hows every ones holding up
20k but going to remove soon dont trust it with meth

 

Mine are still perfect, I checked them for the first time back in November when I pulled all my intake and TB apart for cleaning. Almost 60000 km on them, lots of hard driving. Looks like I just did them yesterday.

I used Permatex Cold Weld for mine, and I took a dremel and made a notch grove in the holes before I filled them.

Sorta like this if you can imagine: < > (the blank space in the middle being the hole).

That way if the plugs ever did come loose of the blower, they'd be trapped within the hole at least.



Edit: This is from page four, exactly what I mean, although I only did one rib:

 

Just curious, if the concern is with the epoxy failing over time, why not just use an aluminum plate to cover those holes ? Drill and tap some bolt holes, use Loctite and sleep easy. This is also good if ever you wish to reverse this mod. I'm not sayin', I'm just sayin'.

 

You could, but I wouldn't suggest to the average person to drill/tap it. There's not a lot of material before you are into the rotor area and if you drill through then you are adding more holes where they do not need to be, and running the risk of getting drill/tap shavings in the bearings and other close-tolerance areas.

If you had some plates to give the epoxy something to grab it would be great, or you could have them tack welded in to be permanent but still could be cut off if needed.

 

One thing i still struggle with thinking abuot this project is whether the entire hole must be plugged or if a simple plate welded on the outside would work.

i mean sure the blockoff would be there but now you have 2 pockets where air gets trapped

 

^ I think once there's air pressure in there, the cavities left by the plate won't matter much.

 

Well thats the thing blowers arent supposed to have any pressure inside them.

Another observation i think the rotors passing over the plated airholes might not matter since the airflow would work like a revolving door. But would it still be as effective in making more whine...

 

This mod is stupid and will ruin your blower over time. Heat cycles ftl.

 

I agree.

It is such a silly mod just for sound.

 

Smaller pulley makes plenty of noise. Just GM Stage 2 and the STOCK airbox (not even airbox mod) will make the blower plenty loud.

 

Can always be louder tho. i want mustang whipple loud

I think a 2.7 on an ati with a 3" intake will do it but just to be safe haha

 

Yes sir.

I have my factory AC Delco air filter reinstalled with my modified airbox, and she whines plenty loud.

 

since this old thread was bumped recently, I should probably tell the story. Buddy of mine did this exact mod to his supercharger a couple years back, well i wanna say about october or so of last year we had his blower off the car after running this mod for roughly 3 years, and half of the "quickweld" was missing, engine ate all of it. Motor ran fine, its possible it broke up into small enough pieces to pass right through the motor, but if you willing to risk your motor and your blower for this silly mod just know that it will eventually fail on you.

 

Bam.
