Patrick did an 830 cfm annular 4150 for my old 468, ran great right out of the box. When I had a new 502 built, I had him convert the carb into a 950 downleg booster. That carb was so far out of whack that it couldn't be adjusted to make it work when we dynoed the motor. A stock ProForm 950 that the dyno operator had lying around made 15 more hp without any tuning. The Pro Systems carb was way out of whack, 50 cc acc pumps w/ 45 squirters, Randy Malik says the metering blocks were way too big, I talked to Patrick about it with Patrick but couldn't get it to run right. It seemed so far off the mark that I didn't even feel it was worth the trouble to send it back to him. I got tired of fooling with it and gave up and bought a Quickfuel 950 from Lem and saw a big improvement in drivability with the new carb. The car starts much easier, seems to run cleaner and just all around runs better. Hit the wall and wrecked the car before I even tried to tune on the carb. I may just swap the metering blocks from the Quickfuel onto the ProSystems carb and see if it makes it run better. Patrick is great at setting up a carb, but he's not right every time!
