supercharging a 964
Discussion
I've just bought a 964 celebration (turbo body), for my christmas present, and i'm considering fitting a supercharger to it. I was going to get 9m to fit for around £4500. I'd be interested to hear from any one with a s/c already fitted, primerily about the performance, but also about any pitfalls, and are 9m the cheapest?
Also, i always think about selling at some stage and i'd like to know how it might sell. It'll look and perform like a 965 hopefully and understand good 965's are hard to come by, the car is '93 90k miles, fsh and mint, I paid £21500 for it so with the s/c fitted i'll be into it for £26k. if anyone has supercharged and subsequently sold a 964 how did you get on?

There's quite a famous guards red 964 with a whale tail for sale, that's been supercharged and i think may also have had the compression dropped a little, think it was producing about 400bhp.
Looked like a bargain if i remember rightly. Certainly selling for a lot less than it must have cost to put together...
Oh, and the s/c kit that 9m uses is from Turbo Performance Centre in the US (www.turboperformance.com). Lots of feedback on these on rennlist (all good as far as i can tell).
Search the previous threads on PH and you'll see a few people have had 9m do the conversion, again they all seem happy too.
CYBERFACE - where are you when we need you?

I'd be quite surprised if the s/c will help the resale value, it may even harm it quite a bit. From what I've seen (never properly investigated, just general keeping ones eyes open) modified 911's do not typically get a premium.
I would imagine that people like clean unmodified cars, not those with extra stuff that may, or may not, have been done properly.

If you would like any information on the conversion that you cannot find on our website please feel free to ask me whatever you need to know.
We have already converted a 964 celebration with our supercharger in addition to a 3.8 conversion with RS cams. The engine was live remapped with bigger injectors and made a very creditable 366bhp @ 6330 & 457Nm @ 5010rpm, with 340Nm at 1500rpm; fantastic to drive on the road and made a superb everyday car, one of the best overall package we have done with the power of a 3.6 turbo but with 4wd & no lag.
Our first ever 964 supercharger package was sold to a customer in South Africa who had the engine fitted into an off-road desert racer. At the time the chargecooler package was not available, but in spite of this the engine ran faultlessly for over 2 years in competition and won several events against much bigger engined cars, using the low down torque to full advantage....... at standard compression ratio. I always keep my ill-informed, unfounded opinions to myself, I would respectfully suggest that others should do likewise.
Resale value will not be affected if you simply remove the blower kit and put it back to standard when you want to sell the car, I'm sure that there will be plenty of takers out there for a used 9m supercharger kit at a bargain price.

The chargecooler kit will fit under a standard or RS decklid, there is a water radiator to fit at the front, pipework & pump to get the water moving and the air-water-air box fits in place of the discharge elbow of the blower.
The Celebration has standard C4 brakes, on our conversion we also fitted 3.6 turbo brakes, i.e. big reds.

I suspect the one you are thinking of is this one:
www.shirleys-garage.co.uk/Cars%20For%20Sale.htm
when I was mulling over a 964 early last summer I saw (but didnt drive) this one. the fact that its still for sale some 6 months later speaks volumes for the sales appeal of after-market mods like supercharging.
IMHO the only possible justification for supercharging (or any major faffing about) is because you really want to do it for your own pleasure and because you want to enjoy it and use it for the medium to long term. If youre thinking about resale already, dont go there. money well and truly down the plughole. This applies even more to a "premium" 964 like the celebration model which attracts a higher price because of its rarity value and heritage. I'm sure many of the PH'er dealers would agree that "originality" sells far more Porsches at far better prices than bolt-on mods, which are generally a killer for residual value
That said, Ninemeisters comments about removing the supercharger at sale time seem eminently sensible. Youll get far more back by selling a well respected kit like that privately and the car in its "original" condition than you will selling the two together

As VS implied above, I have the Ninemeister supercharger kit on my car. It's a 993 rather than a 964.
I've just (literally) got back home after driving it from Verbier. The drive back was a bit of a mad charge as the roads were virtually empty...
The S/C makes the car so much nicer to drive it's unbelievable. The obvious thing is the complete change in the torque curve: it pulls really hard from just under 2k revs so fewer gearchanges are needed. On the motorway, indecent progress can be easily made keeping it in sixth.
Bizarrely enough (and this may be attributable to not having to use the revs as much), fuel consumption has improved on motorway journeys.
I wanted to keep my car looking completely standard, so no tail fins or spoilers have been fitted. All 9m's previous S/C jobs have been done to spoilered cars, but they managed to get it all under the existing automatic spoiler / engine cover, without losing any functionality. Whether this can be done to a 964, don't know. However this is still a thumbs up to 9m for doing a great job.
Anyway from my previous posts you may gather that I absolutely love it, and definitely recommend you get one.
Pros:
1. Torque
2. Real world speed (linked to 1 above)
3. No lag!
4. Value for money (£/bhp or lb ft)
5. Makes a great noise
6. Can be moved to another car if required
Cons:
1. Can't really think of any valid points...
In terms of reliability, etc. I haven't heard of anyone blowing their engine up or the S/C failing, etc. Regarding adding boost to an already high compression engine, Ninemeister Colin gave a detailed explanation why it was not a problem in a previous post. Basically the induction kit adds some PSI over atmo anyway at high revs due to the tuned length of the manifold. The S/C is low boost and simply gives around the same amount of boost, but all the way through the rev range, so cylinder pressures aren't way over normal.
The only aggro I've had with mine is that the removal of the old induction gear has exposed the distributors more, so in really heavy rain I'm getting misfires. I'll easily be able to sort this by providing better waterproofing for the dizzys.
Anyway enough for now, email me if you want more info, and go for it!!
