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

Jordo!

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

Feh.

One of our car club members is a GM at our local chevy dealer. He says that since all this info has come out people are cancelling their order on the Z06. He himself was going to trade in his 711hp 2008 Z06 but opted to just supercharge his current 2015 C7. Oh well, guess we'll see how chevy responds to all this

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?

PharmDZ

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.

MightyBobo

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.

MJB

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

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

cossie1600

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!!!
