speculate on dyno numbers -we'll find out while testing and post those results. VPP NEWS Vargas Performance Products. These are all teasers -think of this post as a quick look into the VPP crystal ball looking forward. Here are a few things in the works for VPP and one thing we're just too excited about not to share: Line Lock Kit: Here are a couple development pics -not final config by any means. This will fit all E9X and E8X, not sure about 535's or Z4's -we'll be looking for testers there down the road. Port Injection Plate with Top Mount Injectors: Anyone say they wanted an N54 port injection kit with top mount injectors? We heard you, and we agree -if you can fit them, top mounts are worth doing. We can and we are. ~3rd quarter 2016. S55 Love: We're not just playing with N54's here... the S55 gets some love too -how about some port injection (bottom mount -no room up top)? Oh, and GC's for the S55 are already in process -very late 2016/early 2017 release on those. Transmission Fun: By now everyone and their grandmother has heard the awesome news about Nizpro and the magic they're doing with transmissions. We're working directly with them and will have one the first fully built and flashed transmissions from them. While this (obviously) isn't a VPP product, we're very excited about this and have some high hopes for this really being a huge jump forward for the platform. VHP NEWS Wouldn't you rather have your turbos installed by the same guys who made them? A shop that understands turbos and has 100+ installs under their belts? If you're within driving distance of Hayward, CA, you can buy turbos, schedule an install, and have VHP install them for $1000 labor. Of course you still need to buy your gaskets (we have an installation kit for $230) and do an oil change while you're there, but it makes for a pretty good deal -especially after the GC's are in stock and available same-day. OTHER STUFF Expect more updates with more products, more accurate ship-by dates and more options for everyone. And I'm just getting started... Chris

    Here is the scenario. You work overseas and have a Porsche 996 Turbo. You see a classified ad go up from Vivid Racing for a 4.0 liter stroker short block advertised with a new crank, new pistons, new rings, new Darton sleeves, new gaskets, etc. Sounds good right? Especially considering the advertised $10k price is less than doing this all yourself and assembling all the parts and having the block sleeved. So what is the problem? The customer did not get what was advertised: Basically, what was advertised as new and in great condition simply was not true. Not to mention the scuffed and rusted liners with marks in the flange which he asks Vivid to replace. Vivid says Darton is responsible and Darton says they sold this to Vivid over 2 years ago and who knows what happened since then. Darton is right in this instance, they can not be expected to replace parts Vivid messed with or did not store properly. The solution here is very simple. Vivid should replace the parts, right? Well, they didn't. Rather than replacing the damaged sleeves Vivid is willing to sell more at cost since Darton won't be suckered into paying for Vivid's mistakes and should not be expected to. Vivid knew they were selling something that was not brand new and perfect as advertised and they just wanted to pass this onto a sucker who would have to shell out more out of pocket to get it working. That line about exceeding customer expectations and satisfactions is just a load of horse shit or a sick joke. This is honestly nothing new with Vivid. They will exaggerate or misrepresent things to make sales. We have seen it before such as when they claimed 407 wheel horsepower from a BMW S65 V8 with their tune on a Mustang dyno which is impossible unless one messes with the correction factor which they clearly did to exaggerate the capability of the tune they were selling. Vivid is all about making money and they do not seem to care how they get it. They basically just ship a lot of parts to a lot of people. It's why they acquired the HPF (Horsepower Freaks) name to simply utilize another brand to ship more and more parts from their warehouse. The bottom line is they don't give a crap about their customers and won't do the right thing if it means money out of their pockets. Think this is an isolated incident? Read this 60 page thread on Vivid's business practices which goes from praise to horro stories in a hurry: Why do people keep going to them? Caveat Emptor.

    Just want to say thank you first of all to all owners of our single turbo and also to all supporters. The response and feedback have been great and I am glad to say this is personally my favorite product I sell here. I take great pride in each and everyone of these kits that leave my shop. So there are a good amount of kit owners now out there. Some Bimmerboost members and some not but all can play. I am giving cash prizes for anyone with our kit that can provide us with dyno sheets and videos. I hope this will help promote our kits as well as help anyone trying to stay in budget for their builds, I know how pricey things can get. The prizes are listed below and to redeem I will need you to email me with a list of parts you have on your car as well as a dyno sheet, a video, and a picture of your engine bay. I'm sure there are a few of you that are close if not ready to redeem a prize, come and get them:music-rockout: $100- Dyno video/sheet showing 600whp+ $250- Dyno video/sheet showing 700whp+ $500- Dyno video/sheet showing 800whp+ $1000- Dyno video/sheet showing 900whp+ $1500- Dyno video/sheet showing 1000whp+

