Broke My supercharger??????

[john_V63400]

Well laugh it up guys, my friggin turbine on my inlet side of my SC cracked.
2 of the fins broke off that flywheel looking thing. I think it is my mechanics fault. The 3 inch turbine on the air intake inlet side has some play in it and now it is rubbing against the walls. I think it was installed wrong, thats why it broke after only putting 653 miles on my new engine. What reasons could of this had happened. Does any one know for sure. Oh yeah its a V9 Vortech Centrifical Supercharger with less than 6,000 miles on it on a V6 3400 2001 GA GT

It doesn't sound like the same failure, but...

There are at least 2 other people with the RSM SC kit with broken parts. Unfort for you, I think these guys busted theirs before RSM went under/changed names. So I'm pretty sure they were able to get parts to fix it. Read the threads for complete info. Not sure if it would be possible to do the same thing now that RSM is under a different name...

How would your mechanic screw up the end play? Wouldn't that be the manufacturer? Unless you have to take something off to set it up but that makes no sense to me.

Sorry to hear that...I just got mine back from RSM.....bearring destroyd the drive shaft and the sent it back completely rebuilt....new shaft yoke and pully with new bearring........but........COD $110.00 for shipping !!!!!. It cost $48.00 to send it.......but....I got it back....thats the main thing......now I dont know if or when I am going to put it back in......I think what REALLY happend is the connecting pin that connects the shaft came out( see Bens ClubGP links above) and thats what took everything else with it. I think what I am going to do is take the newly repaired shaft to a fabricator and see if a shaft can be produced that can be more reliable before I risk this happening again !!.

I think thats what happened to you too..........the shaft connection came loose and the pin or whatever part of a part broke something else.

I had less than 12K on this RSM setup and it came apart....I guess I was lucky that they actually fixed it....took 3 months....but I got it back.!!

Now the question is.......how do I make their design better and share it with others that have thousands of dollars invested that have a ticking bomb....ready to blow at any time.

I know TE Johnson will say...."TURBO" but we have way too much invested at this time to convert now....and if we do.....who is gonna buy the RSM settups that we already have????

that's really F'd up!

By the way a few words for all the people with RSM stuff.

I was told by Zsolt, one of the owners, that a company called Z-Spec had purchased the rights to the RSM catalog.

I emailed Z-Spec for some info and the returned email with the info was........drum-roll...........Zsolt.....from RSM

Seems they have changed the name to protect the guilty....so if you have issues with RSM........contact Z-Spec and you will be communicating with either Nelson, Zsolt, or Frank.....same people.....same runaround, same short ambiguouse answers to specific issues....SAME, SAME, SAME

You know, if somehow it could be setup with a pulley and belt on the other end of the shaft to turn the S/C that would probably get rid of any inbalances and dampen the vibrations going into the SC. It would probably last longer.. The vortechs are made to have a pulley right on the S/C anyways.

Heck if you could make a mount to mount it on the other side, perhaps even flipped and move the coolant bottle somehow and directly run it off the drive belt then you'd not have to worry about the shaft at all. Then you could easily route it to a FMIC with the outlet going right up to the TB.

I never liked the shaft driven setup of the RSM. Doesn't it bolt to the heads too causing the whole assembly to get really heated up?

I'd contact Zspec and see what they can do for you. Is it out of warrenty? Or you have no warrenty since you are a 2nd owner???

[zofo61]

I love the idea of a left mount braket and a drive pulley on the pulley side.....no only if a braket can be fabricated for the left....I know we all ,with the RSM kit ,can get the original pulley from Vortech that was designed for the charger in the first place. All we need is someone in the ZZCNC or fabrication industry to fab a braket.........commmon guys ....you know your out there.....chime in and help a brutha............

[IsaacHayes]

Actually looking at your engine bay pics, your coolant bottle isn't in the way, it's your battery. So you could relocate your battery to the trunk, and have a ton of room over there. Not sure if it would work out, but you could take out the battery and hold up the SC in the general area and see if there is room.

Then get some steel and weld up a bracket and find somethign to bolt it to on the motor. That'd be sweet.

[kflo 93 gt]

Isaac, I actually think you're on to something here. Even us Beretta folk could use that set up, we'd just have to go to some W-body front motor mounts, reinforce the rad support a lot to take the torque load, and relocate the coolant overflow jug. It's a decent amount of work, but it seems like a damn good way to fit a supercharger in there correctly.

We need to get brainstorming on this, then have CNCguy rock out a prototype bracket.

[IsaacHayes]

That would bet the proper way to run a vortech. The way they are meant to be run. Only failure would be belts or the vortec wearing out. Not shafts, bearings, etc hammering into the charger. Only tight spot I can see is you'd have to make a 90 degree elbow and run that off to a filter. An L body probably has less space even after the coolant bottle is moved.

[bszopi]

Also have to see if there is a way to swap the rotation of the SC, since if you flip the SC to fit it on that side area, the SC would then be spinning the opposite direction it was originally.

[IsaacHayes]

Easy, just put the cone filter on the output side.. lol j/k. Maybe Vortec makes different rotational models?

Only other idea is to put it in place of the A/C compressor if there is enough room. Or put it where the Alternator was, and move the alt to where the a/c was.

[john_V63400]

I took my supercharger apart and the bearings are broken, Could that be from not alinging the drive shaft or over tightning the bolts.

[SappySE107]

I would say that is a possible cause for broken bearings.
