1275kg surprised me, didn't think the doors, bonnet and wings would make that much difference, great news. That weight saving with the extra horse power must make this car really shift. Are you attending any of the DN dates next year I'd like to this car in the flesh one day?

Looking through the photos, what is that under the bonnet? Has your car had the cup electric steering fitted and therefore ditched the heavier hydraulic system and thus contributing to the weight saving?

Also note the front suspension struts look like they have had the 3 bolt hole elongated and been marked. So you can manually change camber on front wheels. Is this correct?

Great journey the owner went on, will be fun tweaking it but not a whole lot more to do! The four corners add up tp 1450kg which if a wet weight with driver ballast is pretty lean. My RS wet with ballast weighs 1560kg.

Hi Jon, I have asked the company who built the car to give me the specifics regarding the weight as I if it had some fuel in it at the time it may be lighter again also the front cage extension is quite a heavy lump so it may potentially be <1250kg.
The carpet set is -17.5Kg and the Akrapovic exhaust is another -17.5Kg. Steering wheel is lighter and as you say it has the CUP steering system, Carbon door cards... it seems when all tallied up it really does make a difference.
I only live about 40miles from the Ring so I'll have a look when the DN dates are.
I guess the index marks on the turrets are for previous geometry set-ups. TBH I haven't had the car very long and have so far been concentrating on the little bits and pieces that I picked up during my inspection. The car will now hibernate for the next few months so I will look into the aspects you mention when the better weather arrives.
Looking through some of the invoices it also has a different clutch with this pressure plate fitted. The gearbox has had a €7000 revision (again I'm not exactly sure what they did).

I have been speaking to Steve Rance on PH about various aspects of the car as he is interested it what development to undertake with his new 997.1GT3CS. One area he is still a little unsure about is how to approach the ABD/traction/braking systems. I took a few pictures today of my brake system and to me it looks like the main loom going to the ABS system looks a little exposed. Do you know if this is normal. Also it has 2x braided steel hoses going from the master cylinder to the ABS unit (again this could be normal and looks like it is designed this way to allow for flex/movement):



Yesterday I also had the rear wheels off to scope what was going on there. Here are the pictures:










The rear tyres are like something from tractor; can't believe how wide they are when you get them off

ELA, you paperwork says the car weighs 1275kg? But the corner weights add up to more at 1450kg ?

Every thing looks standard to me, including the exposed wiring loom to the ABS unit. The braided hoses are not standard, something has been change their. I'll post some photos tomorrow.

I asked Steve the same question and his response was and I quote:
"I wouldn't be too worried about the corner weighting. That's normal"

I have emailed Teichmann to ask how the car was configured at the time of weighing. The 1275kg is correct but I just want to know if this included fuel, front cage extension... Stock the cars are 1375kg so the weight quoted sounds about right to me.

Depends on wether it had fuel in it or driver ballast. I doubt they took the fuel out? And if it was corner weighted then they must have put some driver ballast in there or whats the point. Porsche quote curb weights i think so add 70kg driver and 50 litres of fuel at say 35kg, air con and any other options and 1375 is now over 1500 ish. 225kg reduction from there is quite a bit.

I was having a little look at the car today. I removed the airbox today to get a closer look at the engine. To me it seems that 1-2 ancillaries have been removed and thus may be contributing to the weight loss. From the pictures below does anyone know if this is the case?



I measured the throw between neutral position and then 3rd, which was 44mm (measured from the upper surface of the gear knob as per pic below. Does anyone know if this shorter than standard as it really a short throw (real rifle bolt action)?


Is this filter in the CUP/GenII airbox standard (a paper element with a foam outer layer).

[imghttps://farm5.staticflickr.com/4362/36845595750_6548050574_b.jpg[/img]

Throttle assembly measures around 90mm⌀? is this stock?



I have no idea why the first 2 and last 2 images have turned 90deg Question so my apologies for any neck injuries caused Very Happy

Air con compressor and steering pump are absent by the looks of it. Laughing Seems to , not certain, have standard engine mounts which is a bit odd considering the lengths gone to? TB diameter is 82mm standard, your ruler seems to be measuring the rubber connector rather than the inside diameter of the TB? , i think 97 cup car is 82mm also Shift throw looks standard.

Sorry Senoj, the camera angle doesn't show the throttle too well. It could quite possibly be 82mm though as I was measuring as per the photo but it certainly seemed more toward 90mm rather than 80.
Engine mounts are defo stock as I have the RSS ones fitted on my 996 so know what these look like Thumb
I also have a 997SSK on my 996 which is what made me question what is fitted to the RS as it seems really precise and short.
I guess the AC system as PAS system would weight a fair amount? (I really need to find out how the car was configured when it was last weighed at 1274.5kg).
Many thanks for your help Thumb

This is the PAS system now fitted. All I know is it from a CUP car. Which Cup car I have no idea Question

About time for an update:

I previously had to remove the front lip spoiler to get up the driveway but decided to re-landscape some of the entrance garden to make it a little more RS-friendly. So for the last month or so I have spent every waking hour on this project
Now finally had the chance to test if all my efforts had paid off.

Here is the starting point. All the trees on the RH side and about 1 meter of earth have to be dug out.


Collected a load of natural slate from the valley where I live to build a wall




My mate popped by to check progress




Luckily I had some help on-hand



voilà; stage 2 complete (stage 1 described elsewhere is in thread which was somewhat of a failure)


So this morning, being my birthday I couldn't think of a better time to remove the covers and do a little testing. Primarily this is what I'm up against; 65mm ground clearance vs. a rather steep incline.


Covers off and she's out for the first time this year Very Happy



Be rude not to give a little blip of the throttle (3000rpm left in reserve as it was a little early for the neighbours).

Open Youtube Page


Well truth be told I still have issues with an element of scraping but it is something that can be lived with and I no longer need to remove the bloody thing every 5 minutes.


The car even gets airbourne during this manoeuvre, about 5cm off the ground.

Undutched, Carfreitag sounds like a good idea. What are you having done on your 964?

Nick W, many thanks for the kind words Thumb

Getting some more power. Have some GT3 engine parts and a Turbo going on Very Happy (as in 4.0l Turbo). I hope it's ready by June/July to go for a few shake-down laps on the Ring and doesn't blow.

Will be there either with a GT86 and some suspension work or the 993. If I see your car, I'll try and have a quick chat! Haven't done a quick lap in over a year, as the 964 has gone overboard nooo

Your 4.0T project sounds absolutely mental; your not related to the late German Wings FO are you Very Happy
Good luck with the project and really hope I get to see it some day Thumb

Great car and a great thread. Picture heavy is always good Very Happy . I am particularly impressed with your understanding wife. Anyone that puts up with a husband removing coatings whilst said item is balanced on a white chair has to be a keeper.

Can you not put a few raised blocks part the way up the slope to lift the nose off the drive. I have no steep slope but got some aluminium ramps made up to allow for my dropped curb verses the camber of the road.

I look forward to seeing more posts in due course and hope to see you on the Nordschleife.

Pip

Undutched sorry I couldn't make it this weekend. I was there the weekend before and I was working all this weekend.
Sub 9 in any car is an achievement even more so when it sports Prius tyres Hand

Thanks Pip Thumb I wish the wife was as understanding as you assume Grin
The solution for driveway above kind of works (when viewed through the lenses of man-maths glasses). I get an element of scraping everytime but it is better than removing the splitter every drive. I plan on an Alpine tour this year with the car so there should be a few nice pictures soon Thumb
