How do you increase Torque?

Yo, is torque just a side effect of horse power, or can you mod cars to get more torque.

Do you mean torque from the engine, or torque at the wheels? Torque at the wheels depends on the gearing and size of the tires, etc. Torque in the engine is related to horsepower, so increasing one will usually increase the other, but not always.

This has been asked many times search the forums for it before yoou make a new thread.

Torque isn't a side effect of horse power. If anything I guess you could say the opposite. Horse power is a function of torque.

Torque is the actual force the engine produces, a twisting force. In many respects it's actually a far more important figure in terms of engine performance than horsepower. Check out http://auto.howstuffworks.com/horsepower1.htm for an explanation of how you get horsepower from torque.

There are MANY ways in which you can modify an engine to get more torque, from modifying the ECU/fuel-mapping to modifying the intake and exhaust sytems.

power = torque * engine speed

Torque is the 'turning force' the engine makes, and is directly interlinked with power by the above formula.

Tyre size makes no difference to the torque at the wheels btw

lol

therefor

torque = power / engine speed

Increasing the length of the stroke will increase torque or is it increasing the bore will increase torque?

toruqe at the wheels. So bore increases torque?

I don't know, but I think the longer the connecting rod, the more torque the engine will make because it will be pushing down longer and will have more mass, someone correct me if I am wrong please.

Yeah that was pretty bad on my part I'm sorry it was early and I was up until 5 last night on cruise boat so I'm pretty out of it... my bad.

anyways, torque is the force that is applied at a certain distance (radius) of rotation, so its a much greater factor in acceleration than horsepower, but once you pass a certain limit, which is different for every car/tire setup/driving conditions, the amount of force at the wheels is more than the maximum force of friction with the road, and any more torque is useless.

so torque is only for acceleration got it. What increases top speed? Rpm and hp?

Both would work, but increaseing the bore is probably alot easier.

If you want more torque...you could just put one of these under the hood:

The Chevy 572 has 600 ft/lbs of torque, why the hell would anyone want any more?
