As you will probably all know already, we quote the standard 9m supercharger kit power output as 350bhp on a standard engine but we regularly see 360-370bhp on a fresh motor. However following an inpromptu discussions with the supercharger manufacturer whilst we were displaying the car at Autosport International in January, he convinced us that running the blower faster would get us the right side of 400bhp. It seemed rude not to try it.....

The changes that we have had to make in comparison to the stock kit are:
1. change stock 6 rib to 7 rib poly-vee belt drive pulleys
2. larger injectors
3. Cat test pipe
4. Larger Air flow meter

Ik doe niks motorisch aan mijn wagen.
Ik ben er zeer tevreden over en nu is zij perfect. (Zowel kilometers als OB als gebruik en verbruik)

Ik neem aan dat de 16V kop vervangen is door een 8V kop, aangezien (hoge) drukvulling niet samen lijkt te gaan met de 16 kleppen. Dat verklaart ook waarom de 968 Turbo (S) gewoon 8 kleppen heeft.

968 Turbo S
Front longitudinal inline four cylinder water cooled 16v VarioCam, KKK Turbo
2990 cc
305 bhp (350 bhp for Turbo RS)
6+R,sync rear drive

The car with it's 3.0 litre 4 cylinder engine and only 2 valves per cylinder featured a K27 turbo, the cylinder head was similar to the 944 Turbo S, rather than using the 16V 968 head.

Sorry , maar die gegevens kloppen niet.
Het is wel waar dat voor de racerij regelmatig de 16 koppen vervangen worden door de 8V kop, maar de 968 Turbo S is wel degelijk standaard met een 16V kop geleverd

Je hebt gelijk, er lijkt inderdaad een standaard 968 kop op te zitten

Gek... alle ervaringsdeskundigen zeggen dat het niet kan Of misschien toch... voor een paar ritjes dan

Interestingly we exhibited our 968 at the Autosport International Show at the NEC at Birmingham in January, at which we had a visitor to the stand who had been part of the 968 development team at Porsche. His comments were that the team had designed the engine with high compression/low boost in mind, hence why the heads has such large intake ports, but because the results were spectacular Porsche had to cap the project for fear that the 968 would outperform the 911 and damage sales, so a hasty redesign took place which resulted in the production 968 engine that we now know. To say that he was excited by our results was an understatement.

Nee, af fabriek hadden ze 8V
