what is an 'early' 3.4 996?

Question is if not LM’s then what? It’s a road car so not E88’s, it’s water cooled so no Fuchs, what does that leave?

Are BBS out, or do others have stock? CH and CH-R worth a look?

They've stopped making the outlaw wheels

I saw a wheeler dealer episode a few years back. They were tarting up something - cant remember what. Possibly a hot rod type thing. Anyway they had some wheels custom made by Image wheels [in Birmingham I think]. These were cut from a solid block of alloy. They didn't sound too scary price wise.

Fifteen 52's...

Lovely wheel on a 964 or older car... not seen any on a 996.

Can't get 18" in CH... 19's only.

I want to channel the inner Porsche 989 and put the 996 on Cup IIs.

They look terrible!

Fuchs with silver petals look great on a silver 996... some of the replicas have a nicer petal shape than the genuine ones, but I've only seen them with black centers.

Damn, didn't realise. Their website has disappeared.

[nunpuncher]

They were bought over. Not sure of the full story but it seems like a classic case of buying a business they understand but just not getting the brand at all. I think it's a larger company that does mass produced wheels. They've ditched the Magnus Walker tie in and the Ken Block tie in and supposedly won't be making to order.

I'm with this guy. Only I'd have used the word crap instead of terrible.

I've got no experience of machining wheels but I do design and order a lot of low volume CNC bits and I would expect a custom machined wheel to cost a bloody fortune! Maybe (maybe!) a two or three piece design would be cheapish (~1k per wheel) but I can't see a one piece part being 'not too scary' but maybe that because I'm not a Company Director?

They made have been split rim - can't remember. An enquiry to Image wheels wont cost anything.

It's all go in the world of early 996 ownership. My driver's window decided to stop working at the weekend, so I had to regulator mechanism thing replaced and that's all fine now.

However, sitting in traffic just now I noticed things were getting a bit warm so I did the air con display thing and the coolant was at 99/100. I did the classic 'heater on full' trick and it slowly got down to a more comfortable 92/93 (as I got hotter...). When I parked up at home I stuck my head down the front of the bumper and could hear both fans going, perhaps the passenger side one not as fast but I think that resistor needs replacing anyway; the seller gave me a spare and said he hadn't got round to fitting it.

But! I also noticed that the engine bay fan wasn't moving. Am I right in saying this is supposed to be on permanently?

[Speedgelb]

tomtom, nothing wrong with it sitting at ~100*C in traffic. The fans will intervene at low speed when it reaches 104*C.

You can test if the resistors are working by turning the AC on, with the engine below operating temp. Both fans should spin (on low) - if one doesn't, then the resistor may be goosed. Could also be the relay, or something else, but it's usually the resistor.

Engine compartment fan only comes on when the engine bay temperature exceeds a certain threshold. Can also come on when parked up, after being driven enthusiastically.

Alright so why is mine so low then?

I had a few emails with another member here and it looked like the figures on his CoC were messed up - the 187 for NOx was actually the HC + NOx value. If you add up your HC and my NOx value (0.035g/km) I bet they come to 187? My HC value is 0.152g/km.

That was me!

In discussions with Porsche GB at the minute. They've been in touch with the factory and have asked for a bit more info (that I can't give them right now as I'm away on holiday for the next couple of weeks) but they think the paperwork might not be right and agreed something weird is going on with the numbers. Keep your fingers crossed. I'll update the thread with more info when I can....

Just to update everyone on this - Porsche GB agreed the initial data they sent me was wrong and sent through some new paperwork from Germany.

Sent that on to TFL pointing out that the NOx levels were on par with the Euro 4 spec a couple of days ago and I just got the nod back that it's now exempt. Result! Means I don't have to think about selling her on just yet.

Basically I think every 3.4 996 is likely compliant as long as you can get the right paperwork from Porsche

Thanks to tomtom and shalmaneser for being super helpful at getting to the bottom of this.

There seems to be quite a range of operating temperature. I haven't done a proper drive out of London with the temp display on the climate unit but as a guess from the gauge I'd say it sits around 80-85°C when driving around in open air, so that's in the region of a 20°C variance. I think the only other car I've driven recently with an analogue (and un-damped...) gauge is the 355, and that has a ~10°C range depending on thermostat...

I've also noticed the car takes a long time to get up to temperature if driven on the open road, eg it'll sit below the '8' of the '80' on the gauge until I've sat for a bit, at which point it establishes a new temperature floor around the middle of the gauge.

With all that in mind, I suspect a potentially dodgy (stuck open) thermostat

[nunpuncher]

Hopefully Porsche are efficient enough to stick a post-it note on the file to correct their calculations for any future applicants.

Wonder if a 3.4 C4 would pass. Not that it concerns me as I've not been near London in years and haven't been near a city of any description for 6 months.

Mallone seems to have had a much simpler application process than I did, so perhaps they've taken on board my data for future applicants. Fingers crossed that's the case.

I believe any 3.4 car is compliant, assuming you get the correct paperwork from Porsche.

They've done the same for me - had to send back my initial bit of paper, now just waiting for the replacement and hopefully the good news!

I find in traffic the temp needle points straight up which is about 100 degrees. See my temp log here:



but when moving it'll drop back to the '80' mark which in reality is about 90 degrees as can be seen above.

[HughG]

Yep my needle moves from the middle of the 0 to just right if the 0 (or 80) which represents 90-100degrees.

This was my pre-radiator change graph, just before the Blackwall tunnel back to near Tonbridge.


Now the rads are done, I’ll repeat on Friday when I next have a run to do.

Edited by HughG on Wednesday 26th August 20:38

[tomtom]

Hmm. I'll have to try to do something similar I think as I'm always paranoid about coolant temperature.

Are you logging that using a bluetooth OBD II reader and some app..?

[HughG]

WiFi OBD reader and “car scanner” for me.

I would prefer to be able to see the raw data but haven’t looked at alternatives yet.
