What pulley when you were on the 6rib? Tuned by Lund? How much did it cost to switch to the 8rib? Is there really a difference other than the belt configuration? I’m running a non-griptec 3.4 now with no belt slip so I’m not seeing much of a reason to switch to a 8 rib.
My situation was somewhat similar to what your going through. I purchased my P1X 6rib kit used with a 3.75 pulley that made 11-12lbs. The kit had 47lb injectors along with a DW400 FP. Lund limited my rpms to max out at around 6800k because I would be at risk of running out of fuel at a higher...
Got a hell of a good deal on a clutch. Will get it put in hopefully within the next few days. Also got a set of BMR drag springs to help get rid of the camber from the Sportlines that’s currently on now.
Thanks and yeah it was the last track event in the area so I just wanted to see what would happen. Clutch is on the Christmas list or maybe Black Friday
Nov 8 : Took it to the track today with the mindset of trying not to break anything. My plan was to idle launch it and see what it would trap then once I got comfortable, give it alittle rpms and slip the clutch.
First pass. Idle launched it but missed 4th gear and coasted through the 1/4...
