200rwkw Expect Around 600nm?

[letemlaf]

I was look at a friends dyno readout, which says 200rwkw and 604nm.

I was wondering if the torque figure sounds a little high?

car = r33 gtst S1

walbro fuel pump

standard turbo (13psi), injectors, ecu

the torque reading on a dyno is often a fair way out. my old 3.5L magna had over 700nm of torque according to my dyno sheet, and it only had 170hp (from same dyno sheet).

It's tractive torque, not engine torque.

whats tractive torque? coz when my gtr was on 173kw(f*kd cat) it said i made 904 nm of torque

[letemlaf]

isnt hp/kw a mathematical formula worked out from torque?

[Al]

My understanding of Tractive torque ( I may be wrong or slightly incorrect)

Tractive torque is measure of torque at the wheels.

It is the engine torque multipled by a factor that is the result of the gearing through your driveline. Gear selection, diff gears, wheels size (rolling diametre), etc, all effect the reading for Tractive torque.

yep AL is correct.

basicaly, get the tractive torque, divide by 4.11 and multiply by 1.15 to give 15% tyre flex. My managed 1409nM tractive torque, so that is about 360nM of torque.
