New member with a 1988 Lux

Hi all
I live in Sheffield and have owned my 1988 Lux for just over a year.
I bought it when my MK2 Golf GTi was written off and after a fruitless search to replace it with another Golf I decided on a change.
It's a nice original example having covered 63K miles from new with a good service history with most tax discs etc.
It was stood for 10 years so needed some re-commissioning when it was discovered in a late owner's garage.
This included new sills and painting the sides of the car, along with a full mechanical service inc. belts, tensioners etc.
The interior is in great condition and everything works including the digital clock.
In the boot is the sunroof bag, unused spare and compressor.
I haven't had to get my hands dirty really, mostly cleaning and replacing a few blown dash bulbs.
It took a while to get used to after the Golf but it has really grown on me. It's actually more economical and uses no oil nor leaks any.
The only issues I have had are the heater constantly blowing hot (I changed the control unit but no joy) and a slightly lumpy pick-up and lift-off, which I am having investigated on Thursday at John Noble Motorsport, along with a service before its hibernation.

I look forward to bringing the car to some events next year.

Waylander is talking about the constantly blowing hot problem.

The plastic clip is only a couple of quid, but the scuffed knuckles make it seem more expensive!
 
Thanks for the replies. I did check the cable clips first, after removing the glove box. The one nearest the dash was fine but the other had been repaired with a tie wrap so I replaced it. As it didn't fix the problem I replaced the Heater Control Unit but to no avail. Turning the temperature control knob didn't activate any flaps so I am wondering if the issue could be a vacuum supply to the heater flaps, assuming there is one.
 
Could be an open circuit thermistor, I believe that when they go pop the heater fail safe is go hot

i would start by finding a map of the vac lines and making sure they are all connected in the right places and the one way valves are the right way round
 
Car looks lovely! Kind of miss my Guard's red 944...

What do you mean by "slightly lumpy pick-up and lift-off". Does it kind of lurch forwards/backwards when you put your foot on/off the accelerator? If so, it could be the clutch. The original clutch will have had a rubber centre and this breaks down over time. Even if there is plenty of meat left on the clutch itself, the only course of action is to replace with a new (spring centred) one. Let's hope it's something else.

Thanks Briggy. Having never driven a 944 before mine I don't know how it should drive. The power delivery on pickup isn't linear, it's sort of a 'wave' and then smooths out. I have also noticed when going down hills on the overrun with my foot off the accelerator sometimes I can feel the car jerking very slightly, as if I had touched the throttle and then lifted off. I suspect a fuel or air/fuel mixture issue, perhaps a lazy AFM. It's going on a rolling road tomorrow so let's hope the garage can find out what's happening. The occasional clutch judder at low revs when setting off could be a sign it's getting ready for a replacement, but it's not slipping and is fine in traffic.

Regarding the heater always on hot I will check all the vac lines next and go from there. I recall reading somewhere that it's a good idea to let the car fully warm up before connecting the clips behind the glovebox otherwise a flap can be locked in the wrong position. A lot of the hot air seems to come from the 2 dash vents and I can't turn them off. A good excuse to remove the sunroof last summer!

Are the wheels correct for my car? I ask as I saw a low-mileage D reg 944 at a show and the wheels definitely had a deeper rim.


 
Car looks great to me &wheeloffset seems correct-I think Turbo's have larger offset rears but an expert should be along soon to advise you.
A good simple mod to improve throttle response is a round throttle cam instead of the eccentric standard one fitted-we have them on both our 924S's-Porscheshop et alia sell them around £20
 
Your car looks lovely, wheels are correct, hot air is a broken flap clip as discussed, remove the glovebox to get at it, or the non return vacuum valve ( black and blue jobbie) adjacent the bulkhead, a few quid from your main dealer.
My Turbo S power comes in a wave, a large one [:D]
 
Scam , one of the few educated ! The S2 lurkers would be whimpering when full boost hits if they were to be in the car, I would bet my house that the my 944 Turbo is quicker than my slightly modified 3.8 C2S to 3 figure speeds, on a private road of course :p

I would bet mine is faster than the majority of all Porsches... new, old or turbocharged......the driver, on the other hand, is most certainly not, I'm getting too old....:)

Pete
 
I would think so Pete. You must be nearing 400bhp by now? Plus you still need a remap if I remember correctly? What do you think is possible?

PS sorry for thread hijack

Stuart
 
yes, sorry for the hijack chaps... ahh.. now there's a question Stuart.. 400bhp is a very safe bet for now...yes she's still running on her 'running in' map...as for what's possible? To date she has recorded just over 1.5Bar of boost, so 22PSI. That's a lot of boost, but I'm confident that she could do more with a more aggressive ignition setting, there are two such settings on the other map which I haven't used yet. These engines can handle much, much more than they left the factory with, especially the early cars with forged internals, remember the 924 GTP (early 951 engine with 16v head) ran for 24 hrs non stop at Le Mans with well over 400bhp on tap. My own block is much stronger than Porsche's original, able to hold much higher boost levels and RPM, as proved a while back when I missed a gear, hitting well over 7k revs with no damage to the engine..

Pete
 
Awesome stuff Pete. Mine hits about 21psi floored in 5th backing off to 19/20. That is in the region of 320bhp and there ain't much on my private test road that can live with that. Adding in another 100 horses would be insane with the way a sorted 944T picks up from 60mph with the taps fully open. PDK or 4 wheel drive would be handy!

Stuart
 
Hi Stuart,

thats some pretty high boost your running also, just wondered what mods does yours have?

Ps sorry again for the hyjack of the thread
