Once I tried doing a burnout in the waterbox, but it shorted out my keyboard!

Car A: 260hp x 5252 / 240ft-lb = 5690rpm
Car B: 240hp x 5252 / 260ft-lb = 4850rpm
He said gearing is the same, so Car A is going 17% faster.

He beat you to the stripe with less HP. I'd call that a win every day of the week! You wouldn't brag about having the highest golf score and the most expensive clubs would you?

If you're behind me, going slower, but accelerating more than me, I will still be pulling away from you! Think about that one.

Whenever I go magazine racing, I always prep my hands with VHT. This keeps the pages from slipping and giving me papercuts. Racing is dangerous, you can never be too safe.

...with the information given how to you get to comparative data at the same speed, maybe make some assumptions???

OK, as OP, I'll mention the specifics that I have in mind:stock, L98 Vette vs 07/08 Toyota Camry. On a more big picture note, reflecting on the HP wars- such that many current sedans have more HP than sports cars of not that long ago
Back to Camry- yeah I know, 200# or so heavier than Vette, but think of heavyset owner (w. SO as pax), being offset by 98# grandma in Camry potentially matching up against L98 Vette
at certain speeds. For number crunchers, V6 Camry gets 268 HP @ 6200 RPM, 248ft# torque @ 4700 RPM. For other sedans,(latest Taurus, Sonata, etc, numbers quite similar). None can match Vettes torque, or aerodynamics @ speed. Just for the record- I'm former 92 coupe owner, current C6 coupe owner, and at least casually interested in automotive history/development trends

We'll have to get RED85Z51 in here for that one. He is our resident Camry racing expert. He has seen the taillights of many Camrys.

Either way, we race IHRA up here and it's all about dial in w/ handicaps.

What would be useable formula for calculating effect on acceleration for any given HP/Torque.
My specific example: Car A & Car B making acceleration run, identical in every respect (weight, axle ratio, gear ratios), EXCEPT, that Car A, at given moment is putting out 260HP, 240ft# torque, Car B is putting out 240HP, 260ft#torque. Would both cars accelerate the same throughout the sprint, OR would superiority in 1 factor trump superiority in other factor? Thanks
