IAT sucks because it leans

IAT sucks because it leans out the engine, for this reason I would not do it.

The WAI was a snap took 5

The WAI was a snap took 5 minutes wish I would have done this earlier. 3" dryer hose fit perfectly on the airbox ran the tube between block and exhaust manifold. My manifold has a heat sheild which I hope will keep the cool air from getting in.
Had a few stops to make so took it for a spin the temps were steady between 114 and 125 and the ignition timing seemed normal. I'll have to see what the temps do at highway speeds.

See if I can post a

See if I can post a picture.



The end of the tube bends around 270 degrees and is between the block and the exhaust.

lol the alumminum foil is

lol the alumminum foil is the warm air intake... the aluminum is a good heat conductor yes?

my intake is plastic, plastic does not conduct heat as well!

I think he means on the not

I think he means on the not intake. I imagine it has something to do with the heated fuel lines.

The WAI hose does stay warm

The WAI hose does stay warm after shutdown but I don't have enought time on it to have a good feel for it yet. Yes, the foil cover the heated fuel line that runs on top of the radiator hose to help hold the heat in.

I tried the hose thing with

I tried the hose thing with the warm air. I saw a solid 1mpg increase on the freeway but the problem was it lowered my power. As long as you're always driving on level roads this mod will be okay. But if you ride up hills like I do most of the time the engine will downshift the tranny which in result will require more fuel.

But the foil on the fuel lines is clever, it will bump up the fuel temps and make for better atomization which will increase fuel economy.

I've got a lot of rolling

I've got a lot of rolling terrain so I'll see how it does. Our temps are alot higher down here also which should help with the IAT. I think I remember Compaq888 that you were have shifting problem until you reset the TCU, was it doing the downshifting before and after the reset?

Perhaps


Perhaps the key is "heat the fuel, cool the air" combo ???

I'm gonna try that...
