She's a screamer! Plugged SC Silencer Holes Eaton Supercharger

[GMRedline]

I plugged the silencer holes on my SC today. Call me ricey but I did it mostly for an increase in noise. But it could also improve efficiency a little. Here is a direct quote from Eaton.

Air Leakage Ports:

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. It should be re-stated, that you should consult professionals regarding closing these ports; and do not, for any reason, plug them with JB Weld. Improper closure could eventually lead to pieces coming apart and loose debris destroying the rotors and housing. Opening up these ports will only have a negative effect on efficiency. Do not port them.

I used Magnum Steel which I purchased from Amazon.com.

Here are some pics:







I have not reinstalled the SC on the car yet so I don't know how much louder it is. I will let everyone know how it goes.

For those who fear that they may cause damage to the engine.... You do not know how the IM is designed. There is no way those plugs could ever enter the engine. Number 1, the intake ports are way to small for that plug to fit and Number 2 the Laminova cores are in the way.

I will be removing my SC to install a new IM in a couple of weeks so I can check on the plugs.

Expand on that please. I don't care for this "mod" if you call it that, but there has yet to be any sort of proof that it does anything negative.

Thank god! Alpha does not like it.

I must be doing something right...

EDIT

You know what? F this.

If I wanted to be real ricey I could put stickers on my car like the hunda boys.

Or I could make fake dyno videos of my car putting down 518HP.

Here's some stinkin' LSJ HP Baby!!!

And then if I wanted to really fuck up my engine I would run a 2.7" pulley on 42# injectors...

DIAG: What size pulley when you blew?

Its just a matter of time before an intake valve gets stuck open by a piece of that material a collides with a piston.
