Did you cut the louvers our in the fender liner behind the oil cooler? The fender liner doesn't flow very well IIRC. There are several louvers that are molded in, but they're not open.
ETS FMIC's work really well. I feel like a 30-40* delta isn't that bad since you're going to get heat soak with just about any intercooler. Your AGP also has a slightly larger surface are (20x13x3.5 AGP vs 20x12x3/3.5/4 ETS) over the ETS.
Awesome to see it finally back on the track.

Before you run into buying a new intercooler, some food for thought- When dyno testing a road course tune, ER will do 5-6 pulls back-to-back on the dyno, with no cooling fans pointed at the intercooler to simulate track condition heat soak. I really don't your IAT-MAT delta is that bad. You have to remember the manifold itself gets hot too, with will raise MAT.

I have to think that frontal airflow at 130mph is a little different than 6 dyno pulls with no fans.
Here is some data, this is after two long straights at WOT with a small break between because of a U-shaped connector where I drop to 50mph for a brief amount of time. First straight I hit 121mph, second main straight I hit 130mph.
First straight MAT goes from 109 to 117F, second straight MAT goes from 111 to 120F. IAT drops from 83 to 77 each straight.

If my car wasn't blowed up, I'd go do some pulls after work to see some comparative data. I have an IAT in the UICP. Seeing temp jump 10* on a straight away doesn't seem right for sure. I though you were seeing it work its way up to 120 over the first lap or two then maintaining that temp.

The AGP intercooler on paper appears to be a solid piece. Could the compressor side of the turbo be pickup up heat during the stress of track heat from the exhaust manifold? I thought you had the hot side shielded or wrapped up pretty well...
#1013
I was super impressed and now I really think it was worth every penny.
There is also a inconel shield between the center cartridge and compressor.

Ok, yep I thought I remembered being jealous of that setup! I am trying to explain why your charge temps would RISE on the straight, and I am not coming up with anything obvious. That intercooler by AGP seems like a good design and construction. I would not go tossing that without some more solid data. You obviously don't have a boost leak that is pushing your turbo out of efficiency... not picking up heat...
Oh wait... Could the inside of the intercooler be oil soaked from that engine oil mess explosion that happened to your car ?!
That would KILL the efficiency...

I would def. go for a a tube and fin IC.. bar and plate stuff is just a large heat sink that is not nedeed on the circle track.

Either way, I figured out if I keep the oil level at the lower hole indictor on the dip stick, it no longer burns oil. It's still 6qts at that level so the motor still has enough oil.

If anybody is interested in seeing a log from an entire session of 7 laps I uploaded it here: https://datazap.me/u/razorlab/thunde...11-17-18-21-22
I had to take out a bunch of the other log items to get the log under the 5mb Datazap limit.

Did some maintenance on the car today to prep it for my next track day on the 28th.
Bled the brakes, changed the oil and I also cut open more of the fender liner on the oil cooler side. It's surprising how little is open from the factory and also surprising how easy it was to cut more holes open with a box cutter.
Hoping this is going to help the cooling...
I had already started cutting some holes before I realized I should take a before/after photo so don't mind the couple added holes in the before photo.

That will help a decent amount I think. I noticed on my car that the left front tire runs 25* hotter than the right front, due to the oil cooler. Which I found Interesting because I didn't notice any difference between grip in the front tires. The NT01's just soak up the heat.
