Infrared Testing Volume 2 *Featuring Design Engineering Inc. (DEI)*

[HeroCrank]

For this installment of infrared testing, Design Engineering Inc. products is being featured (DEI). The test vehicle will be a stage 2 2011 WRX. There are 3 products that will go through various tests to see how well these products work by themselves, and how well they all work together in the WRX engine bay.





Product #1 is DEI's titanium exhaust wrap, part #010132 2"x35ft roll
also included is stainless locking ties for securing the exhaust wrap
part # 010202 14" locking ties

locking ties features
-can withstand temperatures in excess of 2500 F
- 100 lb tensile strength

Product #2 is DEI's reflect-a-gold foil tape part # 010392 12"x24" sheet
product features
-made of space age polymer
-withstands continuous temperatures of 850 F
-self adhesive
-minimal clearance needed
-ultra light weight

Product #3 is DEI's floor and tunnel shield 2 part # 050501 3.5 sq ft
product features-
-excellent heat and sound barrier
-wind and water will not effect adhesive
-minimum clearance required, only 3/16" thick
-aggressive self adhesive backing holds past 450 F
-easily shape, trim, peel, and stick. sticks to fiberglass
-constructed from 10 mil aluminum bonded to a finely woven layer of high temperature resistant glass fiber

stay tuned for the results of this infrared study. these are very common products used on our cars and we will finally know how well these all work.

Did DEI hook you up?

curious as to where you plan to put this

Probably on the end tanks of the intercooler and y pipe underneath that is attached to the ic. I also did my Cobb SF cai box so no radiant heat can get through and some have done the underside of an aftermarket turbo heat sheild.

he has a wrx and it has plastic endtanks thats why i was curious

i dont know, thats why i sub'd to this thread

[gtasti]

I'd love to get some of that gold stuff
Looking forward to the update

[cheizy]

How's it coming along?? I just wrapped my tmic with that gold dei stuff

its going great, infrared testing is almost complete. be looking for this weekend hopefully!

I will ban you unless we get a picture of you or someone farting on that camera.

i was thinking of that, ill make a special thread just for that one!

I used the titanium heat wrap on my COBB catted downpipe. Installation is straight forward and the process of removing the downpipe takes me about an hour each time. I would say the whole thing should take someone around 3 to 3.5 hours from start to finish.

these first infrared shots are the before heat wrap. one shot is the engine at idle for 15 min after operating temperature is reached, and one is the componants after driving with a couple of full throttle pulls before opening the hood. these shots will give us our baseline for the duration of the entire study of all three products. keep in mind these shots include the PTP turbo blanket installed.

here are the wrapped shots of the turbo and the downpipe. the turbo and downpipe are the same temperature basically normally. now after the heatwrap the downpipe doesnt produce the same heat as before.
turbo idle

downpipe wrapped at idle

370F-312F= 58F

turbo after driving

downpipe after driving

497F-456F=41F

58F difference at idle
41F difference after driving
thats a pretty decent result just from the heat wrap. from all of my pics of the average difference from the wrap is around 41F-58F of change. now lets take a look at the rest of the changes in the engine bay.

heatshield idle temp before 88F, after 72F
heatshield after driving temp before 91F, after 85F

idle 88F-72F=16F
after driving 91F-85F=6F

total temperature change so far

idle 74F
after driving 47F

TMIC middle temperature after downpipe wrap
at idle

99F-86F=13F
TMIC middle temp after driving

80F-65F=15F

total temp change so far

idle 87F
after driving 62F

(getting previous numbers from the base readings in first post)

I may have missed something (and I've never tried to read one of these cameras before), but I believe what you are showing in your last post is a bit misleading - you've stated that temperatures have been reduced ~40* in some cases. While this is true for some parts of the DP, other areas have gotten significantly hotter. According to your other post, the following is true:

Turbo @ idle w/o wrap: 358*



Turbo @ idle w/ wrap = 370*



downpipe @ idle w/o wrap: 170* (one tiny spot that's ~325* - call it an average of 255*?)



downpipe @ idle w/ wrap: 312* (Whole lot of ~300*)



Turbo after driving w/o wrap: 497*



Turbo after driving w/ wrap: 497* (These look like the same picture, also same timestamp?)



Downpipe after driving w/o wrap: 248* (one tiny spot that's ~500* - call it an average of 375*?)



Downpipe after driving w/ wrap: 456* (whole lot of 456*)



Based on these images, it seems like the small spots of high temps are gone, but there are higher temps overall throughout the pipe. Instead of having a small concentrated area of high heat, you've spread it around and increased the heat in other areas; overall, the rest of the pipe is hotter... This makes sense as the wrap is designed to retain heat.

The heatshield and intercooler do seem to be cooler.

Nice work. Thank you very much for contributing this.

I will continue posting the rest of the DEI products tomorrow. So far we have a great start with the total reduction in underhood temperatures with just one product.

[HeroCrank]

thats not the best baseline image of the bare downpipe, ive got some better ones. some pics are different with the area square and the exact point measurement, so its easy to think its misleading. My numbers are taken from the tests from the same time.I posted turbo and downpipe images from the same moment so the results would be more accurate. You can see the temperature difference between either sides easier.

Here are some foil and shield results

Product #2 is DEI's reflect-a-gold foil tape part # 010392 12"x24" sheet
product features
-made of space age polymer
-withstands continuous temperatures of 850 F
-self adhesive
-minimal clearance needed
-ultra light weight

Product #3 is DEI's floor and tunnel shield 2 part # 050501 3.5 sq ft
product features-
-excellent heat and sound barrier
-wind and water will not effect adhesive
-minimum clearance required, only 3/16" thick
-aggressive self adhesive backing holds past 450 F
-easily shape, trim, peel, and stick. sticks to fiberglass
-constructed from 10 mil aluminum bonded to a finely woven layer of high temperature resistant glass fiber

here is the heatshield underside gold foiled

The TMIC has a combination of the gold foil and the aluminum shield. Only the hot side of the TMIC is gold foiled. The top and bottom of the TMIC got the aluminum shield.

[HeroCrank]

Here are the foiled results

heatshield at idle after downpipe wrap--72F
foiled heatshield at idle after downpipe wrap --74F


heatshield driven after downpipe wrap--85F
foiled heatshield driven after downpipe wrap--72F


im surprised at the idle results but I think that covering up the small vents in the heatshield prevents the heat from moving thus giving us a 2 degree gain. The after driven results are great giving us a great reduction.

previous total temperature change so far
idle--87F
driven--62F

foiled heatshield change idle +2F
foiled heatshield driven change 85F-72F=13F

current totals
idle 85F
driven 75F

[HeroCrank]

TMIC foiled and shielded results

TMIC middle temperature at idle after downpipe wrap--86F
foiled and shielded TMIC middle temperature at idle after downpipe wrap
----------------68F
86F-68F=18F


TMIC middle temperature after driven, after downpipe wrap --65F
foiled and shielded TMIC temperature after driven, after downpipe wrap ----------65F NO CHANGE



previous total temperature change so far
idle--85F
driven--75F

new temperature change
idle-103F
driven75F

[HeroCrank]

Next, I will be using the rest of the gold foil and aluminum shielding to try to reduce the air intake temps. The coolant reservoir right next to the intake along with the 190F coolant lines resting on the intake itself will be the next target. So far at idle we have removed 103F from the engine bay, and we have removed 75F from the engine bay after driving with this thermal package from DEI.

Lots of good info. Thanks for doing this!
