Indicate the max boost you run on the street, regardless of what gas you use (pump, race, water/alky modifiers, etc).

I normally run abour 20psi. It doesnt really matter how much you run since you can keep your foot off the gas. I rarely get more then 10psi on the street anyways, any more then that is unneeded

about 16-17psi for streets, and hardly WOT. sometime i see 10psi then i let go

Before I decided to tear my crap down I had the wastegate actuator pulled off my e316g and saw 28psi sometimes creeping to 30psi. That was with 750's, Supra pump, and DSMLINK. The most CFM I think my motor ever saw was just under 30psi on my 20g on C16. I love to push for as much boost as I can, but it has caused some destruction on a few occasions. I guess I should pay attention to my knock sum a little better or at least not ignore it rofl.

I'm just now (picked up the motor yesterday) beginning a 6 bolt G4CS build, and am hoping to run some 1/2 decent boost on it. I'm actually going to be selling my 2G to finance the motor build and then sourcing a 1G AWD shell AFTER the motor is finished. That way I know I'll have as much $ (hopefully) as I need. With Eagle crank and built 8:5 internals/head it should do allright. The most boost I've ever witnessed was just under 80psi on a fully built Dodge Ram with a 12v Cummins in it. The guy had actually modified a compression tester to be his boost gauge!

Dont worry about the lack of self control thing... i have a track racing background.. and i have the same problem.

and does it improve your performance?
It's higher octane fuel - which allows you to run more timing advance and more boost without detonation.

But if you did a simple search, you could find out everything you need to know about "race gas"....
