[Cobra #42]

Guys, If your are really interested, and your dyno guy is sharp and will take the time, he can do a reverse dyno run and by measuring the coast down time and give you your exact loss numbers. But for most dyno operators that have done 1000's of pulls , they use the 16% number unless you have micro polished your ring gear and pinion, also same process to the trans. Use your dyno time with an O2 sensor and get it dialed in. 369 RWHP will kick alot of 500+ HP ass, that has never been on a dyno !!!! everytime

What I like to see is all the 500+ HP Bull Sh...ters walk the walk and get on a dyno or just talk the talk.
