One heat muff to supply the front only cuts the heat to the firewall and so the tunnel by half. (the firewall vent for the rear can be permanently sealed off and the air out of the unused heat muff can be dumped down, or that heat muff can be removed) For the front Using a T fitting incorporating a butterfly valve (available from Spruce) the heater air from the heat muff can be diverted via a scat down toward the bottom cowl instead of blasting away at the firewall all the time the heater is not required. (which of course includes Summer) Only two push pull controls are still required, one to control the T fitting and one at the firewall valve. Using this solution the firewall valve really only needs to be full open, heater on, or fully closed heater off, this reduces the likely introduction of unwanted fumes entering the cabin with a partly opened firewall valve, heat is regulated via the T fitting out of the heat muff, the heated air is still full flowing through the heat muff so no abnormal build up of heat by restriction. Just my solution which has kept the tunnel cool.

Its easy to remove when you want full flow.
