After work yesterday I went to pick up a pizza for dinner. Leaving the garage I turn on the A/C and I heard a squeal as I accelerated from the light. Picking up the pizza I get back on the main road and that nasty "thup, thup, thup, thup" noise came up!
I pulled into a side street, popped the hood and saw the Dayco belt had jumped over one rib away from the engine. I had to turn on and off the engine so that I could cut off the separated rib before heading home.

I'm not sure why it would have jumped when I already have my washers in place unless the blower or mounting plate had loosened. This time I added more of that permatex stuff on the threads for good measure.

At least I did the hard stuff last night. All thats left is tightening the belt and putting the piping back on.

On a side note I was wondering if one of those HKS green filters would fit on the blower?

 

I'm assuming you have a V2 kit since you mention using washers. The V2 has helical cut spur gears, which means an axial load is going to result from torquing the pulley. I wonder if there is enough axial play in the shaft that the pulley is on to cause the belt to jump a rib.

 

buy a turbo kit

 

Come on Jason, don't be shy, tell us which one we should buy while you're giving out useful advice. And where's that dyno plot you said you were going to show us???

 

hey bigsadler thanks for offering to buy me one!

 

anytime bro.. hah.. anytime.

and stephen, it's out of my hands.. I can only beg and ask so many times to get things done. if my muffler gets here and my cat i will do another dyno run the full 3" at 7psi to see where I am at.

I see no reference to the "Idler Pulley"!

If you are running the Stillen SC Kit Idler Pulley then you are halfway done.

The Stillen IP will cause the SC belt to misalign with the SC pulley due to poor engineeering. A well made "Anodized" aluminum Idler Pulley plus proper pulley alignment should eliminate the problem. Also a five rib belt can be used with the belt set either inboard (closer to engine) or outboard (away from engine), and on the other pullies set the belt the opposit to the SC setting. This will adjust for misalignment in a "test" type mode.

This is my first post and I am not sure if I am posting correctly. I had expected a different format to post in.

 

No, I have to disagree with you about the Stillen idler pulley being at fault. I still have DanNY's aluminum idler pulley on! I switched it out the aluminum tensioner pulley for the Stillen tensioner because of slipping and squealing. I've used belt dressing for more grip but that was a temporary solution and I ended up spraying it on every morning. Also the belt has not rubbed up against the walls of the tensioner pulley. I've installed and reinstalled at least 3 times so far so I know where everything goes.

It will be 3 years this October having the SC. I've had no problems in my first year until the time I had to swap out the belt because of excessive slipping during the winter. The first time the belt actually shredded was when I swapped out the 3.6" pulley for the 3.33" last November (when I got new bearings for the blower ) and I mounted my washers in the wrong locations. Relocating the washers fixed the problem.

As for the latest shredding it was a hot day and upon leaving the garage and not warming up I flipped on the A/C. With a little bit of boosting tossed in I now think that the belt was not warmed up enough and so this caused the belt to jump.

 

Having a V1, and not knowing how a V2 works exactly - I have a question.

Are the washers needed as a funciton of the bracket or the blower itself?

From talking to Vortech today, the V2 blower is exactly the same externally as the V1.....this correct?

You should make a drive down here, BlackCat - we'd love to see ya, and I could take a look at your setup and maybe lend some advice, or at least give you another set of eyes to look things over.

NWMaxima.com BBQ October 9th....

From what I've heard, the housing and the impeller are the same. The difference is in the step up gearing, which are helical instead of spur gears, and with a 3.6 step up ratio instead of the 3.45 that the V1 uses.

 

Hey Ian! Are you talking about the "Official Second Annual NWNISMO BBQ"? on Oct. 4th? I'll have to check with the wifey....

The washers were put in by the speed shop that initially installed the SC. I only discovered them when I took apart the SC to replace the pulley and belt and although I was careful to note where everything was placed I missed the washers as they dropped off the posts. The washers just act as spacers in order to align the belt with the idler and tensioner pulleys.
Love to take a look at your setup and see what more I could do. When I swapped out the belt again I thought of getting a 3.25".

 

We are going to that BBQ also, but I was more discussing the NWMaxima.com BBQ. You need to go join NWMaxima, by the way, if you haven't already.

I see about the spacers...weird. It should line up by itself if installed correctly, shouldn't it?

If you wait 6 months, I'll probably have a V2, Aquamist, 300z Injectors, and a 2.87" Pulley.

 

Huh? Going to a V2 now? Not happy with the V1?

I guess not all motors are in perfect alignment from the factory and so the washers come into play.

I was thinking of the Cattman headers for next year. How about you?

Isn't the Aquamist for intercooler use only? Are you planning to install it right where the compressed air enters the collection tube?

Hey! Read the posting in NWMaxima and it said Sept. 13th. Thats my auto X day.

 

Mostly the fiance can't stand how loud my V1 is, and would like me to change it. There's also some slight suspicion that my V1 isn't boosting what it should.

So I'll be taking it off anyway to have it rebuilt, because it's got 60k on it anyway - even if that's not the problem, I may as well rebuild it.

And if it's being rebuilt, I may as well make my gf happy and get a V2. I put a post in the FS section for the trade.

Uh - October 12th. Look at the very top post in "Meets and Mod Days: - Announcement: MEVI's arriving - BBQ and maybe a movie" - it's at my place. They just put in a HUGE BBQ on the 3rd story garden of my high-rise, directly under the Space Needle.

No - you don't need an Intercooler/Aftercooler to have the Aquamist - At least I don't think you do.

 

Ohhhh Oct.12 works for me but I have to check with the wifey as its our Thanksgiving weekend up here.

 

Heh - Crazy Canadians and your strange holidays.

 

yes, veddy much British influence up here!

 

Uh-oh. Once you give in on that, then the next thing is "wouldn't it be more practical to have a new mini-van instead of this old car?"

 

Maybe you shouldn't have mentioned about the V2 to her and just said, "..but honey, its not broke! thats just the way it is!"

 

Yeah - she overheard my friend and I talking about it.

Of course, she also thinks the SC only costs $300.

Heh heh. So I'm not the only one hiding something.
