Undersquare vs. Oversquare Engines

famous bob said

Still off!, I grew up on a farm w/ 5 diff type tractors on it, they don`t have to be wide open to do their job, the powerband thing don`t cut it in them. One of our tractors had a 6 cyl. Chrysler car motor in it, it was scary fast on the road w/ no governor, another super M was as stout w/ a 4 cyl engine , but certainly not the fastest . As I SAID GEARING DOES NOT CREATE TORQUE, but will cover up a lack of...............

A tractor really has no brearing on your original point. No amount of gearing will make it a top fuel dragster. Again gearing don't do much cause the engine has little power in the 1st place.

Your original point was a 700 hp 700 lbs-ft will smoke a 700 hp 350 lbs-ft cause of the torque difference. Which I point out among other things if both geared properly for the 1/4 mile both will be putting similar torque to the ground nullifying the difference at the crank. But that only works if comparing two engines of the same/similar power.

My point is you don't gain extra power by building 700 hp at a lower rpm then another engine making it at high rpm. Cause when setup right (stall gearing) the differences (torque) will be the same at the tire.

Why cause your not gaining anything. Thats why they both make the same power. But the larger engine will trade rpm for torque and the smaller one do the opposite.
