Yes, stock cats. Timing is 15-16 degrees from 3-7K rpm. AFR is 11.5, 8.4 max psi. Seb is NOT finished with the tune yet so there is probably more power to come with him dialing it in. I'll be doing another log run either this evening or tomorrow. We have been having a bunch of pop up thunderstorms in the afternoon which is quite common for us this time of the year. I may and wait until tomorrow morning when it is cooler and less likely to be wet. BTW: I did contact Gates about making a 7 rib 109 3/8" belt so that we could use the additional idler on the jackshaft drive AND have the proper width. They can do it but the setup fee is $10K and the minimum order is 100 belts. Ouch!

Damn, I will stick to my 6 rib belt. Been driving the car every other day and have had no issues with it. The only thing I get is no belt slip.

Nice job on the research of the belt. But yeah, thats not gonna happen. [QUOTE=Pauly Z;3534984]Damn, I will stick to my 6 rib belt.

I mean, you did pick up a whole psi so it has to be.

I'm going to try the six rib belt too. Ordering it now. Gates K061098

Pauly Z, if you could supply me with the info on the 2 inch pulley and what type of bolt / spacer is needed to use the 6 rib belt, it would be much appreciated.
Did a leak test this morning and when I got to 7 psi i did find one leak. It was at the joint where the 2.75 coupler is trying to clamp down on the 2.5 J pipe. I tightened the crap out of the clamp and got it to stop leaking. So then i took all of my solution back apart to try and get the 45 degree coupler to work. I probably should have just kept it together. Trying to get the darn 45 degree coupler to work is not working out. From what I have gathered from the pictures posted I need to push the J pipe in as far as it will go in order to keep the coupler from collapsing. If I push the J pipe far enough up into the 45 degree coupler to keep it from collapsing it is then too short to reach the BOV coupler. I just don't understand why you guys can get this to work and I can't. Very frustrating.....

I understand how annoying it can be since it took me a good 3+ hours to get mine in position. Can you take some pics? Did you try using hump hose couplers btw? Sent from my SM-N910V using Tapatalk |

Sorry but I'm not spending any more time with the 45. I have spent the past four hours trying to get it to work but the J pipe is just way too short to reach.
I'm going back to my original solution which was working. I'm using a 90 degree 2.75 then a a 2.75 to 2.75 coupler to extend the J pipe and then a reducing coupler (2.75 - 2.5) to get to the J pipe which is 2.5. It worked before. The only thing I can think of is that I got an incorrect J pipe.

Just made another run to check on the boost issue and no difference. Looks I have a belt slip issue though. The boost builds pretty linear up to around 6K rpm and then it is flattening out. At 3700 rpm boost is at 1.16 bar (2.32 psi), 5175 rpm 1.31 bar (4.5 psi), 6300 rpm the pressure is at 1.44 bar(6.38 psi), at 6775 rpm it was at 1.48 bar (7.2 psi) and when it reached 6950 rpm the pressure had DROPPED to 1.37 bar (5.37 psi).
I was going to use some of the CRC belt dressing to see if it would help and then the rain came. Looks like it will be here for awhile. If it dries up before dark I'll try the belt dressing otherwise it will have to wait until tomorrow.

Can you take a pic of the top of the supercharger? If the volute isn't rotated enough then I can see how the pipe would come up short.
And yeah you should not be going negative in higher rpm bands. But with a new belt and the same setup as most I'm not sure how you are getting that amount of slip. I can see how it would stop building boost but loosing that much up top is strange.

Here is the picture you asked for.
I don't think the clocking of the volute can be the problem because the J pipe is at least 5-6 inches too short to work. If I connect it to the BOV coupler it will barely reach the 45, not even enough to get it deep enough to be held on by a clamp much less keeping the 45 open during the bend.

No that's the problem. The volute isn't clocked right. Clock it per the instructions sent and it will fit like the rest have fit.
Way up at the top of the L pipe where the coupler is, is the fulcrum of that pipe position. If it is turned off the volute 1 inch then that translates to 5 inches at the connection point to the coupler. Its like taping a straw to a quarter. Rotate the quarter a half inch and watch the other end of the straw move 10 inches. It really has to be installed correctly in order for it to work.

I was the first to get this kit from Topgunz and just wanted to update everyone. My car is still running very strong and have had 0 problems at all. We worked through issues when I got the kit to get everything to fit and function correctly. When installing this kit, you need to follow the instructions to the T or the kit will not work right. This includes using the supplied couplers, tubing, and trimming out the pieces on the car that enable each part of the kit to fit. The kit isn't going to fit perfectly at first because no kit ever does. It takes time and patience but in the end you will be more than happy that you took the time to install everything correctly. I have nothing but great things to say about Aaron and the kit and how this kit has made my car a different animal not only because it added much more HP than the original setup but that it made my car much more safe to drive. So for all the skeptics and non believers you are missing out if you do not have this kit. It has 0 issues if you install and take the time to do things right the first time. This isn't directed towards anyone at all I just wanted to give my input since I was the first to get the kit. If you are having problems with installing the kit, don't get upset and just continue to work towards getting it right. We are all here to help and if you have a problem I'm positive someone will have a solution to help you get it right.

Right now I am focusing on the belt slip issue. Hopefully Pauly Z can get us the parts list we need to add in the idler and longer belt.
