Google Omega temperature products. Get a handheld dual input "K" meter ~$150(comes with a few .006" beaded thermocouples) also get a couple "K" 10' extensions. Insert the beaded thermocouples into the airstream under hose joints etc. Once you look at your charge temps you can used the gear for lots of other interesting temp measurements.

The market is completely devoid of a true bolt-on quality aftermarket intercooler for our cars.
I looked up the A/Spruce unit, thanks for the tip!

You might also look at pressure drop to complete the picture.

Thanks Todd, I do plan on gathering as much data as possible in the beginning I said putting this turbo on a 2.7 is all about risk and info gathering, just a note I got the tail sold despite the canuck that stiffed me.

I am running a Davtron as well with my 965 intercooler. The temps will vary with ambient air temp, boost, turbo, intercooler, and length of time on boost. Any turbo and intercooler combo can see over 100 degrees depending on the factors I listed. Typically I see close to ambient temps if only doing short pulls but on a low speed road course the temps will rise with heat soak and I have seen high temps well over a 100 degrees. Happy thanksgiving!

Where do you plumb in the probes? Will I need to drill and tap or add bosses?

It will be fairly easy I think you should be able to add a fitting to the inlet and outlet plenums and that will give you the readings you need.

You will just need to drill. They are thermal couplings so no tapping. I put them on the back of both ends of the intercooler so they can't be seen and ran a wire loom up to the dash to keep it clean.

If evaluating different inter-coolers, I suspect pressure drop across the core at a given CFM or HP is another point of interest.

I would think getting a gauge that you could mount in the car would not be accurate enough for measureing the drop across the IC maybe inches of mercury DP

I've done it with normal MAP sensors. The one at the manifold connected to the ECU as normal and the dyno MAP sensor connected at the supercharger output manifold before the intercooler. Log both and compare.

I don't want to drill into the intercoolers. Sounds like drilling the stock intercooler up-pipe and the intake manifold is the way to go.
If you don't tap the holes how do the probes stay in place? Anyone have a picture of these probes? I didn't see any on the site I visited.

Looks like the best place would be the intercooler with lots of locktite.

Thank you for the link. How quickly do these probes react? If it takes 60 seconds to stabilize temp it is no good for the intended application.

The Davtron is instant.

when i recorded my temps it was in the hi 80*'s outside and i had been doing a lot of driving and idling. On the first 3 gear pull the temps were in the mid 120*'s it wasn't untill the second 3 gear pull that the temps got to 134*. I would suspect on a road coarse the temps would get above 150*. Keep in mind my temp sensor is in the intake manifold, not the pipe or intercooler so some engine heat is transfered. The best comparison would be "whats the inlet temp while cruising vs. WOT?"

mine was 95* cruise - 134* WOT (15psi) anyone else care to share?
