3 Great sounds here, would be a great help if someone can try to make them, I have tried in Shift + A but i suck. It would be great if the rev limiter can sound like it does in the videos too.

ANd sorry all that rev limiter sound can only be recreated by taking the car in LFS and full throttle to max RPM. The popping sound you gonna hear is the engine disintegrating.
