AIC Choices / Ideas
 

After viewing the photos from the "Red Witch" update and seeing his AIC it got me thinking again. I was planning on using a Ford AIC but the GM style is much smaller.

I assume the GM style has two lines just like the ford? I was going to run one line to the plenum, and the other inline, post air filter before the intercooler.

What have others done for this, I have bought the remote locater from Accufab the same place that I got my TB

Just trying to get some ideas and new leads.

Not sure what you're asking, there are normally no lines on the IAC. Now the remote one has to tie in with one line, somewhere that has intake vacuum or the throttle body itself, but no other lines.

Well the Ford one has two holes one that is placed before the throttle blade and one after it. In this picture it has there relocation adaptor, so you can mount the AIC away from the front of the car using two hoses.

This picture is hard to see but the AIC mounts on the side so no hoses are required.

If the GM unit only has one line then where does it get its air from? If it just gets it from the air around it then does that not matter that the air is not filtered?

Just like Ford to make it more difficult than it needs to be. The GM unit just has a cone-shaped pintle that opens/closes a single passage. One side of the passage is behind the throttle blade and the other side is in front of the blade.

On the remote GM units, they come with a tiny K&N style filter to filter air coming in, very trick and clean looking. There's a picture of one here from Kinsler, about halfway down the page on the right:

If you are talking about an IAC, all you need is a hole somewhere after your throttle plates. The system can then control how much air to bleed in during idle. Here's what mine looks like. It takes a standard GM IAC. Air enters through a copper filter (on the bottom) and flows past the cone shaped pintle that camcojb mentioned. The upper photo shows the holes in the throttle body, and the lower photo shows the IAC after it is installed. The brass unit next to it measures incoming air temperature (IAT). The throttle butterflys are to the left in the lower picture. The lever is the throttle lever.

i wish i had gone with a ford TB , i have the kinsler style iac and it looks horrible on my car.

The advantage of the Kinsler remote IAC is you can mount it anywhere, so when I needed one it was completely hidden. Doesn't look bad if you can't see it! Otherwise I always use a normal IAC, virtually every throttle blody has provision for one.

One other question. What throttle body are you running? I have the one you pictured above and you can use either a Ford or GM IAC. Neither has any external lines, at least the GM doesn't. Accufab offers a billet piece that bolts to the bottom of the throttle body to adapt either IAC to it. I chose GM as the BigStuff 3 uses GM sensors, as do most all the aftermarket EFI controllers.

If you are using the throttle body above you do not need a remote IAC. And it doesn't mount on the side, that's the TPS. The IAC is underneath.

Jody

true, its just i was told it had to go near the throttle opening to evenly distribute the air to all cylinders, not sure if thats is true though.

You are correct, but I am mounting mine upside down so then it would be on the top and I dont think that I am going to have the hood room. That is why i am using the remote style one. I have just put a plate over the area that the AIC would mount to.

I think I am going to order that one from Kinsler.
