Fan housing blockoff, no heat Options

[MattR]

From what I understand of the 914 heating system, the fan housing outlets have to be blocked off if I'm not running heat. Can anyone give suggestions on how to block these off? I could weld them up, but Im not sure about the material, and I'd like to be able to seperate the fan housing without grinding and rewelding.

See if you can find a late 2.0L VW bus fan housing, it will have a VW and OOOO (audi) on the casting. They have no lower ducts and a larger (deeper) housing. Jake told me that this housing blows about 20%, if I remember correctly, more air over the oil cooler. Since it has a smooth path inside I don't see why you couldn't afix a piece of aluminum inside. BTW we used this set-up on my son's E production 914 for years and it cooled fine. OH! I forgot the alternator will not line up as the bus used a squirl cage blower on the end of the alternator as a heater fan. The race car did not use an atlernator!
