Here is the end result of our new 4-inch inlet, taken on a different Dynojet (Crazy Horse Racing instead of Second Street Speed), but using the same standard correction for atmospheric conditions. The custom pipe produced 337.7 rearwheel horsepower (5500 rpm), or about 14 hp more than the stock pipe. Note how fat our torque curve is: no less than 400 lb.-ft. from 2000 rpm all the way up to 4200 rpm. Torque peaked at 445 lb.-ft. (2900 rpm).
