Lightbulb Simplified calculations for a game

Hey guys!

So I am trying to enhance the game I am making (I'm a programmer! ).
by adding some extra mechanics to the vehicles, especially the simple cars.
I do drive by the way and have some understanding of how the internals work (I sometimes revmatch).

First part would be to enhance the current game by adding some turbo , nitrous and automatic transmissions (correctly).

This is not real-life calculations though, I am trying to come up with a simpler model that neither needs many resources nor is too complex to implement.

Here's what I am thinking to do: Calculate how much power does the engine provide with parameters: current gear,(in some kind of unit - nevermind that), boosts from turbo , vtec , nitrous (im a multiplier function that stacks). Then , calculate the RPMs that the engine is already running on based on gear and current speed (with a minimum RPM of 700-1000?). After these 2 steps , calculate new RPMs based on ΔS (seconds passed since the last frame).

After this calculative algorithm , gear changing (provide some multiplier as well - shifting will be instant on the first place) , rev limiter and sound logic takes place.

This way seems correct and straightforward and rather simple-to-implement to me.

I would like to ask you if this would be a proper way of calculating these stuff (no losses or other complex physics stuff). Also , I would like you to tell me what could be improved.

Upon getting some answers, I will update this post in order to ask/add more stuff as well as post updates on the project! Thank you very much in advance!

Basic guidelines would be to add hp at specific time intervals based upon the throttle position. It would really depend on the sophistication of the current game though and what you are trying to accomplish. A mobile game vs web vs pc will all have very different expectations.
