Worlds largest 914 Heat Exchanger Idea Options

[bandjoey]

Cold morning warm days. Fall in Texas. Pulled into work one morning and pulled my jacket out of the rear trunk. WoW. It was toasty warm in the trunk and got me to thinking.

It's just the largest Heat Exchanger you can ask for. What about running a hose with a small inline fan through the targa clip cups down to the cabin heat inlet and pulling heat from the rear trunk and into the cabin??

Your ideas on how to make this work please.

I agree with you Kent. As it is, the heating systems on air-cooled vehicles (at least Porsche & VW) leave a lot to be desired.

Aside from the heat exchanger arrangement (which could be deadly if there are any holes in the exhaust system), sucking 'fresh' air from the engine compartment isn't all that great either. Any oil seepage that gets cooked ends up in your lungs as well.

The flexible metal hose/ducting actually sounds like a viable alternative. Fresh air sucked from inside the passenger compartment ducted near the exhaust system and ducted through the rear trunk then back into the passenger compartment should eliminate most of the of the CO dangers.

Installing an electric heater would be a more preferable method and will provide you with fairly instant heat. You'd be wise to increase the alternator's amperage if you install a 300~600W ceramic-core heater.

A 300W heater will draw 23~25 amps, 600W will draw 45~50 amps ... pretty hard on the stock 55 amp alternator (IMG:style_emoticons/default/sad.gif)



For air conditioning, duct fresh air from the passenger compartment into an ice chest in the front trunk, then duct back into the passenger compartment. Refresh with new ice as needed.
