Added HP factor ?
 

Is there a standard hp to weight factor number? Lets say your combo was added 10 hp, how much weight would that = to?

Nope. It would depend on what your class weight break is. 10 HP X 7.5 = 75lbs where 10 HP X 12.5 = 120lbs. That is why we are usually punished in percentages. Example, toy run -1.25 the index and you get a 3.25% HP hit. So that is 3.25 X whatever your factored HP is. Clear as mud! Jim

basically, it would add 10 x whatever factor the car is currently running at.

be careful though, it may be enough to knock the car down a class if it is close on weight breaks anyway. you see this happening to the CJ's.
