Here's another one.....
572 Indy motor......made 920 on the engine dyno, 778 rwhp on the chassis dyno(glide with a 5600 converter).
Car went 8.33@165 at 2700lbs.
How do those numbers work out?
You're correct. Guess I have been operating under a misconception for a long time!
Just for sh*ts and giggles, I plugged both FW and RWHP numbers into the Wallace Racing 1/4 mile stats calculator which I believe is based off the Moroso slide rule.
With 920 HP @ 2,700 lbs it spit out 8.34 @ 162.05. Pretty close.
With 778 HP @ 2,700 lbs it says 8.82 @ 153.24.
Guess I could have a 10 second car after all. Plugging my 500/3,200lb numbers in to the weight/HP calc. says 10.81. If you use the 3rd calculator down which is ET/weight it says 10.50 @ 3200 = 546 HP.
