Mine was setup with a 110 jet in spray bar fed off of water distribution manifold, another line off of manifold to RRP water box with Jet Works FCV. Setup was soft and slow revving. Cut water to the water box, still sucked. Switched setup to dry with 80 jet in stinger and no water to water box, straight rips now. Still adjusting FCV to stinger but setup revs quickly and delivers linear power. Using PF sand filter. Now, water to the exhaust when wet was straight from pump so it may act differently running hot water from cylinder, hope this helps and your setup works for you. Engine is 10 mil DASA 900 with 50mm carbs and MSD T/L if that matters to ya. Have fun
