So I'm building an intake manifold to boost my kart.. in trying to understand how the wax valve works. When looking at the throttle bodies there are small chambers in the middle where the plungers are for the wax valve. I'm looking to make a plate that seals the to of the throttle bodies off and attach to a manifold. Do I need to tap this chambers in to the actual ports? Or not... out a small channel for them to flow to the ports??
