yeah, I know what you mean, also the car will have a lot to do with it, a big merc with 500bhp will always feel slower than a fiesta with 200 for instance.

900 a tonne sounds properly mental, scary even in a straight line up a runway?

Chip and I have concluded that after about 400bhp/tonne much more is pointless on anything except a motorway as youre saying, but it would still become mundane lol
