Too many bad pictures of things flying man........;)

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Dude I so did this and it's working! This works better for me for a few reasons.

1. It eliminates the "lathed" down pulley or running on the back side of a pulley.
2. With my setup the belt/tensioner was nearly at it's tightest position. This is more comfortable.
3. Provides enough belt wrap so that I haven't noticed any belt slip (yet).

I spent time behind the Autozone counter and could not find a suitable smooth pulley but this works so I don't need the pulley!
Thanks Ryououki! :p

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

I agree. Great work Mike. Almost looks as good as mine :rolleyes: !

Of course I can make them faster than you can. All I have to do is speed up the engine! That will make things fly even faster!

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

thanks Mike...your replacement is on its way direct from Rock Auto. Let me know when you get it and if I ordered the right one...the part #'s from tighed original post, didn't match what I ordered...Rock Auto's web site took me to another #.....so let me know....thanks, again...

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

The lathe goes faster too..... but dosent need to...;) be safe out there.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Glad that I actually helped out the great tighed1. :) As much as you have offered to this forum, it's nice to know I offered something to you.

Have you gotten on it really hard yet? I haven't had a chance to fully test out this configuration for an extended period.

dj you crack me up!! i looked at doing the dj way but realized this only works on the slower blue cars! my black car runs to fast!!!. thanx mike mine is racing your way!:p

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

krazy, you do realize that I have 2 BLUE SRT's right??:rolleyes:

oops! egg on my face!!:D of course everyone knows dj has been jonesin for a black srt-6!

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

So you are now (assuming everything holds up) saying to take the supercharger idler pulley off, and put it in the other location above the alternator? So are there any parts that actually need to be purchased to do it this way?

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Yep! That's what I'm saying FOR MY APPLICATION.

I did get on it and still no slipping. Works for me!

Yes you will have to purchase parts. A bolt and a locking nut.

1 - M8-1.25 bolt, 75MM long

• $0.99 at ACE Hardware

1 - M8-1.25 nylon locking nut

• $0.45 at ACE Hardware

1 - Spare washer laying around the garage

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Is there any reason this shouldn't work for those of us who are going to be running the code3 pulley alone? Is your "for my application" just a "do at your own risk" statement, or is there more to it as well? thanks!

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

bill i have mike r making my idler smooth for me and when i get it back ill be installing it and adding dj's diy wrap. there should be enough room after the smooth mod is done. ill let you know how it goes

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

well, looks like I might have the pulley before I leave for the Dragon...up for a Dragon install if I do....and I took off another .20....we are at 12.339, 112.81....my 60 ft time sucked big time...just couldn't get it together tonight...didn't have much time to hang and try again...its there last day for this year to test, so a lot of people there...but they will let me race next year in a sportsman classs...hurayyyy...oh, the 60ft was 1.795...need to get that down somehow...see ya's at the Dragon, thanks again Mike, let me when you get the replacement...

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Just sayin' works with the Code 3 and the 181 pulley combo.

Heck everything I read and do from this site I mentally add "do at your own risk" to it.:rolleyes:

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Well, I went driving around today finally. Seems to be holding up quite well. More play after work today.

$5 DIY Belt Wrap kit
 

I just did this and it works great. I only had available an M8x1.25 bolt with 70mm threaded length, 75mm overall length. Which is a tad less than I'd recommend. It was not long enough to put any washers behind the locknut, which I would have preferred.

I put two grade 8 washers underneath the hex bolt head. The idler pulley bolt hole is enlarged on this side for the original bracket and I was a little concerned about the washer deforming and loosening where it is not fully supported. One good thick washer would accomplish the same thing.

I put some Loctite red on the threads as well as using the locking nut. It's not going anywhere.

Considering how little belt wrap is around this pulley, I don't think a bracket will be necessary to withstand the shear force. I will keep an eye on it though. This simple move definitely increases the belt wrap on the kompressor. 25-30* I'd guess. The overall belt route length works out about the same. I had to fully release the tensioner to get the belt back on.

