GT500 vs...

[mustangletback]

Damn, that is disheartening.

They didn't specifically say it was a cooling issue although, it had to be pulling power for a reason.

It's true the Corvette doesn't enjoy direct airflow as much as the CTS-V and it would certainly be the reason an LT4 would run hotter... but to just kill power for no reason is something strange.

alot of the motors blowing up with the z06 and stingray were not even being tested on the track.remember the blown motor with 6 miles on it?i think there were a couple that had less than 900 miles on it.i think the problem is the motor itself.:lol:

It must be an ECU issue but related to the VVT and additional supercharger. Only the Auto LT1 seems to have obvious cooling issues, I'm starting to think the 3 radiator system in the '16 Camaro was a preventive measure for the Auto equipped LT1 cars. If there is a future 1LE type Camaro, limiting it to manual only and using a larger, single radiator may be a good way of keeping weight down. Of course it would be mitigated by rotor and suspension.

However, an LT4 equipped car could be either-or, doesn't matter if the engine is killing itself like this... Once they examine some of these break downs, I hope there is a conventional fix and not some deep rooted design flaw.

Some are hinting that the Z28 beet the GT350. What have you heard/read?

well pill,i have heard from many that it is a design flaw.i dont know if it is or is not.what is known is the car cant be ran for long periods of time,without some kind of issue.

No, the Z06 laid down a better lap time than the GT350R at Road and Tracks event. Both the GT350R and Z06's footprint are as close to optimal as any Mustang, Corvette or any pony car or American car EVER. Maybe some U.S. Sports cars have come close but never these two.

The GT350R is about as fast as a C6 Z06/Z07...

The GT350TP is about as fast as the z28 and C7 Z51...

The GT350 looks like it will be approved in some SCCA/NASA Classes. It's faster than a Boss 302 Laguna Seca and '13-'14 GT500 at the tracks it tested at.

Then there is an issue with the ECU software in conjunction with the VVT support and hosting FI. It very well could be a preventive measure intervening on the LT4 due to airflow restriction and heat.

As thePill said many times before, 24 Hour, Wide Open Throttle test are great, but ambient track temperatures can be a killer for a bottom feeder. In this case, it's not giving the engine an opportunity to hurt itself and its getting some intense heat wave patterns from the track.

Design flaw? Yes... but is it only at the ECU/Software level? That could be an easier fix... The CTS-V has great airflow AND, the LT4 is t turn't up to 650/650. The CTS-V and LT4 Camaro's will need to be tuned down some so the Z06 can come down some.

Just my crazy opinion...


...think about it though... the Z06 is pushing its LT4 a little more than the CTS-V... It could be as sime as turning it down some.

true,not only that the z06 may have more than 650hp from the factory,and its tapped out at its max,that could explain some issues as well.

 

[mustang_guy]

The c7 z06 most definitely does not have more then 650hp. Join the vette boards. Its hilarious how the viper ta hands it its ass stock and full bolt on vs full bolt on. Fing hilarious

the reason i said that is because they might have been conservative with the numbers,it might have had 25hp more or less give or take.the GT500 had more than it was rated at.

Yes the 13-14 gt500 was a bit under rated. The c7 z06 is definitely not under rated.

Yes the 13-14 gt50p was a bit under rated. The c7 z06 is definitely not under rated.

ok,its not that im a chevy fan,i was just trying to see why the motors are junk.:lol:
:cheers:

 

[mustang_guy]

It makea no difference either way if you were or weren't. Vettes have gone down hill in the reliability department since the c6. C5s were much better in that department. Shame.

well they have gone down because they rush things just to hurry and get it out.Garbage Motors has been a Gigantic Mistake for a long time.PeterMJ's Corvette C7 Stingray and Z06 Exposed

It's not that the engines are under or over rated, I just believe supercharged engines have a less consistent/predictable output... when it comes to the official testing standard. I don't think it is anything intentional... this appears to be a common thing among supercharged engines.

the guy on that site has some good thoughts on why there is an issue.have you been over there and read it yet.?:lol:PeterMJ's Corvette C7 Stingray and Z06 Exposed
