No, suoerchargers work by super heating the air that is forced in, there are kits to After cool them but as far as lower boost no they need nothing.
ok time for a lesson on superchargers. there are multiple types of superchargers. it all depends what supercharger you are running.
type #1 Positive Displacement. this is the type that most people think of when you say SC. also most common is a roots type but there is also a LYSHOLM,Sliding Vane, G-lader, Wankle blah blah blah not important. either way they are internal or external compression based. oh and they are Pulley
based platforms and with this method boost is granted throughout the entire powerband and rpm range. press the gas and you have boost.most people think of a roots type SC (oldschool muscle guys, jackson racing and so on.)
Type#2 Exhaust driven. this basically operates like a turbo charger with slight variations. with you can use a IC with. alot of S2000 and Z guys use these.
Type #3 Dynamic SC like Centrifugel. These are basically a shaft driven application which do not provide any boost at low RPM's which make it a good option for a stock compression motor. in my opinion these SC are a no go. lets see you get no boost at low RPM and you get lag on the top end. boooo! also this application can use a IC.
also with a Positive Displacement it is optimum for Auto trannies or trannys i guess not tannies lol.
