Hi there!
Im seeking some help with my phazer. To start off its an 87 phazer with a psi pipe. It has a new red/pink primary spring and new blue/yel secondary with stock 47 degree helix in b1 preload per psi.ill get the exact number of the primary tonight. The main and primary nozzles are original. The pilots are 110 and mains 150. The sled runs excellent to 40 mph but about 6200 rpm. Then it feels like the secondary shifts out too quick and robs rpm and the speed increase is minimal. The clutch weights are stock 8vo that have been re bushed. The track spins freely in the air by hand so tension or undercarriage arent resisting movement. Should i change jets to 100/147.5? Compression is 120 psi in each cylinder. Any help is appreciated.

Thank you for your time
Brian
