HI guys,
Ive never taken my car to a chassis dyno and I have a couple questions.
DO they specify a certian gear to be in when they take their readings?
Do they need to know what your rear end ratio is?
Do they need to know tire diameter?
I guess what im getting at is how it works exactly. If I understand it correctly the dyno is measuring torque at the ground and horsepower is back calculated through an equation something like hp = (RPM * torque) / 5252.
But what im wondering is you would get diffrent torque readings at the ground in the diffrent gears correct?
Can someone clear this up for me?
