Question on HP

[mcbride66coupe]

could you please explain to me what factors effect rear wheel hp versus flywheel hp? how much of a difference is there in fly wheel and rear wheel hp?

parasitic losses through the drivetrain is what makes the difference between FWHP and RWHP. generally i think the formula is something like 15-20% loss between FWHP and RWHP. for example a 300 FWHP motor would be putting approximately 240 hp to the ground.
