I got a 87 305 LG4 with lots of mods and i was wondering if I should I rip the insulation off the bottom hood for extra cooling and air flow. If I do will it affect A/C or the paint?

 

The insulation on the inside of your hood does nothing to hamper air flow and the effect on the engine cooling is neglible, all it does is keep the high engine temps from baking the paint on your hood. If it has not already (common) the paint on your hood will certainly fade or even bubble if you do remove the insulation. If you really want more air flow and improved performance by getting cold air, nvest in a cowl induction hood (Harwood).

 

all it does is keep the high engine temps from baking the paint on your hood.


Just remove it. It won't hurt the paint. The paint gets hotter setting in the sun than the engine will get it. I can't think of any problems it will cause. Mine has been gone 9+ years (since I've owned it) and the paint is around 8 years old. No paint fade here. If you want to help airflow, remove the seal on the rear of the hood. A poor-mans cowl induction.

 

i took mine off too. its just for sound dampening...

 

Mine's gone. No problems.

 

my car had been wrecked when i got it and i had to put on new bumper, hood, and fenders. The insulation was hanging and getting on my K&N open element, so i pulled it off. Since im poor i temporarly spray painted (black car, easy to match) the front with $0.98 Wal-mart paint. Its been a year since then and the paint looks just fine. As matter of fact at night or on a rainy day you cant tell the difference. Painting it though this winter.

 

when I got into my car wreck and had to buy a new hood I went ahead and got new insulation as well. For all you guys who dont live in the desert it doesnt matter...but when its july and 118* out...you can cook an egg on the side walk in seconds from the hellish sun beating down. I figured that my engine compartment needs all the help it can get to stay cool. I put the insulation in to keep the hood from being an other source of power robbing heat.

 

mine is gone but i have some other stuff in its place, i'll come back with pics.

 

I took the weather striping out too. not sure what good it really does.

 

Removed Weather Stripping= Poor Mans Cowl Hood

 

That stuff is a sound deadning dust collector that will reduce the folical count on the top of your head everytime you work under the hood! Besides, the paint under there looks cool every time you raise the hood! Have you ever seen a show car, race car, or anything modified with it on there? NO

 

I just took mine off this weekend when my rad. hose spung a leak and ripped it with the high presure water, It looks much better now.

 

Anyone have a pic of thier "new" hood without the junk.

 

i removed mine and the weather stripping becausue i have a kn xtreme lid and the insulation was sucking to the top filter!!!! but now i have the ss hood so no problemos.
removing the weather strip alows for the hot air to escape quicker!
