Online Horsepower Calculators

I always use the track time when people ask how fast it is. That's a sure indication of how it runs. It's those who ask how much power it makes that I don't know how to answer. Typically I just say around 550. But I try not to get too caught up in the dyno/calculator numbers much. I used the Wallace calculator that had inputs for hp, weight, gears, tire height and it came up with this:

Power to Weight Ratio: 6.24
60 Foot E.T. : 1.49
1/8 Mile E.T. : 6.77
1/8 Mile Trap Speed : 100.45
1/4 Mile E.T. : 10.72
1/4 Mile Trap Speed : 125
1/4 Mile Trap RPM : 5940

Those numbers are damn near spot on what I run except the rpm is about 1000 less than what I go through the traps at. That's guessing on my weight of 3370 with me in it too. Thanks for the input so far!

I put your numbers into my "Drag Racing Workbench" app on my android phone and it came out almost spot on to what your times are. I was told this was supposed to be used with whp not chp so I am confused as well. If you do not have the app its worth checking out though!
