I don't know why so many people have this screwy idea that torque and hpr are somehow seperate things. They're not.

Hpr = torque * rpm

So oviously since a turbo increases your power but doesn't make your engine rev higher it increases torque, it might not increase it at the peak though, it might increase it after the peak in the higher rpm range.

That's the equation. When taking about acceleration what actually accelerates you is rear wheel torque. But rear wheel torque isn't = to engine torque it's related to engine hpr since there's a gear box in between. What I mean is rear wheel torque is higher the lower the gear (hence harder acceleration)

Hpr is ALWAYS a better measure of acceleration potential since it factors out the gearing.

Basically in the end torque is a stupid marketing gimmick. because take this scenario - One engine makes 50 lbs of torque at 10,000 rpm another makes 80 lbs of torque at 5,000 rpm the one that spins to 10,000 is going to have 20% more power. If you gear it down to 1/2 what the 5,000 engine is geared for it will accelerate harder and make more rear wheel torque, even at the 'mid-range'
