Enjoying following your thread. Thanks for taking the time to post everything.

Supercharger instal - Kunz - 10-28-2008

Thanks for all the positive reactions! I love it too; only to look at it is a pleasure!

Darth:

Nice to read from you! I hope to be able to take some pics soon to show how we did that. But basicly there is a nipple in the up-pipe going to the SC same level as the tube for the blow-off. There we also took the line to vent the engine ;-)

Supercharger instal - Kunz - 10-29-2008

...Ok!

I just come back from visiting my specialist and the 968. They changed the sealings of the power-steering-pump and instaled the under engine-bay cover, the front part between bumper and chassis traverse.

The work is a bit stock right now because we are waiting for some more parts to arrive; a new constructed flywheel, steel, only some 5.9kg of weight. I used to have a factory lightweight steel flywheel (racing part) that was only 7.4kg, replaced it by a fidanza aluminium flywheel of about 6.8kg last year. The problem was that when the car was really hot you could only change gears (especially standing in first or reward) using pure violance. We think that this is caused by the fidanza...

Anyway, I will get now a real high-end product which my friend and specialist is also using in the racecars, a special steel, very light...

Unfortunatelly they expect to finish manufacturing at the 9th of November. So me and all of us have to be a bit patient to really see the car run.

Keep you all informed!

Supercharger instal - flash - 10-29-2008

that seems like a lot of work to create something that is already out there and already works - have you looked at the flywheel at rs barn?

the fidanza i have is 5.8k - no heavy shifting issues in 25k miles - however you must be quick about it, and blip the throttle to gear match on downshifts

the rs barn unit is about 8k (same as the porsche motorsport) - less of the requirements of the fidanza

Supercharger instal - Kunz - 10-30-2008

Well Flash, I personally would have reused the Porsch steel part. But my spezy is a real perfectionist sometimes. It was a suprise for me to hear from the development yesterday. Sure he doesnt start from totally new. He made lots of development (especially the material) for the racecars. He never uses aluminium in these. Dont get me wrong, for many this is great...

Anyway, here some pics of the car again:

First another pic of the brace where you can see all the bee-legs...

Further you can see the under front cover in place now, also how nicly the airfilter is placed there. After changing the flywheel the rest of the cover will sure be attaced too. Then I also tried to take a look up to the compressors intakte where the above mentioned nipple is (there we go for ideling-valve and venting the engine). To finish for today an eye full from the front; the ex-hole for the snorkel acting now to let air to cool in. As said befor we might open up the other side to and will construct a cover from there over the coolers to canal the air through them...

Till soon and with best regards!

Beautiful job! You must be anxious to drive it, good luck, Bob Blackwell.

Supercharger instal - Darth Coupe - 10-30-2008

Looks great Kunz. I know the nipple you are talking about and the one in the picture is the one that I used for the oil filler neck vent. Sounds like I need to get a Y fitting to put both the idle control valve line and vent line on that nipple. It would be better being on the intake side of the compressor. Thanks.

You may consider making a sheet metal shield for the MAF and air filter to protect it from debris.

Great work. I can not wait to see the numbers.

The belly pan acutally covers the air filter and MAF pretty well where it is installed.

Supercharger instal - Kunz - 10-31-2008

...yes, and the rest of the under engine bay cover - the rear part - will cover the whole rest. Also there is a new made splitter behind the bumper to stop the air from goint around the IC / radiator there as well as will keep debris away from the filter together with the remaining front cover and the complete engine bay cover...

First we opened-up the bumper, took out the black plastic inlay, but we decided there would be more then enough air and no direct water / debris shower on filter / MAF with it in place. So there it is again. The filter then is a bit like in a box and will get most of the air from behind. In this application a RAM effect does not seem to be most important for the system to work.

Hi there!

As told I post some pics here of the instal of the SFR SC-Kit:

First you see the old intake and the new snorkel.

Then there ist the modified IC with 90°-turned outlet and the optimiced piping and our own brackets to hold the IC. Nice, arent they!

As we place the IC differently we had to modify the front chassis traverse which of course will be painted blue in the end.

Also I told you about the SFR-bracket that wouldnt fit, so here you see the modified bracket. After everything is finished we will fix-drill-srew that in this position. Also you see how little room there is left between charger and Chassis / trottle body.

Kunz,

The bracket does fit.There have been over 25 of these units sold for the 968 and you are the first to say it deosnt fit.All the brackets are the same.I think where you ran into a problem is that you need to clock the supercharger compressor housing by loosening all the small 1/4" allen heads around the perimeter till you get it to clear the TB and sit correctly against the A/C delete bracket.It is opretty simnple and it looks like from your picture,the SC is still clocked the way we packed it in the box.Just and FYI.Because modifiying the bracket and all sorts ofstuff seems like a real pain.

It looks good all the same.

If you did have any issues like that,you should have called or emailed us fro some tech support.That is what we are here fo.

Hi Tim

Thanks for the positive reaction also!

For the rest:

I dont feel like this is the right place to talk it out...

Just let me tell you here that we tried everything befor changing the bracket.

And further: It is our nature not to look for obstacles and hurdels but find a solution and a way. That's just what we did...

After all the SFR-kit is for me still a good base to start from; a lot of things we didnt have to do... and still a bit of work to get everything where we want it.

Sure if you want more infos about the how and the why I will explain in a PM. Let me know...

Best regards!

Unless there is some difference with your non-US car vs. some of the other non-Us cars, I cant see there being a problem with the fitment of the bracket and sc but if you want to send me a pm about it, I would like to see what you encountered.

[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.

Hi There!

Some more weeks and months have passed and some important things have happened like my wife is pregnant with our second child, we brought a house... and the flywheel arrived!

Those who followed this thread know that we also planed to change the Fidanza Alu unit back to a steel unit that should be even lighter. Unfortunatelly the process of letting them manufacture in Germany took months! OK, right now buissnes may not be easy and getting some flywheels done may not be very attractive I understand... and we could not have tuned anything further as we have real winter here in Switzerland... and some more important things happened in our life. But I most say: a very long time!

Yesterday the stuff finally arrived. Unfortunatelly I didnt have the occasion to weight the reallywell finished unit but if I compare to my old Cup-Flywheel which has some 7.5kg it is significantly lighter and must be well under 6kg.

On the pics (again just handy-taken; sorry for the quality) you can see the old Clupsport-steel-unit and the new one. In about 2 weeks timethey sould get everything fixed and FINALLY start to tune the car.
After everything runs properly then I plan to get all testet so it will be street legal...

Til soon!
Kunz

...and the other two pics!

I just seen this.The nipple on the SC intake is supposed to go to the crankcase vent but can be capped off if you are using a catch can.Do not put a tee in this lne and connect it to the ISV and intake manifold.The intake manifold fitting should go the the ISV and form the ISV to the charge pipe just in front of the throttlebody.If you tee the crankcase vent into the ISV and intake manifold you will have way too much crankcase pressure under boost and blow oil everywhere!

ISV= IAC or idle control motor.From what it looks like Kunz is trying to connect the IAC to the crank case vent and the intake manifold!
