sorry if this is the wrong place but did not see any other place for it. And i am talking about an LS1.

Ok i know smooth bellows do not add power and they smooth out the airflow going in? Why would you even spend money on this part? The only thing i heard was it changes the sound. Can someone clarify? Thanks

 

Well the gains will be very very little, it won't change any sound Most people just end up with a cracked lid because of lack of flex when the motor moves....just my .02 cents

 

Ya i heard about the flex. i dont think im gonna do it when i get my Z. Some idiot friend said something about sound. i dont even remember what exactly he said. just thought id check since he has a 00 trans am. some of the things he says...

 

Could be getting confused with the sound difference between a stock and aftermarket lid. Removing the silencers as they do, will increase the intake sound of the engine under full throttle. Hardly think that a bellow would do that alone. A lid, yeah.

Put your $50 somewhere else.

 

Yup save the money and do some free mods with the time you would spend messing with the belows

 

Whats "Free mods" examples?

 

tb bypass is the only one ive heard thats worth doing. i did it to my V6 and you can really feel the unleashed power. But hey on a v8 it is supposed to be 5 free hp so take what you can get.

 

I did my smooth bellows with a $5 fernco couplet from Home Depot. Didn't take much time and very little money. Check out www.installuniversity.com for the free mods, I won't start the debate again, but I believe in the free ram air mod, and descreening the MAF didn't hurt my car any. The Tb by pass is a good easy one to start.

I have had my bellows on for about a year and didn't get a cracked lid. I would be lying if i told you i saw a performance gain though.

 

I did the Fernco, now I have a hump hose. i did it for looks and the fact I needed a new coupler since I trashed the stock on doing something else. The only real reason I can see doing it is looks. I think it looks cleaner. I didn't feel any gain from it.
