    thinking too much, here's why...to get your rear wheel horsepower those numbers take into account for your drivetrain loss (parasitic loss due to multiple moving parts and their mass in transferring the power from the engine to the pavement). so to be at that rwhp number that means you have to have more power at the source (engine)...

    so to figure out roughly your flywheel/crank HP you take your rwhp number and multiply that by 20% (or .2)...next you add that number back to your original rwhp numbers and there's your flywheel/crank ESTIMATED horsepower...

    you do the reverse math to figure out your estimated crank HP, since crank HP is not known while the engine is in the car, all accessories hooked up, and the drivetrain attached to the back of the flywheel...

    also dont let it slip the mind that there are different kinds of dynos, enigne dyno (enigne only when it's on a stand and hooked up to emissions components/no accessoires such as power steering/AC), car dyno (like what you had done, in the car, all accessories hooked up/attached), and others, etc...

    hope this helps clear some things up...

    This man knows what he's talking about. I understand easily because I work with numbers and formulas everyday. However, I couldn't have explained it any better.

    Your next mod should be a LS6 intake.
