My M on dyno

Which bit are you enjoying the most the sound or performance ?
TBH both,definitely feels sharper more responsive and no negative effects of Alpha N.
But the big kid in me can’t stop grinning at the sound 👍
 
I love the sound of an S54 at high revs! :thumbsup:

And 388bhp is very impressive - where did you get the extra 50 from? :lol:

Those are excellent numbers, you must have more going on with your engine than just a CSL airbox?
Or the dyno/operator is using the wrong transmission loss % :P

I love it too, but only as long as it's someone else's S54 being taken over the standard RPM limit :D

Really don't like the high revs in person, from outside the car though...just sounds like it's going to explode :oops:

Agree with you on that,heart in mouth after signing disclaimer and hearing my own car at full chat. :rofl:
Worth it in the end :D
Thought probably only come away with 15-20 bhp increase as she was bang on 337bhp on health check run.
To come away with 388bhp was a big surprise

and this is why one has to take the result with a massive pinch of salt and it is only useful to compare before and after results.
 
That number seems right from memory if you've got Schrick cams to complement the other mods! Very nice though
 
I’d also love to know what’s been done :)

Cams, airbox, an exhaust of some description plus the obligatory remap? Anything else?