    Posted this on N54tech, but figure it would get more response here. Planning to upgrade the stock snails in the foreseeable future. But aside from the usual quality control issue with the CHRAs that gets vented on these forum all the time, the wear rate on the wastegate assembly (flapper valve and pivot bushings to be more specific) on these stockframe turbos is a bit of concern as well. From my understand, the excess wear and eventual play, which causes the awful rattle that high mileage N54 is known for, is mostly due to the actuator setup on these turbos. Instead of staying close at idle and low load scenarios, the wastegates on our turbo would stay open and only fully close during spool. This demands a lot of back and forth movement on the assembly over time and leads to the rapid wear on the stock assembly, and even on the so called upgraded ones on the aftermarket ones. I mean, come on, how come wastegate rattle and excessive play is so common with n54 turbos, but not nearly as much on other platforms's OEM turbos with internal wastagates that have been around even longer(VAG, Evo/STI, etc.) So why don't we just convert the stockframe wastegate to the usual setup, by using mac solenoid used for the single turbo setup, and an aftermarket wastegate actuators like one of these ( Can imagine this would be a difficult thing to do, since one only need to modify the existing brackets for holding the stock actuator, and fabricate the pushrods connecting the actuator to the wastegate lever. So here are my questions - How can we set up the vacuum line for this to work? I suppose we can just bypass stock boost solenoid all together and hook up the MAC solenoid, the one that is being sold on BMS with the PnP adaptor, directly to the WG actuator and the vacuum pump. - The diagram on the N54tech thread ( shows that the vacuum source is the inlet port of the turbo compressor, which doesn't produce a constant vacuum pressure, instead of the vacuum pump, which does. Would that affect things? Please guys, don't convince me to go single turbo instead, lol. As much as I like having incredible top end and ridiculous amount of peak hp, I have plenty of reasons to stay with stockframe hybrid and below 500whp instead. Hell, I don't even plan on installing inlets, lol.

    These are some very quick numbers as recorded by EVO magazine. Magazine times and actual drag strip timeslips are quite different but these numbers are not shocking considering what the F80 M3 and F82 M4 are capable of in stock form on the dragstrip. The M4 GTS takes the standard M4 recipe and improves on it by stripping out a couple hundred pounds thanks to extended use of CFRP (carbon fiber reinforced plastic). The S55 engine also gets a water injection system and a power bump to 500 horsepower. Considering the standard M4 S55 motor is already making in the 500 horsepower range with dyno results showing 427 to the wheels the M4 GTS is likely at 450+ to the wheels. Despite the additional aerodynamic drag caused by the wing which increases downforce the M4 GTS accelerates very well. Under 8 seconds to 100 miles per hour was supercar territory not too long ago. Do these test numbers make the car worth $134,200? No way. Throw a tune on your M4 and be done with it if acceleration is what you are after. Actually, maybe hold off accelerating in an S55 equipped car entirely considering the engine issues.

    Hey guys, It seems that there are more and more reports on rod bearing failures so I am starting this thread to understand which factors correlate the most to failures of rod bearings in N54s. As our engines age, this may be an impending issue if we don't address it. I am hoping to collect data to find the common factors to this issue which will help us prevent it. The most obvious factor is oil dilution. Please read this if you want to know more: So for those of you who had rod bearing failures please answer the following questions: Which N54 car do you drive (Model and Transmission) Miles on the car/engine when the rod bearing failure was detected What HP/TQ were you running when you detected a rod bearing failure (Name the modifications if you don't know.) How many miles were you running the previously stated setup What tune / who tuned Did you have leaky injectors What fuel did you run Did you often turn the car off before it reached operating temperature (short trips) Did you idle the car a lot What is your OCI (Oil Change Interval) What kind of oil and viscosity do you use External factors (e.x. Shop forgot to put oil back) Much Appreciated!

    It was a fun day overall, but a complete waste of $100. I got about 4 laps in before blowing off a charge pipe that ended my day. It was fun though, would've liked for the rain not be fall down on the track, but I don't complain about rain! As usual the fastest cars there had the slowest drivers.

    Great numbers here and he Doc Race single turbo kit for the BMW N54 motor continues to impress. This particular E92 335i is running a Comp 6267 turbocharger and boost is 23-24 psi on a 93 octane and methanol map and it goes up to 26 psi on an E30 tuned map. Here are the specs: 132k miles on the clock -93 and meth map is 23-24psi -the E30 map is 23psi ramping up to 26psi at redline. -100% Meth on both maps Mods: -Doc Race Twin Scroll manifold -JB Comp 6267 -JB4 -BMS Meth Kit -Boost Addictions Custom Calibration Very solid numbers here and obviously the methanol is a big part of it. With the meth it is possible to have an easy 600+ wheel horsepower 335i daily driver. The Doc Race kits continue to impress and reports thus far are of quality fitment and parts. Definitely a solid option in the crowded N54 market.

