Hi Guys,

I swapped my clutch this Weekend.

Went from a Hard Core 935 4-puck clutch disc (sachs) with a Sachs 935 pressure plate. It was Exactly as the clutch Brian discribes.

I swapped to a KEP Stage 2 PP with a Street Race Organic Disc (SRO) as KEP call it. They shipped a complete kit. Very well packed.

I just Love this Clutch! Very smooth and nice and by spec it handles loads of power! A little more effort to depress the clutch pedal, but it's very nice

Brain: Get that clutch disc swapped to a normal style and not the "puck style". I'd imagine that my 4 puck is even worse compared to yours... Only way to get a more or less smooth take off is to engage at approx 2500rpm and slip away.

Cheers

I've put about 100 miles on the Hulk clutch and it has calmed down quite a bit. The chatter is nearly gone and the effort to depress the peddle seems less (or I am just getting used to it). No time to yank the engine again so I'll have to live with it a while.
Good news is we now have a bone dry engine!
This thing was leaking like a seive from everywhere. Resealed a lot of stuff.
This is a shot you wouldn't like to see:




Some @$%^&* stripped out the oil line inlet fitting at some point and just left it that way. Probably been leaking for years. Fortunately I had a spare oil pump assembly.

I wanted to change out the factory steering wheel to something more in line with the theme of the car. My spare no expense wish wheel would be an all gray 930S. I can't swallow $500 for one of those so found this Momo on eBay.
Problem now is it does not fit. I puchased what I thought was the correct hub and it won't fit either.
Does anyone know what Porsche this thing went on that won't fit 911/930?
Is there any way I can use this wheel?

Here is the ill-fitment wheel/hub:




Here is the good fitting wheel hub combo; problem is the hub is for a VW!




Here you can see the difference in the hubs:

Got and adapter for the Nardi hub, have not put the wheel on yet.

Finally got my gages in the radio hole today. Now maybe I can see what's going on a little easier. Waiting on my Innovate AFR meter to come back; it never worked right and is being replaced under warranty. With system pressure, control pressure, AFR and Volts I think I have about everything covered for troubleshooting the fuel system!

Love that boost gauge...and those rear tires look like steam rollers, they are so wide!

That boost gage is an awesome tool. You can monitor vac and boost which helps tune and allows you to adjust your highway driving for max fuel mileage.

Can't wait to use the dash mount fuel control pressure gage in conjunction with the AFR meter. Ultimately I would like to log system pressure, control pressure, boost/vac, AFR, and Voltage. That should really help me fine tune the fuel system when testing the various exhaust components. If the fueing does not stay consistant it throws off your horsepower numbers. I truely believe some of the gains companies claim are from running lean and overboosting rather than from a better designed exhaust product.

In the middle is a rectangular Andial intercooler in/out/differential temp gage. I just recieved the Gen III version of my intercooler and cannot wait to test it this summer.

Yes those tires/wheels are monsters! I want to find a metal guy that can add 1" to my fender flares but I have not found such a craftsman in my area yet. The tires pucker on the rims which need to be an inch wider (they are 12's).

C'mon Brian, if want find an area to improve your gas mileage, just take a look at those steam rollers at the rear of the car.

Moved the gages around a bit and all are now functioning. Fianlly now have this dude dialed in! The fuel system was all out of wack from a lazy alternator due to a faulty diode. The PO's mechanic had futzed with the mixture screw to compensate. Now I can see the voltage, AFR, control pressure and boost/vacuum. Dialing in the fuel curve increased the vacuum a couple points. Really cool to watch the fuel pressure rise during warm up and the corresponding AFR. Even more cool to see the pressure drop on boost. I'll do my best to get some film of this if I can figure out how, the GoPro sux inside the car. This bad boy ROCKS now! The 345's may not live too long, ha!

I have got the same transducer along with an analog gauge. Guess where I copied that from...?

I actually have a datalog form the other morning on the way to work. I can not figure out how to upload it.
You are absolutely right, it is super fun to watch how the pressure changes, makes you Understand CIS better. I also realized my car needs leaning out. I didn't realize because my XD-16 gauge has gone bazonka, so I have to use a laptop

Anyways, Brian your car looks supercool in "hindsight"

Congrats on having it sorted.

Brian, how did you determine the fuel system was being affected by the alternator (did you check voltage at different RPMs with a multimeter or something)? If so, what voltage numbers were you seeing?

The car was plagued with poor performance and a rich condition from the get-go. Many things were wrong and I replaced just about everything in the ignition and fuel systems. Nothing had been maintained so every new part helped but nothing cured.
I first noticed the voltage issue when I plugged up the remote AFR meter that I use to tune with. It plugs into the cirgarette lighter and only read 10.5V with the engine running. I thought maybe there was a problem with the lighter socket and continued on to other things. Shortly after that I was tuning another 930 and noted 13+V when running so I stuck the sensor in my tailpipe and got the same pig rich reading as before. Our mechanic is an electrical wiz so I had him take a look at the alternator. He found the problem in like 30 seconds. There is a brown wire diode behid the tach that feeds the alternator light. That diode had burned out so the alternator light never came on. Gotta love working on old cars ...

Thanks for the info, Brian. So it looks like you've got your Innovate meter back? Is it working well?

Yes, so far so good. They sent me a new one and didn't say what was wrong with the original.
Fianlly I feel confident driving the car outside of city limits. We'll start making wider circles and shaking down other systems until I can drive it across country if I want to. This is a cool car and it must get out of the garage a lot more than the red rocket. Life's too short.

that diode problem I had the same thing for about a year. took forever to find it then it took me another year and a half to find a new diode.

Biran,

tell me about the sensor & adapter on the WUR.. assume this is for the new fuel press gauge?

Thx

Yes the new fuel pressure sensor came with the gage. The adapter block is the same type used on all my other cobbled up devices. WUR fitting is 10M and very close to 1/8NPT but not exact. For permanant instals like this one an adapter is recommended to do it right. Don'twant to mess around with fuel leaks.

Intercooler gauge

Love the intercooler gauge. What are the intake and corresponding outlet temperatures reading under full boost? Is that a Davcon?

Thanks for the info Brian,

I may just have to add one of those since I'm still futzn around with my center console. What brand gauge did you go with?

Thx

Fuel pressure gage is Autometer, works great!
Andial intercooler gage is for testing purpose. We are working on a thicker original replacement unit. The current one is about an inch thicker and uses the OEM shroud, the new one goes all the way to the deck lid grill like the old B&B and Garretson short necks did.
