    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!

    Many of you are wondering why someone would ditch the S62 5.0 liter V8 under the hood of the E39 M5 for a smaller BMW inline-6 motor. Well, these results make a strong argument for such a swap. This E39 M5 belongs to BimmerBoost member @Omni. You can read all about his decision to do the swap in a past article. Even at lower power levels than the car runs currently it was a beast. @Omni beat up on a tuned Cadillac CTS-V Wagon as well as a tuned F13 M6 Gran Coupe. With the car now making over 800 to the wheels it is safe to say he can take on even more stout competition. He is running a Precision 6266 turbocharger at 35 psi of boost. 100% methanol is injected in a direct port setup. A water and methanol blend is utilized as well before the compressor. Tuning is by @NickG of Technique Tuning and done on the stock DME no less. The result? 813 horsepower and 819 lb-ft of torque at the wheels which works out to comfortably over 900 at the crank. However you feel 800+ horsepower at the wheels is serious power and this may be the world's most powerful E39 at this point. Simply incredible results and props to @Omni for continuing to push the boundaries.

    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...

    This is getting ridiculous. We were already blown away by the Gen V Viper making quadruple digit horsepower on the stock motor this early on in its tuning. A tuner by the name of Unleashed Tuning managed to hit 1002 horsepower to the wheels on 93 octane. Calvo Motorsports has taken things quite a bit further on 93 octane pump gas with 1187 rear wheel horsepower and 1175 lb-ft of torque at the wheels. What allows this kind of pump gas power? It is tuned on a Motec M1 standalone ECU. Calvo's tuner believes they could easily get it over 1200 whp on pump as well but they think they are pushing the motor far enough as is. No knock, no detonation, and no issues with almost 1200 whp on 93 octane pump fuel. The scary thing is it can go further but nobody wants to be the first one to find the limit of the Gen V Viper internals. What can you say? The new Viper is badass.

    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

    Congrats to AudiBoost member @spool twice who improved his 11.881 @ 115.93 1/4 mile run in his B8.5 Audi S5 to 11.652 @ 117.81. This is the quickest B8.5 Audi S5 time to date. What makes it impressive is this is still on the stock blower with no weight reduction as well as with Dunlop street tires. Mod list: - GIAC stage II v2 Race - GIAC TCU 4,000 rpm launch control - AFE filter - 034 Throttle Body Boot - Drilled hole in airbox - x-pipe mod - E85/93 octane mix - AWE-Tuning pulley Track density altitude at the time of the run was 567 feet. That means there is probably a more in it. Maybe a mid 11 at roughly 119 miles per hour? Definitely quick but there is not much more left to get out of the OEM blower. It will be interesting to see if he takes it further.

    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

    We know the turbocharged 488 GTB should be much faster than the naturally aspirated 458 Italia it replaces. Especially in the 1/4 mile considering the Ferrari now has turbo torque to get it off the line quickly. EKanooRacing took what they say is a stock 488 GTB to the Bahrain dragstrip and here is the result. On a 1.706 60 foot time they managed a 10.372 @ 137.35 miles per hour. That is a very impressive run but this sort of performance should put the 488 GTB roughly even with the 650S from McLaren. So why did we see a 488 GTB lose from a roll to a McLaren MP4-12C which is less powerful than the 650S? Was that 488 GTB a dud? Was the MP4-12C tuned? Is EKanooRacing using race gas? Is the Bahrain dragstrip accurate? All valid questions. We will need to some runs on NHRA certified US strips to put this result in context.

    A couple nice runs here from a BMS JB4 tuned F10 BMW M5. The car is running a 50/50 blend of meth injection on 93 octane. It also features MSR intakes and R888 tires for traction. The Mustang GT Coyote V8 is blown with a Kenne Bell twin screw at 12 psi on E85. The M5 and Mustang go at it twice. The first run has the Coyote pulling decisively. In the second run the M5 takes the hit and holds off the Mustang GT. They each get a win which is great but it should have been settled with a decisive third race. Maybe we'll see a rematch? The Mustang gets a bonus run with a Paxton supercharged Gen II Dodge Viper at 6 psi of boost. The V10 is also stated to be stroked. The Coyote pulls it impressively so the Viper might want to run more boost next time. A run between the Viper and M5 would be fun to see as well.

    A couple races between some local cars. F10 M5 with MSR inlets, JB4 and 50/50 meth. 93 oct and 40 add, on R888. Coyote is a Kenne Bell car with Mammoth return fuel system, e85 and drag radials. Coyote is rumored to be around 700ish HP. https://youtu.be/oGpMF8ixqOA

    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.

    This should not be a shocker as Hennessey often takes credit for the work of others. Don't believe it? Hennessey patted himself on the back for his HPE700 Mustang GT supercharger system when it is really Whipple's blower and design. Just like how the Hennessey HPE600 AMG GT S tune is really Eurocharged's tune. Jerry Thorton at Eurocharged did the custom dyno tune. Hennessey will essentially resell the $2499 Eurocharged M178 tune at a premium. Why bother with paying for the Hennessey name when you can go straight to the source? Anyone?

    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?

    Congratulations to BenzBoost member @charliekay who is so close to the 9's in his supercharged W204 C63 AMG that he can taste it. He upgraded to the Weistec 3.0 liter Stage III twin screw blower and ran 10.22 @ 137.09 which was a considerable improvement from the 10.83 @ 129.22 he managed on the Stage II 2.3 liter blower. Now with different wheels and tires he shaved it down to 10.173 @ 139.18 on a 1.549 60 foot. Obviously a better launch than the previous 1.606 60 foot so the new tire setup is helping. He is just a hair away from the 9's but as @charliekay is an Australian member keep in mind the weather is not doing him any favors right now. In the winter we might see that elusive 9 second pass which is certainly impressive for a stock internal supercharged M156.

    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.

    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.

    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.

    This race is a mismatch in stock form let alone when tuned. That is why the result is somewhat surprising. A tuned AMG GT S should easily pull and this tuned example does indeed win. The Jaguar F-Type R puts up a good fight though and it is closer than one would expect. The F-Type R utilizes a supercharged and direct injected 5.0 liter V8. With 550 crank horsepower and 502 lb-ft of torque it is no slouch. It runs high 11's in the 1/4 mile at roughly 122 miles per hour. Solid numbers. A stock AMG GT S is faster though. Comparison tests of the AMG GT S and F-Type R coupe already tell us that. The AMG GT S runs low 11's at around 127 miles per hour in the 1/4 mile. It already has five miles per hour on the Jaguar at the 1/4 mile mark stock. Keep in mind the AMG GT S is 400 pounds lighter, has a quicker shifting dual clutch transmission, has a higher redline, and its twin turbo M178 V8 is underrated in stock form. The race in the video is much longer which should favor an even greater trap speed disparity but the HG Motorsports tuned AMG GT S only managed four miles per hour on the Jaguar. Why so little? Why only an advantage that a stock car should easily manage or even surpass? We heard rumors of a Weistec tuned AMG GT S demolishing this HG Motorsports AMG GT S at an event so it is possible the HG Motorsports tune needs work. We do not know if that is the case but we do know the AMG GT S clearly wins this race.
