Eeks! M2 N55 stock only puts down 280whp

A load based dyno reveals the M2 is doing what N55's are known to do, 280whp stock. I thought I would post it here to us F10 N55 guys so we don't feel so bad about ourselves.

They get 360wtq at around 2200 rpm to make them feel fast. Obviously they're lighter so it is technically quicker, but still...

Saw an article about this too. Something is fishy about that dyno reading though from what I've heard. I'll reserve my judgement for later testing.

I do have to say those cars are straight little animals though.

yea that doesnt seem too accurate, its a beefed up version of the N55, how is it going to make that low power.

People are saying on the M2 forums that, that dyno is bull. Couple of things though:
- N55 is known to make 280whp stock on 91oct
- it's a load based dyno
- the could've heat soaked it in previous runs

That doesn't seem right either. Wait for more independent dynos and I'm sure after this plenty will start coming out of the wood work.

Interesting, since it can beat an M4 around Willow Springs per a video review of it.

I'm really surprised they didn't put the B58 in it. Not much more potential than stock with the N55, unless you upgrade the Turbo of course.
