I have a ZE in my AE92. I've always heard talk about bypassing the ABV on the supercharger to pick up a little more boost. Is there any downside to completely taking it out and fabing up a pipe to take its spot?

you don't 'pick-up' boost by doing the ABV. it helps when you are running more boost via larger crank pulley or smaller sc pulley. the downside i would see would be intake air going right past the SC and possibly reversion upon shifting.

i dunno about bypassing it.

do they make boost controllers for superchargers...

maybe putting some kind of restriction so it wouldn't see full manifold pressure at 8-10 psi

cause the only thing i ever heard was the pulley swap

I have an HKS pulley on it already. Aslo I have the S/C on a programable TPS. Im running a stand-alone ECU.

well, then bypass away!
programmable TPS? never heard...
boost controller for superchargers? an SC12???

Its a ZEX programmable Throttle Positioning Sensor. It was the only way at the time for it to work. Its like a Nitrous hit everytime. Also it kinda gives the S/C a little bit longer life

weird. never heard. so, how is it better for the SC?

For the fact that its on demand. There when you need it. The computer doesnt control it. It doesnt engage off manifold pressure

ToyotaTechGeek · 03-02-2007, 03:18 PM

so, you are using this to engage the SC clutch??? i need to see this...
