This weekend I saw the 02 Z06 at the Spearfish meet. He dialed in at 8.9 so I assume he was running a little slower than that. It was a hot day at high elevation so none of the times were very good. I ran a best of 8.7 at 83.8 mph. I have a rm twin flow intake and drag radials on my o1 Z. I only saw one other 01 Z run and he ran an 8.9 at about 80. I think he had a different intake but stock tires. Two ZR1's with chip, intake, and exhaust ran 9 flat and I dont know the speed. It doesnt appear the 02 is much faster than the 01. I would say their only advantage is the new cam cause the other things like the intake are usually replaced and the pre cats can be removed on ours and the screen taken out of the maf.
