LMAO I ran 30 psi for 2 days when my mechanic was sure my boost gauge was like the one in the instrument cluster showing 2bar when only building 1bar. Here is a clip after i found out i just carfully build boost up to 1.8bar 26.10684 PSI remeber this is a very old video and on PUMPGAS! The two days before was not the best for the car. The headgasket came off the car last weekend and my mechanic said it looked like new so i think the 944 turbo gasket is under rated at best. I also have to say that i have run to high boost pressures for the past summer with no other issues than EGT.

Well Sid and Steven / 'eniac' have run consistently high boost on E85 for some time. When I hit 30lbs it was only pretty briefly when a vacuum hose had come loose from memory. Damn the car felt pretty fine I must say!
To your point Sid, I wonder about that. As you say, pressure is pressure. In most of our cars there are all sorts of components that can lead to average V.E. / flow etc. In addition what seems to be the Achilles heel is the headgasket. This being a symptom not a cause, but with pressure comes headlift, open deck cylinders and vibration which damages the seal. I assume you are implying that a proper tune without detonation is allowing us to raise the stakes and E85 is the Jungle Juice of Love?![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

I think in a sustained track environment that window closes due to heat, etc.. but on a street car just having a good gasket along with orings run etc does very well.
I guess that coming from an alcohol background my opinion may be very much in reverse of those using gasoline. My example would be that I personally would never attempt to make any real horsepower on petrol. If it was the only choice of pump fuel I'd have a large tank for methanol. So to me, yes it is a blessing having e85 so readily available
