I would say 410-420rwhp on motor depending on the head flow.

i'm going to pick on you, but it's not personal, and it's without malintent.

this is a generally flawed approach to building an engine. you should first set your requirements, then research what it takes to meet those requirements. what were you looking for in numbers? durability? streetability?

also, final boost numbers are relatively meaningless. to answer the question, one would need a very good overall feel for how much flow equates to 12psi through your heads/cam/intake/cid combination.

pre-blower, i'd say you're looking at 360rwhp. however, this is also partly based on my conception of ARE's work, not just the hard parts you mention.

Thanks MSR for your response to my post ,but I purchased my D1 before I had the engine built . I disscussed with Wade at ARE as to what my goals were which is 550-600 rwhp, thats on boost of course.I was just curios as to what I would have to play with until I've put enought miles on it to add the blower. :cool:
