Mark, at 4,330 feet (your elevation) you'll have no problem getting this car to 550hp on the pullies I have for the Kenne Bell Supercharger. The Higher the elevation, the less air there is... and the lower the HP. Lower Elevation, More Air, More HP.duramax1 said:And how can you get more hp?? and how much? Would like to attain high 500's true rwhp. That would be my goal.
