M3 CSL on the Dyno

[billy83]

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!

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?

[billy83]

Needed a bit more power (to say the least!) Got rid of the saxo now and have a clio trophy instead. F**king incredible car, perfect for the road!

Any Dyno'd M3s out there guys? If not does anyone know what they usually get?

[billy83]

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
