BOOST CONTROL on SUPERCHARGER

[Ae86drift]

Is there anyway you can put a tap style boost controller on a supercharger setup???

[Lloyd]

No, boost level is controlled by the size of the supercharger/crank pulley ratio. You need a bigger pulley to run more boost. If you got a 175mm crank pulley you could put an adjustable tap on the bypass valve and have it run up to 14psi boost, but then even when you ahve the boost turned down you'd be stressing the crap out of the supercharger by running it at its limits even when on low boost.

Short answer: Nope

Shouldnt people have a basic knowledge of their engine before they consider things like a boost controller? I mean come on, boost tap on a s/c?!

[Bazda]

they do make aftermarket abv's (like a external) that can vent off air back into the s/c if boost limits get to high, my mates car came with one and u just turn the bolt on the top of it if u want to lower the boost.
Standard ones vernt off after 10psi, thats why you do the abv mod when putting a bigger crank pulley on so it by passes the abv.

but you want to try up the boost i suppose, well u need a bigger crank pulley
