Do any of you ever record coast down BHP numbers? I know that the Cup and short track guys do to see the friction reductions in changing trans and drive line equip. This comes from a short track team going from 283 WHP to 299 WHP only working with trans seals, diff. seals, low friction diff. bearings, rear axel seals, etc. Coast @ 100mph in std. trim was 25 HP coast @ 100 MPH with the modified stuff was 10.45 HP. This was on a Dynojet 248. Also in adding up the numbers I wonder if this was a 310 BHP engine, the guys doing the test did not know.

 

Guess it was a dumb question. Drive line friction means squat.

 

When I was in Miami I wanted to try and measure this, but my boss thought it was dumb and wouldn't let me use the dyno (also a Dynojet 248) to do it. I had an open diff B16 tranny, an OEM viscous LSD B16 tranny, and a CTR tranny I wanted to compare.

 

I have found a Honda guy that will try to get some numbers on their chassis dyno.

 

whatchu talking bout willis?

 

Some guy in Atlanta that actually wants to learn something. You are the likley suspect.

 

An interesting idea. It would be nice to truly have some hard data on this for once.
