Online Horsepower Calculators

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!

Use the first link to work out fly and rwhp but the rwhp won't be accurate as a 10% drivetrain loss is not a standard for all cars.

The 2nd link is the one I've always been using and that IS fly hp, that matches with the 1st calcs numbers fly figs.

Should sort it all out.
