And I am very happy with the Bridgestone RE-01R's. Superb track tire that is very usable on the street.

Tirerack is a good reference point to beat your local shop over the head with and get a good price.

Joost

thank you.

do u have the same tranny as a 911 turbo?

My 2000 996 C2 has the Getrag G9600 tranny. I am pretty sure the turbo has a more heavy duty unit.

I have been running the red line shockproof for about a month now, incl. 2 trackdays and things are holding up just fine.

Joost

There was another thread on this very subject...I posted a dealership in the town of Ceres in Northern California who had the Mobil synthetic Delvac 75-90 for about $26 a gallon. The also told me they could get the Mobil synthetic in the hard to get 5W 50. Unfortunately I didn't find that out until after I paid $46 a gallon plus shipping to a company back east.....and Ceres in only about a half hour down the freeway for me.....CAVEAT EMPTOR.

I am not a Latin scholar, but it seems to me that CAVEAT EMPTOR ("Let the buyer beware") refers to the fitness of use of the product purchased and not so much the fact that you may have overpaid...

Just a thought.

I have read this post about the possibility to retrofit TPMS to a Cayenne with interest.

Looking at page 189 of the USA Cayenne parts catalog, I see a bunch of parts that seem to go on the rim. What about the grey box that is mentioned earlier in this post?

On page 524 there is mention of RDK / TPMS control units. One using 433 MHz and one 315 MHz frequency, but no part numbers.

The interesting part is that the OBC on my 04 Cayenne S already has an option to set psi or bar for the TPMS. I really believe this CAN be done. BUT HOW?

Any suggestions are welcome.

I'd be interested to find out which shop did the work resurfacing your DMF, in case I need to put mine back some time in the future.'

Joost

In 100 F Houston weather, stop & go traffic with AC blowing full, I have seen 110 C on the coolant temp (C6). From the previous post I understand that should be a problem.

Can anyone chime in here?

Joost

Assuming it was not sitting completely level, ie. front higher then rear and about half a quart extra had been added, given the internals of the tranny, would you expect any negative effects?

Joost

Loren,

I read somewhere else that the transmission should be filled upto 11 mm below the bottom of the filler plug.

I guess my question is, what negative effect can be expected from overfilling the transmission?

Joost

This is what I found on rennlist:

http://forums.rennlist.com/rennforums/show...amp;postcount=2

It does not use the OBC but the AC display. Lots of very useful stuff!

I found though that on my 2000 996 C2, the sequence to shift between F and C is "recirc" and "temp+" (not both "temp+" and "temp-" together).

Joost

I have the switch. Does anyone know the sequence?

Rgds, Joost

Interesting...

You mention that you keep an eye on operating temp with the OBD hack. I have the hack working and can toggle (with the switch on the dash, not the 4th stalk) from outside temp, to miles till empty, to AVG MPG and to something else (>MPH, ever wondered what that's for?).

Never have I seen the operating temp in that cycle. Looking forward to do this.

I had mine resurfaced about a month ago together with a clutch/pressureplate R+R and it ended up out of balance, resulting in severe shaking above 3.5-4K rpm. I replaced it with a lightweight flywheel. Very happy now.

I guess it very much depends on the capabilities of the machine shop that's doing the work. Assuming labor on pulling the transmission again if it turns out the DMF is out of balance, is more than the cost of a new flywheel (especially a good LFWF like AASCO's for $800 bucks), I would not take my chances when faced with the question again.

Joost

Due to increased gear clatter after upgrading to a lightweight flywheel I am now running the Redline Shockproof gear oil. It's not cheap but the results are amazing.

Initially I filled up (about 3qt.) with the super lightweight shockproof, but still had some clatter going on below 3000 rpms under high load (accelarating). I changed out one qt. of the superlightweight with the heavy shockproof and all clatter is gone now.

See http://www.redlineoil.com/products_gearlub...ubCategoryID=16

I guess in hindsight, using the lightweight instead of a combination of superleightweight + some heavy grade would have been the right way to go from the start.

Even if you are not experiencing gear clatter, I guess any car that sees severe duty use (ie. track time) would benefit from this product.

