Z4 M Coupe Dyno

Dynoed the M Coupe last weekend, and was pretty happy with the results.

The Dyno was a Dyno Dynamics Dynamometer.

Mods:

- Factory DME tune
- RPI Air scoop
- BMC Air Filter
- Carbon filter delete
- OEM M3 CSL Headers (no cats)
- Custom Catless Mid pipe with H pipe
- Stock x pipe
- Stock exhaust
- 4.10 Rear Differential
- 19" DPE SP16 wheels

The car put down 297 RWHP at 7800 RPM and 268 RWTQ at 4800 RPM

Now to get a tune and raise that rev limit

There is a carbon filter in the stock air box on North America versions. I'm not 100 percent sure why it's there in addition to the air filter. I took it out many moons ago with no ill effects.

I WISH our cars had the N54 in them. My 135i COBB Stage 2+ was a freaking monster.

It's emissions related.
There are several old threads on this topic, I don't recall all the details though.
But there really isn't much if any performance impact to having it there.,
