Building a 400bhp+ 2.5 ltr 944 Turbo
- Thread starter PSH
- Start date
Got my 996 under a car port, last couple of winters it got covered in dust and other crap so this winter I invested in an ultimate outdoor cover from Classic Additions (10% off with PCGB code). Gives it that extra protection under the carport. Have took it off a couple of times whilst moving the car around and the car has stayed lovely and dry and as clean as when it was first covered. No marks from the cover (it has a nice soft inside lining). Just make sure your car is extremely clean (and preferably waxed) before covering.

That's the plan...thinking of 3/4 depth to allow plenty of circulation underneath. Thanks for comments on colour....i would like to get it buffed one more time before ceramic coating....not untirely sure as the actual finish is superb...the guy did a great job wet sanding her by hand.

Stunning Pete! Mine is going in for a full front end paint later this month, it will never look like that but hoping to get a bit closer!
Wings, bonnet, bumper and one sill getting done. Sills were done 2 years ago but something has hit one of them and damaged it
. Wings needing attention at lower edges and front bubbling a bit, new metal getting put in, bumper has cracked paint and bonnet getting done so it looks same. Will definitely be a big improvement.

I'm sure yours will look just as good...i had a new passengers sill this time using patten parts which are just as good as original. Some years back I used the same make patten parts to repair the lower wings too. You are probably already aware of the company but if not, check out classiccarpanels. My bumper also needed repair, this was from hitting a metal strap from a curtain sided truck at speed, they did a great job putting the bumper back to shape. Also the bottom of the bumper was badly scored from hitting kerbs, all fixed, I'm kerp my distance from kerbstones now...
I still think it needs more buffing but worried about putting swirl marks in the paint so might get it professionally buffed and ceramic coated, if only I had the cash spare...

Sorry, I missed this reply....a cover may be an option at some point but I'm very wary of covers from a past bad experience of them damaging the paint. I do have a new cover that could be used, it has a soft interior but is it soft enough?. The problem with covers is strong winds, they rub the paint especially on the roof which causes more than just marks, it lets moisture molecules into the paint, something I learnt the hard way. Having said that perhaps tarp around the carport might reduce the wind making use of a cover possible, I'd still want a very soft inner cover below it. The added issue that I have is living on top of one of the highest points in bedfordshire, it gets bloody windy up here.....

Good day all, I posted this on FB earlier but will post it here too as it's part of my car's story...
Well, I'm a happy bunny today, some may recall that I thought the gloss needed a little buffing, I now understand and know just how good a paint job this car now really has. I owe a big thanks to my son Peter for sending his friend Tarik over yesterday to give the car a proper professional wash plus checking the paint for any blemisses/swirl marks and also check the paint depth for any future buffing to acheive perfection before ceramic coating. Tarik is clearly a top class valet who believes in having a perfect paint finish rather than using products that mask swirls with fillers etc. Tarik spent a good part of the day washing the car and I have to say he really made her pop. You are seeing just a plain wash here, no polish applied so in effect just the virgin paint finish. Tarik also taught me how to wash a car properly and using a light, showed me the few swirl marks from my waxing a few weeks back, amazing how quickly these things appear..
Tarik's advice is to give it another 2 months for the paint to fully harden and then look at a two stage polish followed by a professional coat of ceramic, my thanks to Tarik for his time and shared expertise in helping me get the best look from my car.
Pete
Further to what I posted on FB, Trik did pay close attention to the overall finish, it was clear to him that the car had been entirely wet sanded, a process that takes many hours, the result is evident by how the reflections in the paint look. A good example is seen in the last photo, look at the spoiler reflection, the lines are perfectly straight showing how flat the finish is, this goes for the rest of the bodywork...each panel is flat, not a ripple in sight.......

So shiny! My car went to the paint shop today for rust removal and cosmetic surgery. I can't wait to get it back and to look almost as good as yours. The guy I'm using comes well recommended and as a bonus has lent me his mint 1999 Renault Laguna RTI to use while he has mine. Have to say its a lovely car to drive, never thought I'd say that about a French car............

