new Z06....cuts power after hard runs...

MightyBobo · 12-12-2014, 08:44 PM

How many people in this thread complaining about it not being "track capable" have ever actually tracked? Just curious...

Or have an oil cooler on their own car realizing that a couple laps in the Z will lead to limp mode, which is worse than "cutting power"? Hah can't knock this car for a power loss if we can't even do a track day without limping back to the pit without an oil cooler! A lot of cars have some sort of inherent weak point that needs to be addressed for consistent, reliable track use.

Yeeeeup. Bench racers bitch about this, and that's about it. There are almost no true, 100% track capable cars from the factory. Everything has some thing I'd want to change. Z/28 is a good example: amazing car....with horrendously expensive brakes, that I'd immediately swap over to traditional rotors/pads.

I wonder what the tradeoff would be with the brakes though? Are they THAT amazing that you wouldn't have to worry about replacing/warping them as often as traditional brakes? I can see what you mean though... if I had to replace carbon ceramics I'd cry.

With a CAI, pulley and tune this Z06 made 660whp/663wtq. Pretty dang impressive.

Go ask the Porsche guys what happen to their expensive carbon brakes after one track day, they will tell you it was an expensive $4000 mistake. After one day!!!

The trade-off is you save a ton of money, and for people who really race, that is (almost) all that matters lol.

They did that on purpose for emissions and longevity purposes but GM says you can take it to an aftermarket tuner to extract more power at the expense of voiding the warranty. No big deal

Considering one test car blew a motor almost right away, probably a necessary de-tuning by Chevy.

Feh.

While there is a slight air of disappointment. Really, power is cut from 650hp to what? Maybe 550hp? I'm just guessing but the car is fast Azz for the price.

I wouldn't buy it yet as a first year model BUT power cutting isn't convincing me to dismiss it yet. And I wanna see it against a GT-R Nismo

From what I gathered in the Vette forums, a couple owners had their Z06 dynoed, and after 3 or 4 pulls were already losing between 20-30whp.

Here is what Vengeance Racing had to say-
"With the OE calibration we did experience the same thing... The timing tables are EXTREMELY conservative and the ECU will pull timing for almost any situation. I am waiting for owners to complain about "tip in" as the ECU pulls a massive amount of timing when slightly touching the gas pedal.

All that being said, MOST of the loss of power can be addressed in the ECU.. IAT2 temps are actually quite impressive, even after multiple pulls on the chassis dyno. We will get on the highway in the next couple of days and make some back to back "multi gear" runs for comparison sake."

I'm sure a few will get blown up by Tuners, then the owners will want GM to warranty them.......then we will get a bitchfest on the Vette forums.

Install an oil cooler?

Agreed, but how long can it do that....if the tuner gets it too lean or heat soak happens?

My only issue was seeing one run the 1/4 mile and only trapped 120 mph. That's considerably slower than the previous c6z06 which was in the mid to high 120s
