I have seen a lot of people have problems with the smaller supercharger pulley have those litle flat "springs?" break. I thought I got lucky and got one that was good, well, my day finally came, only I don't think others had their engine torn to hell like mine was.

I was driving accelerating and the car lost power, I let off then on the throttle again confused for a second then though maybe my belt broke or fell off. I pull in to the nearest parking lot and start hearing funny noised coming from under the hood.

Park, open the hood and see coolant everywhere. At this point I am confused on what the heck happened and how even if a radiator hose broke how it made me lose a bunch of power instantly. After looking for a few seconds I notice the engine cover sliced up.



Took that off and a rubber hose going to the supercharger had a big gash in it, then noticed down below it my thermostat housing had a big gash through the aluminum too!




At this time I see the pulley had 2 of those flat "springs" broke loose on one end and flapping around and pretty much weed wacked through everything in their path. I looked further and then found it did more damage, below the rubber hose is a metal hose like the one seen to the right of it that is going to the oil filter housing. The lower one had the bolt sheared off that holds the oil hose to the housing.

Another pic of the broken pieces of pulley



So at this point, I need to replace the pulley, get a new thermostat housing, a new oil filter housing, a new vacuum hose and guess I will just leave the engine cover off in the front.

I start to take stuff apart and come to find out I can't get any of it off without taking the damn supercharger off because it is blocking access to a few bolts. Just awesome, so I got to work and now the car is torn apart until I get replacement parts.

Oh man, sorry to hear about that. Being OOC sucks.

Couldn't have come at a worse time either since my CTS-V is in the middle of a built engine install and a few other things shooting for 1000+whp so both cars are out of commission. Luckily a friend is out of town for work and let me use his truck for a few days until I get this stuff fixed.

it looks like a revise pulley ....

Sorry to hear your bad news, Hope you get it sorted out quickly.
I think this kind of supercharger pulley failure should be known as the "Weed Wacker"

Annnnd that is why I am running 100% OEM pulley setup with a tune. My crank pulley shreared off last year. That was the last straw for "HP" mods for a while.

That sucks David. I have an extra set of oil cooler lines if yours were damaged.

urbamworm

Thanks, the oil lines are fine, just the face of the housing got dinged up and then the bolt broke off inside. I could probably drill and tap it and it would be fine but I just want to replace it. Going to put my stock supercharger pulley on too, tired of this aftermarket crap causing issues. I had a crank pulley come off too and sheer the keyway. I put the stock crank pulley back on after that and did the supercharger pulley, but now the aftermarket stuff got me again.

Damn, that sucks. 1st I'm hearing of this...so have a lot of others had similar issues with these pulleys?

Shifter

I thought you were putting on the weistec blower?? Saw on SM. No?

Luxury4play

I just installed a EC pulley. Do you know if yours was the revised version? I ask, because if it WAS a revised pulley ill have to make plans to swap mine out with a solid pulley (no spring bars to break). hopefully yours was the first batch.

JoeNobody

Was your crank pinned with the crank extension? What size pulley? I'm about to change out to stock supercharger pulley with 180 crank pulley

lm7

Yikes, who was the supplier? And like others have asked is this a "revised" version. I know we all "mod" with a risk but I don't know man our platform's aftermarket is plauged with faulty stuff. Can nothing be even reasonably reliable even if more expensive?

HeissRod

Threads like this are exactly why I shy away from upgraded pullies; be it crank or s/c.

uraberg

Sorry to see this happen. Definitely a point in favor of a fixed pulley though...

iTrader: (2)

definitely sucks ,,, did it explode under extreme RPM's or just normal driving ? and as others asked was this the newer revised pulley ?

blackbenzz

I'm really sorry to see this happen to you. I tried to warn you guys and tell you all that you are the guinea pigs if you buy his products. People just wanted to label me as a hater with an agenda. And he would have my posts deleted and tell the moderators to give me bans/warnings. Well unfortunately you aren't the first victim, nor the 2nd or 3rd. Let me guess. He offered to send you a replacement pulley

Let me know what parts you need and I can look and see if I have it. Free of course. I'm not trying to take advantage of forum members like some.

They all come from the same place.

Man this is suck's bro.. Sorry to hear, hope you get it all sorted. Kinda scary now to think of it

Dave,

I had two SC pulleys let go on me. No major damage as I caught it before they popped off. First one had bad bearings and the second was grinding something creating a dust around the shims/magnet.

I threw the stock one back on and never had another issue during the time I owned it.

Hulk

I had a few break but they were the old versions and also got some damage. The new revision has been good for a while now.

urbamworm

Haha, that was me trolling. I found a pic off the internet for that part. Pretty convincing ha? The car broke, that is why it was apart.

urbamworm

I can't remember exactly what the differences were, but I remember a while back after a lot of them started failing there was something brought up about a "revised" version which I am pretty sure after looking at mine it was found to be the newer "revised" edition. I can take another pic directly from the front if someone wants.

Thanks for the offer, I already purchased a used oil filer housing off ebay for $150, the only one I could find btw after checking with local parts stores, onlline parts places like rock auto, car-part, amazon and ebay. A new thermostat housing (comes with thermostat in it) purchased of ebay for $88 and I haven't found the rubber hose yet since I am not sure what it is called.

And to all the other people out there, I believe I am correct in saying this that a forum member/vendor had a company local to them in Texas called ASP make these pullies and then sold them themselves and had other bigger name reputable businesses like Eurocharged sell them. I am not pointing fingers, just putting it back to stock pullies and moving along. I care more about about reliability than speed in this car since it is my daily driver and like I mentioned earlier, I have a CTS-V that had 850whp and now will be getting over 1000 when I get it back in a few weeks. So that is my play toy, and the E55 is still plenty fast with the headers, 78mm throttle body, cooling mods and stock pullies. Just need to get my tune adjusted.

Oh and the pulley broke with me accelerating and I would say I was at about 60-70mph. I had pulled out of my neighborhood on to a main road and took off for a quick little blast.

Pufftrees

Wow, thats the third one in 2 weeks (mine included!).

My SC pulley snapped and blew through the top just like yours, almost same looking picture. The only damage to the engine was the breather hose and idler pulley.

Can't believe 3 people all had pulleys snap so close, everyone check your pulleys damn.


I ended up ordering a full new set of idler pulleys, sc pulley, and belt wrap kit and now its all kosher...

Good luck man, sorry to hear.

02C32guy

This really stinks. I wanted to go the SC pulley route, but I'm going to wait until this is sorted out for good.

I put 100k miles on the Code 3 pulley in my C32 without any problems at all. I shipped it to a forum member in Scotland when I sold the car and now he's putting miles on it without fault.

berti_00

there have been many revisions not sure whos getting what...
