Some say for every 100 lbs you lose, it's the same as adding 6 hp to your engine before weight loss. Some say 10 hp before weight loss. Is there an accurate way of figure? I know hp to weight is key. I know the rule of thumb is every 100 lbs is a tenth in the 1/4. I think it makes a difference of the torque of the engine. I think a 100 lbs is more than a tenth to a 318, and not quite a tenth to a 440. But the question is, for every 100 lbs loss is the equivalent to how...
100 pound loss = how much HP gain???
