Approximate HP estimate?

[TurbododgePirate]

Stock 1991 Spirit RT + 3" exhaust with cat and muffler. 12 psi boost. ANy idea approximate hp? I remember that they were dynoed at 250hp after a 3" exhaust was added, but I am just wondering about the 12 psi boost.

Thanks~~Heath

210-220. Factory boost was 11 psi, so you're only 1 psi higher than stock. The exhaust will free up a few. Bone stock, I've seen/heard of more than a few R/T's that put down about 190 at the wheels.

Seems that T-III HP is all over the place stock to what you have.

I've seen a T-III IROC R/T with adjustable cam gears, exhaust (not sure of the size) and right around stock boost make around 190whp, then at the same dyno event, a bone stock Spirit R/T with only the addition of a muffler made 220+whp on a verified 11psi of boost.

I haven't played with my T-III's yet, but I do know that degreeing the cams on a dohc engine goes a long way.

Will Martin put down 217 on a stock setup with a rebuilt engine. Not bad, :amen: :D
