Max cyln pressure on pump gas ?

Was still going off of this OP.

That was strictly posting a question whether or not it was possible. I was not stating you could do it. Just a question. I personally wouldn't feel comfortable with pump gas at that CR. Although I know a guy who ran pump gas in his 14:1 440 challenger to drive it to a show because he had no race fuel. He mixes pump gas and 110 race fuel to run the car. Do I agree with running the mix? No. Pump fuel, that was dumb imo. He ran the mix workout pinging. On pump gas it would ping if he gave it much throttle. So he said.
