Durability
 

Based on what we have read and experienced....how do you think the car and all it's parts will hold up over a little time?

10k miles and everything holding up except for suede shift nob and tires so far

The ZL1 in my honest opinion is purposefully built to be modified and powered well beyond what has been delivered from the factory. All the underpinnings, MR suspension, transmission, rear axle housing, LSA, etc...etc..are the groundwork for a car to be maximized by the performance market to develope it to it's true potential. That is if the buyer chooses to do so. Solid as a rock the car is. No doubt.

:word:

Are hyperuteitic pistons and powder metal rods your ideal of solid as a rock?

That was one of my first thoughts too, but there are a lot of CTSV engines that are up to 700hp long term without failure.

We have professional engine shop sponsors here who have posted their build info. One highly notable builder has documented that the factory short block is good for 700 HP. That's solid as a rock my friend....and I'd be plenty good to go with that output for my ride.

Given that the warranty carries over to track days, GM must feel pretty good about what they have built. I am personally putting out about 770 crank HP and so far, no troubles at all. Took the car on a 800 mile round trip journey and averaged 20 mpg on the highway at 70-75.

I just worry about tunes , fuel quality, and detonation. What happens the first time you go lean, or get too aggressive with the timing? With those internals there is not much room for error. I understand under perfect conditions 700 HP might be ok but under real world conditions I'm not so sure. If Im trying to sell my preformance products I might possibly push the hp envlope. People will, and time will tell.

I hope Camzl1 recent steering failure is not a sign of future things to come. We still have no answers to what the QC hold was before they would release the 12's

I would be a little concerned too Rubble....... I have had a ton of New and used cars but never any serious safety issues like what happened to Cam.... Frigthening...

I wonder how many miles the average 700+ HP ZL1 will last mileage wise

My next car will hit low tens I am just not sure what I can expect longevity wise comparably

I would guess the people that mod their cars to get 700+ HP etc, probably won't be putting as many miles on their cars as people who keep it stock.

On the other hand, depending on their driving habits, the miles they do put on the car may be a bit harder on the engine than normal miles.

I had my warranty issue very early my car now has 14600kms and I have been beating the crap out of it. has 601 rwhp and I need 4 tires and it drives awesome and feels like new still
