[quote name='jeffski1' post='61756' date='Oct 16 2008, 10:27 AM']Bravo Kunz. I really like your pictures and the work you are doing. I have a supercharged 968 as well, however, mine has an Eaton M90 roots type supercharger. It has been an ongoing project for over 4 years, but I am happy with the car and happy to keep trying to improve upon it. Recently, I met up with Flash and some of the advise he wrote about above comes from the installation mistakes he observed on my car. For instance, when the intercooler was installed (by SFR none the less), noboby thought about airflow through the radiator. They left a tapering 1" to 4" gap between it and the ac heat exchanger, which is about an inch infront of the radiator. Here's a quick picture of the poor install.

Here you can see the bottom of the IC on the left, sloping further up to the left, then the thin A/C heat exchanger, and then the radiator (well...the bottom supporting bracket). Notice the small gap Porsche leaves between the A/CHE and the Radiator? Maybe an inch. This close proximity allows the air to maintain its velocity through to the Radiator. The result of my install is very poor airflow. That HUGE pocket behind the IC causes the air to swirl around, trapping the air, killing flow. Duh. The swirlling air creates a barrier to air flow. It took Flash two seconds to point that out, while three "expert" shops missed it completely. Especially frustrating because I was having over temping issues early on and every one of the experts just scratched their heads, eventually talking me into buying a new radiator. Oh well. It is a better unit, but was probably unnecessary with a proper IC install.
In talking with Flash, I think I would like to explore mounting a 951 IC in the location used by the 951/968 turbo, up and away from the radiator. Flash was telling me our cars already have the mounting brackets in place for it. My system doesn't run a lot of boost, maybe 6.5psi at most, so I don't think I need as much cooling as my current IC provides. In fact, I may even remove the IC all together, but that's a different story.
The second issue with my IC location is that what air does flow through to the radiator is quite a bit warmer then the ambient air, passing first through the IC, then the A/C Heat Exchanger (and I use my A/C as I've lived in Phoenix and now LA), then finally to the Radiator. Consequently, my car always runs near the 10 o'clock mark on the temp gauge. Not necessarily bad, but certainly warmer then normal.
Well, like I said, it's still a work in progress. And I love it. Best of luck on your project.[/quote]
Jeff your situation is alot different then Kunz.The intercooler placement of our kit was done like that for a couple of reasons.A. routing the intercooler piping.As you can see Kunz had to cut up his car to fit the intercooler in the "correct" postion.B.it was designed for non A/C cars (and we had lots of feedback from racers who did not experience overheating issues)but we adapted it to your car with A/C and a Roots Blower.C. Costs was also a concern as Tony G had contacted us and asked us to keep costs down to a minimum since he felt slightly obligated about the supercharger and tuning issues.Remember when your car came it was detonating at 4 psi with water injection.When it left it was running 6-7 psi if I remeber correctly and it was not detonationg,running much stonger and much safer.
Originally, your car dynoed at 232WHP(27 more horsepower then a stock car) with 4 psi, detonating and the igntion timing retarded tremendously.This is how it was brought to us.It was about to blow up!!!! If you think removing the intercooler and implementing the Aquamist is going to magically work this time around,I think you are mistaken.If you think you would get anywhere close to 270WHP with no intercooler then you are not being realistic. The compression is too high,91 octane gas sucks and the roots blower have an extremely high discharge temp.Makes it difficult to work with, let alone make power. When your car left I think it was making around 270WHP.That is a big improvement. But if the "experts" can figure out how to remove the ic, run 4 psi and not detonate and actually make more horsepower then a stock N/A car then more power to them. Using a stock 944t intercooler would be great if you can find the obsolete twin hood latches from a 968 turboS that mount to the sides of the fenders and reconfigure your exsting hood latch,cable,etc.....but good luck with that becasue it is going to be a project.
Apparently there has not been any major problems because I am sure we would have heard about it.As far as your temp gauge goes and the reading you are seeing,it might just be the gauge or a bad ground.The factory temp gauges can be decieiving sometimes and not always accurate.Your post sort of upset me a little because you make it sounds like we are a bunch of idots who dont think about airflow and we did nothing but try to take over someone elses project and make it work for a little money as possible. It is not like you had mentioned us reworking the supercharger intake, intake manifold to accept an intercooler or tuning the car properly so it wanst a hand grenade or anything like that.There was nothing said about us troubleshooting the leaky Aquamist system.It was all negative.If you wanted us to mount the intercooler like Kunz did,we would have gladly obliged and charged you accordingly.
