so I barrowed a 20k dollar toy from work yesterday for my dyno day. The IR camera doesn't have a video function, so I had to point the IR camera at my car and then record the screen with my iPhail...

notice the temperature range bar on the right changes as the temp goes up. The temp readout in the upper right corner is the temp at the crosshairs in the middle.

after seeing this, I'd say the stock intercooler isn't to bad. Most of it gets really hot during the pull, but in one of the vids, I kept the crosshairs near the discharge pipe of the intercooler and the temp only got upto a bit over 50 degrees. but then again, this is only one pull. I'd imagine if you stay at high rpm's for a few gears the temp goes up...

the car is a bone stock 2011 GSR with about 2400 miles on the clock. put down 268 whp with SAE correction. The guys at Drift Office couldn't get an rpm pick up, so no tq. On a side note, can someone could tell me where to pull the rpm signal from for a DynoJet for the next time I go?

First time I have seen anything like this, thanks! When you upgrade to the AMS IC, do it again

 

Wow! I wonder how much that camera costs?

 

I doubt mine is gonna be an AMS intercooler, to expensive for me...

As for the cost of the IR camera, that one is 20k. There are cheaper ones also, my company also has a 7k one. Same thing except half the resolution

 

Very cool info, thanks for posting! After seeing this I am glad I got an aftermarket FMIC on my stock turbo setup.

 

That looks pretty cool.
I would be awesome to see some test with different intercoolers

Tho you got to remember that your intercooler cools by having cool air flowing through it. If there is not air flow, its just going to heat soak. I am not too sure if you did have a fan blowing on the intercooler or not.

You are also testing radiation heat energy.
I am not too sure if a measurement of radiant heat would be a sufficient test to prove an intercooler is better than the other one. This is becasue an intercooler is design to radiate heat outward to the atmosphere, which enables to cool air inside the intercooler.

A more accurate test would be testing conduction heat transfer using thermal couples from the inlet end of the intercooler versus the outlet end.

 

yes, there was a fan on the car, i was standing right next to it

I was more measuring the heatsoak of the intercooler than the air inside. The IR camera see's the temp of surface objects, not inside. so I know the temp of the air inside is different than the surface temp of the intercooler, but it still gives you a decent idea of how the air is cooled. In one of the vids I had the crosshair right near the exit of the intercooler, and the temp there stayed in the 50's. so the stock intercooler did a decent job cooling the air charge in a one gear pull... considering it was over 130 degree's at the intercooler entrance...

 

Very cool.

 

I was looking for ghosts in all of those videos

So used to seeing those thermal cameras used on ghost hunting shows. Yes, i watch them.

More seriously: Very cool idea.

 

That is very cool to see that during the pull, thanks for "borrowing" the camera from work.

 

very cool scientific test, but this should be expected when running on a dyno, not moving enough air like when you are tunning on the road.

 

Cool info !!!!!!!
