Not too sure about the other bits, but wow, looks great! Bet it sounds the business too.

Nowack needed to wind up to 9000rpm + cams + exhaust + remap etc to find 400bhp from the M3 engine, so it makes you wonder how these other tuners can get anywhere near with what are essentially breathing mods and a remap.
No doubt they will have some shady dyno printouts to prove it![]()
but he DID get the cams, and the zorst, and the pulleys, and the remap, and the de-cat...
or am I getting confused with what you're saying?

Same as the MStyle one we discussed about in the other thread. I reckon this pic they gave is the Eisenmann one... I mean, the number plate has Eisenmann on it!!
TBH I wasn't too happy with their email replies to my questions. very short one liners. nothing descriptive, etc...

Power ~ cfm, and to get that when the breathing is already good, needs rpm.
Rpm needs strong internals/rods, and Nowack wouldn't run to 9000rpm to make peak power if they didn't need to, since it IS cheaper to do cams etc, than strong internals/bottom end.
Thus it makes sense that to make 400bhp you want 9000rpm.
So, chances are even with cams (as per CSL), remap (as per CSL), exhaust (as per CSL), and fancy intake plenum chamber, you probably won't get more than 360bhp anyway.
Point is, it's never going to get beyond CSL levels of output without BIG work (rpm's)...
Thats said, an RPI scoop could net another 15bhp![]()
