Basic Track Data
Here’s some basic track data from this pass weekend. As you will see 30° difference between ambient and IAT. Not sure what’s considered good, decent, and bad. Still researching and new to recording data. This was the hottest part of the weekend at 94° ambient. There were also times this data shows 97° ambient but it never got that hot so not sure if the location of the sensor and long runs play a role in this or not. Even when my ambient temps were 84 in the morning sessions it still would eventually climb to 30° IAT over ambient at the end of 25 minute sessions. Check out the Catalyst temps also. Don’t even ask me about the mass air flow rate. But I’m recording it. Lol.

I'm trying to remember your mod list...
A 30 degree spread isn't all that impressive (not your fault). I like something closer to within 10. I think next time I have my aFe airbox out I'll be lining the exterior with with DEI heat foil due to all the reports of high IATs. I do think the vast majority of heat is coming from the cats being directly underneath (glad I ceramic coated mine).
- Wrapped stock headers?
- Paragon cats?
- Stock intake?

Wrapped stock headers, Paragon cats with a blanket wrap, and attack blue filter only. I’m getting ready to heat wrap the exhaust from the cats on down through the trunk area but not sure that will help with IAT’s. From other forums getting to within 10° on the track is not going to happen but what I’m running seems to close to others. Still researching. But there’s so many different scenarios per car configurations. But I will be working on several more ideas. The airbox is definitely not a good thing, it needs a better location, better heat shielding and there’s no way of going about that quite yet.

So far as the intake I want to have a custom one made. Like the C8R setup. Clean and direct feed from the rear. Just not sure how it will end up with the MAF readings and turbulence if any.
Come to find out I have and had a issue with the 95mm Lingenfilter throttle body. I knew I had a issue before just didn’t know it for sure was the culprit till this weekend and by some crazy coincidence my supplier reached out to me saying Lingenfilter had also had issues on their track cars at certain tracks through particular turns which was also my same issue. So in short without going into a lot of information which it was. For serious track drivers and tracks in generally we were experiencing problems with the throttle body under high load turns which caused a issue with the ESC even if turned completely off and bad turbulence due to the throttle plate and how it was set up. Like I said it’s a lot to it. But it was found that turning the throttle body upside down solved the issue. So that will be the next test.
Ninja edit: They said there was no issue with street driven cars or daily driving which I can contest to this.

Thinking of going to the Halltech system for now in which they also sell a nomex sock that goes over the coupling. I’ll use this system until someone tells me for sure we can develop a good system that should work. It’s all about money in the end. This hobby combined with addiction I tell yea. Pretty much a tossup at this point.

I was actually just looking at a 24x24" sheet of DEI Reflect-A-Gold to wrap my aFe airbox with. I should have just done that to begin with before installing.
I just bought a 36x48" sheet of DEI Reflect-A-Cool (silver) to line the backside of my trunk carpet with.

Halltech sells a 24” sock that fits over the intake tube coming from the air box and will pull all the way up the. couplings and over the throttle body. Just have to put some slits in the fabric to slide the MAF and vacuum line through. I like that so that’s what I got.

I am half tempted to pull my intake manifold back off and line the underside of it with this DEI Reflect-A-Cool (or -Gold) too. I'm using the -Cool on the backside of my trunk carpet, but will likely use the -Gold on the backside of my aFe airbox since it's rated for higher temps.

I just did some quick measuring, and I think a 12x24" sheet will be needed for both the intake manifold and the air box. The air box might actually need something more like a 12x36", but I think I'm going to order a 24x24" and use my leftovers from the trunk project as fill-in.

I just got done with mine. I needed a 12x24 for the back of the intake and had enough to do the bottom of the box. I only did the metal plate on the backside of the Halltech. I also added some heat sleeving to the water lines on the passenger side close to the header. Not too close and there already positioned right at the large intake and fan but hey, why not. Still waiting on the Kevlar sock. Post of shipped same day. They waited two days to get it out. Typically.
Also the Halltech box is 2.5lbs lighter than OEM so happy about that.

I heat wrapped those 3 large hoses on the passenger side too, along with various other lines above the valve covers near the headers (including the fuel line). Glad you got your project done so quickly! Any pictures? Silver or Gold?

30f delta is pretty good.
Your/our exhaust gas temps are routinely in the 1680 to 1790 degrees farenheit range. Ill be interested to see how aftermarket cats hold up in the long term.
We cant even get hjs 200cpsi motorsports cats to hold up very well at that threshold.
The cheaper gesi cats are only rated to 1700f peak.
