when Mat Watson did the sport plus rolling race the M340i shot off while the G82 M4 was spooling and that was at high rpm (not lugging).

in this race the M2 had no lag whatsoever.

Same hardware in the M2, M3, M4. Same turbo. But the tuning is very different. For example, IIRC the G87 caps out at 2 lbs less boost.

As far as thresholds and boost maps, I don't actually know. I've heard more than one person say the G87 feels more linear than the G82. So maybe the G87 is a tad quicker to come on, but the G82 has more power at the high end.

The actual limit of usable HP is going to vary by situation, and it's an endlessly complex topic. But on a power-centric track, it's easily in excess of 800 HP given typical production car RPM ranges.

Even on the street, if you are roll racing to 100, you are in third gear, and 400 HP isn't going to be breaking traction. (In Mexico, of course.)

You are welcome to try 100 in Atlanta, just don't do it in my neighborhood as i don't live on or even near a race track.

Atlanta Motor Speedway is a great track, and hosts the Bobby Ore school, but I understand what you mean.

I think if Matt was driving the M2, it would've won. It was sub 12 secs consistently in the last drag race with the rs3 , cla, and Porsche.

So, in essence, this is a one car comparison.

While it’s good the ZL1/BW six speed manual is better. (It’s a different gearbox and no torque tube)

I have a manual M3 and find the transmission fine, the TR6060 is better but the G80’s is still good.