I am curious as to other people's experience with this product. Loren?

Joost

I am running the K&N stock filter replacements without any problems on my Cayenne S. Just do not over-oil. If any oil may have landed on your Mass Airflow Sensor (the flow meter you referred to), just take them out and clean with a spray can of MAF cleaner. Easy DIY!

regards, Joost

Loren,

If I am correct, the 996 C2 cans are compatible with the later 996 (3.6L) cans. How does that work out for 3.4L cans?

regards, Joost

I have a chance to buy 997 mufflers, but doubt if they will fit my 2000 996 C2.

Can anybody confirm?

Thanks, Joost

I bought my Pentosin 11S at the local BMW shop a while ago. Not cheap, but better than screwing up the hydraulics I guess.

Joost

[Thomas,

You lucky man! 2-4 times on the track per month is certainly a treat.

I have a 2000 996 C2 and recently installed the AASCO LWFW. I still had the very new unsprung clutch which is fine if you don't mind the gear clatter / low rpm grinding (which I believe is harmless, but we'll see in the next 10K miles or so), but next time I'd go for the Sachs sprung clutch. Maybe something more heavy duty, but with a LWFW you certainly want something sprung. You will always have some clatter and the Redline Lightweight Shockproof (2.5 qt. for the tranny) does a good job at reducing the clatter.

Horsepowerfreaks.com has a good deal on the AASCO and I guess Sunset is the place to go for the Sach clutch kit. You probably also want to replace the pressure plate and throw out bearing at this time with something compatible to the clutch set-up you choose.

Let me know what you decide on putting in.

Joost

HI,

Without warranting anything, I have seen people using Goo-Gone to remove tire grime (splats of rubber) after track events, indicating that it is not abrasive nor damaging to the paint. You might want to rewax though.

Joost

My wife's 04 Cayenne is having a problem with the Park Assist. With the shifter in D at standstill, the right hand side of the front display (with the green and red bars indicating something is in the way) goes crazy, even when there is nothing near the sensors upfront.

Porsche of North Houston already replaced the Park Assist control unit, but the problem persists and the service manager is at a loss as to what is causing this.

Another electrical gremlin?

Joost

Hi there,

Not wanting to ruin your day here, but the remark "residual leak" is BS.

Take a look at this DIY on RMS repair and judge for yourself; once the tranny is out, any decent tech should clean-up the mess left behind by leaking oil, clutch dust and other dirt.

http://www.c-speedracing.com/howto/996rms/rms1.php

Have they removed the tranny, clutch and flywheel and inspected the seal again, in order to be so sure it is not leaking?

Joost

I am running Redline Superlight Shockproof in my 2000 996 C2 tranny. Cold and hot shifting is very smooth and I like the high-tech features of this oil.

http://www.redlineoil.com/products_gearlub...ubCategoryID=16 (no affiliation here).

It runs around 12 bucks a quart and for the C2 tranny you need approx. 3 qts.

Joost

A quick update here.

As I am running the stock unsprung clutch disk on a single mass (light weight) flywheel) I was getting a lot of gear clatter (pulses from the crank shaft transfer thru to the gear box). I don't mind a bit of noise at neutral idle, but all the way up to 3-3,500 rpms the clatter was driving me nuts. Transmission sounded like a coffee grinder, especially at low rpm / high torque! I am convinced that the noise is not damaging the tranny, but nonetheless went looking for a solution.

I got rid of about 80% of the clatter by replacing the tranny oil with Redline Superlight Shockproof gear oil. Great stuff! I figure I might even get rid of another 10-15% of the clatter by using the slightly heavier Redline Light Shockproof gear oil.

Joost

I am looking at the PET catalogue for the Cayenne (https://techinfo.porsche.com/techinfo/pdf/en-us/catalogues/9PA_USA_KATALOG.pdf), illustration 809-05, and it seems to me that you can only buy the dashboard in parts, not as a whole unit.

Hope this helps.

Rgds, Joost

Loren,

Any specific hoses that need to be removed for a complete drain?

Thanks, Joost
