1100 Nm

you'd need 400kW at 3500rpm for 1100 Nm !

why? there was a super charged LS1 making only 260RWKW that had just on 1000Nm torque?

sorry felahs am loading the drivers for the scanner as I write this so will post the sheet

whats the gag?

sorry turns out that just isnt legible lets try this

The dyno is measuring torque at the wheels so it's multiplied by the gear ratio, diff ratio and wheel/tyre size. By the look of the torque curve I'd say it's an auto so the torque converter also will effect the figure.

Is that bottom graph you AFR's?

If so, you may want to get that checked out.

Yeah looks a tad lean, 12.8ish at 5500??

To give you a more realistic approximation of your torque output, you can calculate it with the following formula: Nm = (kW x 9549) / rpm

looking at your graph, I'd estimate your pk torque is about 573 Nm @ 3500 rpm.

ie, (210 kW x 9549) / 3500 = 572.94.

and your still holding 500Nm at 5500 rpm, so you've got a great constant push in the back right through the rev range....

I gather it's a 4sp auto, as the test was done in 3rd gear.

Don't know if you've done any mods to the trans, but your tuner has looked after you by limiting the torque at a sensible level.

cheers.
