Adding Heat to the Clown Car Options

[davebrossi]

Apologies for going quiet for months, but I'd burnt out trying to solve the overheat issue on the clown car. Turns out at 5k miles, the fan belt was stretched/heat damaged. no more overheating. (IMG:style_emoticons/default/beerchug.gif)

Now, in case you're wondering about the whole title/point of this thread, I have been bitten by the bug that whispers "what you really need is heating!" as I live in Idaho where they don't salt the roads, but where it's below freezing much of the year.

I'll be searching/educating myself in exactly what I need to do, but in the meantime I thought I'd offer a window/way for people to follow along in the adventure.

To recap; The Clown Car has a 3.2 from an 87 911, straight headers (which -will- be available once I'm done, hint hint) and it uses a custom engine mount/tin from Rich Johnson. I have opted to go for as close to a stock heat exchanger system as possible over an aux gas heater due to concerns over my ability to cause vehicles to catch fire (I lost an 81 Vanagon to fire.)

Based on what I've been able to piece together thus far, in addition to custom headers that mate up to the 3.2's larger diameter exhaust ports, I will need;
-flapper valves (I'm assuming the 'custom' part of the headers means I can utilize standard 914 flapper box assemblies.)
-aircraft grade fresh air ducting from flapper boxes to longitudinals
-the 'mystery manifold' that exits the bottom of the engine tin and goes to both exhaust headers, this part I'm still working through. (IMG:style_emoticons/default/chair.gif)

On the other side of the engine tin the standard 3.2 has a 'port' of sorts on one side of the fan shroud (currently capped,) a duct that terminates on an aux blower (still have the wiring harness on the motor), then duct work from the aux blower to the engine tin terminating just next to the distributor cap. There should be some form of flange in the tin that mates the upper and lower together.

I know because the engine bay is not the 3.2's native land there will be'customization' (IMG:style_emoticons/default/sawzall-smiley.gif) (to be fair I don't like customization, that's how you get terms like Mississippi'd or 'mickey mouse'd'

I hope to photograph the process here, and while advice is always appreciated, I -can- use the google search function too, so I'll be looking at everything else in the meantime.

You’ll love the amount of heat you’ll get through the heat exchangers with the 3.2engine. Backdating to the older style heat ducts should move as much air as you want, and you can fry yourself from all the heat that flows through the exchangers. Ben does amazing work!
