New guy here.

I also had a friend that had a similar problem with the upper pulley. He did not try to correct the problem himself, he did have to send the blower to a machine shop for removal.

 

Hey Armand,

I went with the lower pulley from PSP. W/o the tool it's 200.00 and you don't have to worry abiut the issues arriving with upper.

Just my .02

I was simply adding my input on my experience with an upper pulley. The topic is about upper pulleys, not just the METCO's. The METCO pulley is a great design, and will save a lot of trouble and make it an easy swap. But I still believe that a smaller upper pulley Des not have enough belt to pulley contact patch to keep it from slipping on the high RPM's. Just my .02 cents worth
Since I have been around here so long, I was just trying to help out you new guys, and not try to direct them away from any choice or persuade them into buying ours.I feel it's always good to have ALL info when a choice is to be made,especially one like this Thanks

Totaled, glad to see your amazing times!! Although I am a little jealous about your truck being stronger than mine.
These are my thoughts on pulleys:

JDM's pulleys (which have yet to arrive after months of "they will be here next week") seemed the best because of Jim's attention to detail and the use of the spider cage so the techs at ford might not notice the change.

PSP's pulley seems proven and true, but the lack of cage means that any machanic can tell that its been swapped and can at least claim the warrenty is voided.

PSP's warning that a smaller upper pulley might slip seems appealing (at first) and based on common sense. Yet, I have never seen anything to back this claim up!! Remember, PSP said for over 1 year that additional boost would destroy our superchargers. Then, PSP admitted that this was based on "theory" and that it was wrong. I admire PSP's honesty and believe in many of thier products (PSP's chip rocks). But sincerely, my question is, is PSP's "slippage" suggestion a "theory" or a fact?

Totaled, I have perosonally met you on numerous occasions at the track and you certainly appear to be a conservative and fair minded person just searching to improve your vehicle (first the Z06 and now your L). I think that I will now consider the upper pulley exchange. If nothing else, for ease of swapping back to the stock pulley in case I need to bring it in for warrenty work. Hate to have the dealer refuse to exchange my intercooler because I swapped pulleys!!!

Jag,
I think your getting my advice confused. This is not PSP's words. THOSE ARE MINE

I am just trying to help you guys out here. I think your just assuming I am trying to direct people into buying a PSP pulley. Then thats your choice, common sence and past experience tell me what I need to know. Thanks

 

Jag, you are correct about the belt slip. It is a theoretical problem, but not one that could never happen. It's just common sense. You have more of a chance of belt slip with a smaller upper pulley than a larger lower pulley. When it finally does happen to someone, when will it be? It could be in the final round of a huge event, what if that happened to you? I sure woulnd't want to chance it .

Two years have gone by since the Gen2s came out, and many people seem to be forgeting the reason people stopped using the upper pulleys. It was not belt slip. It was blower snout damage. I know of at LEAST a dozen people, myself and Spiro included, who had to replace our blower snouts due to damage from doing the upper pulley swap. Some people say they have the "right" tool to do it. The right tool is not the one the pulley maker sells. Only Magnuson and Eaton have the "right" tool to do that. The rear snout shaft bearing is on the inside of the front of the snout cone, and you need this tool to properly support this bearing. These "quick change" pulleys are just as potentially damaging as a regular upper pulley. You still have to take the old one off and press the new hub on. Nothing has changed except for a neat idea.

Don't get me wrong, many people have installed upper pulleys with NO problems at all. They are the lucky ones. But many people have also had to replace thier snouts from trying to install an upper pulley. The clearances vary. Some come right off, some don't. The problem is you don't know if you are going to be lucky or have to replace your snout until it's tool late.

This in not new information. I am just bringing up issues that have been buried in the past and forgotten. Now that a new upper pulley craze is on, people need to be reminded of the potential problems. This information was out way before there were any lower pulleys.

Hey Jeff, how have you been??
Had the L on the Autobahn yet?? Miss you at the track - have you went out for groceries over there
Yes Mark will refund your money in the event you cannot remove the pulley. I am no mechanic (as you know) and it took me 30 minutes to remove and install the new one! What really amazed me was after reading all the horror stories about the upper's was the ease in which the orginal came off and the new one went on The refund policy was a critical purchasing issue for me!! I asked Mark if I installed the upper pulley and my engine made the same loud rattling sound that occured with the PSP lower pulley could I get a refund and the answer was YES Fortunately it was silent. Has anyone heard of problems with the Metco design or all the problems with the ASP's?

Mark asked me to post this up "When the pulley kit was being designed Metco & LightningForce worked on it. Only because of a business decision does it have Metco name on it. It actually cost less to get the kit from Mark/ LightningForce "

 

Hey Timburntire---Long time no hear.So, you like the PSP? No noises like Totaled had? I'm leaning in that direction.BTW still interested in the 95 L? I need to sell it NO MORE ROOM for my toys!!Contact me for a great deal. C-ya!

 

Thanks Sal, your advice certainly sounds well reasoned. And please, don't get me wrong, there is nothing wrong with "theories," after all, I don't have to rev my engine to 9000 rpm and blow it up instead of theorizing that if I do so I will ruin my engine!!
Damage to my upper snout is definately a concern. Totaled, how did you get your pulley off and will Lightning Forse refund the money in case we cannot get the pulley off and need to return the pulley?
