Just wanted to start a thread on what rpm everyone liked the best for the slp pipe. I know it's hard to compare trackspeed with one another because there are to many variables so I would just like to hear personal preference. I have ran my new 09 M8 162 with the slp pipe from 7800-8100 and see very little difference. Mine seems to pull real good at 7900rpm and that is at 9000ft. My current setup is 69.5g speedwerx lightip weights with a D&D 150/330 spring. I am still interested in trying the 68g weights with a lighter primary spring but not sure I will gain anything. Just wondering if anyone has played around with weights to find an even better setup. Are lighter weights and lighter springs better for cluthing efficiency, maybe geo could give some insight on this. I am just not hearing of anyone running 68 gram weights or a torsional kit that is getting better trackspeed than I have right now. I know clutching is a touchy thing but I like to constantly try to make mine better. As far as the slp pipe goes, I really like mine. It made the midrange and topend stronger and pulls harder.
