    Cayman Supercharger Kit

    So I've researched as much as I can on this, but it doesn't seem like there is a kit readily available for the Cayman (Ortin was a scam, VFF never finished it, etc.)--does anyone know if there is a kit available or a common conversion from another car?

    After making some upgrades to my car, I'm thinking sometime next year I'm really going to want to up the power--I much prefer superchargers to turbos...can't seem to find a kit though.

    It seems like everyone is very happy with their TPCicon kits, and many people have had them for years, but I would still prefer a SC kit for a couple different reasons.

    Any info would be appreciated

    Ruff is the only supecharger installation I know off. Ruff usually does very good work. They also want a King's ransom for it. I have no first hand knowledge of this unit.

    I'd be very interested to hear the reasons. Turbo lag? What else? What are the pros and cons?

    Certainly--you have the first:

    Turbo Lag

    Additional Heat Generated

    Turbos require more boost to make the same power--exhaust manifolds are extremely hot, so this lowers the power gained...cooler air makes more power

    Superchargers are in sync with the engine--as RPMs build so does the pressure. This has several benefits: smoother power delivery, easier on transmission (as there isn't a sudden surge in power), etc.

    Heat is probably the biggest one though--overall, turbos create a lot of heat in the engine compartment. Much more than superchargers in my experience and understanding of their workings.

    I will check out RUF--I believe you on the price

    Thanks for the quick responses everyone!

    Re: Cayman Supercharger Kit

    first, allow me to acknowledge that i'm not an engineer, and certainly not a member of sae. having said that, i have not experienced any perceivable turbo "lag" with my TPCicon turbo kit.

    another issue you may want to consider is the "parasitic" drain that sc have on the engine as they draw power from the engine, whereas a turbo is driven by exhaust (waste) gas. as i understand, generally speaking, a centrifugal sc will not match a similarly sized turbocharger for power potential or efficiency.

    Completely agreed--for power potential, a turbo is the way to go.

    Buddy...

    Turbo lag, doesn't exist!
    Heated engine, is a concern I agree especially in hot countries. I hope the oil intercooler and radiator upgrade from TPCicon can protect the engine. So my boost controller is off now since the temperatures are on the rise but still have 550HP in my case to torture the streets with.

    Nevertheless, I have to confess... After 2 months you get used to the new power gain. That should be a concern to add to your list

    You have it backwards:
    1) Superchargers require more boost for the same power because of the parasitic power drain of the compressor drive system

    2) The centrifugal compressors of a turbo are more efficient than a positive displacement compressor and heat the air less not more for the same boost.

    Can someone explain why this would be the case? Has someone measured intake temps with two comparable setups on the same car? Being that I haven't personal taken any temps, I'm not denying that this could be the case, however, it is doesn't seem very intuitive. (though I'm by no means an expert on the subject, so it could make sense with the right info )

    I appreciate all of the feedback everyone is providing.

    Re: Cayman Supercharger Kit

    There are a few things that need to be cleared up here:

    1. At boost levels up to ~10psi, turbos do NOT make more power than superchargers (except roots). You need only look at current offerings on the market for other cars to see that this is true (e.g. companies like Active Autowerke make *both* SC and turbo kits for the same cars that make the same peak power at the same boost levels -- meanwhile, the twin-screw is making WAY more power under the curve). However, if you need proof from scientists, look at the NACA experiments, which found the same thing to be true. If the turbo uses "free energy" from the exhaust, then how do you explain how the Borlaicon frees up 20 hp? Exhaust restrictions, including turbos, always rob power. There is no free lunch (except for nitrous ). Nevertheless, for boost levels past 15 psi, I would only consider a twin-screw or a turbo.

    2. While all turbos are fairly similar, there are 3 very different types of superchargers which have dramatically different characteristics: roots, twin-screw, and centrifugal. The RUF unit is a centri, which is the easiest to install but the worst performing at low revs. In fact, the centri replaces "turbo lag" with "boost threshold" in a big, big way. Not that I wouldn't get a centri! Any boost is better than no boost, right?

    3. Twin-screw compressors are positive displacement, yet they have efficiencies as high as centrifugal superchargers and turbos at high boost levels (diverdog is referring to roots blowers, which I agree, should not be used for high boost). Unfortunately, there are no twin-screw kits for the Cayman.

    4. A good intercooler takes most of the heat out of the charge. That means that no matter what compression is used (roots, twin-screw, centri, or turbo), a good intercooler will fill the cylinder with the same amount of air at a given boost pressure. At that point, the only downside to the extra heat is that it is wasted work.

    Re: Cayman Supercharger Kit

    Thanks for the reply wulfgang--as always, very helpful. While my experience and preference lies with a SC set up, it would appear that I would be fighting against the current to pursue that route. TPCicon having a well tested product with plenty of customers makes it very appealing. My car has PDK, so I believe I can only install the low PSI kit (non-intercooled) anyway, so hopefully running such low boost will keep the temps in check.

    Shame I just spent $4k in upgrades or I would be about a 1/3 in on the turbo kit. I think I'll feel better if I waited until the car is a year older anyway--more miles to make sure nothing is wrong with the engine or tranny because after the turbo I'll be flipping the bill even if the engine/tranny was faulty from the factory.

    I wonder how much value my car will lose on trade in here in a couple of years if I were to get another Porsche? (if I installed a turbo)

    I'm still going to get a price from RUF on Monday, but I have a feeling it will NOT cost less than the TPC kit.

    Again, thanks to everyone for providing info

    Re: Cayman Supercharger Kit

    The RUF supercharger is (or was) 16,750 euro for kit and 5,750 euro for install. No comparison to TPCicon on price, for sure. But it's RUF!

    Yikes!

    Well that will seal the deal for me. I actually called and talked to TPC today about a kit--I've seen many posts and recommendations from members, but they answered all of my questions and concerns (not surprising considering how much testing, etc. has been done with the kit). I really do wish that there was more than one option available, even though TPC has a great kit, it's better for consumers when there is competition.

    So I think I'm decided...I'll most likely wait until winter to get it done (12-13k will take a little saving )

    I really do think that if someone can get a low boost SC kit available for less than 10k, somewhere around 6k there is a market to be had. Sure it wouldn't have the bone crushing power potential, but it would give a very nice increase in power, would cost less, and less complicated than a turbo kit.

    Anyway, thanks again everyone for the info and feedback.

    Re: Cayman Supercharger Kit

    I would love the instant power from the roots, but would not be a good fit with how high our motors rev. (huge parasitic losses) A twin screw kit would be awesome but not sure there are a lot of those floating around. Eaton M90 are dime a dozen from various factory supercharged cars.

    What kompressors are used on the Mercedes?

    Re: Cayman Supercharger Kit

    The installers make a difference I would go with TPCicon, or Accumoto, the closest one, and I would budget more money for the installation. There are some nice things worth installing at the same time. Things like wrapping the exhaust, or maybe some gauges etc.

    FI unfortunately kills intake noise, which is a pretty nice sound on our cars. Nitrous preserves the nice sounds, but a 10 lb tank might last... what... 5 laps on road course? On the other hand, who needs that much power on a road course?

    Wishing we had a product that gave us the ability to adjust injector pulse widths per RPM and remap the MAF/spark table. Once the electronics are mastered then just mechanical engineering to get the parts to fit.

    I think the 2004-2007 Saturn Ion Redline and Chevy Cobalt SS had an Eaton M62. And the 2003-2004 Mustang Cobras had an Eaton M90 I believe.

    EDIT: The Cobra actually uses the M112. Jaica: Thanks for pointing that out--I'll talk with TPCicon again about some other items that would make sense during the install.
