I believe they are from either a 2.3 or 3.3. They are black in color, 8 rib and are machined for a keyed shaft. Excellent condition. $175 shipped to the U.S.. Will separate for $100 each plus shipping.

ttt.....offers?

I still have these

Prob procharger pulleys .i know the 2.1 and 2.3 used a hub and 4 allen bolts with some different offsets on the ones ive seen .

Pretty sure they are Whipple and still available.

If you can PM me a picture. Thanks

If they are for 3.3 s for sure I can use them ,let me know

Please send email info for pics.

After further review, I believe they are the standard D series for a Procharger.

that would make a hell of a lotof boost on a whipple, my 4.250 makes 10 psi
