IAT relocation in my 2LT RS!

[scrming]

So last Wednesday with Scott from MRT's helps we started Scrming's Air Intake Experiment - Part I

So what is Part I? Part I is adding a stand alone IAT sensor and locating it in a spot that won't be so exposed to engine heat like the stock MAF/IAT sensor is.

So what's involved? Buying a IAT sensor and correct pig tail. Determine which two wires out of the five wires that go to the stock MAF/IAT sensor that are for the stock IAT. Cutting those wires and connecting the new pig tail. And finally, drilling and installing the new IAT sensor! Some quick snapshots:

Getting the wiring right!




New sensor in the air box lid:







Shop was 65 degrees but the stock IAT still read 97 degrees even though the car had been sitting for quite a while:



And new sensor is reading the air in the engine bay as 72 degrees.. which is more realistic... since the hood had been up for quite some time!




Everything all together!




So now your are asking... did it actually make a difference? Hmmmm... I'll let you decided... I took the car to the drag strip today... My best run has been 14.69 @ 94 MPH... Best 60' is 2.14...

Here is the slip from today... Left Lane - Car 260:




The air was in fact a bit better today than usual... but most importantly my IAT temps today were only 5 degrees above the outside air temp!! Typically the IAT temps are 15 to 20 degrees above the outside temp by the time I get the car staged! Looking at the data logs it looks like the car is running about 5 degrees more timing.... Needless to say i was geeked! LOL!

Nicely done, pretty nice results too

That's pretty cool!

[scrming]

thanks guys... yeah, i was surprised how well the V6 responded to this mod!

That is a very innovative mod - and I'm sure that'll turn into one of those "free power" modifications! Looks like it worked well for you!

I kinda did that when I went from NA to FI in my Cobalt...the MAF was originally in the intake before the airbox, so under the hood, on the passenger side. Now it is in the bumper cover on the driver side right above the cone filter

Ok... this part of my air intake experiment actually showed some promise on the dyno!

My driving observation has been the car feels more peppy, especially after the car has been driven and then parked for a while (Heat Soak!).

Here is the dyno sheet from today. You can see the nice gain in the low end torque. So from a stop, you can see that 1st gear would see a nice gain up to just before 5500 RPM... When the car shifts the RPMS drop down to 4400 RPM so the other gears see some gains too! So for $30 (or less) I think this experiment gets a thumbs up!

I think it's hilarious how it's almost fast enough to get a 4.6l Mustang already. Good work.

Nice work. Think I need to take a trip back to my hometown

decent gains, now if hptuners could crack the pcm and tuning would be available for those engines we would really see its potential.
