David GerardWild Guesses?
When we were last on the dyno with our then new ProCharger engine, we made 1980HP at 7800RPM with 2.5 inch dyno headers and a big 12" low restriction air cleaner.
We have changed to 2.5"x15" zoomie headers and replaced the air cleaner with a velocity stack. Runs a lot better!
Any guesses on how many additional HP's we added with the change?
Just for "Bragging Rights"!
