carbureted turbo
Don't know if you got all of your carbureted turbo questions answered yet or not. A properly tuned blow through carb actually works quite well with turbo applications. We have just finished several dyno sessions on a 377cuin. sbc with both twin turbos and single 75mm, 80mm,95mm, and 101mm turbos. We were making over 1200 h.p. on 110 octane non intercooled at just over 20 lbs. of boost with a single blow through carb. You will need to lower the compression on your engine if you want to run any decent amount of boost. To answer your fuel pressure question you have to boost reference your regulator by adding a vacuum line to the top side of the regulator. You will need to add 1lb. of fuel pressure for every lb. of boost. If you need anything else, I will be glad to help.
