I drove a '17 M2 6-spd with dinan stage 4 installed. It was fantastic to say the least. Way better than I remember my mildly tuned 335i. Unfortunately there are no stock M2s or M2Cs to compare it to around here in 6-spd (there are a couple of Cs with DCT). I imagine the 100 extra horses makes a difference but how much? Just looking for a comparison as I prefer black sapphire over the white that this one has. Just wondering what I'd be giving up for a color preference. And yes I could add the stage 4 but the white one is priced identically to stock versions on Autotrader so it seems to have great value built in. Anyone have experience to share?

Next question...what the hell does OG stand for . I've tried to figure it on my own...honest.

Dinan claims stage 4 tune adds 100 hp. So the 2017 M2 has about the same hp as an M2C.

OG is a funny abbreviation used here to stand for original. Personally I would not buy a used M car that has been modified. The mods add zero to the resale and may actually lower the resale value.

As a daily driver there is very little difference between a M2 and a M2C. On the track, a M2C is a much better car. So it matters what you are buying an M2 for as to which car is better. If you decide on an M2, I would look at a 2018 due to the LCI update with the LED headlights and taillights. A 2018 M2 can be had between $40,000 and $42,000.

Thanks DanG. The LCI sounds good. I didn't take that into consideration. But the stage 4 is still about 60 hp more than the C. That's a fair amount of "free" HP to leave on the table. Either way, it's clear that I need to drive a stock version to get any real idea for myself. It's really the only way to know for sure.

And thanks for the OG definition.

Modified cars are often seen as tainted by a lot of purists. I see the argument, however the flip side of the equation is that anyone who is willing to spend thousands modifying their car is also more likely (not guaranteed) to care about the maintenance and won't cheap out on it. They're also more likely to understand how cars work and have more mechanical sympathy (waiting until it's up to temp etc.).

If you can tell the current owner cares about his car, isn't a complete hoon and it has a solid maintenance history (interval services etc.) then I personally would prefer that over a similarly priced stock car that is serviced only based on the BMW service intervals.

OG stands for Original Gangster.

It doesn’t add 60hp more than the C because stock C are making around 470-480hp at the crank (about 420-430whp) hence why Dan said the two cars are about the same. The 405hp official rating from BMW for the C is severely underrated.

That I did not know! Much thanks for the clarification.

Interesting perspective, thanks

I think these numbers are way exaggerated, the m2c makes 405 at the crank...

False. The Comp makes way more than 405 crank. 397 wheel is a bit lower than most I've seen, but even that with 15% (very conservative) loss puts it at 467 crank.

That's Dynojet which is known to read high. 353whp for the OG is a good indicator.

Na most m2c put down 370-380 on mustang.
From what I've seen anyways

Mustangs are called "heartbreakers" because they rate lower than all the other dynos.

We see what, 375-385 on mustangs, 390-400 on most other dynos, and a few showing up as 400-420whp. Truth is always somewhere in the middle, but even with a 15% drivetrain loss, we're talking real world flywheel HP at somewhere around 442hp-490hp. Safe to say, no matter what the truth is in that range, accounting for standard deviation per car, that the M2C is running at WELL over 405 crank hp. Lets be conservative and call it 455 crank HP, eh?

You know that's not flywheel horsepower right? There's usually 15% difference between the HP measured at the wheel, and measured at the flywheel.
I didnt hear him say it was corrected for flywheel anywhere in that vid, so we haveto assume it's wheel horsepower, because that's what dynos typically measure.

[GoneIn4Secs]

Its not wheel hp

Look at this thread:
https://f87.bimmerpost.com/forums/sh....php?t=1710272

First screenshot, you see two dyno runs- one at 402.9 hp, estimated 463.4 flywheel hp, the second run for 425.5hp, estimated 489.3 flywheel hp.

This describes the difference between rated/measured hp, which is ALWAYS wheel horsepower, and estimated flywheel hp. Unless you put an engine on an engine dyno, you wont get measured flywheel hp, you will get estimated flywheel hp, where they haveto guess the drivetrain loss is 15% roughly. (honestly its probably less than this now days, with modern transmission tech)

If you have proof to support your position that all these dynos are measuring crank/flywheel hp, feel free to post it. (but they aren't)

edit: you'll also see in that thread, the readings are accurately called "whp" or wheel horsepower readings. So they are measured at the wheel. like all dynos do, except engine dynos.

This was already vetted like last yr when the m2c first came out, its not making close to 500 hp at the crank, if it did , thats all we'd hear about

Yeah, I just don't trust any dyno readings from europe, since they often avoid WHP and the car has a slightly different tune for the non-US market. McLaren720s has a couple of dynos on local dynomometers here in Seattle. If I had to guess, i'd think the M2C was making somewhere around 450hp at the crank. We'll never know for sure, but I think its safe to say its a above 400, but below 500 too (just looking at trap speeds.)

I have a 2018 LCI and added the Dinan "stage 4" big turbo intercooler exhaust kit when I reached 1,000 miles on the car. Dinan sells it as their P2 install. I absolutely love the change with added power and sound. The power add is more than noticeable, its intoxicating.

No wonder I loved it so much!
