CARB will come at a later date. For now it is not. As easy as the install I would simply pull the unit out. It would not pass visual if you did not and the whine of the SC is to say the least not stock sounding.

The TIP will handle the added power. We have seen no issues with the 986 or the 996 at these levels.

The 3.2L power gain is yet to be seen. As soon as we get JP's car done, and get some miles on it, we will dyno it and see what kind of power gain we get. IIRC we got a 38% gain on the 2.5L, so we are hoping to stay around those kind of gains on the 3.2L. As far as people in europe selling it, that is a possibility, obviously we will have a few certified installers throughout the states other than us, and this will probably extend overseas when we get to that stage.

PorschePhD & PorscheDoc, I live in Texas... would I have problems passing the smog test here? I know CA is far tougher than Texas, but I'd hate to spend this kind of money only to find out I can't easily pass a state inspection each year.

Having a CARB number and actually having clean enough numbers are not one in the same. CARB is a mountain of paperwork, expense and testing to ensure that the state of CA is happy on all levels. Because a product is not CARB certified does not mean that if one was to go to a testing station it wouldn’t pass. From a emissions level standpoint it will pass on the idle and on the rolling (dyno) test. All readiness status checks read ok and the levels are within state passing levels. So in long the answer to your question is you would pass

I live in auburn, alabama and would be very interested in having one of your superchargers on my 2.5L 99model. However I would be very leary of having the work done somewhere less experienced at dealing w/ a porsche. Do you guys have regional install shops?

[porschephd]

I can't say that we have anyone in our neck of the woods yet. We actually get a few cars from your area now for upgrade work. I do think that we can walk/instruct most competent shops through the process.

There is one audi performance shop here that is top notch, I would think w/ some guidance they could perform the work. I would hate to be the guinee pig for them though. Of course a nice long road trip would be exciting. Would the newly installed supercharger be able to handle a 1000+ mile trip so soon after being put on? Two more questions: Is the entire ecu pulled and replaced or do u flash the upgraded fuel/air delivery ratio through a cpu linked to ecu? Does this whole procedure require any replacement sparkplugs, O2 sensors, header/exhaust piping, or air intake changes, and would need to be done at the same time or before hand? I'll most likely direct my future questions to your place of business.

Question- why am I upgrading my brakes if I add a supercharger? They stopped from speed X fine now, I just get to speed X faster (how sweet is that)
