Getting ready for NH race what to do for a windshield defogger?
We ran NH last year and as most know the weather can be cold and wet. With the windshield fogging up on Saturday it was just dangers!!
I still have the heater core in the Beetle so we will run the hoses to get it to work so I think we will be OK.
But I had been thinking for a simple fix for most would be to make some kind of copper tube to run the engine coolant through it, long the base of the windshield. But cover it with some of that aluminum defroster flex tubing with some slots and add a blower like a hair drier at one end.
Any thoughts on this or what others have dome in the past that worked.

We use a 12V fan heater works ok where it is pointed.


If we did more wet races I'd consider one of these....

Didn't you formerly do rag on a stick?

We use rain-X on the outside AND inside of windshield, and then keep a window washing stick with terry cloth pad in the car for the driver. The fan/heat idea sounds great, but it seemed to us that conditions changed quickly in certain areas of the track or if you slowed under a caution, and it was beneficial for the driver to be able to quickly wipe specific areas of the windshield immediately...

Keeping the stock heater box, blower, dash, and ducting worked amazingly well for us. Just throw on defrost full speed and crystal clear windshield. Air moving over the glass will always help, even when you coat it in every chemical under the sun.

One of the new england truck teams installed a defroster matrix on the inside of their windshield and says that works great too.

Rag on stick is a good back up plan as long as the track has long straights.

Fog-x works but read the instructions, once your screen is wet you are boned.

Re: Getting ready for NH race what to do for a windshield defogger?

seems to be highly dependent on what your airflow is like through your interior.     With our homebrew mid-engine, running a OEM-style heater would be difficult with the rules to double-wall all coolant plumbing in the cockpit.    We've had various fans, tried multiple chemicals, and have not found an acceptable solution yet.

YMMV
