Disclaimer: This is far from advanced, scientific, and is imprecise at the moment. Its imprecise a little at the bottom, and is way off up top once you get into the 11.1 range (more HP would be required than that, especially taking into account the time to upshift to 5th for cars with the stock rev limiter).


But for those of you that like to bench race, I've made a calculator based on dynos I've visited, as well as various Evos trips to the dragstrip.

The first column is ET (Quarter mile time in seconds based on the corresponding horsepower). This is, of course, based off a reasonably good 60 foot time.

The second column is trap (Quarter mile trap speed in mph based on the corresponding horsepower)

The third column is Dyno Dynamics wheel horsepower.

The fourth column is Dynojet wheel horsepower.

The fifth column is Dynapack wheel horsepower.

The sixth column is estimated crank horsepower.

Kind of interesting, good job

 

Actually seems quite accurate.

 

ya that seems pretty goog i made 360 to da wheel at turbotrix(dynojet) an ran a 12.3 at 114

 

Thanks.
The cut and paste didn't come out as pretty as I thought when I imported if from Excel. Anybody want me to upload the actual Excel document with the formulas so you can tweak it to your liking?

 

465whp on dynapack i run 118-120 traps so pretty accurate really

 

not too shabby.. i call sticky!!

 

sticky, fo' sho, dang geeks, hehehe, love it.

 

only 2 whp off from my trap speed. 109mph @ 317 djwhp. not too bad.

 

Excel version. Way better.

Edit: Nevermind. File type not supported. I have to upload it as a Word doc.
