Looks like the max boost is early then bleeds off. Avoid its true "peak" HP

Usually we see about ~8whp on M3/M4s with filters/charcoal delete. Same as intakes.

I'm sure Terry from BMS will also get a M2C on the dyno some time. For another comparison. He got 330whp/388wtq with a M2 N55 on a dynojet. More along the lines of what you normally see.

Quite impressed with that torque number. Second independent dyno to have the M2C above the M4 in torque.

What were the SAE numbers?

I agree! I really don't care so much about the stock number since I'll be flashing mine with a CS tune but so far even the stock tune seems pretty good.

Would be interesting to see a boost/rpm graph for M2C and M4. I bet it is simple boost targets. Before 4k M2C is actually making more power, but after 4k the M4 most likely is hitting higher boost targets. M2C will end up making indentical numbers with all the S55 tunes.

How do you get the CS tune? Is it a replica/copy of the factory map? Who sells those?

Bootmod3 has the CS and GTS maps as free OTS maps.

[Shankska]

thank you! this is awesome

OP, I have a question. You mentioned 5th gear was used for runs. Can I assume definitive full throttle at 2-2,200 rpms? I have some experience with the dyno although it has a bit. I ask as it seems the engine would be lugging somewhat in that gear hence not recording accurate data until a couple hundred more rpms.

Thanks for sharing.

Both Bootmod3 and BPM offer factory CS map flashes.

Ah I see you must get the $500 license first though. So I guess free is subjective, but the tool does seem very useful.

Cross-reference to another M2C dyno thread: here ("M2 Competition dyno charts? UPDATED with first dyno results (crank) (Sep 2018)").

We start WOT at ~2000rpm.

Lots learned from this information!

I commented on their instagram asking for SAE numbers as well. Wonder if theyll give them.

Interesting how the torque is delayed until 2500RPM on the S55, but spikes up earlier at 2000RPM on the N55.

That was definitely my first impression when I drove out of Welt...the low end torque just wasn't as noticeble to the OG M2. (And I had only driven the OG for like 10-15 min about 4-5 months ago and I still could tell)

Is your car EU spec or US spec? I didn't have that impression of the M2C after owning both cars.

That is the N55, same thing on their normal BMW models with the N55. My tuned 135i was torquey down low. S55 is tuned to build out power through rev range. After 2500rpm is where the S55 takes over and continues to build more torque. If you look at the HP curves, power deficit continues to grow through out the curve. At 5500 there is a ~40whp difference, at 6500 there is a ~60whp difference. S55 is a more peaky, rev happy motor. With that said, they are both torquey motors compared to the old NA S65 that had less than 250wtq at 2500. S55 is a torquey turbo motor, with a sprinkle of the old M normally aspirated feel.

I honestly cannot believe people care about sub 3k rpm this much lol
