And you would STILL BE WRONG.
You need rear wheel TQ, not engine TQ which is the number people always talk about. RWTQ is engine TQ modified by gearing. So its useless to factor in engine TQ without knowing that other factor.
Now HP already factors this in.
Now stop and think for a second, which car is faster one with 100ft/lbs or torque and a 6000rpm redline or one with 200ft/lbs and a 3000rpm redline. Now lets the higher reving engine always makes the same hp at 2x the rpm of the other motor. So we have a high torque motor and a low torque motor. Which is faster?
Now what if you just change the final drive by 2x on the higher RPM motor?
I simply cannot believe how dense some people are on this subject. Its really sad.
