3400 RSM S/C - ALL Threads Combined

[john_V63400]

So I found a major problem on my s/C RSM kit for my 01 GA GT

Everything is still installed, but my impellor on the charger unit does not spin....
All I get is a major grinding, huge vibrating noise. No spinning just a horrid noise.

No spinning means driveshaft not conecting to S/C properly, but how.

maybe something wrong in the reduction gear system inside.
rsm is a centrifugal sc type right ?

Remove from car, Send to me, forget about it...

Well start with the first part of that, and then just take it apart and see whats going on in the gear area... That shaft doesnt go directly to the impellor so that housing right behind the supercharger probably has some issues.

[john_V63400]

OK well iM GOING TO TAKE A LOOK AT THAT, z-sPEC SENT me a message saying I can send it back to them but they want to charge 250 just to look at it.

[3400-95-Modified]

thats bull, didn't you JUST get it back?

Unless you have an oiling issue I don't see why this keeps failing... It is a vortech charger right??? those aren't cheap so its not like its a knock off charger that keeps breaking.

[john_V63400]

yeah vortech....I just got the charger unit back. I had them upgrade the bearings in it since Im using 15 psi of boost.
then I put it on and the same noise, guess its the not the charger unit, or never was. My bet is the housing behind the charger too. Im going to take alook at it and disasemble it right now. I bet I could get someone around Fresno to work on it if it needs new bearings and what not.

[3400-95-Modified]

They sell vortech charger rebuild kits online depending on if its centrifugal or gear reduction.

It appears to be a very simple thing to take apart from the pics I have found, but the fact that they have not seen the major issue when you sent it in makes me wonder how they tested it to be sure what they even did worked...

I wish I had one of these, BUT I would rather take that 4k and spend it on the Camaro I saw on the way to work today... even if it was a 3800 it is still a newer car that I could drive to give my retta a break... and my wallet

I don't remember the details but I remember someone having the same issues, and it turned out to be a small screw or bolt on the shaft that broke. I wish I knew more about it, however it was a long time ago.

[3400-95-Modified]

set screw going from the drive input to the shaft coming from the belt... very good possibility...

I would check that drive setup first, see if turning the pulley will make anything move inside... may be something simple like that.

[john_V63400]

Yeah Im doing it now, let you guys know whats up in like 3 or 4 hours, or even later this evening.

Post Pics......I can help you walk through some of the problems with these kits.

[john_V63400]

Damn, I was at the shop, then I remember dang my camera.
Good news I fixed it. YEAHHHH I DID IT!!!
All 3 set pins shreaded that hold the shaft to the charger unit.
Allignment Key for the shaft input was shread down too
I replaced both the set key and the 3 set pins and reinforced it with 3 more grade 8 allen head bolts.....Since after all theres 6 holes for the driveshaft to input shaft for the charger.
Maybe I never had those allen heads on at all, cause the holes were all ready threaded and all.
Sounds great nice whistle absalutely no grinding.
Just cant get rid of a little belt sqeek while shifting gears.
Awwww I feel so relieved. And it only cost 3 bucks to fix. Oh and I examined my rubber shielded bearing, Well its not rubber. Its da good one, guess the previous owner of the kit replaced it.

Boost vid 12 psi

hey got a rough vid of my car going 60-85
And a clip of the boost
I tuned it down to 11 or 12 psi, it goes higher, but I lowered my RPM's to be safer on the tranny. On track day i will let loose with 15psi.
