968 Supercharger Kit Development
#556
Going from my 83 944 to a 968 was a big difference for me. I am sorry I missed the 951 step for comparison. I absolutly love driving my 944 and 968. Both cars do what they are suppose to do, that is make you feel like you are driving a race car. The thing I really like about the 968 is that people are a little scared of it. Not nearly as many asses want to race it. I don't drag race but with the 75HP extra on the 968 there will probably be very few cars that will pull up next to me that are faster. I think Carl has produced a great kit for the money and ease of installation. I do not want to bring up this discussion again but I also think the kit is modest enough that the car can handle it without doing other mods that can cost big bucks. All things considered I believe this kit balances everything out nicely. Now if someone would just loan me $4K so I can order it. I just do not have my wife convinced yet that I need it.

I am not trying to start a fight with anyone, or have met any of you. I had my 944 and 951 in Saudi Arabia and then shipped them to Finland. I have since sold them and bought a 968 in Spain. My point was that this topic was about the development of a product which would give more power to owners of 968´s. I am currently not interested if it can beat a 951 (in 951 standard form it should have 100 HP extra, with a good 968 engine)(sorry had to throw that in). My interest in this topic is to see if I can develop a good road/track 968 which will give me the pleasure I am looking for.
I am not here to diss the 951, although after I had rebuilt the 944´s suspension, steering and brakes, the standard 951 could not hold a candle to the 944, except in terms of power. Here comes the sacrilige, neither could hold a candle to my M3, which has much more power and much better handling. My aim is to bring my 968 up to the level of my M3.

OK, so back on topic -- what's the latest development news? Anything interesting happening on the S2 front, for example? Any plans for an intercooler stage 3 kit on the horizon?

The S2 with our kit in it is out and driving around, but I'd be better to let the owner post and tell you about it than me. I can tell you he had to remove the flip-up headlights and install a projector light kit with lexan clear headlamp covers (there are two such kits for the 944 on the internet) in order to get the room he needed.
We already knew how important it was to keep turbulance form the hot-wire sensor, but he had to mount the sensor even closer tot he supercharger than we do in the 968, and the turbulance became a problem at idle.
I am working on a directional screen for this application that will cover the MAF and protect it from that turbulance on later installs.

This discussion of the MAF raises an interesting point: The S2 engine (unlike the 968) doesn't have a MAF, it has a "barn door" style AFM as stock. At this stage, I guess it unclear as to whether a "true" S2 (i.e., one with a S2 head rather thana 968 head) would run the kit with the AFM, or whether a MAF conversion of some dsecription would be required.
If you are going to the trouble of fitting a MAF, maybe you would just go straight to a MAP set-up instead?

The "barn door" air flow meter is indicative of the Bosch L-Jetronic fuel system. I have experience supercharging L-Jet equipped Porsche 928's, and I am sure I can fuel it no problem.

Why not go Map?
Sounds like you've got some nice parts / kits going Carl. Good for you and I'd like to go in one of these cars one day. Unlikely in these parts.
I'd be tempted to put in some lower c/r pistons and up the ante a little...er...lot...

looks very good.
food for thought.,for those cars with AC,in fromt of the radiator there is the
a.c.condenser.
from the proximity of the MAF and air hoses ,the a.c cond will not allow it to fit.
Any thoughts on this?

looks good. when do we get test results?
It would have been nice to utilize the stock air filter, but it's quite understandable there's not much room to use, and air filter box takes a lot of it in its stock form.
