jb weld chime in

[Tatom Mack]

any of you guys put this inside the super charger?

[PoorSvtman]

if your talking about jb welding the silencer holes, i did this a few weekends ago. While i was cleaning my intercooler my friend preped and jbwelded mine up. So far so good. Blacksunshine was over during the prepping stages.

If you want to hear it let me know. BcLightning was with me for the first test drive.

when he tapped the Throttle Body the blower sounded like it was at wot on a dyno, any it was probably only at 1500 rpm, lets just say it freakin loud

if your talking about jb welding the silencer holes
WHAT THE FSCK are you talking about??? :eek2:

[Beaudee]

Pics!! :eek2:That stuff usually comes loose, wont get sucked in will it?Recommend drill and tap, pipe plug or set screw, loctite if in dang. area!Sounds interesting!!Reason??? Sound??

[PoorSvtman]

It wont come loose.... Tons of people have done it on nloc and no problem. Its been about 3 weeks and i havent had a problem. IF it dose come loose it wil just sit on top of the intercooler. IF you use the jbweld right it wont ever come off.

When you plug the 4 silencer ports the supercharger gets louder.

Hmmmmmm, ok, where are the silencer holes?

[PoorSvtman]

take blower off, look on bottom there will be 2 silencer holes on each side of the main hole....

[dboat]

Ok,
I am at a loss here. I dont remember anyone posting before about silencer holes and filling them up with JB Weld or bolts or anything else. Will someone give the whole story about these holes and what they do and why you would want to fill them up?
Thanks
Dana

First if you do a search on NLOC you will find posts about others doing this..

The best way that I have found through my searches is the jbweld. It can withstand the heat and well its jbweld and it works. Others have used epoxy or have had them atcualy welded up.

When you plug the holes the blower basicly just gets louder, the whine itself is louder. For example, the first time you put on the open air filter and the blower whine is nice and loud and so sweet sounding. Well Its like that bout probly 80% louder. Before i couldnt hear the whine over my loud arse exhaust but now i can.

The reason I did it was-
1. I had my blower off to clean the intercooler for a second time, change the fluid and to take a peek at the inside of the blower case. I was curious what it looked liked with 103K miles.
2. Nobody else has done it localy, so i figured id be a the test mule....

So far its doing fine. Ill probly pull it in a few weekends to see how its realy doing...

If anyone wants to do this and wants some help let me know.

scroll down almost all the way and you will see pics of the process...

Does this gain any more boost?If it is winning louder, it must be working harder?

[PoorSvtman]

I wouldnt think just by closing 4 little oval holes it would make it work harder...

Its kind of like a flute or something... when you cover the holes up on it changes the sound but you dont work harder.

I cant say that i gained any boost, but it dose seem to boost up a tad quicker, that could also be do to me cleaning the intercooler as well.

[Tex Arcana]

I dunno.. seems silly to me to reduce the efficiency (what it is, anyway), and make it even noisier.

[PoorSvtman]

your not reducing the efficiency. It actualy probly makes for a cleaner air path... Look at other blowers they dont have silencer holes... If you can prove to me that blocking these holes hurts it please prove me wrong. Seeing as some on nloc have seen a lb or two of boost increase. If this is true or not who knows. Also apten will weld these shut for you. I think that since they have done research on the port jobs they do and if they felt that closing these would hurt performance they wouldnt be doing it.

I didnt feel or see anyloss of boost, it actualy seems to boost faster than i did.

[PoorSvtman]

Also do a search on nloc or f150online... Im not the first or even close to the first person to do this.

[Tex Arcana]

I know, I read your link; but it flies in the face of the whole porting objective in the first place. I would think that, in order to improve airflow and reduce internal heating, opening up the exit port is crucial for better efficiency.

[PoorSvtman]

The silencer holes are on the side of the main hole....... The eaton is going to spin hot no matter what, thats a give. But I see no way that blocking the silencer ports on the side can hurt performance....

I think it would actualy give a better air charge.... I can see how some could see a increase in boost. If you think about it, the air cant leak out of the little holes, with that happening the air pressure coming out of the main large hole is greater and more effective... Boost is baisly air being shoved into your motor...so with more air being compressed and shoved into the intake/cylinders its probly better for performance....

I believe eatons are the only ones with silencer ports, so it must not hurt performance any......

[BLACKSUNSHINE]

Yeah I meant to ask how much louder that made your blower. Also I you want to get together this weekend and do mine im in, Im sure it needs a good cleaning too.

okay.. thinking this thru.. the vanes compress down the middle, and can move the air from rear to front because they have that slight twist in them, so air comes in from the back, gets compressed as it moves forward, and dumped out the lower port. IIRC, porting opens up that lower port, and adds a couple more along the intersection axis of the vanes, meaning those silencer ports get removed.... I think...

Anyway... hell, I'm still not sure how the silencer ports work... so I'll shut up and think a bit more now. However, despite the blower whine being a nice sound, I don't like it drowning out the exhaust sound, or simple conversation. :tongue:
