Quick question for you speed density guys. I've been researching a lot about this but can't find a solid enough answer. Where is the best place to mount the AIT sensor? From what I can see it looks like the UICP or the intake manifold will be the best place?

Thanks in advance

 

If you insist on running it, 6-8" from the throttle body. Really, its not needed and I wouldnt run it.

 

So you don't need an AIT sensor to run speed densty?! A standard UICP with no AIT bung will work?!

 

Some tuners are using fuel temp with good results.

Could you please elaborate on this a little more? I'm just a little confused and don't want to make the wrong purchase as I see some intakes have the bung, and some don't.

And if the AIT sensor is not needed, then what else would I need besides the Omni 4 bar? (which I have already).

Thanks

 

Its not needed. The ECU can be set to use the fuel temp sensor instead. Its not a "real" IAT reading, but it works.

here is an older thread from JB

Other than the MAP sensor all you need is a speed density intake which is around 150 -200 dollars if I remember correctly. And obviously a Speed Density tune. That's pretty much it.

 

Awesome! I'm going to read through this now.. good thing I have a desk job

 

Yea I'm looking at intakes now and I see some that are just a regular intake pipe (with no bungs or nipples welded on), and others have a brass looking nipple on it already. I'm guessing I would just need the regular one without any nipples or bungs

 

The nipple on the intake is for a vacuum line that runs from your valve cover to the intake. Its part of the PVC. The other bung would be for your DV to recirculate but since youll be going with SD you wont need that.

 

There's are the two i've been looking at.

This one has no brass nipple: STM Tuned 4in Speed Density Intake

This one has a brass nipple for a PCV: ETS 4in Speed Density Intake

Not really sure which one I should go with?!?!?!?!

 

I guess I will need the intake without anything on it then.. since my PCV runs to a catch can setup.

 

You should still utilize the nipple on the intake to help alleviate crankcase pressure is it pulls vacuum from the turbo. Just put the catch can inline to help trap the oil vapors.

 

The only bad part in doing that is when its 25 degree's outside the a/f is SUPER rich at idle is super lean during 90 degree weather if you tuned in 50-65 degree weather. Other then that its good.

 

Do you mean idle even when the engine has warmed up, or just at cold starts?
