holy buckets this is going to be a lot! lets start
first of all the main attraction! a new intake system!

engines now require at least a intake filter connected with the new intake pipe! but not directly into the engine
lets start

start with either a, turbocharger, supercharger, NA intake, or centrifugal supercharger, connect it to the new THROTTLE! along with fuel and boom its don- wait a minute oh i almost forgot!
THE NEW EXHAUST SYSTEM! new exhaust pipes, exhaust, flames that are related to the engine temp/power!
and there could be a control panel for the throttle so it dose not have to be Manuel
details:

NA intake: no lag, no additional power,

supercharger: as fast as the engine can wind up, decent boost, makes cool sound "MEEEEEEWWWWW"

turbocharger: turbo lag, strong boost, makes cooler sound "WOOOOOOOEEEE"

centrifugal supercharger: as fast as the engine can wind up, sound is mixed between both, okay boost "MOOOOOOOWWWWWW"


all of these can be connected in any way you want! the boost gets built up after each stage for example

basic setup: NA intake > exhaust pipe (coming from a piston(s) ) + Turbocharger > throttle > pistons


note: resizing can effect the power of the booster: bigger = more power but also more lag

another note: putting for example a supercharger and turbo together creates big power with low lag!

please: make the turbo turbine spin

note: it would be better if you could use a link of some sort from the piston the the wheel its connected to, it will instead starts putting 90% of the boost into the piston and now 10% into the wheel its connected to, depending on boost, puts some spin directly into the wheel to so its easier to reach higher RPM, and also depending on boost slowly steps all the way until the ratio is wheel 90/10 piston

if you are confused i will attempt to explain, this is the best i can do for now.

do you think the dev should add this? let me know in the comments!
