OK, I havbe been wondering this for a long time. I understand how a dyno works and all, but here is my problem. If you hook an engine up to a dyno and it measures torque at the flywheel and then horsepower can be calculated off that. Fine makes enough sense. Now for a chasis dyno... why does gearing not impact the reading. I mean the whole resoan a transmission has gears is so that mechanical advantage is achieved and you can accelerate faster in yourt lower gears and then conserve gas at highway speeds.
No I know in most aut trannys 3rd is a 1:1, but then you have to take into account the rear end gear. So in effect if I took my car and ran it with a 2.73:1 rearend, then came back next week with a 3.73:1 why wouldnt the dyno read more torque? I mean a 3.73:1 geared car would accelerate faster than the 2.73 geared car would so why does the dyno not read this as more power? Someone explain this to me, it is really bugging the piss out of me
