Note the excellent Air/Fuel ratio at 12.4:1 thoughout most of the boost up to 5700 RPM, where we start adding a little more until we reach 11.8:1 at redline and full boost. We do that to cool the charge air and add engine safety.

We also did a pull with the air filter/cold air system removed and gained only 4 HP. This is normal - all air filter media is necessarily somewhat restrictive in order to function, and a drop of about 4 HP is the lowest you can reasonably hope for. Higher drops with the air filter/cold air system removed would indicate that the air supply system is poorly designed and restrictive. We were very pleased with the 4 HP drop.

I did take a video too... in-car and out-of-car. I hope to find time to edit it and post it this weekend so you can hear what it sounds like.

CONGRATULATIONS. Your car now has more HP than a Nissan 350Z (6 cylinder) and a 1978-1984 Porsche 928 US (8 cylinder) and a Ferrari 308 and 328 (8 cylinder). I have supercharged each of these cars.

The next step for us is Manufacturing and writing the Installation Manual. The parts on the car are one-of prototypes. Now that we confirm they work and there is no belt slip or noises or interference, they come off the car so we can use them as patterns to make more.

This is when we will be able to quantify the cost of manufacturing the kit and get you guys a price.

Thank you for your interest! If you have any questions post them here and I will get back to them. Right now I need to jump back into the shop and catch up on some race prep for an event on Monday.

I was thinking I would install water injection and now is the best time to test the car with the water injection to see if I see a performance boost with it operating. It's the best time for this test because it's very hot out. When I did this with my Saab which had knock sensitive boost control I could see the boost go up when I turned the WI system on. For the 968 I would expect to get more spark advance and better performance with the WI system running, but nothing I can easily measure (unless there is a way to datalog spark advance on the street?)

I have a G Tech Pro Comp which seems to have died and a dyno app for the Droid I have not tested yet.
