I found an article on GMPowertrain.com that describes the LT4 and specifically the Eaton 1.7L supercharger. http://www.gmpowertrain.com/docs/15_...T4_6.2L_SC.doc

Here is an excerpt from that article:
"... The design of the supercharger system incorporates advanced features for noise reduction. The rear cover of the supercharger gear case has changed from an Aluminum casting to a constained-layer damping material designed to absorb radiated noise from the supercharger drive gears. Additionally, the supercharger lid has a constrained-layer damping panel assembled over the discharge port to damp the high frequency content of the air pulsations exiting the supercharger discharge port. This reduces the traditional "whine" noise associated with superchargers and gives a refined yet powerful and pleasing sound to the engine..."

So it appears that in addition to the lid dampening panel, the material construct of the lid itself is also providing some dampening.

Well, I guess that solves that mystery...Also explains why the NX lids are so much louder than stock.

Great job on the research!

As for whomever decided to do both, BOOO!!! We want more whine!!

Sounds like the panel the OP removed will help with making the blower whine louder. Time to remove mine.

Good find! Sound like we guessed right.

Yes, every one of these will be full of oil. This is only showing what has coated and puddled as most is being ingested into the combustion process causing detonation and knock retard short term, and intake valve coking and wear long term. Also the bricks eventually become covered with a varnish as it builds up over time reducing its ability to transfer heat, and eventually restricting the air flow through them.


As for warranty, it is against Federal law for a dealer to void your warranty with one of our systems installed as we do not reduce, eliminate, defeat any functions of the stock PCV system and we retain a closed emissions compliant system (we are NOT CARB cert in CA yet) so if a dealer would be unscrupulous enough to hassle you, got to the FTC site and they have guides and can assist you in filing a complaint.


The only way they can legally void your warranty is if a device or service directly caused the failure in question, which our systems only improve the functions and reduce issues. The issue is most will never dispute a dealer taking advantage of them. We have had only one case of a warranty denied and it turned out to be completely the techs misdiagnosis. Now, can other catchcans void the warranty? Yes, if they in anyway vent, have breathers, reduce or defeat any of the functions of the factory PCV system. And many do just that with how they defeat and vent to the atmosphere allowing excessive wear do to lack of proper evacuation.


And as always, ask us any technical questions and we are more than willing to discuss details on any of this.


Cheers!

No hate to catch can manufactures but buyer beware, our engines cost a ton of money to replace if you have no warranty.

GM will void your warranty!!

Do you work for GM's legal or warranty department? If not please do not post absolutes. I did not read all 47 pages about an LS3 that lost oil pressure, but I do know a catch can cannot cause oil pressure failure. One person's bad run-in with GM's warranty department or bad legal representation does not make an absolute!

•••••••Elite••••,
I understand that when I’m altering any factory application I accept the fact my warranty could be voided. I have yet to install CC on my 6th gen zl1 since it’s not as simple as Ls3 or 5.3 much much more involved than PCV hose removal More needs TO BE MESSED WITH therefore much easier for manufacturer to have viable rebuttal on warranty denial.

I think y’all (Elite) are giving a false sense of security to those considering installing A CC.
Seriously ***ELITE** saying that the Camaro consumer will be protected from Chevrolet voiding thier warranty is erroneous to be say it nicely. Regardless of what act states OR them filing a complaint.

You and me and plenty others know that very few people have the resources that Chevy has to throw at fighting you on a warranty issue. It’s a very long shot if Chevy wants to void your warranty it’s voided. Take your own example as an example voided even though misdiagnosed.

I understand you want to sell your product but please provide this community one viable case that used this protection after installation of your CC.

Inadittion , specifically one case that Chevy had to unviod the warranty they previously voided on one of the engine application/ not broad spectrum example.

Since this is 6 th gen forum the 4cylinder,6cyliner, lt1 or LT 4.

Now maybe Elite could provide a network of certified installers regionally across the US . Then back up what you sell and say by providing the legal fees and other associate cost of voided warranty after denial of said product on Camaro.

Better than that how about you (Elite) get with Chevrolet and offer this as dealer installed Chevy certified product. That’s my hope .... but let’s keep it real

Until then I think it’s prudent for you ELITE to inform people that the truth is, if you install a CC no matter brand your risking your warranty being voided.

...unless your adding Chevrolet catch can.

Great post. A dose of reality. I just ordered an Elite CC for my ZL1, have had one on my GTO for years. They should not, properly installed, ever cause an issue which would void a warranty. But dealership service departments are operated by people, not robots. Not all are competent, not all have the correct understanding of federal law regarding motor vehicle warranties, not all care. When one of the incompetent or un-informed or deliberately indifferent denies your warranty claim it is not as easy as pushing some magic FTC button to right the wrong, and if your vehicle is in immediate need of serious repair, you may and probably will have to foot the bill yourself and seek reimbursement later. That can be expensive and time consuming. Adding to the uncertainty is dealers who may be sympathetic to warranty claims may nevertheless decline claims from modded cars because GM rarely fully reimburses a dealer for approved warranty work, it is often a monetary loss/ cost of doing business decision by the dealer. FWIW my Dad was a Chevy dealer for 40 years and as an attorney I had significant experience in warranty issues. Bottom line, vehicle owners who are excited about adding mods or improving/personalizing their vehicles can be a bit mislead by assurances that products are warranty friendly or "that there has only ever been one problem" or that you can fix it with an FTC complaint. Not jumping on Elite, I am a repeat customer!!!!!! But as the above poster pointed out, vendor assurances about warranty status needs to be taken at arms length by vehicle owners. It ain't always that simple.

I edited this post from my original response because it was petty and childish, I apologize to those who already read it.

No I am not kidding! I was saying if you do not represent GM then you can not say what they will do 100% and neither can Elite. This thread was about the SC lid. There are plenty of threads on the warranty. I along with others have voided the warranty a long time ago.

So this is great news. If you have a catch can that fabric with be bone dry right? It will remove all that nasty top end oiling?
