12/8/2003 - UPDATE! I appreciate everyone's compliments and interest in the car. I will try to update more of the sections soon...for now I've added the following:
-More of the 'Experience with Tuners' story.
-Latest pictures taken LAST WEEK, December 2003. See them on Page 6!
This page is dedicated to my second Porsche - a 1992 Amazon Green Metallic 968 coupe. I've owned this car for 3.5 years and it's changed significantly in the time I've had it. Here's how it looks today:
These are recent images detailing the exterior changes of my 968. The front bumper has clear turn signal lenses and white indicators. These European style lenses are longer and replace the small bumper pads on North American 968's. Below the front bumper is a 968 Turbo style splitter made of fiber glass and painted body color. The rear has a 968 Turbo style adjustable rear spoiler also painted to body color. The wheels are 17x8 and 17x9 forged Speedlines distributed by Ruf in Germany.
These images don't show the modifications to the engine. I will describe what was done in short down below and in further detail later. Here's how the site is organized:
Page 1 - You are here.
Page 2 - The car when it was new.
Page 3 - My experience with tuners.
Page 4 - Engine modifications in detail.
Page 5 - Exterior modifications in detail.
Page 6 - NEW PICTURES 12/03
I will amend this cover page with updates as they are made to the car.
Last spring the car was dynoed to dial in the air/fuel ratio after installing a custom chip. To my surprise the curve was completely flat at 11.6:1 from 3100+ RPM's. I turned the adjustable fuel pressure down 1 turn [~4 psi] and the air/fuel ratio now resides at 12.2-12.5:1 in the same RPM range. If you're unfamiliar with tuning then you'll be shocked to learn that adjusting my fuel pressure a little bit netted 10 horsepower and 10 lb-ft of torque above what I had before.
Back in February my car was dynoed at 251 RWHP and 238 RWTQ with 4.5 lbs of boost. Why only 4 psi? The original engine has never been opened and the forged crank, rods, and pistons along with the 4 valve per cylinder head are good for 11:1 static compression. Obviously the engine compression is too high for generous amounts of boost to be run so eventually I'll be purchasing 2mm shorter custom forged rods for 9:1 compression with factory 968 Turbo piston rings. I plan to remain conservative at 11 psi on pump gas which should net ~325 RWHP.
