Stick cars are just flat out hard to be consistent with. Especially with a non-slipper clutch. Your foot IS the converter. You might watch the crazy dudes that run Southeast Gasser class. All sticks, none dead hook. They MUST lift the tire by the rules, run a ton of gear and ride the wheel speed on out. 1/8 mile but if I had any money………..:):)
