Default No Hood Liner???

Does anyone run a stock hood w/o the hood liner? Is the liner just to reduce noise or does he block engine heat from damaging the hood paint? Here's why...I'm buying the carbon fiber power duct with the c5 logo but don't want the liner to rub off the logo like it did on my Halltech duct. (or do the CF power ducts have a lower profile?). Anyone have the CF power duct that has no problem with the liner rubbing? Thanks.

I think the CF power duct rubs also, at least it looks like mine does...I have wondered about leaving the insulator off also............

People who generally don't end up painting a sweet design or something on it!

or they have to in order to fit a Maggie or Kenne Bell under there!



Example:

I was told the liner was to protect the paint and cut down the noise a little. I don't know if this is true but was also told that in an engine fire the plastic plugs that hold the liner up melt and the liner acts as a blanket to help stop the fire.

a bump for you.

btw, if the fire gets big enough to melt the cover retainers, then I doubt you'll have much to save.

Personally, I have heard two schools of thought on the subject. One was that the hood liner was to reduce heat and keep the hood paint from cracking/peeling. The other was that the liner was just there for sound deadening and that it was safe to run without it. We've all seen cars with exotic paint jobs without it, so it must be OK to not have it.

An alternative to removing it completely would be to remove the small section of liner that comes in contact with the air bridge. Just a thought.

Yep, I believe that the primary purpose of the hoodliner is so that in the event of an engine fire, the plastic plugs melt, the hoodliner drops onto the burning engine, and the fire is SUPPOSED to be smothered - in reality, and speaking from having extinguished numerous car fires (non on Vettes ), I've seen the hooliner drop onto the engine MANY times, but I have NEVER seen it smother the fire - takes some good firefighting foam to get that done
