    VTT is proud to announce our new cast turbocharger samples arrived today. I can say seeing my vision, and direction put into motion, and finally seeing a working production turbocharger is a really great feeling. These turbochargers we hope will shape the landscape of the N54 turbocharger market, and we are happy to share them with you, bringing you a true stock frame location turbo with no compromises. We will be installing, tuning, and testing these in the next couple weeks, and once we have the data, and numbers. We will be making a full announcement thread, with pricing, availability, buy back incentives, specs, as well as our plans for a giveaway. Until then, here are a few photos, we will post some more one we get it on the engine, and installed! Stay Tuned, things are about to get interesting...:music-rockout:

    jyamona@motiv started a thread DI Tuning Discussion in N54
    Hey guys, moving the discussion to it's own thread, as it has the potential to be very beneficial :) Here's some data I have gathered, and a peek into some table data as well. As some of you know, the N54 as 3 different injections strategies, illustrated below: Mass Fuel Flow (MFF) into the cylinder is based off three things: fuel pressure, injector lift, and injector opening duration. Fuel Pressure: This is the HPFP rail pressure, essentially. It gets trickier due to the VCV (volume control valve) which is PWM controlled by the DME (may end up w/ a separate thread / topic for control of this). Skipping for now. Injector Lift: The DI injectors are Piezo. This means they have a stack of piezo crystals in them, which when energized, make the injection needle "lift" a certain amount. The amount of lift can vary, based on how much of the piezo stack is energized. From what I have seen, the N54 only uses two variations here, a low energy mode, and a high energy mode. I believe it uses these modes correctly already, so there is probably not much to be gained here. Injector Duration: The SOI / EOI (start / end of injection) is based on °KW, which is the German abbrev for degrees of crank rotation. They treat the full combustion cycle as 720°. To start this off, and keep it as simple as possible for now, I'll stick with single injection mode. Therefore injector duration calculation will be determined by 2 of 3 tables: Start of Injection #1 , then either the low energy or high energy opening duration pressure compensation table. The values for these can be seen below: Units for Start of Injection are X: RPM, Y: MFF (Load?), Z: °CRK Units for Injection Durations (low/high): X: mg/stk, Y: MPa (rail pressure?), Z: ms Do these values seem logical? The SOI seems reasonable to me. The only thing I'm questioning is the injection duration last two columns. Discuss!

    Finally got it all running and no leaks anywhere. Had a coolant leak since I have to fab that line myself, but all taken care of. Car seems fine so far. I've only run it in Map 1 (safety) until I can get some logs reviewed. I've attached them if anyone wants to take a look. Only odd thing so far is it's almost hitting 15PSI, and I have white+green (11 PSI) springs in the wastegates. Not sure what's up with that...

    Hey guys, CARB is requiring us to test some of our products on a 2012 335is so we figured why not pickup another DCT model to further enhance JB4 development on that front. This is our 4th active DCT development car but first with the N54 platform. Our 2015 M3, 2015 M5, and 2011 135i are also DCT equipped vehicles. We've got some fun stuff planned for the car too after emissions testing is complete.

    Hi all, sorry for my first post being a cry for help! Car is a 2007 N54 135i, I've slowly been adding parts as listed to take advantage of the Cobb AP v3 that I have fitted. VSRF catless downpipes Forge Intercooler Forge DVs ( I suspected the stock ones to be faulty) Running 1+ agressive running 99ron fuel in the UK (93 octane equivalent I believe) The problem is that I'm getting some odd throttle behaviour, especially evident if rolling on the throttle to anything that isn't WOT. I'm getting a major surge, boost overshoot and the throttle is opening 100% briefly. Seems ok if I snap the throttle to 100% and hold at WOT for a full gear pull, I guess the surge is being masked by the fact I am actually asking for 100% throttle? I would include logs but apparently need 5 rep to be able to, just as soon as I have that then :P I appreciate any insight you chaps may have

    Hi thanks for the welcome. Love my 335i, had it for nearly two years now. So far have vrsf downpipes, tial charge pipe, mishimoto intercooler, bms dual cones, jb4 g5 and the exhaust pe mod. Looking to maybe get the stage 1 turbo dynamics hybrid upgrade. Any one here have any experience with them? Thanks in advance.

    Just wanted to give a little feedback on it. Went in with high hopes due to the really good properties of the oil. I was hoping it would be good on my ST setup. Unfortunately there is a TON of valve chatter. Even with the engine cover and cowl back on the car. I'll probably end up swapping it for something else. Any recommendations for a high zinc, good oil to run in a ST setup that doesn't make the car sound like the valves are coming out of the head? :o

    Have spoke to a couple people regarding this. Meth is awesome for iat cooling, but port fuel injection is the best for distribution of extra fuel to cylinders when required for higher power output. In the sticky on n54tech regarding port fuel, its stated that if using both together, a smaller methanol injector like a cm3 or cm5 would be required. Anybody try this or used it? According to Terry, there have been plenty of people out there who have run both at the same time. Just wondering how it has worked and if any issues have arisen.

