I know about the NRE turbo set ups. Very cool.
After careful examination I concluded that the CalTracs were the cause of the sparks. Adam was in the back and when I get on it it really digs and I only have a couple inches of clearance with them. Maybe I'll build skid plates?!
I like our truck, too, crazy fool. You totally smoke-screened me at the light, a'la Spy Hunter. I was blinded by the smoke and by the time it cleared you were out of sight.
