So i'm going to be pulling my supercharger off to machine the snout to fit my 2.6", port the inlet and paint it. I figured would like to plug the port holes while i'm at it. I've researched it and have for a while. All I can find is people using that maximum steel putty stuff which i don't want to do or make a plate to fit in the bottom to cover everything but the outlet which seems like a lot of work. And all the threads i can find are older so just seeing if anyone has done or thought of anything different? I'm assuming tigging it shut would make to much heat and warp it which is why noone has done it. I was thinking of maybe making some plugs out of aluminum to press in and giving them a quick tack so they don't go anywhere. I am fully aware that all it does is make louder whine but i love whine so the louder the better haha. But i'm not going to do it if it's gonna be a pain. Just looking for suggestions/input.

 

In for results.
I have been curious about putting a plate over them and then using the quicksteel or w.e to hold the plate on, so it wont go anywhere.. I also want a louder whine lol.

 

See i'm not keen on the quicksteel at all. I know the chance of anything getting sucked into the motor is small because the cores would probably stop it but i don't want to take that chance haha. Thats why i thought maybe a plug fitted to the holes and a quick couple tig tacks so no real major heat is made to hold them in place would work

 

I've never heard of doing this before but I am assuming you thought of JBW already right?

 

Yeah people of used that too but even Eaton says, if you plug the holes, don't use JB Weld" lol. I would just like to use something more solid and not have keep in the back of my head, " is this stuff gonna fall off?" Haha

 

Please see the sticky on modifiying eaton blowers, and before you port/modify anything make sure to read the link I added recently at the end of the thread. My link includes more detailed info on modifying a positive displacement blower correctly.

 

there is an absolute 0% chance that could happen

you obviously haven't seen this manifold

 

Not only does it whine louder, it increases the efficiency of the blower. Is it a feasible gain vs the negatives? No, but who gives a ****.

If I could find a good way to do mine, I would also.

 

"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."

So find a good way to plug them and you're golden.

/Thread.

 

I've read it several times. I'm just cleaning up the inlet of the supercharger. I'm not touching the outlet.

I have seen the manifold... Several times. But like i siad regardless if it can't fall into my motor, I don't want it sitting in my manifold either. Just brainstorming on a more secure way to plug them thats all

I already knew that haha. / thread? This thead is to think of a good way to plug them. I already know what plugging them does.

 

No, I know, I'm just posting that before someone says that it is bad for the blower.

 

Oh lol. Ya i was waiting for that also haha

 

leave the blower alone. if u dont want the "will it ever fall in" or the "**** did i just suck it down" feeling the best way to do it, is leave the silencer holes alone, and you will never get that feeling. look at the fast cobalts and lsj's in general .. do they have anything plugged? negative. not worth the risk. a 10 dollar tube of quick steel or JBW or whatever else you use could/can cause alot of damage.... worth it?




























































































hell ******* no.

 

Quiksteel held fine for me.

 

not saying it wont hold. but if in the back of your head you are always scared of it coming out, then dont do it. there is always that risk. but there is always a risk when modding your car. personally i would never do it, my intake whines enough for me.

 

Eaton says "please do NOT JB WELD the blower holes", zzp said in an old thread either on here or the redline forums that there is a slight gain in IAT's and no slight difference in power. Don't plug them.

 

this is why I don't like to post here anymore, too much assumption - not enough facts


In order for your engine to consume one of the plugs it would have to get past the laminova cores (I'm not sure on the space between the fins, but I think its about 1/16"-1/32"), through the core supports (I think they're something like 1/4") and through the actual port itself.


There are MANY people here who have used quiksteel, not JB weld, to block of the ports. Mine have been in for over two years.


Also, yes, some of those are "fast" cars.


You have a much greater chance of blowing your engine on a canned tune than you do ingesting a silencer plug, are you going to tell everyone they shouldn't swap pulleys?

 

still, why plug them? for a louder sound?

 

Like I've said b4 this is the first thread I've seen about such a "mod". Does it really do anything besides make the whine louder? And if all it does is make the whine louder, why waste the time, money, and potential risk? Not trying to be an ass, I just want to know the real answer.

 

supposedly it is suppose to make your blower "more efficient" but it's not true, I mean it might a little, but from what I read it doesn't do much of anything besides more noise.

 

Lol i didn't want this to turn into a debate if there are any gains or not. I've already read countless pages on the debate. Higher IAT's is a myth IMO. Or why would a TVS not run the holes? Eaton even said they put the holes there just to make it quieter. In the end, yes the mod is to make the charger louder. Nothing else. Possibly a tiny bit more efficent but i don't really care about that. I was just curious if anyone has done anything other than just plugging the holes with quick steel. Maybe i will have to be the first to try something different. I love supercharger whine what can i say haha.

 

zzp said covering the holes raises IATs a couple degrees, porting the holes lowered IATs a couple degrees. This is fact. You can cover the holes if you like, there is people against it (me) and people for it. Kind of like everything else on css

 

Lol ya you said it. Do you know where i can find the thread where ZZP did this test to make it a fact?

 

agreed, when i had my ss/sc, i loved the whine soooo much, its sucha rare sound you dont come across too often, def turns heads thats for sure, making it louder would be badass, so if you find a way and it works, go with it, ive read quicksteel method and it seems to be pretty efficient, but if you find a better way, then kudos to you my friend

 

The TVS doesnt need silencer holes, because it is a much quieter blower to begin with. It makes less noise (whine) than the M62 due to the extra lobe and twist on each rotor.
