I'm running a 98 Javelin 400sd with a 2006 E-tec 225 HO. I am currently running a 28 Raker2. 79.5 mph,6100 rpms, 17-19 water pressure, 2 3/4 below pad. The hole shot is not that great. I have a 27 Tempest that I'm going to try but I would really like to get those rpm's down without losing speed. I figured I would try the Tempest to see if I would get a better hole shot since you can play with the pvs holes. Then if all goes well on holeshot try to find a 29. What do you guys think?
