ok so we went and dynoed my buddies 93 STOCK cobra........got what we expected and then started to bs with the guys that works there i asked him how much more he thought it would gain if he installed some gears.....he siad it wouldbe be any different....the dyno compares the speed on the rear tires to the tach and gets the results? i know gears dont add RWHP they sure as **** help u out, i just surprised that it dosnent show on the dyno.....is that a different dyno that does show the gears?
