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

porschephd · 01-07-2006, 05:15 AM

Anyone have any questions please feel free to ask. We designed the supercharger in house and have done all the testing here in KC. The kit that EVO will be selling will be the kit developed here in house so all the numbers, stats and pictures you have seen on our kit will be the same from EVO.

The kit is going to be about 7K not installed. You can figure about a 7 hour install at the most. It is pretty straight forward. The 2.7 kit is not finished as of yet, the 3.2 and 2.5 are about completed for release. The pipes presented some issues and had to be remade to ensure that the install and reliability remained in tact.

Sorry, haven't been on the board in the last day or so, so late reply. Like PorschePhD (Stephen Kaspar, who owns Imagine Auto), Evo motorsports will be installing the kit that we designed in house, so it will be the same deal. I can't remember what all we discussed in the last topic about the SC kit from about a month ago, but like Stephen said, the 2.5 will be 7k plus install. We still need to do a couple of dry runs to determine the exact amount of labor needed, but it will not be as extensive as our 996 kits which run about 17 hours. The 3.2 kit which we are still working on, will be about 8k plus install due to the addition of custom headers, which we are still working out. The front O2 sensor sits in the way of our SC on those cars, so we are in the process of redesigning the header system on that engine. In fact, i believe our guinea pig headers showed up yesterday for us to start cutting and modifying. The 2.5L kit picked up roughly 100 horses to the wheels at about 4psi of boost. This is determined to be a safe level of boost for us to run on the engines, and we have done extensive tuning with the program to ensure proper power, air/fuel ratios, and proper power curve. The supercharger runs at a very minimal rate when compared to what it is capable of, so the system is very under stressed. In our 996 kits, (which evo designed and built, and we sell and install), we also run 4-5psi and those kits have been bulletproof. We have cars with 50-60k miles on the kits with zero issues. This is something we are very familiar with, i have 2 996's in the shop right now that i will install superchargers in this coming week.

Like Stephen said, any questions, let em fly

What about CARB approval? See we have a pesky thing in California called a smog inspection every 2 years and if the guy knows what he is doing and looks you flunk the visual inspection. They get out a floor mirror and flashlight.

And our smog is now done on a dyno. Even if the inspector did not look then the emissions may not match the specs and you flunk.

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

hi Doc
as mentioned previously, will the tiptronic support such an excess power on the 2.5 or other models for that matter and what will the power be on the 3.2, also will someone sell it in Europe at any stage?

thanks
