Tchuck's Hoodliner Install

Update!!!

Its quieter, from outside. Not silent by any means but I cant hear anything through the hood anymore, even with my ear two inches above. I cant really hear a difference from inside with the windows up, but with windows down the intake seems a little more subdued under load. Could be my imagination... The most noticeable change was in the underground parking garage at my local Safeway. Slightly quieter in every way down there

The hood is also ice cold after driving around for 15 minutes or so (after already being warmed up).

Overall, I don't know that I'd call it a worthwhile mod for the money. In my case, having received it as a gift and loving the modding time, it is a great little upgrade. I might buy one for my other car someday if/when the mod bug bites and I run out of projects. Maybe.
 
Nice review! I love that we are running out of mods and are now just doing things for the pure sport of modding. :good:

This could be a bad thing. Like a thermo bag it keeps the heat in and could heat soak the engine. In the end could be a slower car.

Uhhh, yeaaaaah...not going to vent the hood.

Mini update: No data logging yet but I drove for about 30min straight today, never above 35mph, and the temp gauge is exactly where it used to be (just below 50%).

Looks good, but I was thinking it might keep the inside warmer than normal...may not cause issues, but you'll probably be taking in slightly warmer air. Now that makes me wonder why not wrap intakes in this stuff to keep the warm air from seeping through the plastic or metal? hehe

Someone else mentioned that, and I've been thinking about it a lot lately. In short, I don't agree for two reasons.
First, the oem "heat shield" on the underside of the hood is intended to do the same thing (keep the hood from becoming superheated and quiet transient engine noise), it just doesn't work as well as the Dynamat product in the interest of being cheaper, easier to install, and far more permanent. (The Hoodliner is literally a sticker...)
Second, I don't believe the hood+insulation is intended to aid cooling whatsoever, and in fact having a product in that location with a thinner reflective membrane as opposed to a thick absorptive layer creates an assembly that both reflects MORE and retains LESS heat overall. This in turn actually aids cooling by allowing the heat to remain airborne where it can quickly be expelled out the bottom of the bay, as well as reducing the amount of heat soaked material inside the bay.

In summary, I believe this product to be vastly superior to the oem part in all ways aside from two -Expense, and longevity.

I'm still planning to do some data logging of intake air and coolant temperatures that I will compare to the logs I have from before the install.
