You need a boost referenced power fuel valve and 6-8 sizes bigger fuel jets if an intake air compressor is used, because more air is crammed into the same small cylinder space so it needs to have the ratio of fuel remain the same so more particles of fuel need to enrichen the charged air, or else it will burn lean when boost is produced by opening the throttle and revolving the engine faster, as opposed to when idling- when allowing the transmission to move the car with less torque, up to cruising velocity, intead of opening the throttle/air intake, progressively spooling faster and faster the turbines which cram air until its packed more densely than atmosphere...and certainly isnt activating a carburetor via vacuum like in a normally aspirated air/fuel combusting car without compressor, where normal amounts of fuel are mandatory for that to work, where the only compression is within the cylinder...which is why boosting/chargine the air makes a smaller engine the same as a larger engine using only its displacement to create pressure. This radical transformation of the air density after boost starts occuring is why at first, the car only needs regular cruising nd idling lower fuel amounts to normlize the air/fuel ratio, but then as more pressurized air comes into play, then more fuel needs to be deliverable. An upgraded electric fuel pump is needed for fuel injection cars to achieve this, but even on a carbureted car enough fuel must be ready to move so a better pump, yes. The compressed air charge heats up, though, so you must cool it back down via air to air intercooler (simple) , air to liquid heat exchange and intercooler, or water/methanol injection which chemically alters ignition octane giving it a hotter flash point so it can be compressed more before it is ready to explode (which is how power reaction increases) and the water transfers some heat away from the fuel its mixing with but doesnt interfere with chemistry...this system also cleans your engine with no harm! Good way to make pump gas handle more pressure, thereby unleashing more power and preventing dieseling or detonation, which destroys engine parts. Bye bye engine if the compressed air isnt cooled down and stabilized and mixed with enough fuel, if the engine naturally has a compression ratio in the cylinders of 7.1:1 or higher. Theres no reason not to cool it and still safely make more pressure like modern cars 8.1:1 and up. But premium pump gas octane works fine without water/methanol injection systems necessary. The water/methanol is either instead of or in addition to intercooler for HIGH boost producing turbos 20 p.s.i. or more, as its just going to help even more than only an intercooler, but the intercooler works fine enough, alone...a good one built right-tall, not deep and not long...mounted getting fan-sucked air over it; in front of the radiator; and therefore ambient wind from car moving forward. You need to run high pressure oil line from engine to turbo housing to cool plus lubricate it for longevity, and a low pressure/fatter line drains it back out to the oil sump. Other than that, the only hard work in installing a turbo is making sure your crank, pistons, rings and connecting rods are solid enough for more power by it being a car already built for high compression and power with block and head which wont crack or distort or unevenly press upon a gasket or you need to swap in better parts. Heat wrap, heat wrap, heat wrap. Its easy if you know what basic criteria are mandatory. Must have a bypass or also named a blowoff valve located after the turbos compressed air exit, so when the throttle plates close and the engine no longer can take in that pressurized air it wont press backwards at the turbochargers turbine, rather it can escape outside through the valve which opens when that pressure triggers it! Its just interesting how widely, easily adjustable carburetors are for added power unlike fuel injected-computer circuitry regulated intakes where you need to replace injectors (not too hard), upgrde fuel pump pressure, reset and fine tune the computers software program...I mean, thats also fun and more precise in that way, but for lazyasses such as me, Ill prefer carburetion any day. Now, a video to unstress from all of the school lecturing. youtu.be/MnoDIN0vEhg
