I'm looking to do this mod and just wondering who has done it and any feedback you might have. Thanks all-

i was also wondering if the belt wrap kit replaces the idle pulley near the sc pulley. it looks like it does from the pics. I need to replace my idle pulley but i figure i might as get some extra poweer out of it if it replaces it anyways.

Jturkel has one, see this thread:

I have it done. It is a very very easy install. It basically eliminates all belt slip by increasing the surface area that the belt comes into contact with. it is good for about another .5lbs of boost or about 7-10 whp. I have not personally dyno'd it, but those are the claims made by Code3 from a dyno. It also seems to shift faster under WOT conditions. Furthermore, the supercharger responds much faster when engaged under WOT.




As far as pulleys that it replaces, the belt wrap kit replaces the upper guide pulley, the middle idler pulley, and adds another pulley where the alternator pulley is. definitely a noticeable difference in feel. 7-10 whp may not make your car much faster on the street, but you can definitely feel a difference when driving.

yes i do!

TemjinX2

so basically pulleys 6,5 and 7?

jturkel

5 is the s/c pulley. that stays the same. 7 is the alternator pulley. that also stays. an additional pulley is added down by the alternator. i will upload pics in a sec....

TemjinX2

sorry i meant 4, good info...pulley 6 is starting to make noise. So i need to replace it.

trbo2nr

Thanks. I'll check it out.

trbo2nr

Thanks! Great information.

jturkel

this thread will be more useful. there is not much mentioned about the wrap kit in that thread.

pics can be seen here:


this picture shows the new wrap of the belt. the upper guide pulley is replaced as is the middle idler pulley. as you can see, the the upper guide pulley bracket is maintained.



this picture shows the location of the new pulley that is added in place of the alternator bolt

I'm guessing this is for the code3 pulley only? since the code3 pulley has an overall smaller surface for the belt to grab onto causing the belt slip.

jturkel

yes....and those who want to run a 178 with code3's new midsize s/c pulley

kevkranker

Good info jturkel

FrankW

the LET 178 or the Evosport 178 because Evosport has many more pulley in their kit. since I've been wondering if the code3 would just go on if I already have the evosport kit.

TemjinX2

great info jurkel. Replacing the stock idler's pulleys with oem costs around $180 anyways, so $200 for new pulleys and a addition 7whp is pretty good deal. I need to save, spent way too much on the car this month.

jturkel

agreed. i am thinking about selling my code3 pulley and wrap kit as i am leaning towards switching to the 185. if you are interested, lemme know.

LET makes a 178? i didnt know that.....it is made to run with any 178 because they are all the same size (at least roughly). so i believe the 178 is made my ASP, Evosport, and Renntech. So any of those should work. The wrapkit is helped to reduce belt slip when running a stacked setup of a 178 crank pulley with code3's new midsize s/c pulley (not the one that came out like a while ago).

thanks!

LET never made a 178mm CP. 181mm, or 185mm.

You might've been thinking of ASP.

Jturkel - thanks for sharing the pics... definitely helps visualize the new set-up; lookin' good!

SRTpowa

Check my sig, I'll be sure to let everyone know when I get mine how it works with the ASP 178.

jturkel

yes please keep us informed! the dynos for the stacked setup (which i have seen) look good for the 178 + midsize + beltwrap!

c32used

Newzchpsy has it also. I thought when I spoke to Brandon from C3P that he said it worked also with other pullies like 178,181,185. OP how are the accessories working? I heard thou it's a good mod that is causes more wear and tear on accessories.

TemjinX2

PM me the price on the belt wrap kit and when you can have it available. If my pulley project works out, i'll definately need it.

jturkel

eh....i havent heard that. i think Jake was telling me it wont work with the 185 because it adds to much stress at some weird angle or something...i dont recollect....it might work on just a 178, but dont quote me on that.

kevkranker

Why would it cause more wear and tear on the accessories? There wouldn't be a change in speed that the belts move. The crank pully is the same size...

c32AMG-DTM

+1

I don't think it would cause significantly increased wear of accessories (i.e. no more than the other 178mm kits available). The larger the CP, the faster (and consequently, more often) it's turning those accessories... if the other pullies are not changed out to larger variants as well.

What I would be curious to know... if it causes any appreciable additional wear to the belt itself. That bend around the S/C pulley is pretty severe - the added benefit of reduced belt slip and increased responsiveness may be traded off with increased belt wear and more frequent replacements (IMHO, not really a big deal, it's an easy change and a $60 part). Time will tell... looks promising, however - nice to see new innovations as they pop up.

Brandon recommended the Gator back belt for this setup(178+mid) so I went with that. Said they had this setup on a couple test cars for 6 months without issue. I can only hope it is as good as what I have been told.
