I'm going to have some pulley's custom made for the whipple, and was just wondering if there would be any interest from the whipple guys on here. These will be 6 rib, ultra-grip pulleys from Reichard Racing. If you are interested, let me know, and we'll get the order started. The smallest that whipple makes is a 3.5" I plan on getting a 3" pulley, but I might be open to a couple other sizes. Who said boost is addictive?
