[QUOTE="Black02GT, post: 16475447, member: 23818"] So I'm having belt slip issues. Apparently 3.73 gears and 10.6:1 compression with a 2.8 upper on VMP is gaining RPM too fast for my belt to grab well. (or so my tuner is saying). Thinking of going 3.1 or 3.0 upper and a 4# lower but thinking of swapping out my standard upper idler to the Whipple tensioner. I can see the Whipple make have the advantage putting the wrap on the leading side of the pulley but curious of other's opinions before I just more on replacing one after market with another. Long story short dropping voltage and boost on the top end they're saying its the belt. Honestly I'm not entirely convinced it's not just alternator issues. I feel my setup SHOULD be losing boost in the upper RPMs thanks to big cams. Also I don't trust my J2 alternator right now. [/QUOTE]
