How Gearing Effects HP from 1-3rd in 727's

A chassis dyno measures torque and the dyno computer does the HP math. HP is just a simple math problem "torque x RPM/5252 = HP".

Gearing provides torque multiplication, but it doesn't change the engines HP or torque output..

Telling me how much HP change per gear would cause me to laugh in your face and walk away from you shaking my head..... It would tell me to avoid investing in your product.
