well as i promised here it is after 5k .............................


right were i left em...









heres the reasons i took it off


































please feel free to comment....


that paint in the background is NOT what i used ... i used VHT high temp flat black,


yes i know theres a run on the snout

 

Very nice sir!!!! So how much louder was the whine with it plugged? and also how much louder is it now with the 3.5 inch tb? thanks!

 

i ported and polished my orig TB its the same size as the spacer and inlet of S/C... not much much louder but it is heard under low boost now, dont get me wrong though its louder especially with that pulley whew

 

Plugged silencer holes FTMFW!

 

What does pluging the SC holes do?

 

does that paint make the s/c get hotter? cuz that looks nice.

 

Makes the whine much louder.

 

The two oval slots on the output plate are air leakage ports. Their only purpose is to decrease operational noise from the blower. Arnie, from Eaton Corp., explains their function like this, "When you stomp on the gas, the boost shoots up and the air flow goes supersonic. The air then slams back into the output plate and through the leakage slots, which reduces the hammering of the air into the housing causing less noise. The OEM can not have such loud NVH, that’s why we put them in the housing. The 2 small ports are not there to feed air, only to reduce noise." Basically, for the best flow and most efficiency, these ports can be blocked off, making the outlet port (triangle slot) the only port on the outlet plate of the housing. Closing these ports will not increase IAT's; however, it will make the supercharger much louder when in boost. As an example, aftermarket supercharger companies, such as Harrop, Roush and Magnuson do not use these slots in their blowers.

 

Can you please tell me where you got that adapter plate?

 

Why the hell is you S/C outlet Brown? That **** is Nasty!!!

I've got 55k miles on mine... and it doesn't look that damn bad.

Oh... and I checked my Plugs too a while back.

They are there... right where I left them.

 

i was wonderin the same thing ... i hope thats not oil from blow by.

 

It would probably be from that vent tube that connects from the Valve Cover to the Intake... but I doubt it. My throttle body was nasty as hell at 50k... the outlet of my S/C wasn't really phased... maybe a little bit of discoloration... but nothing THAT extreme.

 

what did you use to plug up the holes...JBWELD??? and weren't you afraid of the weld chipping off and falling into the manifold..i used jb weld on my exhaust one time...i know the blower dose't get that hot..but still when i did that is just started to chip away after like a week...

what did arnie say to use to plug them up

 

OH god no DO NOT USE JB WELD. QUIK STEEL is what everyone is using

 

JB Weld = ****

Quicksteel = Awesome

I've said it a million times and don't feel like saying it again. Just trust that Quicksteel is awesome. I've seen someone plug a hole in their block with Quicksteel... successfully (it almost lasted 10,000 miles... until the rod put a larger hole in the block ).

 

... if quicksteel is so awsome he should have been able to get more and plug the hole again and keep going

 

Doing All This This Weekend, Paint Blower Port/polish To Match My Ls4, New Coupler, New Oil, Grease Bearings, Fill Silencer Holes

 

Nice,

I plugged my silencers holes and started a new thread about it on RLFs and most of the tupperware owners freaked! Most of them don't understand that there are other forums with intelligent members working on the LSJ.

Noone had heard of doing this because they never do any research and are content to discuss GM Stage 2 prices and fuel economy all day long.

Out of the 25+ people I have found who have done this only 1 of them had problems and it was because they used JB Weld. I have not found one person who used Quick Steel and ran into problems...

Thanks for the update.

 

what procedure did you use to prep the holes

 

You should polish the tops of the fins on the s/c.
And like above me, why the hell is it bronze colored?

 

Keep taking smack slowbalt owner. I have met a lot of cobalt owners who are cool. Your the first I have seen and read to go cry to another forum becasue they didn't agree with you.

 

i wanna paint my sc black so bad

 

Mine has been plugged for about 5-6k, everything seems to be good so far!

 

i have a awesome digital camera, trust me it dosent look that bad to the naked eye...

i noticed it mostly after i started spraying meth with orange food coloring in the mix to match my car... its more orange than brown, but it does have a oily feel to it? deff not from the valve cover breather cuz then it would be in the intake which it is not, and i cant see it being blowby cause i have 14xxx mi on my car and i never ever burn or lose oil, i do routine compression, and leak bown tests (the mechanic in me makes me do it all the time, every oil change which is every 2000 mi)


but yeah if any one has any other suggestion of what or how or why it would be there id love to hear...

 

Still ebristol you have to admit it's kind of a big risk to take for a sound modification (ie scare the hell out of pedestrians). But I guess if it stands 5k miles it should be good to go. With a 2.7 that must sound like the world's going to end.

Wait...here's a question...why do people who do port/polish of s/c's tend to increase the silencer holes? (ie stagemeier, others)...if it's only to dampen sound there's no performance reason to increase the size of these holes.

Why do you spray orange meth? What exactly does that do to your exhaust (nothing I'm guessing)
