I am thinking that the creator of the game or some mod creator should make a way to like blow your engine up like in real life if you rev your engine for too long it can blow the engine up into the hood maybe there can be fire that can burn the car and props and things around it think of it your in manual mode holding letting the car redline for like 45 seconds boom engine explodes and fire comes like 10 seconds later it would be pretty cool i think that if a mod creator does this they can put the link in the comments below this but i appreciate it if you take this into consideration
If you revved for to long, It would overheat before it would blow, Unless you have a rod knock or no oil, Then it would blow up (rod knock) or seize (no oil). If you over-revved, Then it would blow up. Or if you put too much NOS into your engine, It is burning fuel quicker, Making the engine go faster, Which stock engines cant handle (Crankshaft, conrods, etc) and would throw a rod out of the block.
