tractive effort to Newton Meter

[Winnie]

Have you had it tuned Benny?

[taslucas]

Can someone explain the difference between the two in layman's terms?

Yep the dyno sheet is in the killer wasp thread.

Newton Meters is at the flywheel and Newton tractive effort is torque at the wheels as torque is multiplied by gearing

Ahhhh, cheers, so it's pretty straight forward. Just like kw and rwkw?
How would one ever measure in newton metres? That would only really be factory specs unless you pull your donk out and put it on engine dyno?
So all dyno figures are in Newton tractive effort torque.

[Ben-e-boy]

Right, so the equation is

TE= (T × R × 1000)/r

TE=2300
T= ?
R=4.11
r=412.5

Have a crack and see what you get

Year pretty much, I think some dyno programs can work out Nm

Ok, so I get 230. That still seems a bit light on.
Looking at the equation, 2300 seems a bit low if that is the TE number. Based on your ratio (known) and wheel diameter (known) and there is a constant (x1000) the key number is that TE value of 2300.


Tip tip tip......tap tap tap....

[Ben-e-boy]

Thats what I have been getting, less than a factory NA

[Drewboyaus]

Where did 2300 come from?
I've just gone and compared it to the one from that Nissan forum and he's getting 6300 for his TE figure and I reckon that's more like what you should be seeing based on how much power you're making.
