Right now, I have a D&D clutch kit, VForce3 reeds, SW intake, stock gearing & standard track. I have the coupling blocks out, and the front shock almost all the way loose (about 1/4" threads). I get real good hole shots but am looking for a little more speed if it is even possible. Should I throw some 23/40's in or is 600 ft too short for them? What is everyone else running? How is the F7 matching up to zr8's, zr9's, RX1's, REV8's ect? I destroy all 700's and beat most 800's pretty good. Just wondering what setups everyone is running.
