How deep are your buddy's pockets and how long does he want these motors to last?
Safe way is to start 4-5psi and adjust up from there. If he is a balls to the wall guy that always has to be fastest I doubt he will take that approach though. Also if his drives are Bravos that is another consideration, its always nice to have reliability

Not getting into any debates but here is my opinion.
The 8-71's at -15% won't make any real heat to warrant chilling and losing idle quality. If it had a 256 blower with a higher rotor speed I would say chill it. BTW, what kind of boat are we dropping them in?
Is this a weekend pleasure boat, Jet or I/O?
Also what size heads?

And yes, the injectors are on top of the blower.
PS, as to the original question, I run 7psi but only 8.2 SCR.
