Frequently Asked Questions Horsepower and Torque Comparisons

Andrews cam: torqueAndrews cam: horsepowerStock TC 96 cam: torqueStock TC 96 cam: horsepower

Torque and horsepower curves are for various combinations of cam grinds, engine sizes and tuning levels. Different engine sizes (cubic inches), compression ratios and cylinder head efficiency may show widely different HP and torque results on the dynamometer. The guide below shows what each curve means.

Keep in mind that dynamometers will show different results for a similar engine setup. When choosing modifications for your engine, the most important part of the plan is to pick the right cams and head work for the application you want. The best cams for bolt in street use will be milder grinds that do not require head work.If you want a great running street bike stay away from 10.5 compression ratios and dragster grinds. Simple ideas and changes work best!
