Supercharger for 2.5 - 986 Forum - The Community for Porsche Boxster & Cayman Owners

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?

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.

On our first prototype car, the customer came to pick up the car ahead of schedule. The pipes we had made him were the only set we had, so with him waiting in the waiting room, we had to pull everything off the car, copy the pipes as best as we could (so we could send them out to be plasticmolded), and put the car back together. We put it back together quickly, which was a pretty fast dry run, at 5:30, i pulled it out of the shop, he hopped in it, and drove NONSTOP from Kansas City to Arizona. So yes...it will make the trip. This isn't something we like to do though, I like to have an extra day to make sure everything checks out etc to ensure no issues, but so far there hasn't been one in all the times we have pulled the kit off and put it back on with the 2 cars that have been prototypes.

The air intake is an evo cold air intake, which is connected to the custom intake pipes for the supercharger, etc. The headers and cats and o2's stay the same on the 2.5L. The spark plugs stay the same as well. When done inhouse, we will flash the ECU through the OBDII port and takes about 20 minutes. Out of house, would require the installer to pull the ecu (takes but a few minutes) and send it to us to flash. Turn around is a day or 2, so if it is pulled at the beginning of the install and sent out, it will be back quickly. With that being said, if there is a good audi shop, they should be able to handle the install without a problem. I personally am not a big fan of working on audi's, so if you can work on them, you can definetly do this job

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)

Because with a SC you will tend to be going faster more often. A brake upgrade isn't so much to increase braking force but to allow you to "HAVE" brakes for a longer period of time. Think resistance to fade as the main reason to upgrade when you add gobs of HP.

Because it is a perfect excuse to slap on a pair of Big Reds

In response to the loudness again, the supecharger is a Procharger supercharger, they have arguably the best supercharger out there, and compete directly with Vortec. The supercharger sits about 2 feet from the driver, even with the sound padding between the driver and the blower, you are still going to hear it.
