That was my idea as well for my MY83 OneTen. A DCDC Converter up to 16V should do and is very cheap on ebay. But since I retired I'm in the south most of the winter 😃 Quote Link to comment Share on other sites More sharing options...

What I found was when you increase the airflow, it generates so much additional turbulence in the pipework that the back pressure cancels out most of the gain. Even at 24V, I was probably only getting 25% more air out of the outlets. I liked the continuously variable control - but if I did it again, I'd stick to 12V. Quote Link to comment Share on other sites More sharing options...
Sigi_H Posted August 30, 2022 Share Posted August 30, 2022 I was also thinking about a additional (PC Fan iE) fan in the outlet at the footwell. There is plenty of space. Sucking mode to the outside means warm legs, blowing mode into the dash means more air for demisting the screen. But I don't know how they react to hot air.

Bowie69 Posted August 30, 2022 Share Posted August 30, 2022 PC fans are extremely weak by comparison to any automotive alternative, they are engineered to be as quiet as possible in most cases. Not worth it. 1 Quote Link to comment Share on other sites More sharing options...
