I know you asked this of Eugen, but IMO you're always going to see a boost spike inside the intercooler tube when the throttle closes quickly under boost. It won't likely be as high as some have seen since the stock, but you'll see a spike of some sort before the diverter valves relieve the pressure (which is their job). The BMW documentation says the N54 operates at an overpressure of 0.8 Bar or 11.6 psi in the intake manifold. I think the spike is so short though that it wouldn't be so easy to catch it unless you were datalogging with a device/software with a resolution (sample rate) that fine.

BMW doesn't provide software for customers to datalog their car. Maybe they are on to something. It's too easy for people to misinterpret data and think that something is wrong with their car.

BTW, I was referring to this thread as being "ridiculous". Not a person. At worse, Eugen simply didn't agree with my conclusion based upon the data he recorded and jumped to what I believe is an incorrect conclusion. This data was posted in this thread. Others can make their own conclusions about it. I will honor his wishes not to disclose our email correspondence. Although i think doing so would shed a lot of light on the incidences that led up to this ridiculous (there, i said it again!) thread.

I'd be more than happy to help them out because this blown motor nonsense has to stop.

You don't see any customers with blown motors because it never happened. Everyone knows this is the FIRST place someone would post about a blown engine. People paying attention to the topic of blown motors know that it's never the actual person reporting it - it's always "I heard a rumor" or "a friend of mine heard" or "my buddy's motor blew up". Then once the flames and posts die down, you realize that person never posted a followup. Every one of those posts is complete

If anyone is going to blow an engine or tranny in the 335i, it's going to be Vishnu, in development, which is the whole purpose of endurance racing and testing. I seriously doubt if there are ANY N54 engines out there which have been thrashed anywhere near as hard as Vishnu's.

Hi Shiv,

I tried to accelerate from 2800-3000rpm again and again and again and finally I could reproduce and document exactly the issue. It has not been normal. You should investigate, you probably will not get better data.

Completely OT (Like half this thread), but every time I hear about someone's buddy or friend I always think of this.

Dark Helmet: Before you die there is something you should know about us, Lone Star.
Lone Starr: What?
Dark Helmet: I am your father's brother's nephew's cousin's former roommate.
Lone Starr: What's that make us?
Dark Helmet: Absolutely nothing! Which is what you are about to become.

completely agree with you, I understand they are under an agreement, which can get you into legal problems if broken. I'm just saying I agree with what he believed was right, which could possibly be done in other ways avoiding this "ridiculous thread".

Boost does not stop raising where it should. I tried the procedure 30-40 times and finally got it. There are postings on this forum describing this situation, the difference is that my car stopped at 13.2psi, other cars stop at higher boost levels. I do not recall who posted it, but there is a reason why I did the same test 30-40 times.
