There is one thing that I have gotten very good at, finishing a Z project in time for a rain storm........

August in Alabama means a 75% chance of rain every day around 4-7pm. At least the showers cool things down some but the humidity! You can work up a sweat just standing.

Well, the 8 to 7 rib belt mod and additional jack shaft pulley have been installed. I did wound up making a custom spacer out of 6061 aluminum bar stock. I just didn't like all of the washers acting as spacers, it just wasn't worthy of my Z!

The HD Fleet belt is slightly thicker than a regular Gates Micro-V so I would think twice about using one. I will, however check with the Gates racing division for the racing version of the K080188 belt in BLUE to match my Z.

Pauly Z has already posted a picture of the setup but this is what mine looks like IN RACING GREEN.

The swap out doesn't take long at all and the belt, pulley and hardware runs about $100 and it should not slip! Look at the wrap around of the belt on the jack shaft pulley. Awesome!

Tomorrow the weather is looking good in the morning so I will try another log run and see what happens. Wish me luck!

If you really won't to get a nice log run in come to Birmingham tomorrow morning. Bama GZR is having a meet, photoshoot, and brunch.

Sorry but the weather here this morning sucked. It was afternoon before it was dry enough for a test run.

TBatt · 08-21-2016, 06:26 PM

Okay, another log run and the same results! Boost starts to drop off around 6300 rpm.

This time I paid close attention to what was going on and I think I have found the problem. When the engine gets to around 6K rpm the traction control light starts flashing which I think is pulling the throttle back. I need to remember to TURN THE VDC OFF!

You can see in the graph that the boost flattens out around 7.6 psi and drops off from there as the VDC is trying to correct the wheel spin. That MUST be it!

I feel like an idiot.........

That has got to be what is going on. It is cool that the rear tires are breaking loose in third gear at that speed!

I'll try again tomorrow.

Lol, you know the ecutek functions are disabled when the vdc is on!

Actually, no, this is the first time I have heard of this. What functions are you talking about?

Yeah, when the factory traction control is enabled it takes over and therefore the ecutek tc, flat foot shifting and launch control does not work. When I forget to turn the vdc off and launch the car hard or accelerate hard the car will just bog and is non responsive.

So, Sunday after doing the log run and seeing that I still was not reaching my boost level, I decided to wash the Z and have a couple of cold ones. While washing the drivers side rear wheel a saw several spots of black on my wheel. When I rubbed it it smeared like grease. Well it was grease! I looked in the wheel and saw a ring of grease on the inside of the wheel. I crawled under the car (barely) and looked at the backside of the rear hub and there was the problem. The CV joint boot had failed and it was slinging grease out. The rubber looks good but something is wrong.

I decided to drive the car to work this morning and left the stereo off so I could listen for any strange sounds and sure enough, as you slow down coming to a stop you can hear a click, click, click coming from that area.

A new rear axle half shaft has been ordered and should be here Thursday. Looks like I have my Saturday planned now......

Have you rotated the supercharger correctly and placed the 45* coupler on?

No, I have not. I don't see anyway of rotating the volute without removing or at least un-bolting the SC. I can get to a couple of the socket head screws but not all of them. I just don't have the time to unbolt the SC at this point. My 90 degree coupler seems to be working fine and now that I know that I need to turn off the VDC during my log run and the boost should be in the mid 8 psi.

When the car was on the dyno at Z1, it made 8.4 psi and produced around 400whp. The temperature that day was over 100° so that probably didn't help the hp number and I'm still only on my third tune from Seb so it isn't dialed in fully yet.

Because I have been trying to do test with the VDC on, the VDC has been closing the throttle down due to the traction control system being triggered. At least that is my latest theory........ I went back and looked at all of my run data and each run EXCEPT the Z1 dyno run has had the same results. They must have turned the VDC off to get the boost number they got.

The new halfshaft is going to be delivered today and I will get it put on Saturday and then I can resume testing. I wonder, has anyone else had problems with halfshafts?

I'll shoot some pictures of what I find when I get there.

TBatt · 08-26-2016, 09:53 AM

Seb sent me an email asking about what was going on so I filled him in on all of the things that I have been working on with the car. Great guy to work with!

This morning I had another email from him with another tune to try. This one with two maps, the second one with more timing to try and get the power up. And a friendly reminder to TURN THE VDC OFF.

The new halfshaft arrived yesterday and it will go on the car Saturday. I should have the car ready to drive by the time the rain starts..........

TBatt · 08-27-2016, 01:34 PM

Got the Z up in the air and found the axle problem, something cut the outer CV joint boot. It was a very small cut but enough to sling a lot of grease out! What a mess!

Got the axle out and compared it to the new one and the new one has a problem. I think that it got over extended during shipping and the outer CV joint came apart. The boot is extended by at least and inch compared to the old one and the axle is longer by an inch. The bellows of the boot of the new one are spread way apart compared to the original one. The Nissan shop manual warns you to not over extend the CV joints or they could be damaged. The box that the new one came it was not very tight length wise and the threaded end of the shaft was well secured but the big end wasn't.

I'll take the shaft over to the dealer and see if they can just replace the boot and repack the grease. The OEM shaft is $560 from Courtesy Nissan, the one that I got was from RockAuto and it was $78 including shipping. $78 is the cost of the two CV boots for the shaft from Nissan.

I found the Gates Racing belt I was looking for.

Gates Racing K081088 8-Rib Micro-V and V-Ribbed Belts | Autoplicity

This is an 8 rib belt that will need to be modified by cutting off one rib for the new serpentine drive.

It's blue so it will look much nicer than the green belt that is currently on my car.

I dropped off the rear axle at the local Nissan dealer so they could replace the torn CV boot and repack with grease. They said it would be done this afternoon so I might have the car back together this evening.

The other thing I want to do is to find a source (other than the dealer) for some replacement screws for the front pan. Some of those screws are getting quite worn. These are the screws that have the integrated washer, 10mm head with a cross drive (phillips head), 6mm x 1mm thread about 15-20mm long. If I find a source I'll post the link.

I've ordered some of these to see if they are what I'm looking for. https://www.belmetric.com/body-bolts...thm94fev9lv990
