How do you increase Torque?

[Rockefella]

How to increase torque:

---1. Save spec sheet.
---2. Open in Notepad.
---3. Edit torque figure.
---4. Save and re-open on internet.

You don't need a big V8 to get shitloads of torque...

406 ft lbs of torque from a 4.0l I6

[deffenbaugh03]

correction:
Power = (Torque * RPM) / 5252

therefore Torque = (Power * 5252) / RPM ?? i dunno i'm not the greatest at math

And i think this has been mentioned before but engines with larger strokes normally produce more torque.

This is because engines with larger strokes cannot get as high of RPM's therefore since you divide by the RPM you get more torque because your dividing by a smaller number? I made that last part up but it makes sense right?

just get 1 of'em diesel engines from big rigs(18 wheelers, whatever else you call), or that diesel engine that is like +-25400L, and like 5 million torque by 102 rpm.

Ummm you going to need to give units if you want to use specific numbers... are you using foot pounds or newton meters, and kW or hp? i dont know any of the numbers anyway, but you need to specify your units in any case

Q) How do you get more torque?

A) Burn more fuel.


Next question!

Are you stupid or something? To tow a 9000 pounds down a drag strip from a 6000 pounds vehicle full of 7 full size 400 pound adults with a combined 50 pounds of McDonalds between them in under 10 seconds... of course.

When in America, order more food

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.

I disagree. Technically the change in pressure and volume within the piston cylinder is doing work. This work takes place over some time interval and therefore can be equated to a power. The pressure exerts a force on to the piston which generates a torque on the crankshaft.

So really an engine starts with power and creates torque and rpm.

Also, I don’t see how torque alone is better than power, in terms of performance figures?

[Orefus]

wait wait. so after a certain point a car dosent need torque? only hp?

[P4g4nite]

a certain point of what?


Having high torque means you can cart heavy stuff, like your own ass, up hills.
Like in truck engines.
Having high power means you can do the work (make torque) higher in the rev range and thus hit higher top speeds.
Like in F1 engines.

[Matra et Alpine]

Torque ultimatesly comes from the expansion of the gasses in the cylinder.
So getting more fuel/air mix in their and exploding it more efficiently will increase cylinder pressure and hence torque.
ASSUMIGN you kep everything else the same.
Then you increase stroke to make better use of those expanding gases.
Roughly double the stroke, you'll double the torque.
BUT when you increase the stroke you dramatically increase the piston dynamnics and inertia as they are travelling twice the distance. THIS then limits the revs and the HP available to you later on when you want speed.

Engine designers and tuners play with all these limits to provide the best compromise for their market/race needs.

Sorry it's foot pounds and horsepower

Meh, I drove a 6/7 litre I6 tractor with 180hp and 800nm of torque

[quattro_20v]

I drove a 420 hp truck, I think that has about a 12 litre engine and like 2000nm of torque :P

But anyway, if i want torque get a turbo diesel, altho diesels suck in high revs

[Orefus]

no, ugh my bad, what i was trying to ask was something like this. What does torque do for a car in a race?
