haha sorry yeah in torque the dynapack is the only dyno to give realistic torque ie close to engine dyno readings, luckily it has both readings, i just switched it accross to mainline / dyno dynamics figures this car pulled 4299nm.... big differrence.
the only other car to come close to this torque was a 408ci blown v8 with 653rwkw and 1022NM, honestley without sounding arrogant there is no way your car made even close to 1083nm, i would expect closer to 600-650nm from your setup, which is still very respectable.
