Qtr mile or ENGINE dyno results

Got you,Cool, you had me worried, I thought I had at least a 1000 FW HP to be running the E.T. & MPH I run....LOL

I think the 17% figure, is most likely for stick cars.Auto's are in the low to mid 20's and I would think loose converter auto cars like mine are in the 28-30%...But I am not saying this is a formula by any means.

I use 20% on mine with a 3800 converter, 727 manualised trans and a 8&3/4

I have found that Moroso and my track times/mph agrees almost exactly with my Chassis HP + 20% losses ( / .80)
