I just put in my numbers into the horsepower calculator and i got 2 very different numbers based on trap speed or et. I was told that the et calculation is based on a 60' or 2.1sec.

the trap speed one says i'm making 483rwhp. Is that even possible? 6140lbs race weight, 13.35@100.29mph

I need to get on the dyno at Dez soon to find out.

 

That sounds right. That a heavy-*** truck.

 

yup sound rite to me

 

Which calculator did you use, and where is it on the net? Seems to be pretty close but I'm using Flywheel calcs and having to figure out rwhp from there.

 

If you are spinning alot, use your trap speed it will be more accurate. Try this one Jimbob.

My 5.3 with 9lbs is making 413 so, I would say it is very possible with a 6.0 and 10lbs.

On a side note: the calc says I should run 14.05 @ 97mph, Yea Right! Maybe 14.99

 

Useing that link I make 359 rwhp with mph and 395 rwhp with ET time.

 

Thanks.....

 

When I Did Mine By Mph It Says 417@ The Wheels And 492 @ The Fly
Then I Check It With E.t And I Get 448 @ Wheel And 529 @ Fly

 

I was told that the E.T. one is based on a 2.10 60'
