So he's saying both those motors output the same torque at the output shaft? Well then they would need a diff that could handle that same torque out the end of the gearbox.

That demonstrates that torque is still what breaks diffs, hp is still irrelevant.

They only reason we all talk about torque (lol) is the cars driven in Datsun land will all be about 4:1 out the output shaft in 1st which will send the most torque to the diff.

An engine that spun at 140,000rpm and produced 10ftlb torque that was stepped down the same way would have the same effect - but using out of this world comparison has only managed to distract crispdollaz from the actual issue.
