Perhaps mentioning a potential group buy for Swaintech coating might spark the interest of a sponsor? Or have an existing sponsor work with Swain to get their exhaust parts coated prior to selling them?

Dude, you got a twin cat system down to 100 degrees max! What's the secret?

Not sure if you've seen the mod or done it, but there's a few people on iwsti.com that are drilling holes underneath that side vent (2nd pic). Everyone claims they can feel heat escaping there after the mod, but nobody has really done a test to see. Not sure how much you would be able to tell standing still at idle though. Just a thought!

I had some free time today and some extra Lava Wrap from PTP around so I put it to some good use. I wrapped the coolant lines that go to the reservoir.




The lines run around the same temp as the reservoir which at normal operating temperature is around 180F.

These lines run up over the air intake and are attached to it as well. (which is a bad design IMO) One line that goes to the turbo is right next to the TMIC.

You can see how much of a difference in the infrared pics. Both of the temps are in each pic. I didnt poke around any further to see if this impacted any other areas of the engine bay, but every little bit counts.

wouldn't wrapping the coolant lines with heat wrap be a bad idea? you want as much heat as possible to escape the coolant. maybe reflect-a-gold but not the lava wrap. same with the intercooler to throttle body pipe.

Seems like some gold wrap on the inlet would be of some benefit too. Since Its still getting contact from 140* coolant lines... Just a thought.

Exhaust wrap might not be the ideal product for hoses. What about layered products like fire sleeve?

I have not followed all of these threads, so I don't know if this was done yet:
-There is a long-ish tread about the benefits of doing the throttle warmer deletion.
This mod is noe of those "free" mods that people do.
You have two rubber hoses that bypass some coolant through the throttle body, to warm it up at start-up, possibly improving the emissions at start-up, but also possibly increasing the throttle temperature at idle and during hot runs.

The mod is easy: you remove one of the two hoses and you use othe otherone to connect the coolant conduit pick-up to the coolant conduit return, eliminating the throttle body from the coolant system.
This takes 5 minutes, with the TMIC removed first.

What you could test, show and answer the thread is:
-Normal throttle body temperature and post deletion temperature.
-Post deletion temperature after a hot run, is it lower now?

The PS is that you seem to have the plastic intake manifold and I am not sure how the lines are connected with those. I know the old style WRX and the Sti

You are absolutly right. Products from DEI that are made for this application will no doubt be hands down better. This I'd just some extra product that I had on hand.

I wish I had a lot more of that stuff laying around, I still have a small square left over though. Ill see what I can come up with.

Btw, did you get the chance to change out your drivetrain fluids yet? I did mine at 10k and its feeling good in the cold weather.

Not yet, but thanks for reminding me. I kept forgetting to order the t70 bit, and then just totally forgot. Gonna do it right now before I forget again. Maybe some gold wrap too.

The gold foil is better for radiation or convection, it won't be so good for conduction. You'll want an insulator for that.
