Here is a pretty decent one. It has worked great with alot of the numbers people come up with on their cars as per 1/4 mile and dyno numbers.

For example...a 3900 pound car turning low 10's, makes around 757 rwh.

You can also put in the mile per hour and weight and it will give you what you car is putting out on a good run too..

Its basic..but it works

no prob Pete! I figure alot of guys here that havnt been to a dyno could use it. They can put their times in and car weight with driver and know about how much rwh they are making.

Using a heavier vehicle those things stink.

I ran a 12.2 @110 and it says I am making 522 with the ET method and 515 with the trap speed method........but I only dynoed 420.

Cool toy nonetheless.

You know that the Dyno can not calculate the power you get from the cold air system while going down the track, so the real HP for racing would be higher......So I think anyways.
