Ok so in a quest to figure out why my passenger side sprayer nozzel wouldnt work i had to remove the liner from the underside of my hood. (side note if you have a strut tower bar and the NSC engine damper you could possibly pinch the passenger side sprayer tube . . . that only took me a frikin hour to figure out.) So my question. What is the purpose of that liner under the hood ? Is it only sound deadening ? I removed it and cant figure out for the life of me what it was for. My engine is maybe 1 db louder now, no big deal. Anyone have ideas ?

 

Its to keep the hood from getting 1 million degrees. well..... thats a bit over the top but its for temp. I dont have one for my carbon fiber hood and in the winter the snow/ice melts after about 2 mins.

-It may help a tiny bit with noise.

 

yea its for heat, its bad for your paint to not have one

 

I was told it also acts to help put out an engine fire. the clips that hold it up melt and allow it to fall on the fire. not too sure on if it still serves to do that today.

 

I still have my liner and some where the a pin or two fell out. I have been meaning to get a few more from the dealership. I am sure they are pretty cheap.

 

I would put it back on, and just cut out the part that you were having problems with.

 

another thing you can do if you dont have the clips or the mat is apply dynomat to the inside of the hood. A guy in my club with a red rx7 has that done. It looks great and saves his paint as stated.

 

ok lancerman360 wins the "duh" prize for the day. Why the hell didnt i think of that one the stuff is REALLY easy to cut, i can just cut the area out thats in the way. Thanks lancerman360

 

Do I get a prize?

 

yes, ill send ya a cookie >=)

 

i wouldnt use regular dynamat that you buy at best buy or whatever if you went that route, they have stuff made for the inside of your hood that will probabaly sound deaden and heat resist better than the stock crap

 

Whooo Hoooo!

 

well.. If theres something made then that would be better but... he may have some dynamat laying around.... Dont we all?

 

Dynamat actually does make a specific "hoodliner" material that has a metallic film coating on the side that would be toward the engine (to help with heat deflection) and also uses a foam type material (which should deaden sound). Not too horibly expensive, and really easy to install if you take your time.

 

id put it back.
