My apologies, it makes its most power at 9500 RPM.
130hp Banshee? Since when is a banshee 400lbs? In 100% STOCK TRIM they are only 386lbs. Lose the 40lb pipes, and you're looking at about 365 once you bolt on aftermarket ones. By your own formula, it'd take 121.66HP, nothing real special, and you could dune it. BUT, just my opinion.
