914 heater Options

[STP]

Has anyone improved upon the heating system of their 914?

Jc Whitney makes some heater blower kits for VWs Has anyone tried making these fit in their 914?

What about a higher torque motor?

Mine is on its way out and I've been searching for something like this and so far havn't come up with anything.

Thanks for your help

OMG!...I've just been searching for the same thing! My engine heater fan is putting up a horrible racket. Pelican tech forum had 2 suggestions for alternatives:
1.VW Turbo boost fans in the front compartment
2.Adding a second fan in the back with the original

This is great for increasing the volume,but I'm having trouble just finding a replacement fan/motor for the original...PP and AA both didn't have it on their online catalogue-are they that hard to find?

Any suggestions?Thanks! (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif)

Ha.

I live in colorado and I had to think long and hard about this one.

Bilge blowers.

They're about twenty bucks a pop. And they push A LOT of air. Hmmmmm. So replace the stupid interior fan with two of these.... And maybe mount another two on the heater boxes. And wire them to a speed controller inside....

BLAMMO! Instant heat.

An old web page entry I did on my first 914.

"I attempted to rebuild a heater blower motor without much success. Mechanically it was shot. You can see in the pictures that the choke coil from the power lead to the brush kept de-soldering itself when the windings smack the magnets due to the shoddy bushing in the bottom of the housing. Notice the grooves in the magnets. Replaced it with a motor from a 73 single blower unit. The mounting flange of the motor was too large to fit in the 74 double outlet housing. With a die grinder I removed approximately .050 all around the mounting hole in the housing. Sandblasted the mounting clamp. Works like a champ if not a tad weak. The motor is a smaller unit, but it beats freezing."

Thanks,mine is a '72-different heater motor again? AA had some sort of upgrade for '73-'74's motors to the "better" '75-'76 motors. I e-mailed them to see if this would work on mine.

[rhodyguy]

is aa's upgrade is the splitter that goes on the single outlet fan (it's shown in their old school paper catalog)? it just allows you to add a second hose that runs to the j-tube on the passenger side. the early fan is a dual outlet that mounts on the top of the fan shroud. if your passenger side j-tube has no fan hose, and is uncapped, a great portion of the heated air from the pass side he is pouring into the engine compartment.

I remember someone in the past was putting in 2 12V hair dryers to increase the heat in the car.

Is the problem volume of heat or just not hot enough? My 70 has no heater blower but everything else is hooked up. I get plenty of heat while I'm moving (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) During the winter here in Indiana when the roads are dry (and salt free) I drive all the time in 30 ish temps and I am plenty warm.

I would check and make sure your heating system is functioning properly before looking at doing any mods. Things I have found in the past were the flapper box was stuck closed blocking the flow of heat. I also found a critter made a nice little nest in the passenger side heater tube area, again blocking flow.

after ensuring that the complete heating system on your car is up to snuff, and you think you need more, go to www.barneysimportparts.com and look at their system.

Bilge blowers.

They're loud as heck, and they do not deal with hot air very well. I have heard reports from two people who used them in-line (after the exchangers, before the dash) and both of them had failures and didn't replace the blowers. Very loud, and not reliable when pushing very warm air.

You have to get the ones that shield the motor. They make some like that. I've got two in position to augment the heater boxes, since the other fan works well. But I might change over the other fan too. I really need the window defrosters for those really cold mornings.

I want heat too...

Hey DD,
that is fundamentally flawed how hey installed them. The set up we have in our cars draws air from the top on purpose. That way you are PUSHing air through the system and thus not sucking any CO or exhaust nasties into your system. This also shields the motor from extra heat.
Deffineitly DO NOT install your blower motor in a sucking capacity AFTER the heat exchangers. This could have very bad circumstances.

Just my $.02.

[alpha434]

Right. Thats what I did. And if I redo the primary fan, then I'll mount the blowers right against the bulkhead in that corner, as far from the heat source as possible.

I like this one......

[Cap'n Krusty]

This whole discussion is bogus. Maintained and adjusted PROPERLY, a stock 914 heater system soon requires that you roll down the windows to keep the cabin temps in the "comfort zone". If it'll heat a VW bus, it'll sure heat a teener. I've driven in mid 30s weather with the top off, and not felt cold. You need to put your energies into fixing what you have, not throwing money at stuff you don't need ........................................... The Cap'n

If there's not enough -heat-, then you've got other problems. If there's not enough air flowing, then chances are that either your existing fan is not working, or there is a break or blockage in the either the heat exhanger or heater tubes. No need to bodge it, the stock system works pretty well.

The factory heater system was plenty good to heat my 914 for those frosty morning drives down from the mountains in the winter...

Agreed. Mine will roast me out in freezing temperatures. The factory fan will put out plenty of airflow if it is in good working order. Fix what you have.

The only reason to go away from the stock heating system is if you run headers with no HEs. Then gasoline fueled makes sense to me since you have it on board and electric is not practical.

that URL was from an ad in an old hotvws. sorry i made ya type barney's import parts into a seach engine (IMG:http://www.914world.com/bbs2/html/emoticons/spank.gif) . i too think it's misspent money. got headers? wear goretex and gloves. my heat system is tight enough that i don't need the aux fan.
