what is an 'early' 3.4 996?

[Fast Bug]

I've done Bedford in mine. After a few laps it showed some areas that needed improvement in the braking department, so went for braided hoses and changed the discs and pads.

Standard rubber will be fine, I don't think they need more grip if I'm honest

[BillyB]

There was a chap in a 996.1 at Thruxton 2 weeks ago that he said was standard apart from pads and suspension. It was going very, very well indeed.

Of course it might have blown up on the way home for all I know...

[Dammit]

Would anyone have a boot-lid going spare after (for example) fitting a ducktail? I have some rust in the seam of mine which means that it needs replacing.

When I had tuition from Markus "TheGoose" at Oulton in my 996 turbo, he took me out in his boggo 996 3.4 and drove the doorhandles off it - completely stock, knackered tyres etc - it was fantastic

No reason a standard car won't be good fun on a trackday

Are window regulators easy to fit?

[nebpor]

Its definitely DIY capable but I've always had mine done, as you need to make sure you've sealed the doorskin properly, or the car will leak water into the footwells under the door!!

Plenty of videos on youtube - the only thing to be careful of is that the regulator is shared with the Boxster/Cayman and there is a particular notch on the regulator that is set so the window goes up/down to the right position

Yes

I did 2 - or 1 twice. First one was a cheapo part and only last 9 months. So I did it again.

My new 996 leaks a bit which has window regulators untouched by Me. So clearly someone else got them slightly out or they are always susceptible to being slightly off.

My advice is once you have it fitted then leave the membrane and or interior door panel off the car for a bit so you can easily make any adjustments should you feel the need. Then once you're happy you can refit everything. I noticed some extra wind noise so did some tweaking.

Some of the Youtube experts recommend putting masking tape on the glass where it goes into the regulator so you know where to refit. I found this a bit useless as the brackets on the different regulators were different. Possibly because I was changing to a cheapo and then back to OEM. Once you figure out what you're doing it is relatively easy to tweak or adjust. Although I'm not certain you can ever get it perfect again once it has ben apart.

There is a Porsche doc which explains in detail how to adjust these. I found that harder to understand than a - insert joke here about a Rocket Scientist speaking Dutch at a Jazz Festival.

Pics from my 996 thread --- added the last one to show what happens when it needs some more adjustment, this was a few weeks or months after fitting and I had decided to visit a car wash

[nebpor]

Nice one ATM!

[Fast Bug]

Ta, I think my passenger one is on its way out by the sounds its making

[Slippydiff]

Not sure if the door is fully shut in this image, but if it is, the adjustment is way out, as the back edge of the drop glass should be parallel with the adjacent body seal.

How many people are tracking their 996s? Any issues if being run on standard rubber?

Yep no problems on Goodyear eagle f1 assy 5. Even with standard geo, running m030 with h&r rear anti roll bar I was wilting before the tyres. Yellowstuff pads with otherwise standard but good condition brakes worked very well indeed too.

Thanks all re. the track advice - I know these engines aren't the strongest but I presume if not using sticky rubber then a baffled sump isn't really needed.

Will get mine out on a trackday at some point

[PGNSagaris]

I would 100% get a baffled/deep sump if doing regular Trackdays.

Even with one I managed to grenade a 3.4 engine at SPA. Oil starvation.

Very expensive outcome.

In translation; our “integrated dry sump engine is a marketing trick, it is actually an open deck wet sump. If you track it you will kill the engine due to our crappy engineering ”

My old C2 had oil surge at Bedford (road tyres, X51/FVD sump fitted)

[Dammit]

I've just been doing some reading about the Corvette LS7 semi-dry sump system, it's a different take on the idea to the one which Porsche had for the M9X engines. GM went for an external tank, with separate pressure and scavenge pumps - albeit those were two gerotors in a single housing.

It's an interesting though exercise to consider how you'd move the "tank" from inside the M9X to an external location, with the benefit of putting the pressure stage pumps intake at the bottom of a column of oil.

I've done Bedford a few times including with my C2 and would have said it would be a struggle to get surge there. There aren't any long sweeping bends to speak of - I think it's long left handers the 996 especially struggles with? As far as tracks go I'd say it would be pretty safe for oil surge issues, certainly I've not seen any. Your driving is probably better than mine!

It is a fast circuit and the car does get worked hard there, my idle oil pressure was pretty low down the gauge by the end of a session in the summer but no sign of an oil light which I understand is a little less variable than the pressure gauge.

I would have thought an oil cooler solution would have been devised for the 996 but no sign of one I could see, other that using a spin on filter adaptor + sandwich block for a cooler which doesn't seem popular for some reason.

I did read there was some concern about pressure drop over the long routing from a front mounted oil cooler back to the motor but this doesn't seem to be considered a problem with older air cooled cars. With the uncertainty about the value of the X51 third front (coolant) rad I would have thought an oil cooler in that position would make sense.

Bit the bullet and bought this. I've been tinkering with my 996 for the last few months (new clutch, flywheel, RMS , AOS etc etc) and spent too much time searching for torque values online. Not a cheap manual, but nice to have a physical book for a change. It's hefty as well, could always make use as a door stop if required.

Now I need to buy that manual too!

My 996 is coming out of storage after 9 years at the end of this month.

one of the very first to come to the UK, zenith, no sunroof Carrera 2 manual with Savannah (which I am in the minority who love).

I drove it a couple of years back and did rads and coil packs then, so off it goes on a trailer to the best man in Stockton for all fluids, major service, MOT (plus an annoying issue with the steering wheel column not adjusting) and then back to me for May.

I plan to drive it just for pleasure occasionally.

Glad I kept it.

Will post photos when back from the workshop

I also like Savannah. Probably because my first Porsche had it. Looks poor on a 9x7 with the silvery grey detailing but on the 9x6 with black detailing it works so well. I think it is exterior colour dependant and I'd prefer it on Darker coloured cars. Dont remember seeing it on a Zenith car so ... we need some pics man.
