Nev has said in the past that regular clutch parts, Barnett or stock, are ok until go beyond 170 RWHP. From others guys performance using just the drop in cams, power output is getting close to that mark. Personally, just heavy duty clutch parts from Barnett should be fine but won't last as long. My last set of Barnett clutch stuff before going supercharged only lasted me around 12000 miles or about one season. I'll be looking for Nev's lockup clutch in a little bit here.
ROB, you're gonna need something to retune the bike after the cams. Tuneboy preferably or PCIII if going with a custom dynotune. I'm sure Nev has some Tuneboy tunes for his stuff and I'm sure other Captains will share their tunes. Won't be hard to retune but you gotta add that cost in.
Nev, far as your lockup clutch kit goes. Here's what I want to do. I have a 2005 clutch with the weaker parts. When I get your lockup pressure plate, I want to upgrade my stock lifter piece and torque bearing to the newer post-2006 parts. Has anyone done this with your lockup or do you know if it is even possible? I think it will work but am worried about it fitting into the case because the newer machines have a different clutch cover number.
