Z06 vs Viper T/A

[shank0668]

I do kind of agree with some of the comments, z06 does need a driver mod.

Here's a link to the discussion and video talking about the test.

Further reading into the comments that were posted in the corvette forum, most of the hardcore members agree that these are the growing pains of a first year intro of a corvette model with a new engine. Some of the comments refer to issues that are in the ecm designed by GM to ensure that the warranty is intact for MOST of the customers that purchase this vehicle. Anyone wishing to pursue the full limits of the car will do so at their own risk. Vengeance Racing will be revealing their findings in the coming week(s) for those that wish to pursue those limits.

The Z06 is more car than the majority of people out there can handle. GM needs to serve the needs of their customers as well as keeping them safe as much as possible.

maybe I'm not forgiving enough, but there should be no growing pains on an American car that cost's $80k+. And one should not be overheating after 5 laps. Did the Viper overheat? Then again, at nearly $30k less than the Viper TA, im sure you could take half of that and make the NEW Z06 better and faster than a NEW Viper. but who knows.

The Viper was 105k so you are a little off with the 30K, think that the Vette was up there in price as well.

Yes, this was a $105K Viper vs $95K Corvette

Stage 1 z06 manual comes in under 80k

HUGE LET DOWN!!!! What's next a 3800lb 6th gen camaro? How can Chevy let something like this happen to the most sought after car they build?

Anyone ever see a ZL1 running in the 13's or not exceeding 110mph at the drag strip? I think it might be the same problem with the LT4. It's probably heat soaking easily and getting really high IAT's thus killing tons of power. I seriously don't think that's a factory tune issue. If the IAT's are soaring a tune isn't going to fix that and if you go soft on the IAT tables then you could be looking at a hurt engine unless you use some sort of race fuel or E85.

Very solid point...

That is very difficult to do while meeting emissions, which is why so few engines accomplish it.

Larger production numbers don't help an engine meet emissions requirements. If anything, a low volume car has an advantage because I think there are exemptions available for ultra-low volume cars. But both the Z06 and the GT350 will be grossly exceeding the production cap (I think its less than 30 cars over the entire production run) so that exemption doesn't factor in.

I'm sad Ford will have his 'LS7' equivalent while GM wont have anything like it anymore. Ford will get my money, maybe..unless I chose a stock LT1 SS with a ****ing cam!! That is going to be a badass car for the money!

I'm a N/A fan, too bad they have to go the FI route now. I mean its the 1st year, they are going to fix the issue or let the customers do it (speed shop). Its still a bargain with no option, but its weird that a N/A car with less HP and same weight kill it.

Yeah old ZR1 kicked some serious ass at the time.

The LS7 remains the ultimate performance car for the money IMO.

this is exactly why im sad they went FI with the Z06. I mean I get it, its easier to meet emissions standards with it. but damn...heat soak, high oil temps...idk

[SpeedIsLife]

Watching all the Corvette apologists coming out in droves to defend the new Z06 has been fairly entertaining.

I do agree that the excuse of "it's a new car, it's going to have teething problems" is utterly stupid. A C7 Z06 is at minimum a nearly $80,000 car, and with all the bells and whistles it's over $100,000. It's not exotic, it shouldn't have "teething problems", if that is GM's excuse then it's a pretty sorry attempt at covering up a major screw up.

The heat issues is surprising given the level of experience GM already had with FI, testing that was done to validate the LT4 and the intention of the Z06 as a track weapon. The minute a smaller displacement, higher revving blower was proposed, the technical issues with cooling were known.

Something doesn't add up. GM surely knew exactly how this car would perform when it hit the track. If it can't be cooled, is a bigger blower and power-bulge hood in the future? I'm waiting to see more of this story unfold
