I don't care what ZZP says about porting the silencers, Eaton says no. I think you may be confusing the silencers with the outlet in that case, porting of the outlet will lower IAT.

An Eaton rep has also said plugging is fine, they're only there so the blower could meet noise standards.

 

zzp tested things and knows what they're doing, yes. but eaton designed the damn thing, so i'd listen to them over anyone. if they tell you how to mod the thing, then they say 'don't use jbw on the silencer holes' ... i wouldn't use jbw on the silencer holes, nor quicksteal! and it's not the whole glob coming off going through the manifold, it's tiny pieces that are big enough to get through everything and possibly cause a problem i think he's worried about, cause that's what i'd be thinking about. small enough to fit through the cracks, but big enough to cause a problem internally.

i think a plate of some sort could be a good option, could be fabricated at a machine shop i'd assume. maybe even the place you're dropping the supercharger off at. that's the route i'd go. if you end up not liking it, you have an easy fix for it!

 

I've been running for over 35000km with Permatex Cold Weld on my silencer ports, I just had my supercharger off two weeks ago and they're in there snug and tight as ever.

I dremeled a slight v into the edges of the ports and made sure the cold weld went right in there. If for some small chance it did come loose, it wouldnt be able to come out of the port due to the shape of it.

 

There was a guy on here selling little plugs that were CND'd aluminum and filled the holes. I think if you were to use those, then Quik Steel, you'd be golden.

 

Quit being a girl and just use quiksteel....

 

this guy is smart right here

 

Post a picture? You've got me confused.

 

this is the worst idea ever...

 

Yeah i know i mean that if it having the holes came down to a performance thing you think a TVS would run them

 

I could be wrong, I am nothing close to being engineering minded, but it seems to me that port holes to lessen noise would make a SC less efficient. So I am not sure why they shouldn't be plugged if they are ONLY used for noise purposes.

 

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.

 

Ok gotcha. I just bought a TVS so it doesnt affect me but I still wanted to know. Thx

 

Ya know what, thats a good idea! Maybe i should just buy a TVS so this doesn't affect me either

 

Funny how all the nay-sayers stopped posting after this.

 

who cares, If you guys wanna ruin your blower go ahead. Apparently 2 different things are being said and claimed to be true. But personally if I can find someone to properly weld the holes and not use quiksteel or jbweld I would try it out for sure.

 

Stay tuned

 

Sub'd

 

lol


100% correct information was posted and you're going with "who cares, If you guys wanna ruin your blower go ahead"

Quiksteel is very permanent, and if properly applied and cured - is NEVER going to come out. It is nothing at all like JB Weld.

I've used this stuff on exhaust components, the heat cycles of the blower aren't going to have much of an effect, and the pressure is not nearly high enough to have a significant effect either..

 

No one was asking whether or not you approve. He was asking for the best way...

For me, i just want the blower to whine louder. Ricer mod? i personally dont give a ****, i just like a loud blower. If it helps efficiency, awesome.

You are risking your motor simply by modding your car...so why mod your car?

 

Not sure why I have to keep repeating the info.
If you mess with the blower outlet on this car you're going to lose HP. Deosn't matter what you do really. Plugging the silencer holes? AITs will go up slightly, HP will drop some. Measured on dyno. Copy that, save it, repeat it, post it.

 

How will HP drop? I'm not going to argue with you Zoomer because you have obviously tested it but that makes no sense. As Eaton even says, they are just silencer holes. It's not messing with the outlet at all so i just don't get how it will affect hp?

 

in for that answer as well...

 

Also confused about that. Thought those holes were for silencing purposes only?..

 

and also, if you did a before and after, im sure you did multiple pulls, correct? What were they? Im assuming you did at least 3 runs...

 

IMO there are so many variables, how do they know for sure it was plugging the silencer holes that did it? It's just wierd how Eaton the manufacturer says the complete opposite of ZZP. But if that is the actual case then why not put those holes in a TVS for lower IAT's and more HP? In for actual numbers as well
