However, Factory SC pulleys have are not failure proof either. My OE SC pulley on my 2003 SL55 self-destructed at about 50,000 miles (which was why I created the scattershield for the M113k in the first place).
I think it is important (for everyone, whether running aftermarket or OE) to routinely inspect the SC pulley for signs of cracking on the springs. If everyone did this (and replaced the pulley when signs appear), we would hear very few stories of catastrophic failure and the scattershield wouldn't be nearly as necessary.

The welded ASP pulley's, when properly installed, are the safest route if more boost is desired. I wouldn't touch an aftermarket SC pulley with a ten foot pole. I have had the factory SC pulley bearings go out. Replaced the pulley at the dealer and no issues since. EC does not make those SC pulleys, AFAIK, they simply resell.

Out Of Control!!
Can't argue with any of that. Failure rate IS what's important. Aftermarket upper (SC pulleys) do not compare well to factory uppers (though they seem to be improving) ...

Damn, factory and aftermarket pulleys detonating? Maybe you guys should just up your cooling and go with a Fixed Pulley. Running a 77 FSP and it drove nice with a canned tune prior and really really nice after dyno tuning :-)
Personally, I'll avoid both clutched pulleys because of this thread and crank pulley because of the weight and risk of sheering it off. Not worth jacking up the most important mechanical piece in the car.

I've seen several cars totally shell their motors with a fixed pulley. I'd rather have a clutch spring break vs my motor blow.

That's why you increase your cooling. Hell, running more boost (which is why most of us are here
) you need to increase your cooling anyways so why not just go fixed and take the risk away from running a pulley than can grenade, is heavier and keeps the SC clutch in the loop.And personally for me, I'd rather not mess with the crank pulley due to it's risk of falling off. I know there are fail safes against that as well but it's still adding weight and once you want to go 180mm+ you have to change the waterpump pulley anyways. Right now I'm running a 77mm FSP with a dyno tune. Need injectors soon but it's not unsafe with the tune on it.
Also, a lot of people state that it increases heat. It will run about 10* hotter than a clutched pulley because the pulley is constantly forcing hotter air into the throttle the Intercooler. But you also don't have to run the resistor either and the bypass valve is open so it's not much worst than a clutched.
I will say I have run it with the resistor in (clutch and bypass locked) and that was when I was using a Heat Exchanger in the summer months. It was nearly impossible to keep the heat under control at a stop, I think that is most people's experience with a fixed pulley.
Either way, just my .02 Sorry to the OP about your problems with your pulley. I know Eurocharged is a good company and haven't steered me wrong. But in all business you're gonna have happy and upset customers. Hope it all works out

exactly. The UPD upper pulley with a shield is probly the safest route. That or you could order a pulley from DTK and attach it to your stock clutch by putting in new rivets and that will have the same reliability as stock (which again stock reliability on that upper pulley isn't great either)

Would love to see proof of this, a mods list and not just hear say. And for the record running a fsp with inadequate cooling is a risk. I ran an 80mm for almost a year with just methanol spraying and it was fine in the summer heat in VA. Didn't see IATs over 140* on 130mph pulls in 100* heat.

DTK makes a pulley that is just the pulley & no clutch. You have to attach it with rivets to the oem clutch. Comes in lots of sizes not just 77 & 83. He supposedly is coming out with a version soon that has a clutch attached to it. UPD to my knowledge is the only one that is the complete unit with a clutch at this time.

A fixed pulley will grenade your engine if you have 0 cooling and run it with the resistor/clutch locked and decide to not monitor your IATs. There is a risk, but in comparison it's far less risky then getting a clutched pulley and having it grenade while on a run and ripping your engine components apart. I mean the only reason I brought it up is because I know it works, I run one. It has no failure points (solid piece of metal) and the only way it will hurt you is if your IATs get over 230*.
And for that to happen your IC pump either has to die or you have to be hammering your car in extreme heat repeatedly. And finally, you have to be foolish enough to know these things and ignore them.
Exhibit A, my intercooler pump died this past fall and wasn't flowing while I had my 80mm Fixed pulley, I was using just the factory heat exchanger, and this was while I was commuting home from DC in stop and go traffic for an hour. And my engine STILL DIDN'T BLOW UP! Stop acting like these pulleys are deadly. They're awesome, why they hell do you think no other supercharged vehicles have a clutch?
