Thread: Rebuilding a supercharger

I plan to rebuild my supercharger soon, it was making a grinding noise. I've seen different kits, ranging from $65 snout rebuild kits and up to $500 for a whole supercharger rebuild kits, I also read that its usually the coupler that makes the grinding noise. I also saw a couple places where people just rebuild the snout and replace the coupler... so my question is, is all I have to do is replace the coupler? Or should I rebuild the snout as well? And should I rebuild the whole supercharger? I'd rather not spend 500 on rebuilding the whole supercharger... And if anyone know's of any good how to instructions(preferably from experience) that would be awesome to know

I don't want to buy a new one cause that's no fun.
And for billboost, any idea on how to find exactly whats wrong with it? haha

Hippo. Sometimes its not that simple. In my area a new supercharge is about 1900$ the rebuild kit is about 600. So just buying a new one isn't always a financial option. And from what I have heard, the rebuild on one is actually relatively quite easy.

I took my car to Aamco to have them rebuild the supercharger because of a whizzing noise that came from the supercharger (what they told me). I bought a rebuild kit online that replaced the snout, bearings and coupler and my car is still whizzing. They're trying to figure out why its still making that noise and how to stop it, does anyone have any idea as to what the whizzing might be and how to stop it?

Is there any place that sells the rotor pack?

zzp sells rotor packs...

It was a whizzing....Aamco claims to know what they think the noise is. Will provide more details later, but sounds like it wasnt exactly the supercharger.

if you have coupler play (pulley will move before engaging rotors/box of rocks sound) replace coupler. if you have score marks on the inside back of the case the rotor pack needs attention. marks on the edges of the rotors or rotor bores scored the needle bearings need done. snout bearings rarely go bad but they're cheap and easy with a press.

rebuilding a blower (minus the rotor pack) is simple. it should not cost you that much to do it yourself if you follow an appropriate walkthrough.
