My car ran 9.44 all out with a 200 cfm larger card for the Unleashed races this year. I don't have a throttle control that controls the throttle. My foot is against the throttle stop all the way down the track. The throttle stop is a bolt that is under the throttle pedal that prevents you from tearing the throttle ball off the carb. I believe the throttle stop is required by NHRA under the pedal.
