Curious about HP loss through the drivetrain.

I'll go and get another dyno and do a run down just to see what it calculates.

Make a call to your dyno shop and see if they can do that. When you make that, if you don't mind, ask them how they would do it with an automatic transmission.

Please.

Sometimes I wonder about the total fixation on maximum HP output. At our local auto cross, the perpetually dominant Boxster is a 2.7L bone stock (other than an IMS Solution) 986 with a five speed. He regularly hammers highly modified cars with seeming ease. It ain't always about horsepower............

That's probably due to him having his chassis dialed in perfectly.

Amen to that! I'm currently hunting down a couple of Z06 Vettes.

I like the sound of that, but you're not stock in engine or body weight department. Do you have the ROW M030 suspension?

EDIT: Just looked at your garage. You have K-sport adjustable coilovers listed. Is that what you're still running?

Yup, 7 years on and I'm still on the KSports. Waaay over sprung with all of the weight loss now.

I think you'd have to contact one of the dyno manufacturers like Dynojet, Dyno Dynamics or Maha. There will be an algorithm/formula in the software which will allow user input of a restricted amount of input parameters.
