Does anyone know of a calculation or formula that determines HP change per compression ratio change? The reason I ask is that I just purchased a set of .060 pistons,(motor is a .030 at present) and the new piston has a compression height of .026 'less' than the original.Maybe the bigger bore will make up for this but since I am using the same heads and gaskets I have become curious about how much difference this actually makes.They are the pistons I wanted and I hope this doesn't sound like a dum question.
