I HAVE A 925 MACHZ RACE PORTED , 45.5 CARBS , VFORCE ,JAWS PIPES , 13.8CR . I cant seem to find a good setup that upshifts fast enough but doesnt suck the belt down if traction is broke slightly? Has anyone race a big bore and know how to get the power to the ground this is getting frustrating ? Ran a 180hp 800 last year went 9.99@127 this year 205-210hp went 9.91 @131 not much but seem to be worse for traction from the torque. Any input
