Yay to US41!

No, I am running a stock software.

Would you post some photos of your shredded belt?

TopGun32

guys,

just returned from a quick weekend getaway down in San Diego.

I have checked my belt.. and no signs of wear or tear.

I drove the car hard on Thursday after my install.

But Brandon did tell me about the grooves and with time the grooves will be less aggressive due to the constant friction of the belt.

I would say.. just take it easy for a few days with a few hard runs .. and keep checking the belt.

Anytime you add a bigger pulley or smaller pulley.. you always start checking belt wear.. just part of the game.

Cool...Dyno when you can...

c32used

Cool...thanks for the info

c32used

I will most likely have the first videos up and will share...

Brandon call UNI up and have them find out where the filters are. Tell them you have angsty customers!!!!!!!

I'm thinking the pulley is going to win that battle (at the expense of the belt). Especially given that the pulley grooves have gaps, kind of like a thread tap. As the belt inevitably slips, if the grooves are too harsh, they'll take it out on the belt!

Too early to tell, of course, so I urge all the early adopters to put many miles on their vehicles and please report back!

I'm with you Fifth. I am VERY familiar with blet slippage on my Whippeled stang, and it WASN'T grooved, aka gapped. Anyway, let's let the milage tell the tale.

See yeah

Let me ask this. One of the reasons I did not go with the crank pulley was the fact that it appears to me that the larger pulley will "overdrive" all the other pulleys, including the supercharger (which is the purpose of course). With the crank pulleys, have there been any issues of:

1. Premature wear of belts??
2. Premature wear of other components?? (such as alternator, AC etc???)

Also, will the Code III pulley potentially increase the speed of the other components attached to the Serpentine belt just like the Crank pulley does?

So far, the Code III pulley and belt are holding up over the weekend, BUT I didnt drive it much with the weather Sat and Mothers's Day on Tuesday. I will continue to keep you all posted.

MRAMG1

I can answer a few of these:

1. Premature wear of belt. None that I have seen of, or heard of on this fourm. Inlcuding mine which I just finished road racing.

2. Premature wear of components. Often talked about, but no one has ever come forward and actually stated it. It does make sense that as they are spinning faster, henece there MUST be added wear. Alot of speculation that they can handel this slightly faster RPM. No hard evidence has ever been given one way or the other.

Code3's pulley, negative ONLY the supercharger is spinning faster, NONE of the other components speed are affected. Main reason for people choosing this approach I might add. Oh yeah, simple instalation to boot. If you ever try breaking loose the balancer bolt, EAT YOUR SPINACH FIRST.

Hope it helps, see yeah

With the S/C pulley being smaller in diameter it can not over drive the other accesories, however if it were larger than stock, it will. Technically, I would think this S/C pulley might slightly balance the the overdriving caused by the larger crank pulley. You would have to do the math to see the difference between the two pulleys to find out how much it would balance the two.

AdamsSLK

Sorry, that's not true. The component that determines the linear speed of the belt (which determines the rotational speed of each component) is the crank pulley. That's why changing it out speeds up the belt. Leaving the crank pulley the same will cause the linear speed of the belt to be the same, regardless of the diameter of the pullies on each individual component. In other words, changing out the SC pulley alone will not affect the speed of the belt or any other component in any way at all.

calimax

ahh, thanks for clearing that up.

Code3 Performance

Once the pulley cuts wear in, its completely a non-issue. Its not like we leave them sharp like a knife anyway. The pulleys are tumbled to soften the edges, then the cuts are hit with a wire brush. I have over 4k miles on my current belt, and it looks new. The current belt was brand new. The last belt had 4k miles on it as well, but it had over 30k miles total before it went on. MANY pulley manufacturers use non-slip cuts, this is not something new we came up with. We will be changing the shape of the cuts for future pulleys. Non-slip cuts do work. There is not a lot of information floating around about them, so we had to do the testing ourselves.

I have considered not using the cuts anymore. Some of the dynos posted are with a pulley that had no cuts. Perhaps I will simply make it an option. Honestly, I have a new size idler pulley I am testing this week. Its job is to return the belt to perfect tension, as well as add some more wrap to the SC pulley. This is a new middle idler. Its a one bolt piece that takes an extra minute to change when everything is apart. It is a cheap pulley to make.

Needless to say, I have spoken with almost all new pulley owners, or heard from them. Except for the one incident, everyone else is completely happy with the pulley performance, and no one else is having any belt issues. This includes multiple people running both a crank pulley and sc pulley.

TopGun32

lets give it some time.. to make any judgement on the "no slip cuts"...

while for some it might be an issue.. but please don't rush to judgement.

If we start seeing a few handful of issues.. I'm sure Brandon will have them refinished for you to provide peace of mind.

But right now.. there is NO need. The pulley works.

The good thing.. the pulley works and its only the beginning. So far the mystical clutch pulley has been solved.

c32used

I have yet to read a thread about that on crank pullied cars but then again I wasn't around when ASP, RENNTECH, EVOSPORT OR KLEMANN...started so there may have been at first. I have read about ASP pulley breaking cause of the weld points in it introduction(but could have been with the E55 guys with alot more mods). I defintely feel buyers should post/PM their problems or excitment over this new product so people like myself that are interested can become familiar with possible issues so they don't freakout and just give it time and avoid install problems.

c32used

I say by coming on here its better to PM instead but it may provide answers to the concerned or solution to the next buyer IF an issue arrises...

Its not that mythical, just for us MB owners, The Buick GS guys have been using the smaller supercharger pulley for years.

AdamsSLK

True; I'm actually a former owner of a heavily modified Pontiac Grand Prix GTP, which used the SC'ed 3.8l pushrod V6. There is (or at least was) a company that produced a replacement SC snout and pulley plate that allowed for different sized SC pullies to be installed very easily. The difference, however, is those SC's were not on a clutch mechanism of any kind. If the crank's turning, the SC's turning.

TopGun32

exactly..

Its not mystical by all means.. but some said it could not be done or work.

I had a bearing failure on a used set of Evosport pullies.

The water pump pulley bearings failed due to excessive spinning and broke my water pump cover and busted my belt and I was stranded. It was a $900 hit in my pocket book.

Evosport gave me a new water pump pulley but did not cover any of my expenses, towing, materials and time.

Why..? I bought a used set of pulies and it comes with the territory.

The new water pump pulley was designed with better bearings to withstand the punishment. I had the older design.

Hence the reason I sold my ODSP for $400 and returned back to stock.

Interesting... so the one accessory-issue on a crank-pullied car (that I'm now aware of) is from the ONLY kit on the market that is specifically designed with extra pullies so the accessories are driven at stock levels. Kind of ironic, when you think about it...

c32used

Sorry that happened to you...did you do a prior write-up about this issue you had? Because its first I heard of this....Just like the S/C pulley had an issue possibly I can see any crank pulley having an issue also....but its not that common by what I read or as you stated about yourself. Every new thing will have some failure in it but its only one thus far and there might be a valid reason to why not the products fault...but lets see what all say cause that will be the average maker....
