If you Have a 3300 Lb Stock car with a 275 HP Motor and you reduce its total weight by 400 Lbs or 12% .. Does that translate into 308 HP .. Or 12% Increase in HP ?
Is that accurate or is it More or less ?

You still only have 275HP. you are moving less mass with your 275HP.

A drag racing calculator or slide rule chart could tell you roughly what the gain in E.T. would be and you could cross refferance that to the same weight /more horsepower to compare. The gain wouldn't be as effective if the car is already moving compared to a standing start.If you Have a 3300 Lb Stock car with a 275 HP Motor and you reduce its total weight by 400 Lbs or 12% ..

But you have to factor in Davey lees " bloomquistesque " driving talents that are on par with his " carpentry skills " aka screwing sheets of drywall to metal studs ....A drag racing calculator or slide rule chart could tell you roughly what the gain in E.T. would be and you could cross refferance that to the same weight /more horsepower to compare.

I remember reading in Stock Car Magazine years ago that someone had devised a formula for weight reduction. Ok. I don't remember the exact formula, but the overall factor was, It requires 8 1/2 horsepower to pull an additional 100 pounds, & for every 100 pounds your car loses it frees up the same number of useable horses to go faster. This is just what I remember from the article, it was a long time ago, but I've quoted that figure many times, from the writing. And wouldn't really know how to dispute it.
