Are there any drawbacks to this? Does it make interior cabin noise any louder, or noise at idle any louder?


Thanks,

Bill.

 

I just did this last weekend and noticed no sound difference from inside the car (although I haven't yet driven it on the highway). It probably makes the engine a little louder from outside the car. I recommend it.

 

Just curious..


Is this for weight savings ? How much do you actually save ?

 

doesn't that thing also have insulating qualities? or i could be wrong.... jus curious

 

Hood probably gets pretty warm. . .

 

hmmm.... i thought this stuff was to smother a fire... if one happend to occur under the hood?

 

that's what its there for....and for keeping the temperatures down on the hood also

 

yeah i thought it like falls down if there's a fire inside the engine bay, and it smothers the fire.

 

I'm not sure how well it would work to smother a fire in the engine compartment, because air can still get underneath it. But it will keep your paint from blistering if it gets too hot under the hood.
I don't think it's a good idea to remove this strictly to save on weight. Last I heard you have to remove around 180lbs. of weight from the vehicle to gain about a tenth of a second in the 1/4 mile.

 

yes, I think the paint on your hood will show signs of wear faster than other ares of your car if you remove the material

 

I'd probably leave it alone and keep it as is .. who knows, maybe it does have a use for something else other than insulation

 

Mine's been removed for a long time and still no ill effects. Paint isn't burning off or changing color the noise inside is still the same but that's only because this has nothing to do with sound deadening. It weighs 2lbs so removing it for weight reduction purposes is dumb. Lastly, it's 100lbs that takes off around 1/10th of a sec not 180lbs.

 

I wanted to remove it to increase engine noise and more importantly to clean of the look of the engine bay. I plan to put some aftermarket company stickers on the underside of the hood.

One thing I hadn't considered was the additional heat reaching the hood. Rather, I had considered it but I considered it a good thing (why would you want that insulation, like a warm coat, keeping the engine heat in the engine? You want engine heat to dissipate as readily as possible). So the only potential drawback I can see was raised by nostrixoxide---blistering of the paint on the top of the hood. And the only situation where this would be an issue would be after some very spirited driving on a hot day when you come to a stop. The engine's hot, the sun's on it, and there's no wind to cool it off. Also, my car is black....

I guess I'll keep tabs on it now that I've removed the liner. After driving I'm going to check the outside hood temperature to see if it really gets that hot. The hood is such a huge surface that I kind of doubt it will be a real issue....but then blistering paint is the last thing I'd want.
