ok don't laugh, my jwt intake heat shield
#21
have you try cutting out a inexpansive sheet metal to that shape, then glue the heat shield fabric on that? Hey, if your set up works then who cares how it looks.
funtionality is beauty in itself.

ok I'm working on a new setup using the original JWT heat shield and I put the intake duct back in place. It's turning out really well. It's much nicer looking and will shield even more heat
#24
you should get a JWT Heatsheild or the injen heatsheild and just coat it with heat resistant material. you could even use the material you used with some strong adhesive. that way it will look much much cleaner and have the same if not better effect

ok here's some new pics. I'm not done. I still plan on filling in that gap to the wheel well to help keep the air from getting mixed up and going down there
I wrapped the living crap out of the intake tube, MAF sensor housing and JWT heat shield. They each have a thick black padding material that just won't let heat thru. Thermotec makes it and sells it in sheets. When I came home once and popped the hood, I took this stuff and held it on the engine and waited and waited to feel the heat - and this is directly touching a hot engine. We're talking like 20-30 sec. It normally takes 4 sec to feel heat thru the normal thermowrap. Nothing. Never felt any heat.
So I have the outside covered with normal reflective thermowrap, then then innerlayer wrapped with this thermo padding. The heat shield has the black padding fastened to it via nylon bolts/nuts/washers since they don't get hot.
I didn't cover the black padding with thermowrap on the JWT heat shield because I figure it'll absorb and radiate heat which isn't what you want I don't think. It'd be smoother though for air flow which might be good though.
Only concern is it is flamable if you try to light it on fire, but normal thermowrap is fire resistent I think. Besides, the strings that tie onto the intake tube are just as flamable and people use those all the time. Anyway, if I ever have any open flames in the engine bay, it won't be because of the padding, it'll be some sort of bigger issue. Besides that, it was ever hot enough to catch on fire, all the plastic pieces and hoses would be melting in the first place
I know in a couple of those pics it looks like there's crap scattered all over the black part, but it's nothing really. The flash just picks up reflective bits if the loose threads/hair from the thermowrap

Hey guys... not sure if you've seen what I've done? I've posted this a few times. Overall cost was about $30 for parts.
Two Rubbermaid clear containers... walmart, target, etc.... $13
One small trash can to make the larger air intake cowl.
Both are Polypropelene, ie plastic
I too was performance oriented over looks, then realized if done right, it doesn't look too bad The first image is my prototype, then I built another one that just looked better. I've had this on since winter and so far so good.

Must make it 2 degrees colder at least.

IMO...
The conical filter has more than twice the surface area as OEM, so a little less resistance when air passes through the actual filter material. What percentage, I'm not sure.
The container seals the intake from engine bay heat. I would say it's 100% efficient.
The opening of the new cowl is about 10% larger than OEM. I basically heat formed and riveted the new cowl to the frame, maximizing the mouth or opening. From that point it only gets larger, sealing itself to the end of the intake container/sheild.
All these little improvements add up to a gain in my book. I can tell you that it revs a hell of a lot faster than when I had the stock box on and that was before any of my other engine mods.
Yea taurran, it burbs when I start the car...

i'm at work so don't have a direct link or anything but I bought it off of summit racing. It's made by thermotec so whoever sells thermotec stuff.
What I bought was actually a "battery wrap" which was something like a 12" by 36" sheet of it. They also sell it in larger sheets. What it includes is the foam/fabric padding then a big adhesive sheet of reflective thermotape. I was pretty impressed by it.
Driving impressions, well even though I wrapped the crap out of everything, I'm not sure I notice a huge difference, but maybe I do. Could be all in my head though. If anything it'll probably help on longer duration hard driving like at the track on a road course.
When I pop the hood after driving and put my hand down by the intake, it's for sure at least 5-10 degrees cooler (maybe more) than on the other side of the heat shield. I can still feel heat radiate off of the body or the frame just above the left front tire area, so I want to cover that up somehow. That foam padding stuff really works though. Heat just doesn't penetrate through it.
I'd like to completely seal off my intake like what Zquicksilver did, but with the JWT intake it's harder because it's quite a bit wider than the K&N filter. I'd for sure put a layer of the foam stuff on it with thermowrap because I think heat still will soak through plastic to some degree
on another note, does anyone know why JWT made that part that connects to the MAF housing aluminum and not plastic? Seems like such a waste in terms of heat and weight. I mean, I've thought about thermo wrapping the back of it somehow, but it seems pointless since the aluminum will just soak up heat anyway from ambient temp

Sentry,
You should be able to use the Rubbermaid bin on the JWT filter. The filter that I currently have is ARS or something?? There’s about 1/2-3/4 inch of clearance around the largest part of the filter. I know for a fact the JWT is not much wider than my filter. I've seen both side by side. It would be easy place the top/lid to the container in between the aluminum piece and the MAF tube after some modifications. I had to build a custom adaptor out of PVC parts to get mine to work, but then again, I can buy any 3" filter and just slide it on. JWT built theirs out of aluminum probably because it's easy to mill/manu., strong, maybe less expensive than plastic for them and it allows them to retain their customers when they need a new filter because of the custom fit.
My other theory... you don't need all that heat shielding if you have mostly plastic parts. Have you ever physically felt the air rushing into the pipe while the car idles? Imagine what that vacuums like when it's at 4k and above. IMO, there is so much cold-dense-fresh air moving thru that plastic pipe that the heat shielding will do little to help. Now if it's all metal, that's another story, but who would do a think like that
