I think that is going to be my next project . . . producing a crank position ring for the UR Pullies. . .

96-97 Models have a crank position sensor ring on pulley which the UR pulley does not have.

Installation is fairly basic. I would allow half a day for the installation. . . Its quite a bit of work, but nothing real hard.

Gains have not been quantified in the form of dyno testing. I would anticipate gains from 1HP to maybe 8HP if we are lucky, but these are just numbers based on the results of similarly sized motors.

The ring on the stock pully couldnt' be taken off and put on the new one? or is the ring molded into the pulley itself?

That has been done. . . by one person that I know of. The OE ring is press fit to OE pulley. Difficult to remove without tearing it up. You will need to have a machine shop prep the UR pulley to bolt the OE ring onto the UR ring. . . .

It can be done. I would recommend taking a UR pulley and an OE pulley and taking them to a machine shop and telling them what you want done. Orientation of the "missing tooth" is critical. It must be the same as the OE Pulley.

I just dremeled the CPS ring off my junkyard crank pulley and lined it up precisely on the UOR UDP. Then I attached it using aircraft adhesive (the same stuff they use to hold planes together- hey if it's good for Mach 3 and 10 g's, it's good enough for 200 kph and 1g, right?). Been working great for a couple of months now. Feels a bit peppier in the low end- well worth it!
HTH,
Bill
