Can anyone tell me if a DaVinci booster kit work with a Thunderjet already installed on a S&S E carb? And how it will effect horsepower. I'm running a 1977 Shovelhead 10:1 wiesco, crane 310B Grind w/ .525 lift, dual plugged heads with a single fire ignition, balanced and shaved flywheels and a Thunderheader exhaust.
no answer from me, but it ya go to his web site and ask the question i know he will respond....i have spoken to him personally and visited his shop...very nice and helpful guy.....
