DIN vs SAE Hp?
Brent,
while you are inquiring for hp values most engines on your side are still rated SAE, aren't they?
Example: my 496cui had 500Hp at the wheels, translating in 565Hp DIN at the flywheel with 12% losses in the drivetrain (in 4th, "direct" gear).
An US calculation resulted in 700Hp due to 20% losses and 80Hp for auxillary components and inefficient exhaust (assumed losses for exhaust).
700-80=620Hp
620x0,8=496Hp
With BfG the wheels were spinning endlessly in the 1/4-mile, with Hoosier AutoCrosser I was okay (in 2000). The cam was very torquey 0.560 lift mech roller, but using 1.8 ratio (Chev BB). The springs I had allowed for only 0.600" lift.
In a nutshell, you rely on rear wheel hp (rwhp) for your assessment?
