I drag raced for years and spent lots of time around chassis dyno's as well. As an example there is a thread on Pirate where one of the Ultra 4 guys posted up his flywheel numbers and at the tires. Both verified on a dyno. Difference for him was 37%. Top of the last page of this build thread.

The engine in my buggy is a 406 with Brodix heads, Holley Stealth Ram injection and a fairly large flat tappet cam. It better have more than 325 hp or something is seriously wrong. You'ed be surprised how much power all this heavy weight drivetrain sucks up. Wanna race?
