Rapture Racing Carburetors

A guy a few weeks ago called me about a new set of 1050 hp style dominators he had built for his 462ci small block Ford that he had just freshened up. He was telling me he was having trouble when he would go up on the converter the engine would come up then just fall off and if he didn't get off the throttle the engine would go completely dead. He had got back with the company that had built them a month earlier and had no success. I told him to send them to me and let me see what I could do to them to solve the problem he is having. When I received them and took them apart and got them on the flow bench and seen some flow numbers I started to see some of the issues that were giving him some problems. The first major issue was that his booster signal was very low and without signal the engine can't make power. The next problem was one of the transfer slot had aluminum shavings caught up in it and was blocking the fuel. Then I noticed that the third circuit exit tubes that hang into the ventures were cut straight off. so I went back to the flow bench and check the signal on the stright cut tube and there was more of the issues he was having getting on the converter. So I went to the flow bench and worked with different style boosters to find what size worked best with the ventures and throttle bore. Then I removed the third circuit tubes from the ventures and installed the correct ones that give the best signal. I also removed the transfer slot access Plug to get the shavings out. I recalibrated all 3 circuits to get the correct fuel delivery threw out the rpm range of the engine. I also changed his pump arms and secondary linkage to increase the throttle response. Hopefully this my help someone that's having some issues like this guy was having. You can text or call me at 334.298.2220 or cell 706.888.6855 Thanks much

Well had a customer call early last week and was telling his carburetor did not want to and would not take the gas. Now this engine is running E85 fuel. I told him to send it to me and I'll take a look and see what's up with it. This is what I found.
