4agze --> SuperCharger will not power up/ Boost

found this info on the board:
Re: 4agze Super Charger Clutch

--------------------------------------------------------------------------------

A common fault with the 4agze motor is the relay for the clutch that fails, have you followed the wiring and bridged out the clutch to see if it is working?
By "manually triggering" the s/c it means to put 12v over the coil to activate the clutch, this will tell u if it is getting a 12v from the s/c relay or not.


and also this info:
-------------------------------------------------------------------------------------
S/C is self contained, it uses a special oil from toyota, though others use Mobil 1 or other very thin oil in it. It's capacity is 130ml. It seems to simply oil the gears which mesh the rotors together... it's supposed to be clear.

but is everyone in agreeance that its cool for me to just weld up the clutch and have the sc running all the time??? will this cause me any long term issues???


other than going through LOTS of petrol... which doesnt bother me.. its only a track car anyway...
If it's a track car, there's a good chance that the supercharger is never disengaged, [u:37dd3bf9a9]I think it's 3 or 5 seconds after you lift off before the computer disengages the clutch[/u:37dd3bf9a9], and I doubt you'd get that on the track. Maybe hook a little LED or something up to the trigger for the SC clutch to see how much it's acutally off. Maybe welding it is an option...but if you're going to do that, I'd machine a smaller SC pulley up so you get bigger boost without the problems of a bigger crank pulley...



So i can check the puley by manually trigger, and try to find the relay

I will update when there is more info!

Banpei, thanks!
