wow.. very nice and congrats! question about the base run, was the base run with 98oct as well?

Post #65. On a dyno dynamics dynomometer, reads less than a dynojet.
Shiv, its a rolling dyno, the rpms dont match because we didnt tap under the hood, we tried to match revs on the dyno, none the less you get the point.

I see a peak around 5700-5900 rpms on that dyno? Isn't that what Shiv said the peak on this engine would be (around 6000 rpms)?
And since the tach wasn't hooked up on your dyno, can you (or us) ever know where the power peak really was?

So as more air is forced through this smaller turbo, how does the boost fall off? Is it that the air flow becomes turbulent because it is beyond its efficiency?

Edit: Kind of funny how people jump on the bandwagon and start to bash? I am just trying to weed my way through garbage and real knowledge, but I have a great deal of difficulty figuring out who really knows what they are talking about on here sometimes.

No the compressor wheels just arent designed to handle airflow past a certain rating...Shiv has turned up boost beyond max potential, and those turbos shouldnt last much longer gettting beaten on everyday like that.

Id rather start throwing better parts at the car than turn it into a hand grenade.

I like how people keep throwing out the phrase the "engine/turbo is gonna blow" yet it hasn't happend lol...

[vase330]

Well, if no one tells, how would you know? All we know so far is that there are a lot of unknowns...

Yeah, and I'm sure Shiv, by far, has the most abused miles on a 335i.
He's got what, over 30K miles on his car...almost ALL of which heavy, hard test driven type miles on it from him, magazines testers, and customers!
His car probably has more abuse on it than most cars would receive in 150k miles from the average car enthusiast, and more abuse than 300K miles from a "normal" car owner.

I know I myself have 36k miles on the clock and I haven't had major issues related to Procede.

Nice numbers!

Did you know that AA blew a turbo pushing the limits of this car?? See AA will issue imformation but Vishnu keeps pretty quiet compared to them. Do you notice that Vishnu is the only Tuner willing to take it to that level, there are alot of other Tuners that have been establish for a longer time believe that 400 RWHP is too much for a daily driver (AA, ICSPERFORMANCE)..............


I just need more proof then 5 weeks and i am betting he isn't running that 100 octane on a daily basis also!!!

[revah2]

30k miles is virtually nothing. Enough with the turbos is gonna blow stuff... expect your turbos life to be a lot shorter if your car is modded. Period.

Is it the increased heat or just the simple fact that they're spinning more?

Wish I could answer you . I'm no technician but it is fairly obvious that the more strain you put on a turbo- whether its increased heat/pressure or the turbos are spinning more- they are going to have a shortened lifespan.

So you're basically implying that Vishnu has blown an engine with a procede, or they know of someone who has, and they haven't disclosed it?

They could go at 300,000 mi instead of 500,000 mi? I had to replace a set of turbos on another car at 80,000 because the flanges started cracking due to heat (I would often see them glowing bright red). However, these BMW/Mitsubishi are specially made: "A special austenitic steel with a high proportion of nickel is used to accommodate the high exhaust temperatures in the turbochargers, according to Udo Lindner, BMW Project Leader, 3 Series Powertrain. The steel, used in the spinning wheel, can accommodate temperatures up to 1050˚C (1920˚F). Lindner noted that BMW worked with Mitsubishi Heavy Industries to develop the turbochargers."

So they're probably more robust that most, although I don't know what the common heat tolerances are.

Why does everyone say blow an engine, THE TURBOS will go before the engine goes. I wouldn't doubt the possibility of Vishnu blowing a turbo, especially with AA in their R&D having blown one............


Most of the time in R&D a company will not release bad information, majority reason is because its just bad publicity for their product and promoting their product as a possibly dangerous one...............

Look at it like this, he said he has been running the car for ONLY 5 weeks this way, that is NOT a long time for R&D reasons..........also I am pretty sure he hasn't been running 100 octane 24/7, 7 days a week for 5 weeks, so my guess the car wasn't at the peak stress for all of those hours..............give it at least 6 months before possible problems arise with 400+rwhp (not 5 weeks)

Was not aware of any of that. Thanks for that tech. tidbit.

Seems BMW went above and beyond to ensure longevity on their first mass produced gas turbo engine since the 2002.

im sure they will last to a certain degree but trying to imply that these turbos will have a life anywhere near what they would normally have is ludicrous....impressive work nonetheless, and very appealing, but you're producing almost 60% more horsepower than what it came with from the factory......easy to forget the research and work that was put into developing these turbos and their specs......more work than any tuner ever will

+1. No flaming intended, just curious to read what AA stated as far as blowing a turbo goes. I never saw it.

Im not searching for the thread they posted it in vaguely..........PM them, they will gladly tell you, ask them questions about the limits they believe the turbos have on the 335i................they are pretty helpful, or go to ICSPERFORMANCE.com and get their phone number and talk to brian...........they I THINK are trying to create a FLASH for this car, that can be a CUSTOM TUNE, because the guy they are working with in Europe breaks all of the BMW ECU's..............talk to the professionals, obviously Vishnu is not available

They're dedicated to this new format: direct injection + turbo charging. If you read the news, it appears that almost the entire auto industry is headed down the same path.
