Oh but buying supporting walmart is so much better.

*discreetly hides oil receipt from last week*

 

Make a better bottom mount that doesn't require rerouting heater lines.

I did gasp when I saw how much they wanted for that BMW part though.

 

Unpossible.

Were you really that surprised? The one in the BMW i'm working on at the shop has a tag on it still with that number plus a 1 in front of it. Its a pretty rare part and its BMW. I bet it works better than that walmart POS though. I dont know about you guys but I love going 120mph at the track with foggy windows.

 

these bilge fans move something like 250 CFM of air. A gutted car is already hot as hell, mines black, so even hotter. I don't think I'll really need a heating element to keep the windshield clear. I'll go for it and use a coat of rain-x if necessary. I'll post up results.

If it doesn't work, I'll hook it up to the intake and have a supercharger on demand

 

Out on track it clears up after a lap or so. But once I come in and park, it's pure fog within minutes. That's why I left the heater and blower in. Even with rain-x anti fog, fan, and heat, my first lap is nearly blind.

 

Funk dat. IMO this stuff is demanding/dangerous enough without having to deal with preventable visibility issues. I hope it is not raining at TWS next weekend. I already removed my blower, and the heater core is not plumbed

Edit: Check this out. This is a 360 Watt 12V hair dryer. It needs 40 amps of current so it would need some good wire, maybe run to the battery or the main fuse panel, but no big deal. Plus if it is overkill, a series resistor would chill it out a bit, pun intended. They say you 'need' the power strip, but I'll bet some good wiring would substitute for that, unless it is changing the voltage.

What if you could rig that up with a windshield wiper motor assembly to sweep the hot air back and forth under the dash. I'm only mostly kidding.

 

Tape it to the steering wheel. It will sweep every time you take a corner.

But to be clear, I am thinking one could rig it into some ducting like Oscar showed in his OP.

 

Oh totally. My buddy and I are battling this in his E30 racecar. The dash bar on the roll cage is making it all a huge ******* bitch though to route any ducting...

 

I don't recommend rain-x's antifog... I swear it makes it worse.

 

I left the stock defroster but pulled alll of the ac stuff. Connect the leftovers with a homemade cardboard/duct tape pipe.
