i have a formula that is pretty close to accurate normally, you take the ET/5.825, then cube that number, then take the weightofcar/the cubed number, so a 14.46 at 3400lbs(guess), it took 222.8hp to run that quick
I have to tinker w/ the weight to get probably a more acturate rwhp number, but gives you a good idea.

i like to use www.prestage.com
one thing to remember though, use a calculator that uses your trap speed to figure out your hp. that is the measure of power you get at the track.
ET is a function of how well your chassis and gearing are working more than power. if your car hooks perfectly you can get a reasonable idea from et, but mph will yield the more accurate answer.

WOW, first time I feel one of these were kinda close
I entered:
210 lbs for driver
550 lbs weight reduction from stock 3450
(Best race weight was 2950)
ET 12.48
MPH 110.95
A4 tranny
Calculated:
estimated weight 2971
RWHP per ET 302.10
RWHP per MPH 316.69
I have put down 315 RWHP like 2 years ago.
First time one of these were close, hmmm
Race car - gone but not forgotten - 1997 firebird V6
nitrous et & mph: 12.168 & 110.95 mph, n/a 13.746 & 96.38 mph
2013 Dodge Challenger SRT8: 12.125, 116.45
2010 Ford Taurus SHO: no times yet
Most calculators are ego inflators. They are old and simply do not consider aerodynamics.
Using those calulators, two vehicles, one being a truck @ 3500 lbs and the other a f-body @ 3500 lbs both run 14.0@100 MPH. Are they both going to make 273 RWHP? No, not at all.
It works out that the truck is making near 273 rwhp and the f-body is making near 244 rwhp.
Take my wife's 99 V6 Mustang. It made 167 rwhp and ran 15.3's@91 MPH. Using the old calculators, it would have made near 188 rwhp. If it made near 188 rwhp, the car would have went almost 95 mph with the car weighing @ 3200 race weight, which it does weigh.
I would bet your 3.8L weighs with you in at 3500 lbs. I would bet you make around 212 rwhp @ that weight.
For newer aerodynamic cars, use 5.63 instead of 5.825 and 243 instead of 234.
