Group Buy: DSE-VP-HS-001 – Gen IV and V Airbox Intake Heat Shield

[Simms]

When you look up the P/N online it only goes to 2013... Wondering if they decided to not put them on after that for whatever reason.

I never really drive in the rain. Can't I just plug it up? Wouldn't that be best to keep the heat out?

Sure, that would work for temp. I woild be somewhat nervous and would want it to be removable. Washing could get some water in there too. Or a sudden pop-up storm.

I was able to install the 1/8" Dynaliner yesterday. Although there are many adhesive back insulation products out there I chose Dynaliner for a few reasons:

- closed cell (no water absorption)
- designed for automotive environment (resists oil, chemicals, durable)
- 1/8" thickness (allows installation on most surfaces of the shield without interfering with fit)
- dark gray color (blends in nicely with the shield color)
- claims to have the highest heat blocking properties of any single layer synthetic foam

Installation was simple, and all in it took about an hour to cut everything out, test fit, adhere, and install on the car. I simply laid the shield over the foam and did some tracing to get a rough shape, and refined the shape before adhering.

I ended up doing the entire inside of the main shield, entire bottom of the main shield and bottom of the tube shield. I wanted to keep the black appearance on the most visible surfaces. In hind sight I should have installed the foam on the inside of the tube shield but did not do so at the time. I used almost the entire 32" x 54" sheet (purchased on eBay for $43).

The test results were encouraging, however, I didn't have time do remove the shield and do a back-to-back:

Ambient Temp: 81 degrees F
DSE Heat Shield with Dynaliner foam installed
3k RPM constant runs: IAT = ~91 degrees F or 10 degrees over ambient
3 minute heat soak: IAT = ~107F or 26 degrees over ambient


Compared to my previous run (66 ambient) this improved the delta running IAT by 4 degrees and soak IAT by 17 degrees

Not bad for $43 and an hour of time. The results could possibly be improved by adding a second layer along the outside bottom of the shield, along the outside of the sides, and along the inside of the tube shield. Note, the first run was even better (6 and 23 degrees over ambient) but I think things got thoroughly heat soaked after the first cycle of running / soaking. Also, the fans were definitely on when idling but the temps weren't climbing at a rate previously seen.

This also has the added bonus of cushioning the contact points between the shield and the car.

I wanted to tabulate the readings I've been able to take so far. All of these attempt to be as scientific as possible, even down to the same stretch of road for running and same parking spot / direction for idling. There are a lot of moving targets when measuring IAT!

I'm just about done with the install of the heat shield which really is a quality piece. The only area I ran into fitment issue was the passenger side mounting hole on top of the radiator needed to be lengthen a little. One minute w/ a round file did the trick. However with the supplied thumb screws, I am not able to tighten them as much as I'd want and the front of the air box is not being held down 100% as a result. I tried using pliers to turn the thumb screws but my pliers are either too large to fit in there or too small to grab the thumb screws. Does anyone have issue tightening the thumb screws?

Bruce,

Yes I can send new thumb screws. I found some of them for the Gen V had been machined out of tolerance. Unfortunately I only found this out a few days ago after I shipped all of them out.

Thanks
Doug

Yes Doug please send new screws to the 91748 address. Thanks.

Did mine with 1/4" Dynaline on the inside of the airbox and the outside of the tubes, worked fine.

This is right amount on the money with what I've been seeing between 6 and 10 degrees over ambient while moving down the road. Using shield, dynaliner and provided drainplug with tip cut for draining. I do drive in the rain some of the time, well more slide above the above the rain with teh wide corsas on it.

This is also with full ARH headers, cat deleted, Corsa cat backs, Viper Exchange/Arrow Heads and Cam on the car too, so very impressive heat reduction.

Thanks for the update! It is always good to have more data recorded, especially on a modded car such as yours.
