M3 CSL on the Dyno
Discussion
Put my CSL on the dynos at Thorney motorsport this afternoon and got 310 bhp at the wheels and an estimated 373 bhp at the flywheel! (its bog standard but might've been a press car so probably fellted a little 
!)
Well happy
!!
Anyone else dyno'd theirs and if so what did you manage?
Also would love to know what normal M3s get as well.

Thanks mate, think the guys down in munich must've done something to it! It always seemed stronger at places like VMAX where it'd always pull harder than the other CSLs and quite regularly beat ferraris to 120mph.
My bro had his GT3 done (this has been chipped) and he got an estimated 412 bhp at the flywheel, 346 on the road.
Both left with big fat smiles on our faces!
John said he thinks people should quote power put down to the road because there's so much scope in the estimation process but i wasn't complaining!

How did he get it to rev beyond 6k on the dyno? Impressive figures!
I was told that it could'nt be done, however was speaking to someone who had one of the dyno and they were asking me if you could run one, i said.. as far as i know (I have never done one) you can't but it might be worth doing the standard BMW trick of pushing and holding the TC button down for 4 secs.. and apparently it worked!
Thats what he did. Ask John at Thorney about it but i'm pretty sure he said you have to put it on the rolling road then turn the car off for a bit. Then its something like turn the car on press the sport button on then holf the DSC button for 10 secs. Sometimes it works and only on some cars but you usually get 3-4 runs before the ecu realises whats going on and stops all the fun. Peak power was at 7800 so it must've worked on mine!
At the bottom it says "shoot 6"
John said something about this, how does tire pressure affect the figures?

I think they just put the best engines in the CSLs like they do with GT3 RSs. Most don't hit the quoted power, most hit around 340-350 apparently.
Porsches are supposed to hit their power far more regularly: "they have especially strong horses in Stuttgart" ... or so they say!
CSL's a much better car tho

Yep, it was a good car. We specialise in E46 M3's and CSL's and dyno'ing them is an art form as the DSC can be a complete pig. CSL's seem to give reasonably good numbers, M3's less so but a lot of tuners just run them to 6500 rpm then just extrapolate out the full power figures, we run them to full power.
I had my E46 M3 (smg) cab tuned and dynoed at Kelleners Germany.
Standard 327hp
391hp with the following: Supersprint race kats, unsilenced centre section, race lightweight rear silencer, Kelleners race cams, alpha-n management, remap and csl type carbon airbox. Car also had a 4:10 diff fitted (obviously no gain in power with this)
