this gets brought up once a day.

the answer is 10 psi, 12 psi if you're feeling gutsy (and you have a front mount)

you should be fine with 550 primaries and 720 secondaries. you need something to control them with though...

12 PSI is about the limit when you've done the basic fuel upgrades. After that, intake temps skyrocket. 14 PSI on the stock cooler and you'll be seeing 150 degrees...
