Here are the pics of the prototype. If there is any interest, this may be one of my next produts.

It hets pretty cold here in Michigan, its 26F right now and I do need a heater. I had a heater under my dash and I got tired of looking at it so I came up with this.

It uses the stuck heat/fan controls on the dash. The fan works in the usual way and the red heat director lever actuates the water control valve to control the temp of the heat exchanger.

Here is one of the heater control valve.
Does anyone know what these wires are for? The red is + and the 2 browns do not give me anything, + or -

Here is the pass side

As you can see, the original heat vents are plugged.

Mark,

Are the heater hoses routed through the original heater tubes back to the engine compartment?

Nice job.

NICE job Mark ... I'm envious !!!

Curious - what prompted you to grab water from the engine rather than the shorter run to the front radiator ???

Any chance you would allow me to include pix of the setup in my book '914-V8 Conversion Reference Manual' ??? With full credit, of course.

Again, great job ... hope you are willing to share with the V8 newbies.

Best ... ed.ducey@gmail.com

Andys-
Yes, my heater lines run inside the longs back to the engine

Propricer-
Feel free to use my stuf in your book. Check out my website listed in my signature for my gaues and stuff.

I do not tap off the lines to the radiator for a couple of reasons.
I like to keep water going through the engine when the t stat is closed. You may have noticed the return hole on the block where the water pump was is usually blocked by the new coolant line fittings. Keeping coolant flowing through the engine always helps to prevent cavitation and aids in expelling any air pockets.

My water pump has a provision for a heater suction side and I come off of the engine in the stock location on the manifold. I also have a small return line from the high side to the low side to keep some coolant flowing even when the t stat and heater control valve are closed.

I was thinking of making a kit for this conversion, I will test it next week when I get back home.

That is sweet, I will be needing one of those in mine, being old, I get cold easily and the defrost would be a plus too.

The brown wires are ground(s). Try to trace the sheath to locate the power source to the red wire. Tape that red terminal up so's you don't short out and/or blow the fuse (IMG:style_emoticons/default/sad.gif)

Nice job on the heater (IMG:style_emoticons/default/smile.gif) ... What did you use for the heat exchanger?

thanks for the input everyone.
If i were to offer these, would you want just the box with the core installed, or everything? (box, water control valve, j-pipe, etc?
Would you guys want a complete assembly or ship tours to me for modifications?

Thanks

Mark

I should have the Porschev valve covers in about 2 weeks

I would like to have everything (heater related) in the picture - minus the hoses. Nice work, keeps us from reinventing the wheel.

I would like one of everything as well. Let us know when you put something together and what the cost is. Looks really good and solves an important problem for some of us.

Yeah--where do you get the actual exchanger? Also--to do sourcing on the mystery wire, you COULD (your option--but exciting!) purposely short hot to ground just to see which fuse blows (maybe after first checking the red for current). Or, for the more prudent willing to spend more time on it, put a load into the line and check which fuse circuit shows current flow (what a drag).
Now about the origins of the exch. unit--new or recycled--if its not top secret?

I was wondering if oil could also be used for this as well, via an adaptor plate on the oil filter console?

oil in something like an oil cooler for aircooled engines that could be shut off or bypassed in the summer

The heat exchanger is new. It will use any liquid to heat it, so oil coild be used as well as coolant.
I have not had a chance to test it since my ignition cylinder broke and I still have the tank out to put my swaybar on. I should have it running and tested this weekend. The theory is sound, so it should work.

I think the Kit would consist of the heat exchanger in the air box, and the coolant control valve with optional j-pipe.
I would leave threaded fittings on the heat so that the customer could go to the hardware store and get the proper hose barbs for their particular size coolant lines.
I know Renegade's steup is $395, I plan on being less than half.

Add an AC evaporator, and I'll be interested too. (IMG:style_emoticons/default/biggrin.gif)
