Doug Shelby heat shiled

[blingnoring]

I got around to installing the Doug Shelby heat shield Monday, install was pretty straight forward, great directions and pics but after i finished sticking the dynaliner to it, i noticed it looked a little thick, so i checked the box and they sent me the 1/4 inch instead of the 1/8 inch. so i went ahead and installed it on the car anyway and it fit. the shield cleared everything so i let it sit in there for about an hour to see what it would do if anything to the dynaliner.

when i took it out there was only a small part pushed in from the clamp of the tube. now these are Doug's tubes with his clamps, but i'm sure the stock ones would leave the same mark. so in my experience, you can get away with using the thicker 1/4 inch dynaliner on a Gen V.

just to clarify, i did the whole inside and top and bottom only of outside of the heat shield part, not the outer sides of it and i did top and bottom of the tube portion of the shield. it came with Loctite to screw the two shields together so i waited about 6 hours to take it for a ride.

Also, my car did not come with a rubber nipple on the drain hole for the air box so i used the one that Doug supplied. you are supposed to cut the bottom of the nipple to allow water to drain out of the air box. the larger the cut, the better drainage but the more heat enters the box. the smaller the cut, the less heat gets to the air box but the less water is allowed to escape. So since i don't drive my car in the rain and cover that area when i wash it, i just didn't cut the nipple at all.

so keep in mind, in my comparison with stock, take into account the thicker dynaliner, Doug's smooth tubes and the nipple not getting cut. Also, this is not the same day comparison but both days were partly cloudy and guessing similar humidity.

couple weeks ago i took a 9 mile ride to an auto parts store it was 62 degrees outside and my IAT's fluctuated mainly around 84 to 88. after parking the car for about 7 to 10 minutes, started the car and the IAT was at 102. as the car was moving it came down to the mid 90's and ended up at 90 when i got home.

With Doug's heat shield and tubes, that same trip, it was 46 degrees out yesterday and i let the car warm up with oil temp getting to 140 (as i always do) before i take off. the IAT was 53 when i started the car and stayed at 53 while the car warmed up. as i drove out of the neighborhood and got on the main road i got a flicker down to 51 then back to 53. there it stayed until i hit a few traffic lights where it climbed to 58. after sitting at the parts store for 10 minutes, i started the car and my IAT was at 68. as i drove it climbed down slowly and when got home it made it down to 58.

what impressed me the most was not only how much lower the IAT was, but how much slower it would take to inch upward. i am very happy with the results and can't wait to install the crank pulley which i also got from Doug. very good quality on both products. thanks Doug

Ditto. Blingnoring, Sorry but I honestly cannot read posts that don't use paragraphs. Too hard on my old eyes. I skipped your post for this reason. Maybe you can go back in and edit to add paragraph breaks. Thanks,

yeah it was a long day at work sorry about that guys

TLDR DSE IAT heat shield is quality and works great.

I assume that's the gist of the post lol

To add some additional test data to this post, a couple years back a friend and I were waiting in a long line to get into large annual DuPont C&C at a local airport. Stuck in stop and go traffic for 30 minutes and the ambient temperature was around 80:

• My IAT was 100 with the DSE heatshield and dynaliner
• His IAT was 130 with no heat shield

here is the simplified version, tests were done on different partly cloudy days.



stock outside temp 62 IAT: 84 to 88

DSE shield outside temp 46 IAT: 53 to 58

to me this was a big enough difference where I believe it is definitely worth having the DSE shield and tubes. if i'm not mistaken, Gen V's start to pull timing at 77degrees so keeping IAT's down as best you can, especially in hot summer days, makes a big difference in power.

98 Intrigue, wow that's a big difference
