I just dropped off the V with the dealership. They installed the Maggie for me. I dropped it off because this is the second time the serpentine belt has moved. I guess under boost the belt tends to jump off track slightly. Now the issue has become more serious. The belt was tearing on the edge. Pieces of the belt were slapping the other pulleys as it spun. They told me they will cover the belt for me. I was stunned to hear that. The belt comes from Magnacharger.

Now I want to see if any of you know where I can find a company that would sell a pulley I can swap on the tensioner with something that has a higher wall to keep the belt from moving or coming off?

I think Blitzer or someone else on Blitzer's thread about losing boost over 4k rpms because of belt slippage, mentioned the reason why my belt was coming off track. Supposedly, this member had the same issue. He said the hardness of the joint on the belt caused for it to jump off track. After he replaced it, it was fine. I'm going to try that first. If it doesn't help, I'll have to try something else.

What can some of you Maggied owners recommend?

Katech has one...

Thanks Staxxin, however I'm going to call Katech. This disclaimer pertains to me. "*Not recommend for use on supercharged engines."

thats what they say to cover their ass but i have one on my maggie and it kicks ass

I'm running the tensioner that came with the Maggie and haven't had any issues in over 10k miles of running with the Maggie. I think Blitzer and some of the other guys that were having issues had them due to putting smaller pulleys on the blower.

I believe Katech did chime in on a previous post to say the it wasn't just a CYA disclaimer but that they really don't recommend them for supercharged engines.

Your problem sounds more like it could be alignment rather than tension?

When you noticed your belt edge tearing a little had it jumped a groove on the tensioner?Your stock tensioner should be fine with all pullys.Some of these other guys have more mods than you.I went through 2 belts due to hard joints on the belts.If the belt is making the tensioner bounce it's the belt.It will come off at high rpms and has nothing to do with alignment.Been there

I installed the one from Magnason with no problem, but I think Wildwhl had the same problem you described which prompted me to buy another and throw in the spare tire well. However take note, the belt number in the installation book does not match the belt, nor does the belt routing sticker match actual routing so photocopy belt routing out of the install book and leave with spare for that dark rainy night on the side of the road...

That whole manual is a bit goofy.I was told that it was actually a GTO manual that was cobbled for a V. If you look at the views for the fuel inlet youll see they all face/connect backward. I sent them a long list of corrections. No reply.

ok forget the advice. leave the one you have on. i hope it jumps right off the pulley

???:hmm:
Katech may have a good tensioner but "*Not recommend for use on supercharged engines." worked on me and caused me not to buy it.

sounds like alignment, wrong belt, original tensioner, or bent/out of round crank pulley. search similar post by wildwhl.

no problem with mine, out of box and plenty of WFO time.

 

[wildwhl]

Since replacing my belt with a "cogged style" and softer belt (no hard joint) I've had zero issues with the tensioner supplied by Magnuson. Also, the seemingly out of round crank pulley/balancer was an optical-dilusion (brought on by one too many dark beers?).

The same belt has lasted me about 5,000 heavy boost miles, with 3.0, then 2.8, and now a 2.6 pulley :thumbsup:

Once a belt has been nicked, or ever so slightly damaged, it is doomed. Try a new belt and see what happens.

Denniscars is correct - the part number and diagram are incorrect in the instruction manual.

Hey, threadjack on, but did I tell you guys about the M5 I rode in and drove while in Germany

 

[DILLIGAF]

No,but welcome back

 

[wildwhl]

Threadjack continued.
We were in Rudesheim(sp?) and walking through one of the narrow streets I spotted a black M5. I of course had to take pictures. While there, out steps the owner from a pub. We start talking - me of course about my supercharged V, beer, and food and he offers a quick spin.
The part of the country we were in there really weren't many roads (or at least to my knowledge) to open her up. He demonstrated the SMG and launch mode quite well. Don't be fooled - the car hauls ass. I drove it quite tamely back until the streets were too narrow for me again (about 10 KM). Really a nice car.
Now, is it TWICED AS NICE as a V? Nope. I'll keep mine. Seriously cool. Really sweet. And for the $100K+ that it will end up costing in the U.S. for the first few years - it had better be.
Chance of a lifetime and another confirmation that everybody we met while in Germany was courteous, generous, and liked BEER!
Threadjack off and I'll say no more. Glad to be back on American soil. Now if the dealer could quit F'in up my V and get it back to me (another thread, another time - but they somehow broke the mallet shifter in half).

Photo attached of course doesn't show anything other than I saw one - but those that know me know no b.s. when it comes to cars. Was the wife impressed that we had to talk cars on our trip :nono:
WW out

 

[Dennisscars]

Nothing like going fast with a stranger in a strange land who just came out of a pub...

We GOTTA get some of them rotors!

Welcome back.

 

[wildwhl]

Whatever happened to the drilled rotor group buy?

 

[VELOSE]

rp64ctsv, yes, it jumped a little and while I let it stay there rubbing against the edge of the tensioner pulley, it ripped a small piece along the edge of the belt.
1MEANV, you are Minnie.
wildwhl, welcome back. Thread jack was fine because your story sounds like something that is definitely out of the ordinary to do while on a normal persons vacation. On a wildwhl vacation, that might be ordinary. :alchi:
Dennisscars, I'll go ahead and have a belt as a spare just in case. Also, you might be right. I got a call from the dealer. They said that the pulley needed alignment. The new belt has been installed as well. I'll go ahead and bring it to the technicians attention to see if he remembers installing the magnusson provided tensioner. If the stock one is still on, I'm going to kick ass and take names later.:banghead:
Thanks for all your help guys.

 

[Katech]

We really do not recommend using our tensioner on supercharged engines. The instantaneous loads placed on the belt really require a dynamic (spring loaded) tensioner. I have heard of people using our tensioner with a supercharger without a problem, but I do not know their specific circumstances. If you're still not convinced, watch this video and keep a close eye on the springloaded tensioner.

enjoy

Katech, Thanks for weighing in. :highfive:

Velose, here's the gates belt that I'm running. K061037

 

[VELOSE]

:yeah: Thanks Katech.

Since the dealership already installed a belt, I'll give that one a try for a little bit. Meanwhile, I'll get one with your part number as a spare. Thank you.
