So I'm interested to know what increase in AIT temps you see when completing a full pull through a gear?

What type of system you are running would be also helpful...eg: CT, SOS with aftercooler or intercooler, turbo.. Etc

EOE

NOVI1000 @ 13psi
I relocated my AIT sensor to Comptech aftercooler and I have no idea why I've waited so long to do it.
My idle/traffic temps would be 145-165f and as I would go Wide Open Throttle they would drop down to 120-130f.

Outside temps:
70F

Heavy Heat-Soak at Idle and stationary for 30+ minutes:
AIT Sensor in Manifold:155f - 165f
AIT Sensor in Aftercooler: 95f - 110f

Heavy Heat-Soak in Stop&Go Traffic:
AIT Sensor in Manifold: 145 - 160f
AIT Sensor in Aftercooler: 90f - 100f

65mph Cruise:
AIT Sensor in Manifold: 120f - 135f
AIT Sensor in Aftercooler: 85f - 92f

*******************
20MPH - 100MPH WOT on-ramp pull = 2nd, 3rd, 4th gear pull all the way to 8200RPM:
AIT Sensor in Manifold:
145f - 135f - 130f - 127F and stationary, then starts to creep up through the 5th gear.
As you go partial throttle and RPMs drop, throttle plate closes, Intake temps skyrocket to 145f-155f as AIT sensor is being heat-soaked. As you go partial throttle temps level out again at a steady and toasty 135f-145f

AIT Sensor in Aftercooler:
90f - 110f - 120f - 127F and stationary, then start to creep up through the 5th gear.
As you go partial throttle and RPMs drop, blower charge starts to cool and temps slowly drop back to 90f



Verdict? Well, WOT peak rpm temps didn't change (Obviously). Nothing is actually running cooler, it's just that the sensor is no longer heat-soaked. The car is more responsive under partial throttle. Stop and go driving is improved. Also, if you have AIT readout you can watch temps climb with boost and then decrease just as they should be.

Or you can keep this sensor in the intake manifold and watch your ECU go full retard and pull timing as it has no idea wtf is going on and why in the world air temps are liquid lava hot.

Two for relocating my sensor from Manifold to just before the TB on the After-cooler.

Thanks for that! Tells me exactly what I wanted to know! I've just searched and found the thread regarding relocating the sensor.

You got a picture of your install?

Does the OEM wiring reach the new location?

Even after a full session on track I never see IATs higher than 114F. PTUNING turbo kit with front mount intercooler. Sensor is mounted in intercooler piping about 6 inches from the throttle body.

I'm running the Novi 1200 but with the Comptech aftercooler and the IAT sensor located in the air port just before the throttle body (no issues with the sensor/wiring reaching this location).

In normal driving here in Texas with 100*F ambient temps, the sensor is reading about 15-20*F above ambient. If sitting (not moving), the temps will slowly climb and settle about 30*F above ambient, but once moving will quickly drop to the temps above.

During my last track day with ambient temps at 95*F the car at its hottest was reading 135*F right before the cool down lap (20 minute sessions), but this was with me not pushing the car very hard (I'm a novice) and shifting a 7k RPM.

Forgot to mention that this is with the larger SoS Racing Heat Exchanger and the Cobra Bosch Water pump. Running straight distilled water with a capful of Watter Wetter.

Id like clarification on this as well, even for N/A relocating to intake tube. I know the stock wiring is too short, and am concerned that lengthening it may? skew the read to the ECU. This sensor is direct correlation to the timing map, so I don't want to create a situation where the car may be prone to detonation.

In what year vehicles is it too short? In my 2006 the sensor and related wiring reaches the air pump port on the aftercooler (just forward of the tb) just fine with no lengthening or changes to the sensor. This is where Comptech recommends the IAT sensor be placed for the 06+ cars (as they don't use the port for the air pump).

Is there a picture in the CT manual? I would like to see one fitted on the CT AC?