    Hey guys, Spent a couple hours on the dyno today with our 2012 335is DCT development car. The car is 100% stock except for a dual cone intake. The car is running 91 octane fuel with no octane booster or E85 mixed in. Otherwise known as the worst gas you can tune for. All runs done in 5th gear. Temps in the 70s. First up was testing on the stock tuning for a baseline. The JB4 was installed by in "flash only" mode for logging purposes only. e.g. white subconnector left stock and JB4 on mode 4/4 so it can't influence the tuning at all. I was surprised by how choppy the timing was on the factory tuning. That's 91 octane fuel for you. I've seen the 335is factory tune go anywhere from 315whp to 335whp on 93 octane so we're at least in the ballpark here. Since the car was in "flash only" mode I decided to give the MHD v6 Stage1 ACN map a whirl. We frequently test competitive maps to ensure our customers are getting the best product available. In this case the off the shelf flash map was disappointing. We work with MHD on back end flash stuff and always look to maintain a positive relationship so I'll leave it at I think this specific map needs more work. Next up I flashed it back to stock, reinstalled the JB4 in full control mode, and grabbed a few runs on JB4 map2 and map5. I failed to capture one in JB4 only map1 although as I'm writing this I wish I had. Results were about as expected. Good power across the board with timing drops fairly similar to the stock mapping. If I had taken the time to do more runs on map5 I suspect it would have detuned itself a bit. Finally I loaded up the ina0s PUMP back end flash map and did a couple runs on JB4 map1. After these runs I spent another hour working on ina0s BEF improvements but I'm not quite ready to share info on that yet. But as a cliff notes I was able to get timing a little more stable and fix the torque limiter causing timing to go negative at 3000rpm. Still, these runs/logs on the currently available map provides a good indicator of where the JB4+BEF 91 octane DCT tuning is currently.

    Hey everyone. I have a 2013 BMW 335i xDrive F30 N55. I am looking into the JB4 for my car but I cannot seem to understand which type I need. This is what I am looking at: // It shows me on the website to see if I have a A type or B type. It looks like I may have a B type harness but when I go to select an option. Those types are only for 5/6/X series... I have a 3 series so it's asking me if I have a Pneumatic or Electronic Wastegate. And thus I am confused. Please excuse my lack of knowledge and if someone could clear this up for me I would be very grateful lol

    The Formula 1 Monaco Grand Prix is always interesting and the 2016 iteration certainly delivered. The race did not start in exciting fashion as rain was coming down and the safety car stayed out for the first seven laps of the race in the interest of driver safety. Finally the cars were allowed to go at it as the rain subsided and immediately Red Bull's Daniel Ricciardo who had the pole position started to build an impressive lead. Nico Rosberg of Mercedes-AMG was in second place but consistently lost ground to Ricciardo while holding up teammate Lewis Hamilton. For whatever reason, Hamilton looked much faster and Rosberg looked slow. Rosberg was so slow that the commentators speculated something was wrong with his car. As Monaco is a tight course Hamilton struggled to get around Rosberg who finally was told to let Hamilton by. Immediately Hamilton started to make up ground while Rosberg fell further and further back. Because Rosberg held up Hamilton Ricciardo built himself a nice 10+ second lead. It would all evaporate (heh, get the pun?) after a Red Bull pitstop that went horribly wrong. Tire management was huge in this race as with the track conditions drying up and the sun coming out drivers began to switch to softer compounds. The only problem is that when Ricciardo came in to switch his tires his tires were not there. He literally sat there waiting for roughly ten seconds until the tires were brought out. Well, this gave Hamilton the lead. Ricciardo did not quit and kept at it but Hamilton fended him off. There was a questionable situation where Hamilton cut a corner and blocked Ricciardo which could have been the difference with the difficulty of passing in Monaco but the stewards dismissed the incident and did not penalize Hamilton. He would go on to win the race. The conditions claimed many victims. Max Verstappen (the much praised Red Bull driver who became the youngest to win an F1 race in the previous Grand Prix) crashed out. Kimi Raikkonen, Jolyon Palmer, Felipe Nasr, Daniil Kvyat, Kevin Magnussen, and Marcus Ericsson did not finish the race. Lewis Hamilton would end up celebrating while Daniel Ricciardo said he got screwed. He was quite upset. Sergio Perez who finished in third and held Sebastian Vettel from the podium was quite pleased with himself. It was an interesting race to be sure and it drew out all kinds of celebrities including Justin Bieber who for some reason was celebrating with Hamilton which looked awkward to say the least. Next up is the Canadian Grand Prix on June 12th.

