Help with Computec SuperCharger Pulley

[NSXDOC]

I just posted this in the general forum with no responses; my question really belongs here...

The company called Computec discontinued their whipple stlye supercharger.
This is the reposnce from CT Enginering:
"We stopped using the Whipple supercharger about 7 years ago. We lost a lot of information when Comptech closed. After talking to the guys in the shop the only question I have an answer to is that our pulleys bolt on. They are not keyed and not press fit. I don’t have access to the dimensions that you requested. You can probably measure the pulley on your car or send it to Pulleyboys and have them copy it."

Does anyone know either the original 6psi boost dimensions or the dimensions (schematic would be perfect) for the 9psi pulley. The above mentioned machinists "Pulleyboys" can build it if I can find the dimensions...

Does anyone have the smaller 9psi pulley for the same Computec Supercharger?

I Need to replace the belt on the Supercharge anyway; so I was interested in going down in pulley size.
Can anyone give me and estimate something a little smaller than the 6PSi boost pulley?

If you call ct engineering they can tell you.

See the link below:

You will most likely need other support hardware for high boost.

Science of Speed has this on the web site, but they have none in stock
"enpp-1031 high boost pulley for Whipple based Comptech Supercharger, 86mm
$98.00"
They referred me to CT Engineering who no longer make the pulley. (they do not have a schematic either)
Ct Engineering referred me to Pulley boys who could make it if I had a "to size drawing" or an example for them. I don't really want to have the down time to take off and send them my regular pulley...
Does anyone have one for sale?

I am getting one sent from WHRD in Australia.
When it gets here I can take some measurements and pic if that would help anyone for future...
Received today and took measurements. I do not have a micrometer so these are the best I could get:
out side =90mm
inside inside the groves =80mm
inside where the belt would be= 84mm

I am ready for the install. I need to find someone who would tinker with a couple cooling ideas I have. I need to install the new pulley and then dyno /tune it. I live in CO anyone know someone who has experience with CTSC here in Colorado?
