was on my way to Datusn/Nissan event in the NW (The Blue Lake Park event) and passed 15-20 510's on the I-205 (was in a hurry to meet up with our Z club). While weaving in and out of traffic to get to our pre event meeting place I noticed a red 510 hanging behind me... I stayed on the 205 as he split and went the I-84. Apon arriving at the event he came up to me and said "this is the Z I was hanging with". It was the fastest 510 I have seen in action. He was still having probs with tuning. One of our Z club members built the car and the motor before the currnt owner bought it.
