Maybe not what you're looking for, but at the straight on the track (coming out of the turn at about 3-4k in 3rd gear, accelerate past redline in 5th gear as long as nobody is in front of you) I took an NSX, Lotus V4 turbo, BMW 540i, 330i, 750i, E36 M3, and various other BMWs. They're even easier in the corners. I can guarantee I'd be looking at the rapidly smaller tail-lights of the Porsche 911 turbo -- that car is insanely fast. I don't recall if there was an E46 M3 or not, but I'd guess that would be close enough to be up to driver skill in the corners.
