Look around and I didn't see anything of something like this but wondering about watching the butterfly valve open and close in the throttle body when when revving the engine. I'd love to see this because I love attention to detail especially in games like this.

oh it was requested a really long time ago, would explain why you didn't find anything on the matter

anyway - if i remember right, then it's very low down on the to-do list
