Swedish tuner claims 420 PS out of completely stock M2 and 450 PS with turbo back exhaust, sport filter and upgraded intercooler. On the crank, not the wheels. Of course.

420 PS = 414 bhp.
450 PS = 444 bhp.

I don't exactly know how that translates into whp but I guess it's slightly over 400 at least.

It's 420 whp stock. Very under rated. Very documented.

Again, an OTS Dinan tune and a DP on an M2 isn't getting you anywhere near that. On pump gas anyway. Custom tunes and DPs have been showing near the 380-400 whp mark. Which is great, but not the Dinan tuner the poster is mentioning. It takes Dinan a larger turbo to hit, say, 430, per their own offerings. Which STILL isn't actual S55 power. Custom tunes, ethanol blends, DP...there's been talk that 450whp may be obtainable with the N55. But that is not even close to what you're getting from a Dinan tuner and a DP on pump gas.

Some people in here are completely talking out of their asses and relying on random high-reading dyno runs. It is well-established what the stock turbo on this motor can do.

Here are some of the highest numbers so far. DP and a CUSTOM TUNE. 380 whp on 93.

RPMs DP and Dinan tuner would be lucky to see 360 whp. Only about 60 whp down on what an S55 is making.

In either case, that's not S55 power, and not the mods RPM was mentioning. The S55 is making like 460-480 bhp, stock. You're not touching that with an OTS tune and a DP on pump gas.

Or the M3/M4 friend is either an indulgent nice dude who just topped up his fuel tank and wants to give his M2 friend by all means a better feeling, or he's less skilled to shift his M3/M4 than his M2 friend.

After 40 pages of this are people still comparing the s55 to the n55? Don't get it . Thought this debate was over 6 months ago?

Did the 1M guys go through this 5 years ago?

Here's a dyno with Dinan sport tuner only, approx. 365. I'm adding a Fabspeed DP next week and am hoping to top 380. Not bad but still 30 WHP short of the M4 that Fabspeed dyno'd (410 whp).

I wasn't debating that, just further information to the supposed "400 whp limit" of the N55 with stock turbo.

Personally I'm fine with the 365bhp it makes stock. I find it to be adequate but it's still nice to know that if I grow tired of stock power I can easily get more out of it.

There were a lot of talk about the 1M not being a proper M car as well back in the day. Nothing new under the sun.

People forget. In 5 years the M2 will be a true legend as well.

Entertaining information for you - SportAuto in Germany did a supertest on an M2. Unlike the US magazines, they do a real test on the car - 2 track times, measure the specs on the suspension of the test car AND even dyno the engine. On the dyno, the car put out 400PS. Over 8% more than spec. Just the stock motor. The real benefit of an M3 motor would be to tune well over 400. I'll add again that with the little Audi RS3 at 400 hp, little doubt to me that the M2 will need to have more hp.

As we know, some official M2 figures:

• max output: 272 kW or 370 hp (metric) or 365 hp (mech) @ 6500 rpm;
• max torque: 500 (465+35) Nm or 369 (343+26) lb-ft @ 1400-5560 rpm.

Akrapovič tested a stock M2. Their test results (see here):

• max output: 284.3 kW or 386.5 hp (metric) or 381.2 hp (mech) @ 5500 rpm;
• max torque: 558.8 Nm or 412.1 lb-ft @ 2500 rpm.

As Akrapovič officially claims those figures, for sure they can back these up with verifiable test results (though I'm aware that we should be cautious about dyno results, as all depends on the particular dyno set-up / test environment specs).

Hence, no dramatic hp increase is required to bump the M2 to 400 hp (metric) (294 kW or 394 hp (mech)) for a special version (ZCP, CS, Whatever), officially quoting 385 hp (metric) or so.

However, there's a catch. BMW M already pushed the envelope of the N55 engine for the base M2. The margin that's left for a power bump is rather tight. Also DINAN came to that conclusion after testing the base M2 (see here) ("These specific parameters allow the car to safely extract as much power as possible out of the engine. On the M2 this task is especially daunting given how close to the edge of its capability the N55 and its turbo are tuned from the factory. BMW did not leave a lot on the table to work with in terms of additional power output as the turbos are taxed heavily out of the gate. In fact, in its stock configuration, the M2 is nearly the equivalent of a Dinan stage 3 tuned M235i (the stage just short of the big turbo and associated tuning).").

I love this guy whos never even driven an M2 but knows everything about them.....And again your wrong wrong wrong.

