Lightbulb Infrared Testing Volume XX **Open Discussions and Ideas**

I have created this new Infrared thread as a "catch all" discussion place for new ideas, special requests, and healthy, positive, debates. Some of the other threads may drift in different directions because of these discussions, and now we have a place to go to let it all fly.

In a previous Infrared thread I had a request to take some images of the WRX from the outside of the engine bay to see if the vents on the exterior would actually let warm air out at all. Well, here are some images with the hood closed and the WRX with some extended idle times in a cold winter evening. 18F to be exact.

Here are some images of the cat of a COBB downpipe during an extended idle. There was a request to see a cat wrapped with some thermal wrap. Although I didnt go that far, if you referance from Infrared Testing Volume 2, you will find that the thermal exhaust wraps decrease the exterior temperatures by around 50F +/-.

Any chance you could compare how heat is retained in a UEL vs EL header setup?

I don't think that's going to make much of a difference, especially if you compare aftermarket to aftermarket. You really want to retain heat, either keep the stock cast manifold or get it wrapped.

I'd be interested in comparing 3 exact same headers, one naked, one wrapped, and one coated by Swain. You probably won't be able to find that, but it would be pretty cool.

That would be pretty cool, I've got the camera and the time, its just the parts. Finding 3 guys with similar set ups would also be quite the challenge, but hey you never know.

Or if you got an aftermarket header, install it naked, take pics, wrap it, take pics, and then hopefully send it to Swain and take pics. Obviously ambient temp will vary some though.

Difference in el and URL header will only change with different materials/metal wall thicknesses.

Epic indeed. All the more reason to do it. Hell, you could even contact Swain and explain to them what you're doing and the audience that the results would see here and maybe they'll give you some sort of discount. Also may be worth mentioning that they can use images/test results on their website.

Might be interesting to see some data on OEM vs aftermarket radiators, maybe do some tests to see if those aftermarket radiator shrouds actually improve cooling?

My personal observations:

Running a COBB SF intake, ETS TMIC, COBB DP (EWG re-route), Perrin EL, COBB EWG UP, with all pipes wrapped and with a PTP turbo blanket on the Dom1.5xtr running E85 on two different track days (PIR) this fall- after my cool down lap, coming right into the pits and popping the hood I could place my hand anywhere on the TMIC and it was cool to the touch. Maybe it just cooled down after the last lap, but even so to me that means there is considerable air movement and heat guarding, of some sort, going on.

My biggest issue with the heat testing is that the camera is not inside the engine bay, etc., when running at WOT with the air flow that comes with WOT on the road or esp. the track. The testing is just some sense of what takes place.

To me if you are all buttoned up with some combination of heat-beating stuff and you are moving, you are as good to go as these hot-ass cars are going to get. I don't think we can really know what is the "better" way to go unless monitoring of all the variables is considered.

My final thought for those who do any sustained hard driving:

I would love to see Swain's coating put to the IR test as drew was suggesting. I would be interested in the direct comparison of a naked DP, DEI wrapped DP, and Swain coated DP. If I ever go stage 2 I would want to know the best heat prevention.

That would be a great test.

+1, Herocrank do you think we can pull this off? How much luck have you had with vendors donating products for testing?

In Volume 2 testing you can see the comparison of a bare COBB catted dp and the DEI titanium wrapped dp temperatures.

I have been thinking of approaching Swain but I dont have anything to even coat. getting a manufacturer to support, participate, or sponsor a thread/test is sometimes tough. Getting a large number of members interested may be the ticket to getting the ball rolling. Getting my hands on a downpipe is the first step to all of this. Any ideas?

^thanks, so the difference was 95 deg F? That's huge. Wonder if Swaintechs coating can beat that.

any ideas for a downpipe sponsorship? Lets see if we can get a large number of us in support of this with the proper contacts and see what happens. I will do all of the testing and wrench time just need the products.

the results from volume 2 titanium wrap was

at idle--58F difference

driven--41F difference

the 95F was the combined results from the entire engine bay with all of the products from DEI.

I thought you had the cobb catted down pipe? I can lend you a catless invidia for 08+ Sti's and wrx's if it helps. I would like it back afterward though.

I do have the cobb catted dp, but the WRX is my daily driver so I cannot afford downtime or a complete tear down to stock. So to do this i need an extra dp. We can keep yours as an option, ideally would love to spark the interest of a sponsor.

Not that I disagree with the sponsor idea, but if you actually want it to happen it might be better to take what you can get. What does an exhaust manufacturer have to gain from this type of test? Why would they want to sponsor it. DEI is cheap enough that I think we can get a few people to pitch in and cover it. The swaintech is more expensive. That would be the sponsor to worry about in my opinion. However from what I've heard about them they aren't likely to sponsor it. Never know know unless we try though.
