Finally finished base-lining the Porsche today. We lost a month of preparation due to the accident repairs, but finally finished all of the tasks necessary to establish a baseline and get the car out onto the track next week. We even managed to fix the broken vanity mirror on the passenger side visor. The last step in the process was completed this week when we took the car down to Behe Performance to get it on the Dyno. Since we are starting to run out of time before the next trackday, we had them finish the remaining maintenance tasks and put the car on the Dyno to see what we have to work with. They inspected the suspension (nice to get a second opinion after any repairs), flushed the brakes, changed the transmission oil, and aligned the car as well.

The initial results were a bit disappointing. The initial runs on the Dyno showed only 221 hp at the wheels and 207 ft lbs of torque; peak torque band was pretty narrow. After Behe worked his magic, however, horsepower is up to 236.9 and torque up to 217 ft lbs. More importantly, the peak torque band is wider, with more than 205 ft lbs from 4400 to 5600 RPMs as opposed to only 4700-5300 before the tune. The 2000 Carrera had 300 bhp when it left the factory. If you figure a 15% drivetrain loss, that amounted to about 255 hp at the wheels. Considering that this is a twelve year-old car with 68,000 miles that means it’s down about 8% from new. That’s probably not too bad, especially considering the nature of dyno testing where weather conditions and fuel quality can impact results.
