Went to the track last Saturday ( thanks to Johhny RoundGuy for setting that up! had a great time .. )

by best time was a 16.249 with top speed of 83.31 .. My R/T's mod includes IP Stage III and Fastman TB... I have never been to track before ..

using the calculator on this site --> http://www.greatlakesdragaway.com/analyzer.htm ,

I get the following : ( I entered in the weight and 1/4 mile time )


Horsepower Results - 1/4 Mile Method
Your Dodge Durango weighs about 5100 pounds and can complete a 1/4 mile in about 16.249 seconds. That means that you've got about 234.95 HP at the wheels, and about 305.44 HP at the flywheel.

Question I have is what is HP the wheels and what is HP at the flywheel?

Also on another calc , I entered in weight of 5100 for my D and HP of 255 ( factory rating on my 2000 R/T ) and calc said I should have done a 1/4 mile in 15.811 with trap speed of 86.206. Does that mean that my D does not really produce 255 HP?

TIA
