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).
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.

PRE-Z06

I hear ya on it making more torque and having shorter gearing, but until a manual C7 with bolt-ons runs a 10sec 1/4 or traps 125+mph I'll have a hard time believing it's actually quicker in similar conditions. The C6Z still has better average power and power to weight ratio which is what wins a race, not a peak dyno number. Though I imagine it could be close enough of a drivers race on the street that a good driver in a bolt-on C7 would beat a bad driver in a stock C6Z, especially if the latter was a heavier griver, had a full tank of gas and a passenger.

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.

Omg!!! Finally!!! Someone gets it I've been arguing this point since I joined this forum. I owned a C6 Z-06 and a C7 wouldn't hold it a candle any way shape or form as far as putting the power to the ground and all out acceleration.
