supercharger questions

I know this has probably been asked before, so I appologize in advance if it was. I have a 3.6 C4s and am seriously consideringthe supercharger kit. Do you guys have any input as far as reliability, performance, negative effects on the car, etc? In other words, yay or nay? Also, is EVO the only company that has a kit like this?

You might want to do a search. There was a couple HUGE threads on this. For the most part, they are very good and actually increase gas mileage. They are also, VERY expensive. Chad

I thought about it and went against it, just question the reliability, esp as much as I track my car.

wow..the search function is great! thanks!

I've been wondering about the reliability as well. Don't recall seeing any datapoints on that. Anyone have any negative experience to report?

Supercharged for a couple of months now. LOVING IT!!!! No problems to report whatsoever.

Do you think that the frequency of the supercharger threads will ever hit an equilibrium with the frequency of the RMS threads? Just for the sake of mischief, I think I will start trying to link the two issues. That should start some real flame wars

Go with EVO's system. Todd has designed a modest and safe system that is very reliable. I have no problems with mine.

This the same X-Ricer from the audiworld forums? -KJ

I havent seen a RMS topic in a while, we shouldnt go there ,some really sesitive people out there! I am going to do a EVO supercharger kit. You should know that it voids the warranty , but if your Porsche dealer does it, they will still cover everything BUT the motor.

Ruf actually upgrades the motor to sustain a sc, that's why they warranty the motor for two years and evo doesn't. That's also why Ruf's is 20K, you get what you pay for I guess.

RUF huh I think i will look into that Chris..... thanks man!

If I was gonna do it I'd Ruf it up a bit!

Where have you read this? I read the official RUF product release announcement and they just described a bolt-on unit like everyone elses, no mention of beefing up anything or warranty.

If you contact them directly and they will tell that based on the engine milage and condition it will get rebuilt with new bearings etc. That way they can warranty it.

Call Ruf directly, they'll tell you all the details.

...yep - the RUF SC kit seems to be the business. Am investigating it for my car and have been in correspondence with RUF. Their kit has been two years in development and comes with a 2 year guarantee! They have kits for all 996/997 variants (manual and tiptronic).

The problem with RUF is that it is about twice the bucks, and half the power, if I remember right. (If not, someone please correct me) Now, that being said, I suspect strongly that it (RUF) will prove to be more reliable than the EVO unit. But, the question is by what degree? If the EVO unit is 99.9% reliable, and the RUF unit is 99.99% reliable, then the RUF unit is ten times more reliable. Sounds impressive, until you realize that we are talking about the difference between 1 unit out of 1,000 failing versus 1 unit out of 10,000. At that point, the cost and power issues completely swamp the reliability, IMHO. BUT -- please note, the reliability figures I just gave are purely hypothetical examples. I have no idea (yet) as to how reliable the EVO unit will be, or the RUF either. I just made those numbers up as examples. It could be 50% reliability, for all I know. (but I seriously doubt it, based on conversations I've had with folks who put the EVO units in, some as long as over a year ago) =Carlos= P.S. On a personal note, my EVO SC made it through it's first track day today, with no problems.

You know... reliability might not be the only issue. RUF is going for durability as well and its about fisics if an engine is stressed by its state of tune (or its use) it won't last as long or eventually something will let go by fatigue. I'd definitely fit an Evo SC on a $40K 99' 996 but I'd fit a RUF on my 03' C4S specially because here in Portugal a 03 C4s is worth $105 K (yes its correct and it costed new $168K).Just my .02 though...

Yes, that's the same email that I got from Marc back in early February. It would be nice to hear from someone who has installed one of these. I'm sure it's a quality product, as are most things RUF. My EVO SC made it through a second day of DE, no problems. I have good news: my '99 C2 cab can now officially keep up with a TT cab -- I actually passed it and never saw it again. That was fun! =Carlos= P.S. To be fair to the TT cab driver, he had the added burden of having an instructor with him. I didn't have an instructor, but I did have my hardtop on, which he didn't. But I think I still came out ahead (less weight) as far as "extra" weight goes, and way ahead as far as total weight, of course. I'd like to run against a TT coupe -- that would be tougher. Anybody with an SC have any experience doing that?

Carlos: Congrats on the new SC! I think you're going to really enjoy it. I'm considering going to the meet and drive starting at Rockville Starbucks at 10am on Sunday. Are you thinking of going? There's a thread with details on the event somewhere here if you're interested. Regards

Hey Mitch, Sorry, I can't make it, I'll be at the Preakness all day Saturday, and have to hang around on Sunday to make up for it. Some other time, I hope. Re the SC: you're the guy to blame for my getting it -- not sure if I would have bitten the bullet if you hadn't had yours sucessfully installed at Intersport. Thanks! =Carlos=