Re: $5 DIY Belt Wrap kit
 

Update:
I ended up putting the idler pulley back in its original position after I noticed some rubber wear from the belt. The alignment must have been off. I am not sure exactly where it was rubbing.

I have a 62mm supercharger pulley going on eventually, so I made need to revisit the belt wrap issue to avoid slippage. That means either figuring out why moving the idler pulley was causing belt wear, or getting a Needswings pulley saver kit.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

I did this and have spaced the pulley out with a washer to match the s/c and alt position and have had no issues...... I run the 62mm pulley presently. No slippage and no abnormal wear on the belt and you can retain the original belt!

I found this smooth pulley that looks like it might fit in place of the grooved one.

Here's a Uro pulley that's less expensive than the Dayco.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

The answer to this is buy a stock grooved pulley just like the grooved idler, then put one of them on a lathe and cut the grooves off of it. This one goes in the idler position, the grooved one goes in the new position, that way you have a setup where the belt cannot slip off. An additional support might be helpful, check my setup below.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

So the consensus is that no one has found a smooth pulley that doesn't need to be lathed down?

I don't have access to a lathe. So if I were to buy a new stock grooved pulley who would be able top grind it down so it is smooth? A wood shop, machine shop?

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Either one would be able to do it but I would take the machine shop as they would be a bit more precise.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

FYI coming up on 7 years this mod without any issues.
Think it's safe to say it works!

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Yes, that was a great idea, thanks for your contributions to the forum, you have added a lot.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Does the original first post needed to be updated with new info?

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Tried to PM you tighed1, but your inbox is filled up.
My Poland 65mm steel pulley came in the mail and I have been reading about your DIY belt wrap kit.

^^Is that a SRT-6 factory supercharger idler pulley? I searched SRT-6 and C32 AMG and that part number never came up for the idler pulley which I thought was odd.


So that is the correct pulley to order and the same one you have ran for 7 years? I noticed you made it smooth, is this necessary?

EDIT Read through the entire thread.

For one: The RockAuto part number listed does not show it being a SRT-6 supercharger idler pulley.
2: This entire thread is mainly for people running stacked pulleys. Since there was a member that tried it with a just a 65mm and the belt rubbed. Also there was a member that needed spacers.
Seems like the best bet for people with just a 65mm pulley is to get the NeedsWings Pulley Saver Kit. Not sure if that is overkill or even needed with just a 65mm pulley.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

My be a stupid question but is this mod only for under size SC pulleys or would it help a SC with a stock pulley.
Thanks

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

I think that this thread needs an update specifically stating what should be done and the specific parts for the various pulley set ups.
This might save some people grief and injury.
I read the whole post and ended up a little confused as to the correct action to be taken for an OEM set up let alone any SC pulley changes.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Me too :confused:

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

I have the parts to do this...and even the belt. I need to talk to DJ and put them all together and sell them. The kit works. I just decided to do Rob's instead on both the cars. I have the bolt, pulley and belt for a 65 mm install, but I am sure it will work with a stock pulley as well, just need get the belt figured out.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

I like your solution Tighed. Will probably go same with 178/65C3 in my SLK32 in the next month or three.
I presume your'e still running the 181/65C3?
Do you have any logged boost and/or fuel cons figures at WOT?
At a stretch do you have an AFR paired with any of the above figures?
Stock Belt?
Tune?
Stock injectors?

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Still running the DIY Belt Wrap on the coupe (181/65) and the vert (192 crank).
No logs but do have AFR meters to keep an eye on things.
Stock belt on the coupe, little longer on the vert.
Mail order tunes on both.
Completely stock fuel systems.

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Sorry Tighed - DCAI or single?

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Stock intake on the Roadster (192mm)
More Air Intake and DIY Performance Intake on the Coupe (stacked)

Re: Do it yourself DIY Belt Wrap Kit for less than $25
 

Is there a new update on the your pulley wrap. For a 65mm pulley.
List of parts needed.
And part numbers if possible.
THANKS
