85psi could be made but the drive pressure at that point would negate any peak power gains.

The marine injectors are going to hold it back on ya. Egt will be higher then it would be with the correct nozzles. But 500 hp should be easy enough.

Yeah, but my limiting factor at this point will be the injectors and clutch, wich is fine because i don't have the fundings for a new clutch atm...

But with studs and a marine head gasket i should be safe for all that boost?

When should i be worried about having to ring the head ?

Keep it under 80 psi drive pressure without rings

Would you recommend a set of four or should i run these 33x14,5 at the rear ?



Anyone want to put down a bet on 1/4mile times?

the 370's can get you pretty far, if your dead set on them raise the pop press and keep your timing in check.

That will be a great setup with proper fuel can make 700 hp, which hx60 is it? I believe there is a 74mm and an 80mm wheel for them
