JS Pulley Identification

95_XR7

Registered User
I picked up a few with a project car awhile back. Currently doing some work on the black '95 so I need to know which one to swap onto it.

The parts say:

SCI R1001
&
SCI R1050

I was told one was 5% and one was 10%.

Any help would be appreciated.

I must say that those are great pullies!!!

R1001: is an all stock diameter pulley, just a lot lighter than the steel ford pulley.

R1050: is a 5% overdrive,

I was the SCI, if you want/need any other info I will help out with what I can. Are they both annodized clear? Or no coating on them?

Much appreciate with the rather quick response Ryan.
So the R1001 is basically the same Pulley I have on my '95 currently.
Now, on top of the R1050, I went out to the actual project car and took a look at the pulleys installed.

On the JS the pulley is etched with SCI Eliminator 1000. The water pump pulley says R1005 and the alternator says R1004.

Every pulley is clear anodized silver, except for the R1001 which is show polished.

The Eliminator pulley is only for use on AR kits, it will not work properly for an M90. It is a 10% OD pulley.

I just ran across a set of clear anodized.

#'s are R1001, 1004, 1005, 1006

These would be stock replacement for factory pieces.

Did you also make a press on blower hub and pulley.

3 Allens on the outside and marked E 7.5%
