turning boost on and off

by **pro956** » Thu Apr 01, 2004 1:58 pm

a year or so ago i read about someone wiring up a switch to turn boost on and off to their s/c whenever they like (i think it was on camryman.org, but their site was down for a while and they changed forums and so on and so forth)

anyone know how someone would do this? if i remmember correctly it was fairly simple...

thanks

I would guess that they are using some pulley that can lock and unlock. I have seen these pulley work on buses. They engage, and the pulley is connected to the shaft, but then the shaft can be disengaged, and the pulley still spins. I don't know if they make pulleys that can do this small enough. The ones I saw were like 6-8 inches in diameter.

I tried to find my old posts on the subject without success. Anyway, if you have the EBC connected as per the instructions, for either manual or auto transmission, it is simple to turn off the supercharger. Wire a switch between the EBC output and ground. When the switch is open, the supercharger works normally. When it is closed, the supercharger is off.

Going from memory, I think that the EBC output is the red/yellow wire, if you are serious about doing this let me know and I will double check.

Which wire is it? I think i might do the same.

I thought EBC was only for auto in order to protect the tranny. I don't think manuals use them. I could be wrong.

I'm just curious. Why do you want to turn off the boost? You can keep the boost from kicking in simply by laying off the throttle a bit. Unless you just want to shut off the supercharger completely to prolong it's life.

manuals do use them. they use the ebc for cutting boost at redline.

yeah, you're right, i could lay off the boost
reasons:
-prolong it's life
-get the extra boost when i need/want it

-turn it off when my dad hops in the car (with its sound and all)
-and it would be kinda cool-- wouldn't it?
