i ran 11 psi through a 5.0 liter air/air intercooled American V8 with EFI back in the day. It was a blast and I never blew the motor, even after putting 40k on it.. and it had a 9.5:1 ratio. That being said; it was a bolt-on kit. It took almost a month to hammer all the kinks out (literally and figuratively). If you're not a pro, this is not something to embark on. You can hand your car off to a pro and pay the full price and run moderate boost.... or you can build a bigger, better motor. Or you can rebuild with lower compression and run high boost. But no matter what, it's not going to be under$ 10k on a Porsche...
