Street driven? Cog or serpentine? How many miles did you drive with that setup?

I'm not asking blower vs turbo. I want to know the biggest Procharger I can turn with a stock double keyed crank.

We have done 2 cars, one stock everything with cam, auto f1 did 570 at 7 psi corrected went 11.3s all day at bandimere, got beat on daily and still going.

The second car was an f1a stock crank but forged motor did 14 psi and close to 800 corrected, still running no issues and the owner likes to run it hard and does almost daily 140+ pulls on the highway.

Both with keyed cranks.
