Our cars made 340whp, but so would every Z on this board with the similar modifications. Theres no magic fuel/unicorn blood additives on Long Island.

These threads are basically useless because this is not the only dyno that will read abnormal, high or low. All that matters is delta, with basic bolt ons (intake, exhaust, hfc or test pipes) plus a tune, you can expect ~40hp increase over whatever your car made baseline. I would go so far as to say adding in a lightened flywheel and underdrive pulley you could get close to +50whp over YOUR baseline. /endthread