    I prefaced this as urgent because I have a dyno session today and I want to get this cleared up. The other day I made my first logged pull after installing filling up with 93/E85 after my inlet install. I have not gauged the E85 purity in a while so I am hoping that this is just due to a lack of octane. If the E85 was true at 85% I should be at E60. If the E85 was at 70% (which I am now assuming), I should be at E49. This is Map7 E85 BEF. It looks like octane deficiency to me for the . I would be happy to go stick 3.2 gallons in to make it E60 if that is the case. The two timing drops are probably due to lack of octane, right?

    Things have changed a bit regarding rally racing spectators. Why? Well, take a look at the gif posted below and you will understand why. Back in the legendary 80's Group B days as well as other rally classes drivers would have to contend not only with the elements but spectators as well. This speaks for itself.

    To replace the OFH gasket, the 3rd bolt that has to come out is underneath the intake manifold, which is supposed to be removed first. I know with the N52 you don't need to. My mechanic (really experienced porsche/bmw old dude) claimed he could remove that bolt without taking off the manifold. Is it possible??? And if so, how? (he wouldn't tell me haha) Really don't want to take off the manifold, but always willing to buy more tools if it saves me time.

    been trying to get a list of e92 M3 suspension parts that can go on an e92 335i. there seems to be alot of different opinions online. i have access to a m3 complete front and rear subframe (including arms, hubs, discs, lsd (3.15), brakes, ARB etc) for <$2000 which i currently think its more value for money than getting an aftermarket LSD. i know i will have to cut the drive shaft, weld and balance it. i have been told that i shouldnt use the M3 brakes due to differences in the Pump, does that mean i will have to use the 335i hubs? has anyone done this before, would appreciate some advice/information im running 500bhp+ and really need to up the handling, do i really need the complete subframes? it may be cheaper for me to get the parts separately, so if anyone has done this before and could send me a list of parts needed, it would help me get my head around what i need. thanks

    Hi guys, thanks for taking the time to read this. I was just wondering what you guys value when looking for someone to build/work on your cars in terms of tuning/customization and how much weight you put on each aspect? For example, my list in order of importance: 1) Community reputation 2) Customer service 3) Results (1/4 mile, 1/2 mile, etc) 4) Value / price 5) Experience 6) Objectivity (Don't try to sell you parts you don't need or are sub-optimal) I'd really like to see how my list compares with you guys as a lot of you have been tuning cars a lot longer than I have, and have a lot more experience. Thanks!

    This is some hardware you do not see very often on the drag strip. These cars are more at home on the roadcourse but they certainly put up a good showing in a straightline as well. The hybrid Porsche 918 Spyder is well known with its naturally aspirated 608 horsepower 4.6 liter V8 that revs to 9150 rpm augmented by two electric motors for a total system output of 887 horsepower. Unlike the other two modern hybrid supercars the 918 Spyder sends power to all four wheels. That means the electric torque helps it get off the line quickly and it puts the power down effectively. How quickly does it move? Well, it makes a McLaren 650S look like it is standing still. The 650S is no slouch by the way capable of running low 10's at high 130's in the 1/4 mile thanks to its low curb weight and efficient rear wheel drive layout powered by a 3.8 liter twin turbo V8. The 918 Spyder gets the better launch with a 1.64 60 foot to the 650S Spyder's 1.88. The end result is the 918 running 9.835 @ 144.95 to the Mclaren's 10.912 @ 133.46. The video claims the best time for the McLaren was a 10.3 @ 137.5 from earlier in the day but no proof is posted. It certainly is believable and well within reason. It also means the Ferrari 488 GTB should be a good match for it. Great runs and a well done video with multiple camera angles.

Occasionally smoke from under bonnet when running once again smell fuel. I recently changed the spark plugs and it has happened since then? Would that be the case?? Another thing that might help you guy is that the undertrays are of atm however I will be putting it back on tomorrow could that be a reason?? Any advice would be great . Thanks

    Anyone know where the transmission tag is located on our cars? I'm ordering new solenoids and the seller needs the 10 digit code that is located on the tag. They said it usually starts with 1071 or 1068. I looked last weekend when I was determining if I had a 6HP21 or 19, but I didn't see any tag. They need this number in addition to knowing that it's a 6HP21. I have no idea why...
