RWHP to Crank HP reduction

[69znc]

hp2 - yes I have "heard" many things but the point is not "heard" but empirical data. This I can believe in with many points of verification. Thus my post. No it does not matter the crowd you hang with if they are serious.



the dyno does matter thus the need for some structure in testing.

Ron you still have the most factual opinion with empirical data and test time.

Again I think for our cars featured here lose of low 20% is great!

69znc & hp2 ...

I think we're saying the same things ... 20% loss in a street car is to be expected ... give or take a little ... depending on auto or manual transmission & a few variables.

I think the newer cars in the last 10-15 years have accessories that draw less power & more efficient drivetrains. I suspect if we compared a newer Camaro, Mustang, Challenger or Corvette, we would see numbers under 20%.

Just my 2 cents.

Thanks for the great insight Ron.

I guess I didn't get my point across adequetly. IMO, the guys with a fist full of timeslips or a log book of info have empirical data. These guys tend to speak from data driven results. Liek you said, these are the people who are serious about their performance and how to improve it.

The guy who swears his 396 Chevelle with dual quads put down 500 horses because it would burn rubber in all four gears is at the other end of the spectrum. In my experience, these two groups typically only tolerate each other for about 90 seconds at a time before hostilities begin. They don't hang together very often, so association with one group will never get you data. Association with the others will get you as much info as you are willing to digest.
