Need a Good Website Calculator for ET to HP

Thanks,

I don't have the 1/4 ET or MPH, I may get it this weekend seeings how nothing is calculable from the ETs or 1/8 ET and MPH. The Calculators are telling me I have 167hp pulling 2.07 seconds at the 60 foot mark?? It is a modified nicely 408 engine.

If I put my ETs up here for the 0-30, 0-60, 60ft, 1/8th ET and MPH and the 1000ft ET, can you give me a ball park what my "REAL" hp is?
Yes, more or less, IF you can give us the car weight with you in it. Or at least describe the car as accurately as you can, and tell us your weight. (A hundred twenty pound driver will be quicker than a 380 lb. one.)
I've got two 500 fwhp cars, one is low eleven, one is high nines. The difference is weight.
ET is almost worthless for hp calculations if the launch is not optimized. Give us the weight and mph.
