Big horsepower 318 builds

Never got this only the track can tell your real hp, for one the formulas to do so probably where figured out in the first place by a mix of dyno and track results so who knows the accuracy of any of those formulas and you can't verify them if you can't trust dyno results. Second your only gonna get accurate results if your car is setup to take advantaged of every last hp, or otherwise is only given you a results of the hp your using. Obviously how your car performs in the real world matters more than a dyno but then again most don't even race their cars on the track so for most it's subjective on what is the best build setup for them.
