Warm air intake
 

I put a warm Air intake... fully insulated the tubing from near the exhaust manifold all the way to the intake manifold. I even insulated the filter housing so the warm air isn't cooled along the way to the intake. This has made the warm air intake much more effective than without being insulated and my mpg's have gone up significantly for winter mpg's. I'm getting much closer to Summer MPG's! Typical Winter economy was 44mpg and Summer was 54MPG.
Now my Winter has been around 48-50MPG since mod with insulation.
BTW, I used insulation that is high temp... used for insulating your home water heater. Have R value of 7 I believe and 250 degree rating. As long as you keep it 6" away from the exhaust manifold, you are golden.

That's impressive! Got any pics of your setup? :thumbup:

I haven't figured out how to put pics in here... I emailed the contact email with zero response about a week ago.

Look in my album that's in my profile. I have a pic there if you have access to it.

Have you seen this thread yet? http://ecomodder.com/forum/showthrea...der-18279.html

I use Photobucket, even though they keep making the interface more cumbersome.

Oh wow, that's a lot more insulation than I imagined. Ever have any issues with it coming loose, or pinking from having such warm intake air?

Here's another tip for later: if you right-click on your picture in the gallery and choose "Copy image address", it'll put a direct link to that picture on your clipboard. You can paste that into a thread reply, add an [IMG] in front and [/IMG] at the end to get this. :thumbup:

Nope... I've had it in for a few weeks or so now and it's my daily driver. I don't see any signs of discoloration from the heat. I'm sure if I had it on the exhaust manifold it would be a different story. It is rated at 250 degrees.

Interesting. But do you need to remove it once winter is over?

I will leave it on all year. I may have to pull the tubing away from the exhaust manifold in the Summer, but will cross that bridge when I get there. Depends on how it runs and fuel economy with it taking in that hot air in the Summer.

Have you ever seen the carburettor heating system of some older light aircraft? Since its working principle is similar, that might become a source of inspiration in case you decide to make your WAI adjustable on-the-fly for a better all-year-round operation. Is there any space where you could fit an air-box that would allow you to blend the heated air with a colder airflow?
