100? LOL!hard to think some have 100psi
Did you steal an oil pan and money from those guys too?100? LOL!
I don't know where they are at today since I'm not longer involved or keep up with it but, in '03 Super Stock was running in excess of 200psi. The one I was associated with was running 218psi at peak rpm. The head was an aftermarket casting but the blocks had to be stock. You're talking about a block that was originally built for 150 or so HP and we were making around 3000.
