3/21/07: Today is Saturday, and I brought the car home on Thursday. The mechanics of the car are now complete. I have just 180 miles on the motor as I write this, so I have not used much boost yet. I will wait until there's at least 500 miles before using modest boost, and probably 1000 miles before I go for full boost and RPM.
Below are some photos my son John took, and at the bottom there is a little video clip to demonstrate the sound of the TCD exhaust.
