I have a 9lb pulley for the JRSC. Which pulley is it that I change? Anyone got pictures?

Uh oh... already got another one!

How big is the pulley? 3 , 3.4 ?

fengxzhang · 02-26-2003, 10:17 PM

I think is around 2

who did you get it from? endyn or motorvations?

the motorvations pulley goes on the blower side of the jackshaft. should be very easy to get off. in my case it was an absolutely nightmare because the woodruff key was bent, basically locking the pulley on. i had to nearly destroy it to remove it, with a specially modified gear puller.

i assume an endyn pulley would go in the same place as long as it's smaller than the stock ones. if it's LARGER than the stock ones, then it would replace the pulley on the other side of the jackshaft. if it's like 2x the size of the ones on the jackshaft, then it's a blower pulley and goes on the nose of the blower.

this is the motorvations 9psi pulley :

and this is where it goes

Ummm, I'm hoping that you have more than whats on your signature to help support the 9psi pulley. Just having the VAFC and stock JR EMS system, I don't think your engine will last more than a couple weeks.

it's designed for 6psi out of the box. manifold pressures are often shown to be somewhat higher due to restrictions in the valvetrain, header, exhaust, cat, etc.

What is the size of the stock pulley and the 9psi?

Girl n-a Lude · 03-08-2003, 12:35 AM

Hey guys I can't see pictures...maybe cuz I'm at work, but I was curious as to actual installation instructions...did yall have to remove the whole bracket to put this pulley on? I got charged for 3 hours of labor to install pulley. I don't know what yall mean by jackshaft. Is this the first pulley installed right onto side of supercharger?

geramy · 01-21-2011, 01:45 PM

3 hours is a lot for this if everything goes right. Now if they had any problems with removing the pulley (it was old and the pulley was "froze") then 3 hours would be about right.

ismael-robert · 01-21-2011, 05:28 PM

Well does whole bracket have to come off or can this all be done from top of vehicle by just taking off small belt and pulley?

geramy · 01-21-2011, 07:58 PM

yeah it can be done with the jackshaft still on the car.
