5:46 I think you would had to tune the original car quite a bit to get that kind of engine performance in practice. The original car definitely didn't have coil-on-plug system which allows for much stronger spark than the original design. This modified engine also seems to have some kind of injection system instead of carburetor which makes throttle response much quicker than the car would have originally had. The throttle also appears to be drive-by-wire variant which makes it a lot more forgiving for driver than the original fully manually operated throttle.