Just the dinan sport tune makes 370 to the wheels dyno verified. Before and after making some 35 extra to the wheels at the top, its all there. With my DP it made a very significant difference and now I pull on my buddies m3 no problem. Whatever you want to believe, but im having mucho fun and the things a rocket.

Keep bashing what is a honest conversation.

Intercooler next and we will see 400whp mark my words....... $2700 total.

And yes I am very aware M3's make some 410whp and similar torque figures.

The M2 with a sport tuner makes as much torque, lets see what happens with the DP installed in conjunction.

The way I see it is Dinan has an issue on their hands. Full piggy backs and these ecu tunes are not that great from what I see. Of course in Dinans mind its maxxed out. They will NEVER recommend a DP for emissions reasons, and its verified that the sport tune makes more power than their stage 1 map. This is so they can push the big turbo setup for 6K.........

Someone with the big turbo setup just dyno'd their car and the numbers were not great. I see no reason to go to a bigger turbo and risk lag and spend a lot for it.

We will see dynos of a car with a DP and a simple sport tuner and my guess is 385+WHP and 425wtrq. It is what it is and not sure why some people without the car even chime in.

Looking forward to this for sure. Im going to add a intercooler for $600 and call it a day. Its plenty and I mean plenty fast.

How the hell are the last few pages related to 'BMW M2 CS coming with 400 HP S55 engine, in 2018' ??

This is ridiculous. Why is this not discussed on a separate thread(s).

Yes, it completely derailed but the thread is so popular that the mods wouldn't dream of shutting it down. It's a juggernaut at this point, completely immune to off-topic banter.

[marcusfva]

Every day I'm reading that the N55 fitted in the M2 has its limit also given by the same turbocharger we find in the "normal" N55.
But why the turbo charger of the M2 has a different serial number as spare part?

Generic N55 turbo charger:

M2 turbo charger:

https://www.leebmann24.de/bmw-ersatz...ct=11658053153

Same price doesn't mean that they have the same size

B58 turbo charger (cheaper but notoriously bigger than the N55 one):

Any additional info on the M2 CS with S55 engine? Confirmed?

Yes! I said it before...the M2 doesn't really need more power, an S motor is nice, but not necessary. I hope the CS goes on a diet and has better steering feedback.

It does go to show that most people don't care about these things unfortunately.

It's confirmed by Pure Turbo that the M2 Turbo is slightly different than the 235i.

The reason for this is very simple. The M2 turbofold is slightly different from the regular 235 turbofold. And M2 spare turbofolds are not easily available on the used market. So new turbofolds are being bought from bmw to modify them into pure st2 units. And bmw charges big money for them. Pure is just passing on the cost of that to the customer that decides to keep their stock turbofold.

So if you want to keep your stock turbo just go and look for a used or cheap new turbofold that you can buy and set that one to Pure. But you wont find many so probably end up buying a new one from bmw and will pay the same.

Hope that explains."

That's fine, I agree.

But you've just put your foot in your mouth (again).

Let me walk you through it...

You admitted above that the S55 puts down at least 410 whp stock:

Originally Posted by RPM2-85

So you've now admitted your previous statement about making more power than an S55 with a DP and OTS tune was complete BS.

Last I checked, 385 whp < 410 whp. So crushingeverywhere on the power band?

You attempt to insult me in your posts for telling you you're wrong, and then chime back in and completely prove my only point?



Seriously kid...I think you need to read posts before you hit the reply button.

OK, 380 whp then.

But as you said, 30 whp short of the S55. So again, RPM was undeniably talking out of this ass earlier in the thread, as usual.

Now I'll await him chiming in to again claim that because I don't (yet) own an M2, he's somehow entitled to make up dyno numbers, while I'm not allowed to correct him over it.

I think he wants another TO.

Wow, I dont even know what to say to this guy. Get under your skin much???? You even wrote me a personal message with a at the end. Really man?

I dont have time for your BS internet tough guy crap. Yes 380hp to the wheels at least, and im pushing 420wtrq to. I rip my buddies M3 without issues. I dont know why that bothers you so much that you need to write me a personal message about it????? And call me a liar, that I talk outta my ass? I drive his car or mine every day. Do you have an M2 and M3 at your disposal daily? Didnt think so.

PUHLEEEEZE go back to your safe space buddy and let a real discussion happen between actual owners...... Your the only guy super defensive about a car you dont even own. I just dont get it.
