The base/z51 corvettes arent meant a s a competition for the old Z06. Compare apples to apples. The new z51 compared to the old z51 is the change you should look at ....then compare the new z06 to your car.

Folks are trying to figure out what the real world differences are between these two almost identically rated motors. This was a topic of great debate back in 97 between the LT4 rated at 330HP and the then new 345HP LS1. Folks back then weren't seeing much difference between the two motors and many LT4's actually showed more power on dyno's and even at the track. Hell I got my clock cleaned in my 99 MN6 by a bone stock 96 CE. So from my perspective the LT4 was a very "under rated" motor and most folks came to the conclusion that GM sent of the C4 with a "wringer" not wanting to cast a shadow on the next generation motor. Was this reality, urban legend or a vast right wing conspiracy - who knows, but to this day LT4's out perform many LS1's.
That's why I love the CF and have since 1999, we can have intelligent dialog w/o the ranker.

Not trying to be argumentative, It's just up until now I have heard numerous accounts of Z06's trouncing the new C6 both on the street and track.

Of the two that were worthy, they couldn't get out of the mid 8.5's and they ran a lot. We all had great launches.
The track is at 1200 ft. Doing the math based on another time slip I saw here the factor for a C6 was 1.51. Adjust for altitude and it comes out to about a 12.55 qtr mi time.
Nothing special there either. With stock Z's typically running 12.7 +/- a few tenths, it is right on.
The only mod on my car is K&N filters and I really don't think they are doing crap.
The track is real addictive for sure. Can't wait for the cooler weather.

Cool, deal. Sounds like the C6's have a lot more potential than most of what i have heard. I for one really like them. I do think they look a little lifted from the factory but when lowered they look awesome. I am trying to talk my cousin into buying one. he wanted a Porsche 911 (non-turbo) but I told him to buy a C6 or 04 Z06. Anyhow, congrats on the strong runs.
