[Whipple Charged]

The blower belt has a tensioner in it's path. Some claim a new belt is not needed and have no issues, others say they get belt slippage with a pulley and stock belt length. Use the search button to read the old threads.

Yes, when we first made the pulleys, we didn't see any belt slippage issues, but the tensioner was very near it's max closed position, so we saw it to be a potential issue, especially as the belt got older. So, new belt, I think it's really not much of an issue, but it will be sooner or later.

The shimming to which you speak is the moving of the power steering pump.

Thanks Shadowman, yes, this is what FRPP and Roush do and it seems to work pretty well. Does save the time of taking the belt off, but I think the shims are no cupcake to get in. Actually never installed them so I can't say for sure.

The Shadow Knows!

Very good, insightful post, Bill.....as usual!
Thanks for the clear prospective of value! Spot on.

I posted this once before, but perhaps it's time to post it again. The Ford (FRPP) pulley installation procedure is in the attached PDF file, and tells how to shim the Power Steering pump in order to use the stock belt. I don't know about other pulleys, but perhaps different sized shims could be used in order not to change the belt length.

Thank you Ralphie

There is never too much real data shared.

Certainly shims are an option worthy of consideration and yet IMO changing a belt if need be is fairly painless.

IMO the greatest advantage to the shim process is that an OEM belt can be acquired 'likely" at any moment in time; in fact maybe even through the local parts house and yet the life cycle of the typical supercharger belt is extreme so to some degree it remains a bit of a crap shoot when one considers which path to take.

I mean not to cause a riff however value and price in my world are two different things

On almost all items I too can find a lower price and yet what I am drawn to is the best value.

When one considers smaller pulleys for example; initially they were a higher priced as the cost of creating the pieces had to be factored in and then as time passes these cost have been recovered as such the potential for a lower price exist. The key word is potential because sadly and all too often another company comes to market with a me too product however with no cost to develop because they are simply copying another’s as such their ability to sell for a lower price is easy to understand.

Now if one is drawn to the lower price as a matter of practice then they all too often discourage companies that introduce new products from doing so. This is very simply because a new product generally requires front loaded cost associated with R&D and market development aka risk and if in assuming this risk another is going to be encouraged/allowed to copy it as evidenced by the consumer banging on their door then it would make no sense. As consumers we truly do guide the ship through our actions and sadly IMO being focused only on price creates the basis for many people to lose.

So many would say get a patent; sadly the very idea of protecting a proprietary/unique product or service is both expensive and can be arduous process and in the end does not insure that a like kind product will not be presented which then opens the next financial draining door; litigation.

There are many great vendors that actively participate within this forum and this not only instills confidence but IMO also adds value to their offerings.

A pulley cranked out on a CNC machine in this day and age is a few minutes enginnering to copy a pulley file into the CAD and add a couple ribs and re-size and export to the CNC and chuck up a new piece of metal. I think that is why the Metco pulley is lower cost and they seem to have years experience making pulleys and all the tools. All too many of our parts pass thru too many hands there inlies the cost escallation. All we can do is research and choose.

I forgot about this post. I was looking at a picture of the engine (I guess in Prototype dress) and did not see the belt go to an accessory. Since my GAL lives on the second deck in the garrage I had not gone out to investige directly. I think this cinches it. A pulley and stock belt! :banana

At Rally I I had the GT GUYS do the Heffner tune and pulley. The pulley was defective and did not run true. Many folks would not even have noticed the difference and let it go. Dennis and Rich worked at night so I could play with #1153 during the day. They put the old factory pulley back on, Jason Fedex'd another pulley to Dennis and Rich and they installed the replacement unit the next night. I prefer to work with folks that I know and vendors that stand behind their products.

I know I can find everything cheaper someplace else,..... but will stick with the course that has worked well for me.

The sentiment expressed by Daniel is a recurring theme here on the Forum. The vendors Dave has selected to support this site, do exactly that, they support us owners. Jason Heffener has worked on many of our cars, does meticulous work, attends our rallys and is always helpful in answering questions about his products and our engines. He turns out some beautiful cars with his products although I do not have any of his products on my car. Many other Forum participants do. Likewise the wrench turning performed by Dennis and Rich is unparalleled, in my opinion. They have worked on my car and their work was flawless. As it has been on others.

Can you find less expensive options for parts and services, most certainly. Just remember the value part of the equation. I am happy to support our Forum vendors. Totally an owner option.

heh... well it was a DynoDynamics machine so the number will seem low... 577rwhp

I tuned the car last week on a DynoJet and the car made 648 rwhp.

that is awesome

those headers must be helping :thumbsup
