Vortech now sells a 10 rib 8" setup. The part number is 8E021-295. This is for a 10 rib 8"crank and a 2.95 pulley. This should get you the boost your looking for. They also make the kit in a 2.85 or 2.75 SC pulley configuration. Just change the last three number in the part number accordingly. The 2.95 is as large as they make in the 10 rib kits, I believe. They may make a 3.13 but I don't think so. So if the 2.95 is to small you may have to have a custom made 3.13 from ASP. Or IAN if he ever starts back up. You can bead blast the pullies if you need more grip. But I'd say you'd be fine to start as is and see how it goes.Quote:
