I've been thinking about a stage2 scoop for the skylark. I was trying to calculate how much power it would be worth. Anyone know how much this mod alone is worth typically? I know our motors work off atmospheric pressure to fill the holes. I also know that pressure rise is proportional to velosity squared. Pv = .5 * density or air * v^2 @50 mph that gives me 1.04 psi increase at the scoop. or about 2.2 inches Hg. This should be a fair amount of boosted horsepower from volumetric eff. improvements. Any guesses out there. worth it on a street car?
