Vik Member 4 Member For: 17y 10m 10d Posted 21/10/09 02:39 AM Posted 21/10/09 02:39 AM Guys, after custom flash tuning a BA5spd XR6Turbo with roughly 270RWKs @ 11PSI, what sort of torque should it produce, I have dyno sheet but can not understand it, it shows 1042 NM. Is this possible? Coz high tourqe V8 only produce arround 600NM after any tunes. If it is really 1042 nm I cant stop loving my car then and will blow V8s away.

Sounds like tractive errort or something similiar

Im not sure but only an engine dyno can accurately give torque at the engine.

I know that a 15L Cummins ISX at rated engine speed and full boost (1 bar) will move 47Kgs of air per minute. Doesnt some like much, but you measure the volume of 47Kgs of air!

Do you have the std clutch? Slipping? 600Nm would be a more realisitic figure.
