FYI, after hundreds (thousands?) of miles the belt shows no sign of duress from running on the ribbed side of the pulley. Even while burning up the supercharger the belt hung in there!
Bet I show up in St. Louis still running the same belt!
(unless of course it gets replaced with this set up!)
Where/when do we order???

Re: Pulley Saver Kit
Ok, so I haven't taken dynamics/mechanics in like 10 years, but this is more of a common sense question regarding this kit.
If you increase the distance between two pulley AND keep the same force/tension isn't there more slack in the belt. attached is a drawing to depict my question, if two people hold a rope, and move farther apart they must pull harder to keep the rope tight.
If I am correct with this, wouldn't this mean that even though there is more "wrap" around the pulley there is more slack/opportunity for slipping and belt hop because the gap between the pulleys has been increased.
I may be wrong, that's why I am posing the question.

Steve

Re: Pulley Saver Kit
The reason it takes more effort to keep a rope tight is because of the stretch in the rope and the effects of gravity on the extra weight of the rope. As far as it affecting the belt and what would be referred to as belt lash, it would be negligible because the long section is before the SC pulley, not after it. Think of a belt-driven motorcycle and how one side is tight and the other isn't. Same thing here only with a lot more pulleys.

THe approach position of the belt allows more of the belt to wrap around the pulley. The tension side of the belt is on the right, to the left is the slack side of the belt. Greater contact to the s/c pulley gives you to have a greater contact patch to transmit torque. The effect is an unintended benefit and not a "feature" of the Pulley Saver approach. Larger idlers and longer belt to accomidate them is the deal to slow down the pace on the idler bearings, reducing heating and stess........

Now that was a good question Steven, does anyone else in the classroom have another question before we put our possessions away, while prepairing for the recess period to begins?

Re: Pulley Saver Kit
I understand the benefit of the kit (reliability, any extra performance would be bonus), I was just curious b/c belts stretch as do ropes and chains. The longer the gap, the greater the tolerance for stretch, I deal with this with cables at work. I was curious regarding where the "slack" would be, and the impact. I get the bike example, I just haven't seen it in this type of application (so many pulleys).

Save your bucks and buy the 178mm pulley and the kit together!
Re: Pulley Saver Kit
ok, kits on the site...
Product Category Listing
going thru everyone's PMs now, sorry for the delay on those
we were going to do 178$ shipped but i was having problems getting the webstore to do a set shipping rate. i instead changed it to 170+fedex. if shipping goes out of whack for anyone let me know and we can adjust it for you.

Re: Pulley Saver Kit
I am seriously thinking of selling my C3 pulley and going to the 178 crank. I have only had the pulley for about a month and think it is great, expecially once I got rid of the belt slippage. I however like the numbers the 178's are pulling and the money from selling my pulley could help.... decisions, decisions