Hi all
As posted elsewhere I've had some clutch slippage of late, actually the clutch has slipped in the past 6-7 years a couple of times but soon settled after backing off and going for it again. However, when driving to the car meet last week with my neighbour on board it slipped much more, the extra weight was clearly asking to much and now it will slip with only me onboard. I will state that its fine for normal driving when using little boost but clearly needs upgrading. Currently I have a sachs performance clutch fitted but using the larger 911 turbo (930) friction disc. So my search began on what to fit next, most out there when you look are limited in how much torque they can hold, that is until you start fitting paddle friction disks but they take away the OEM feel of the peddle, I have driven a paddle clutch and didn't like it.
I search the forums and looked at the various manufacture offerings and noticed some old posts (early 2000's) singing the praises of the Centreforce dual disk setup. As an amature engineer this patented design intriged me with its dual disc and clamping weights wich give a claimed clamoing force of +90% to a normal clutch plate. One problem though, this clutch is no longer in production for the 944, on asking the question 'why' I was informed due to lack of sales, at the time it was much more expensive than other makes. Further enquiries where made and then I hit gold, Patrick Motorsports (reportedly highly thought of in the states) had one new/old in stock, this is complete and untouched in sealed box, that will do me. I placed the order last night, received shipping details soon after and paid the import duties this morning, parcel will arrive Tuesday 30th.
Not sure when it will be fitted but I'll report back once done.

Good luck, it does look a bit paddley, if that is even a word! Be interested in how it feels.
I went for a cup disc for mine from the states with a standard pressure plate. It feels great but admittedly I'm only putting just over 300 horses through it.
Can't remember what Eldavo runs on his, but his set-up must be dealing with the thick end of 500 horses.

According to what I've read the peddle feel is either the same as OE or even lighter due to the dual disc design. Without having it in my hands I won't understand fully how that part works, seems interesting. I can understand the 90% increase in clamping force as it describes balance weights which increase the clamping force as revs increase, same principle as a centrifugal machine.
I'll post pictures when it arrives..

My 944 turbo puts down 530 lbs.ft and my KEP stage 2 pressure plate has no issue holding all of it with a 930/2 disc. I have never understood the appeal of multi disc set and/or paddle clutches for road use but happy to hear of your findings when yours is installed.

That is pretty damn good Pete! I've ordered a few things from the US recently and all have arrived within 3 days or so, and I only got stung by HMRC once.
Your post about the clutch got me doing some research and I noted that many rennlist folks were using the Cup clutch up to and around 400hp (I believe, but cannot 100% confirm that this is now the only clutch plate / disc supplied by Sachs, my new kit appears to be this one, it has 4 large springs and none of the helper springs that the older standard one did), and a stronger modified pressure plate (e.g. KEP 1/2) or the Cup pressure plate (according to the Sachs online catalog, this is no longer available). I wonder if the pressure plate supplied in the newer kits is the same or similar to the cup pressure plate.

Even better considering this was over the weekend, DHL stated 2-3 business days, which usually excludes weekends. HMRC stung me for £196 but I was expecting something like that, total cost including import and postage was around £1230 which interestingly is about the same as the Helix.
I'm not sure what the cup clutch is these days, the version with the smaller springs was replaced many years ago, and the one already in the car now has the 4 large springs only.
I did check out Helix via Torque Developments who also supply Centerforce here in the UK, they enquired on my behalf what Helix can hold, their Paddle disk holds a max of 376ftlbs which isn't enough. When the car was dyno'd at the lower 368bhp she produced 382ftlb which ok, was at the flywheel but our cars don't lose that much through the torque tube in comparison to other types. The Centerforce is also claimed to have lighter peddle pressure due to its ball bearing design, would you believe their top race clutch is claimed to hold 1300ftlb,, I bet that's a bit stiffer on the foot...
I show here he reverse side of the dual-clutch disk.
