I drove it at 310bhp and it was spastic fast and suprisingly grippy. 1st was a write off, but 2nd onwards was just crazy. Not sure what it'll be like at 450 ish. Good thing is we've got full gear based boost control, so we can set it up to the limit of traction for each gear to get max acceleration.
If we manage to figure out a way of getting wheel speed sensors mounted it'll have launch, anti lag and traction control too.
