Torque Reading

[b.]

Hi can anyone 'translate' this torque reading into Newton Meters please, cause 3300 seems very unlikely.

Look closely, it is a measurement of tractive force only - the unit is Newtons, not Newton Metres.

Depends how the software is calibrated what you get.

Main thing is to check the shape of the graph for the before and after , and also whether you get dips, if the graph ramps like a ski jump, tapers quickly etc.

cheers

if the car was tied down properly it would be better.

what mods have u got? the torque is jumpy lots. how did it appear on the dyno when you watched it? did it look like it was slipping around a lot?

So how can I find out how much torque my car makes?

Hi flowed std turbo, SARD 650cc inj., SARD fuel pump, fmic, LINK ecu.

It's a R33 SII by the way.

I didn't get to see it unfortunately, had to be at work, so can't tell you if it was slipping around or not.

TE(Tractive effort) is the actual torque delivered to the dyno rollers. Actual engine torque T = TE x r / GR. Where r is the radius of the tyre and GR is the final gear ratio. Therefore if the run was done in fourth the GR is 1:1 but the diff ratio is 4.11 in GTST. So say for 17" tyres with 45mm profile. T = [5000(from graph) * ((17/2 *25.4/1000)+(45/1000))] / 4.11 = 317 N.m at the flywheel.

It was on the dyno 2 days ago and I asked for a torque reading and thats what I got.

I might have to go back and ask for a readout for Dummies!

Wow! you make it look easy. Spot on with the tyres too!

Cheers mate thanks for the help.
