Genuine question. Memes aside. How did General Motors manage

They lost sight of what made the C5 Z06 such a huge hit, and instead, chased horsepower numbers.

>>15780894
By not making a GTR

didn't put an ecoboost in it

They gave it too much horsepower, and not enough downforce/grip. Every time you come out of a corner, you have to fight the rear end to not fly out.

About the cooling, they just tried too hard to keep the price down and didn't compensate the cooling system enough. Supercharging was also a mistake, z06 should be NA, ZR1 should be supercharged.

>>15780984
Exactly. They got too ambitious with everything. 3 packages and all those expensive add ons. The Z06 should be about no frills trackability and balance. Cut the electronic BS in the cockpit, use the savings for a better track setup than the base C7. It might have needed more power than the base, but not 650HP

No you idiots, no. Literally all it needs is a cat relocate and a heatshield for the oil cooler.

>>15781414
What? I never said how the cooling should be fixed, just that they didn't do as much as they should've in terms of cooling

>>15782261
The cooling is being addressed in the 2017 model year.

>>15780894
FYI it should be noted that, the car featured in the article written by motortrend had been used by car and driver for its lightning lap a week before and GM neglected to change the brakes out after that run.

>>15780939
This

>>15782261
That has nothing to do with cooling. It's about preventing it from getting too hot where it needs more cooling in the first place. The cat is right next to the oil cooler with no heatshield. Move the cat further back and put a heatshield between the exhaust and the oil cooler and engine doesn't shit itself.

Undersized Supercharger that acts as a heat pump
Pathetic factory cooling system
Cheap ass Chinese metals used in engine
Cutting corners in every aspect of build quality to stay cheap (recalled over 12 times in first three months of release)
Pushrods

This doesn't solve the problem, it will still overheat during track duties. An aftermarket company did a test and they only dropped an average of 20f a lap

>>15780894
I lost you at "Genuine question, Memes aside.".

>>15784325
Got a link? Because the coolant temps were never the problem, the problem was that the oil was reaching 300 degrees. I've seen at least one dude that claiming that he did 10 laps at Road America and kept his oil under 250 with just an aluminum heat shield, no cat relocate.

And 250 is perfectly acceptable for oil temps in a track car.

>>15780894
From a technical basis, they rushed it to market 6 months to a year too early.

This caused 3 problems.

First, their fleet guys were not all trained in maintaining and setting up this car for the buff books. In the Motor Trend Head 2 Head Challenge, the car had an off the week prior and been fixed, but the people who aligned it didn't even know it had rear caster angle adjustment in the suspension, and so they never checked it. Then at Best Driver's Car, they a got a car that was fresh from being driven into a wall by Car and Driver, and the coolant lines for the intercooler were never bled, so it couldn't keep it's charge temps in line, and responded by pulling timing and venting all the boost. So those are two fuckups with regard to training their dudes that gave them huge amounts of egg on their face.

Second, they rushed the traction control software. It's nowhere near optimized. This has sorta been fixed since, but they simply needed more development days before they went live, and shipped with a half baked product. Best evidence is the "rough track" setting that debuted after the H2H comparo.

Third, they don't have adequate oil cooling or heat shielding around their exhaust system where it runs near the lubrication system. This is kind of endemic to all early C7s, and likely the cause of their early engine failures. They just didn't do enough testing on their final packaging setup, which causes the engine to scavenge heat from the exhaust and cats, using the motor oil. Great for heavy equipment in Siberia, not so good for sportscars.

Philosophically, the biggest problem is that they forgot that what made the Z06 awesome was it's hardcore dedication to the spirit of the GT racers, even if the race cars went from 7 liters to 5.5 half way through the C6 Z06's run, that was the heritage of the package.

Instead we got a ZR1 wearing the Z06 badge.

Shoulda had a 9000 RPM 5.5 liter V8 and a Z28 style "everything delete".

>>15785673
This guy gets it. Worded it better than me. I remember the C5 Z06 used the C5R block and the C6 Z06 was 7 liters like the C6R before the FIA/ACO hammered away at GT1. The second they announced the Z06 was going to have 3 packages and all of them would be supercharged, I lost interest.

>>15780984
Not enough grip is true, the leaf suspension is a good concept in theory, but it lacks the Vipers adjustability.

Z06 should be supercharged, ZR1 should be twinturbo.

>>15785590
Oil starts to break down very quickly over 220.

Most people who buy Corvettes are retired and only use it to cruise on weekends, for which the Corvette is perfectly suited. Most people who take their cars to track-days shell out twice as much money for a 911 because they do nothing to prep a car beyond the tires, and (most) 911s are over-built and can take that shit every week.

>>15785590
im talking oil temps, largest drop in temperature recorded in their tests was 40f

>driving the shit out of a vehicle in the desert
>complaining about overheating issues

I'd like to see the fat fucks here run the track and not overheat.

Shitloads of boats run LS engines at full power all day and have zero issues.

>>15787397

Pretty much this. Let's face it. It may be marketed as a "track car" but GM and most of it's customers know that it really isn't.

>>15792641
Yea

>>15784325
Every production car eventually overheats in track duty. Be it the brakes, the oil, tyres or whatever. These cars are made primarily for the road, not the track.

>>15791118
This is why manufacturers take their cars out to Desert Valley and the Northern Territory and shit like that to torture test their cars before they are released.
So they can be driven like fuck out in the desert without overheating

>>15781010
So Z06 should have been the Grand Sport

>>15795119
Yea, pretty much
