Could it not happen say tuning a car from 8lbs to 30lbs. Car has been ran a lot with minimal cool down time. Intercooler is too small for the boost pressure / flow / compressor outlet temps. Quoting Tony Palo (T1). Though this might not be the case with Dave. I dont know. It's about the cross sectional area available for hot flow (height x depth). That's where pressure drop happens. I hate to use the straw analogy, but try to shove 85lbs/min of air though a straw. You can only fit so much efficiently, so you end up with more pressure at the inlet side than what makes it though the "ic" and you now have pressure drop. When you use an intercooler way past what it was designed for, it's not only the temperature increase, it's the pressure drop that you get. That's why it's always better to go taller and thicker on a core, not longer. You don't want to go too thick either, or you risk not getting enough air flow through the core, for cooling. This would explain the ait's being a little high and the pressure drop we were getting

If you reread what was typed, you will see that was was stated makes absolutely NO SENSE. Trust me and reread the sentence.
I just dont understand why people can not believe this. First let me start out by saying I have 0 Buschur parts on my car. I have never purchased anything from them. Me for example. I am running about 26 psi on 93 octane on the stock ecu. Its all about the tune. I will gladly post logs of my car without my timing or AFRs. I have no knock at all. Just a random 1 in 1 or 2 spots but never the same spot in multiple logs.
Alpha, I think that we are talking about two completely different things. You are bringing up intercooling theory. Even though many points you make are quite textbook in nature, the post I was referencing has to do with terminology and accuracy.

Its not always about boost pressure. Way too many things are being overlooked in this thread. Boost Pressure is a mere formality at this point.
Pump gas numbers of this sort actually are believable...its just that this is another thread about ONE specific car that magically can not detonate because it has BR all over it.
The amount of cylinder pressure needed to develop this kind of high rpm output is astounding for a 2.0l engine. My question is what RPM is this engine being revved to?

There is a big difference between, 26psi and say 400- 450HP and 525+ at 28psi on a GT35r and pump gas.

i will post up the dyno sheet, in a bit. RPM was to 7500 when it made 525, and it was still climbing. I shift at 7800-8000 at the track.
