I'm trying to figure how much boost I can get away with on 91 pump gas.. 496 BBC 8.0 to 1 Iron heads..
It's a jet and I know that should make a little difference. The blower is only making about 5psi right now. I'm running 30 degrees total advance. I set it at 32 on the dyno but wasn't gaining much power anymore with the last two degrees so I dropped it back to 30.
I have a boost retard but it's set to zero. The cam is a 114 and 288 duration so the cylinder pressure is probably pretty high even with the low compression..
If this were a turbo I would just keep turning it up and watch for sparkles on the plugs but buying pulleys isn't free.. lol
Big block chevy's are not my normal thing so any help would be greatly appreciated.
