Such a car would then reach around 400 hp way down at about half of the current actual cars redline!

Either way the cars 1/4 mile time and trap (compared to a regular M3) would be within a few tenths and a couple mph. The torque monster could, depending on the final drive ration get a decent jump on the actual car perhaps below about 50 mph (if traction was even possible). Most other major performance metrics would be very similar. Also the torque monster could do in 6th gear that the real car would need to begin in 3rd, but they would achieve about the same net result.

Why is all this the case, again simply because the cars would have the same (peak) power to weight ratio.
But, an engine with same peak power achieved when the torque is dropping like a stone, therefore has higher torque earlier in the rev range will be faster
