I had a 2018 SS 1LE and now own a 2020 M2C. I just got back from a local dyno with the M2C which is the same shop that dyno'd my SS 1LE, both in stock form.
The SS 1LE was rated at 455 hp and dyno'd 393 hp (84 degrees, 56% humidity) which was about the loss I expected. My M2C just dyno'd at 406 hp (72 degrees, humidity 36%), oddly right on the money for what BMW claims. I'm looking for my SS 1LE dyno print out because I'm almost certain it was noticeably faster. I don't know if it's a gearing thing or maybe the total area under the curve, but I found the results interesting. 2020 M2C stock: View post on imgur.com |

https://f87.bimmerpost.com/forums/sh....php?t=1710272 Looks like he then ran again on the original dyno and did not get the big drop off (right before tuning his car) https://f87.bimmerpost.com/forums/sh....php?t=1711637 I wonder if the ECU limits power at high RPM's if it detects that conditions are not ideal? It doesn't seem to matter too much to peak power, but area under the curve would be hugely affected. |

This isn’t a surprise since most M2C dyno over 400 whp stock and they are seriously underrated by BMW. As for the Camaro “feeling” faster, that’s another story. The feel and actual numbers/performance can be two different things. BMWs tend is vibrate less and isolate more sound which removes some of the “feel” of speed. Needless to say, the M2C is a much better matchup for the Camaro SS, than the OG M2.

I recently re-dynoed the car properly and made 430whp with a perfect power curve. Also, his power curve is actually very good. What you see drop off is the torque curve which is also correct.

LT1 Camaros will dyno at 388 - 406hp depending on the dyno. But the TQ is always flat and high. Throw a Cam in that motor and you get extra 100hp and 50lb/ft easy. More with supporting mods like intake and headers. Even with just intake and tune reputable tuners like Livernois Motosports advertise 440+ HP and 460+ LB/FT.

I think folks lose site of the fact that 400hp isn't a lot anymore. I had one of these play with me on the highway. No match for Fury Kitty, but not really a fair fight. I was impressed with the SS for sure. Probably stickers for half the price too.

Video games actually really helped me understand this phenomenon. Back in the day I used to play a lot of Gran Turismo 5. One of the tuning options in that game was a "horsepower limiter." The way this limiter worked was pretty hilarious, it would just draw a horizontal line across dyno graph at whatever power number you wanted, rather than actually shrinking the curve as a whole. My trick for drifting would always be to tune a car to like 800 hp, then set the horsepower limiter to something like 450 horsepower. The result would be a normal looking power graph up until the car hit 450hp (at something like 3500 RPM.) Then it would just make exactly 450 hp until something like 7500 RPM. The resulting car would be SOOO much faster than any other 450 hp cars in the game because you were always in the power band no matter what and the power delivery was always incredibly smooth as RPM didn't really make a difference on power to the pavement. It's actually something I like about the M2C, as BMW took a similar tact on the top end. It makes less power than an M3/M4 but it makes its peak power for quite a while. I suspect the linearity up top is also partially why so many people enjoy drifting it. It may not be the same area under the curve as the Camaro, but in its own right, it's doing pretty good in that regard (for a 3.0L) |
