About 900 I Would Guess Maybe More With A Blower Or Turbo And Some Headers Should Add Another 200 Or More Horsies I Think But Then I Don't Have a Dyno But Just A Slanted Way Of Looking At Things That Are Difficult For me To Read Or Understand Without My Mind Reading Glasses On Because I Left Them At My Shrinks Office When I Made A House Call To Help Him Be Rid Of Some Black Ants We Think Are Mind Eating Termites Should We Use Mustard Gas Or Malathion.

The guys are having fun with you at your expense.

You need to list everything that was used in the engine - cam, intake , carb, compression ratio, piston type, head flow #'s, deck clearance, rocker arm type and ratio, header size, what accessories, carb size, cam installed position(advanced or retard or 0) etc. EVERYTHING!! :)

And even then, w/o knowing what your tuning abilities are, the estimate may or may not reflect what you actually have. At best, it will be a rough estimate of the potential power your engine has.

The sim programs typically estimate to the high side of real world dynos- which themselves (dynos, I mean) vary between the dyno units, operating condition, operators themselves, whether or not a correction factor is used- and which correction factor is used, etc.

Better horsepower, but the torque improvement is reason enough for the change.