    Whoa there McLaren! Not so fast. This talk coming from McLaren boss Ron Dennis sounds pretty good. He said, "I honestly believe that the next world champions after Mercedes will be McLaren. We'll get to that goal before other people." Will they though? McLaren has not won a race since the Brazilian Grand Prix in 2012. Mercedes-AMG won the Formula 1 championship in 2014 and 2015. Is this year really shaping up any differently? The only thing that stopped Mercedes-AMG from winning the last race was their own drivers crashing into each other. The upcoming Monaco Grand Prix this Sunday is only the sixth race of the calendar so it is more than mathematically possible for someone to catch and pass Mercedes-AMG in the standings: It just does not look like it will be McLaren that does it. Only Ferrari and Red Bull seem to be putting up any kind of fight and Mercedes is still dominating. Realistically, McLaren doesn't have a shot until next year and Ron Dennis knows it. Plus, Honda really needs to improve their motor. Good luck with that. Source

    We all know the Bugatti Veyron is fast. It basically is nothing more than a straightline missile with its 8 liter W16 quad-turbo engine making 1000 horsepower and up to 1200 depending on the model variant. It doesn't matter if this Veyron has 1000 or 1200 as it gets embarrassed. The Agera S has similar power 1030 horses from a 5.0 liter twin turbocharged V8 but it is just so much lighter than the Veyron. No all wheel drive and and what they call a 'dual clutch' with 1 input shaft are not a detriment for the Agera which is roughly 1400 pounds lighter. This is just old fashioned power to weight doing the work. Keep in mind as this is a Swedish video and the Agera is a Swedish supercar the person recording likes to promote Koenigsegg with a Swedish bias. To put it frankly, watching these Swedish videos of a Koeniggsegg always winning is getting kind of boring. Maybe it's time to run some real competition? Regardless, the Veyron is simply overmatched by the Koenigsegg here which we already knew (and have seen).

    On paper this is a huge mismatch. The 997 GT2 RS model makes 612 horsepower and 516 lb-ft of torque from its twin turbocharged 3.6 liter flat-6 motor. Not to mention it weighs 150 pounds less than a standard GT2 coming in at 3085 pounds. The 991 generation 911 models do not have a GT2 variant. They do have the GT3 RS though which has 500 horsepower from its naturally aspirated and direct injected 4.0 liter flat-6 along with 338 lb-ft of torque. It's 22 pounds lighter than a 991 GT3 coming in at roughly 3150 pounds. The GT2 RS has a ton more power and torque and it weighs less. The only wildcard here is that the GT2 RS has a manual transmission and the GT3 RS has a PDK dual clutch transmission. They run a few times and the GT3 RS seems to get the jump each time. The GT2 RS owner looks like he can use some help shifting. The GT3 RS gets a nice lead only for the GT2 RS to come back and pull like crazy up top. With an even start this isn't even a race. The PDK certainly helps things down low. Regardless, the GT3 RS is not made for straight line racing. It's still fun to see the difference between the two.

    Ok, ok, relax. This isn't going to happen. What if it did though? BMW for fun built an E92 M3 truck as a joke and an actual shop replicated the feat although in higher quality fashion. BMW has roughly a billion X-Series variants so what would a pickup truck hurt? For the American market, where most X-Series models are built and consumed, a truck makes a lot of sense. Especially if based off a chassis that can actually tow and haul to a useful degree. BMW builds stuff like the F07 5-Series GT that people don't want and BimmerBoost would bet money an X4 pickup would sell better. It's certainly fun to think about.

    I'll be heading to the track this July in Austin, TX, with my BMW S1000RR. It has a bunch of heated amenities, but still lacks A/C. It's going to flat out be hotter than the devil's rectum (Mad respect for whoever can name the video game reference). I am planning on purchasing a cooling vest to wear under the leathers, and have 2 choices that I want your advice on, from a scientific point of view. The evaporative cooling vests are cheaper, and function by soaking them in water, then putting them on. I'll be traveling between 40-180mph for the most part, so airflow will be good, but the humidity will be high, so the evaporative power will be quite limited. My other option is a freeze puck vest. Freeze it overnight and on breaks, then wear it. This cools me, obviously, by having cold water touching me. The puck vest is slightly more expensive, and may not last as long when exposed to the extreme heat. I'll have 40min of time in between sessions to freeze the vest, but only a mini-fridge to do so with, so it may not even get frozen between runs, which would render it close to useless. Ideas? Thanks!

    It's been a great run guys and we have discounted well over the initial 20 kits as promised. The promotion is ending soon but you still have some time. I'm going to extend the promotion till June 30th so that gives exactly a month to get one of these in your hands in time for summer:auto-layrubber: Build time on these right now is about 2 weeks and we are trying our best to have them back in stock.
