Finally got a chance to run the f7 with the restrictor installed. I have the adjustable type with the gage. I set it for 30 - 31 at WFO. It has a unacceptable lag when going on and off the gas. It runs ok once the fuel starts flowing. I have v force reeds and a BIkeman can on it. I wonder if the reeds need more fuel ? I put the stock fuel line back on an it runs fine. Any ideas ? Would the jet type be better ?

Stock fuel pressure is 40-45 psi. At WOT for trailsafe conditions no more than 3-4 PSI below Idle Pressure! You can go 5-8 for 600 to 1000 feet lake races! Verify your machines and gauge readings at idle and reduce from that number! :div20:
