Very nice mate

 

[GazHyde]

Nice numbers, what tune did they apply?

Grabbed some screen shots with the graph so it's easy for peeps to see the data

 

[Delk]

8000 rpm. Thats giving it some speed.

 

[Jon2215]

Alpha N stage 2 apparently

The graphs look good and you are getting good power and torque.

Is the 389Nm at the wheels, or estimated at the engine?

What torque is your gearbox rated at? Z3M is rated at 320Nm.

It looks like it's only rated to 370Nm (https://en.wikipedia.org/wiki/ZF_S6-37_transmission)

 

[Jon2215]

Haven’t got a clue on gearbox max torque but 389Nm I think is at engine

 

[Pingu]

Standard is 364Nm (269lb-ft).

It'll be interesting to see how it handles the extra. It's always fun pushing the envelope

 

[Delk]

It should hold up just fine.

My Z3 gearbox is rated at a pathetic 250-270 Nm (off the top of my head) and I am running around 500 Nm through it at the moment. Its still in one piece after a year and half since I am not doing drag racing launches with it. The drift guys are the ones that seam to destroy gearboxes at a regular rate.

I do have a 420G from an E46 M3 to go in this summer but thats more for the sixth gear then the power rating.
