Resto, I think your comments are right on target, not a thread drift at all.

Assuming Rawkkrawler has lost about 25% h.p. from flywheel to rear wheels he is right at one h.p. per cube. 25% loss maybe be a bit high, but within reason considering we don't know a lot about the specifics of sidepipe loss, drive train loss and accuracy of the dyno. Dyno numbers can sure be miss leading and are fraught with variables difficult to nail down. Could be as simple as what gear did you use to get the dyno reading in the first place? Some say third is better than 4th. Or, should you use 5th? Theres actually a math equation that arrives at the best gear selection for a particular setup, so there in no one single correct answer there.
