I have a 2006 whipple HO supercharged GT (first gen whipple). I scored a 3.25" pulley for dirt cheap. Anyone know what size belt (part number would be excellent) I would need to run the pulley? I have a 3.375" 10 lb. pulley on right now. Before anyone asks: Yes, I will be dyno-tuning for the new pulley. Thanks guys.

Its gonna be the gates K081223 1-3/32" 122-3/4" or 26mmx3117 mm....I have a new one sitting right next to my computer. You could also try the Goodyear gaterback..since your in New Orleans your short drive from Justin at VMP tuning..dude is money....

You're the man. Are you running the 3.25" pulley on a first gen whipple H.O. as well?

VMP isn't as close as the map may make it look. It's about 11 hours away (I typically put less than 3,000 miles a year on my car). I'll probably get the tune done at RWTD in Mobile, Alabama. They've been tuning boosted mod motors since the supercharged lightning first came out.

Nine is upgrading! nice...let us know what she puts down on the dyno!

Hell yeah I do! My track tune is already at 488 rwhp and I can't wait to put down an honest 500 rwhp. (My street tune is a more conservative 465 rwhp)

It will be a couple of months at least. My son (first child) is due August 31st, so I won't be doing any traveling or work on the car until at least October. I will be sure to update when the time comes!
