Hello fellow builders,
I am at the point of ordering my FWF-kit. Also I am in touch with Larry Vetterman about the supply of an exhaust system with mufflers (noise restrictions in Europe!). From Larry I learned that the mufflers have to be air cooled. The hot air from one of the mufflers is also used for cabin heat.
I have already ordered the cold/hot heater valve from Vans, instead of the standard heat-box, because I like the additional comfort during the hotter season, being able to have a cold air flow underneath the instrument panel, to keep the feet/legs cool(er).
Since the mufflers need a constant flow of air, they should not be shut off (as you would with the hot/cold heater valve, when switching to cold air, or when closing the valve completely).
Larry tells me to use the ?Standard? heat box, but this will let the hot air flow into the engine compartment, when cabin heat is not required and unnecissarily heat up the firewall (certainly arround the heater box area). Apparently the air from the mufflers is really hot! Obviously with the standard heater valve the cold air is not available either, which makes the "hot" situation worse.
How have others done this? Or has anybody seen an installation like this?
Regards, Tonny.
