rpm/gear/tire calculator

It is a little complicated, but a great tool.

You'll have to 'put it in gear' to work.

So: Change to automatic, put it in (D)rive (or use the 4-speed and put it in 4th gear), chose your gear ratio or change it by clicking into one of the fields and select this field. Now change the Throttle to whatever rpm you need and see how fast you'll go.

The HP is calculated, you'll have to put in your 1/4mile top speed. It'll give me 301hp in my 440 Charger which ran 13.9@99mph. Sounds about right I guess?

Cool looking, but very confusing and difficult to use

I tried changing the axle and transmission ratios…  and it wouldn't let me, or I'm not doing something correctly?  I don't know… whatever   

Also how do you change HP, for the estimated 1/4 mile?

thats cool dave .for some one who no's nothing about r p m's thay can see how it works nice
