I've been running my car in the 7.10 index .500 pro tree races and have been struggling with lights. I've tried a bunch of different combo for shock/air/startling line rpm settings. My car will typically run 6.70s all out so I have a ET Genie restrictor plate on the car and have it screwed in 15 turns if memory serves me correctly. Since I have it screwed in so much the throttle response is slowed thus causing my slow reactions. On a 2 bbl my car will usually run 7.12-7.15. My thought it to run the car on a 2 bbl unrestricted as that should be a better throttle response, but I need a way to make it that .05 quicker as I can't afford to give up that ET. Car has a Proform 850 carb and I know they make an adjustable secondary linkage kit, but would this allow me to adjust so the secondaries only open a small amount? I'm thinking that would be the easiest way if I could somehow get it so that secondaries just barely open. If not maybe I can fab up my own linkage. I know a shorter front tire or deep staging would change things as well, but trying to avoid those options if I can.
