All those mods should get me to that 458 level but with way more torque.
Plus the short Z51 gearing should make for a quicker car.

I have or had both cars, and yes, bolt-ons (tune, headers, CAI, ported parts) should get you to C6Z06 HP powers. Just a tune and air filter got me 440 (c7) on a dyno i've used for years. And with more torque already than my stock Z. (that car put down 458 stock, same dyno).

I would argue that exit speed on the corners will clearly be in the C7's camp over a C6 Z06, and the ability to put down the torque earlier. Exit speed is perhaps one of the most important things on a road course. I am doing stage one bolt on's CAI, Headers, Tune and will be running with Z06's so it will be interesting to see how it stacks up. The E dif is really good at putting down the power.

I don't know what you mean with your reply, sir. I hope this is a debate not an argument. If you are just talking about dyno numbers....then the numbers could be close. But when you put these two cars on the ground with the C7 bolt on.....not going to happen against the C6 Z06. The C6Z06 is considerably faster than the C7....hands down. 125 mph trap speed through the 1/4 mile for the Z06 and about 200 mph top speed. By the way, nice numbers. I know of a friend with similar bolt ons which resulted to 442/450 automatic.
