Ok, so if I took my truck with a rebuilt stock 22RE, stock 4.10 gears, stock 28” tires and test it on a chassis dyno.
Then take the same truck only with my rebuilt engine with mods, with 4.10 gears, 31” tires and test it on a chassis dyno, the dyno results would show about the same torque and HP numbers to the rear wheels?
If I took my stock truck with stock engine, tires, but swapped the R&P to 4.56, the chassis dyno will show higher torque and higher HP numbers?
If I took my stock truck with stock engine, tires, but swapped the R&P to 4.88s, will the chassis dyno show more torque and HP then the 4.56s? ... even though in 5th gear I'd running at 4,000 RPMs?
Thanks,
Gnarls.
