Which GT3 engine had issues outside of the 991.1?

 

The C6 Z06's 7 liter had issues with exhaust values wearing and causing possible catastrophic damage. However, the more pedestrian LS and LT engines have been very reliable, historically.

 

997 - coolant lines
991.1 - engine fire recall
991.1 - finger follower fiasco
991.2 - leaky oil tank

Not dissing the GT3 - I’ve owned them all, have one now and have an order down for 992. Just answering your question.

 

Also 991.2 have lash adjusters dropping as well as wear on the block issues. These were reported sporadically in 991 forum. I know some people dont like to talk about it because they dont want the commodity to take a resale hit but no engine is perfect.

 

I really can’t see the Multimatic shocks being used on the Z07 version due to the very non-compliant ride on the street. GM knows that many Z07’s are sold on looks alone by owners who will never track them; GM is not going to overlook that demographic by ‘ruining’ the ride. Both versions will come with the Magnetorheologic shocks, although the Z07 will have suspension components chosen for better handling.

 

I could still see some option including the spool shocks, if it helps them set a blistering Ring time (seem to be a priority)

 

really seems like the ring time is going to come down to getting a stickier than a cup r that they are able to sell with the car.

 

With nearly 700hp and CupR, should still be pretty fast

 

Companies make surprising decisions. Consider the current RS6 wagon which the option of a very performance-focused minimally adjustable conventional spring setup, vs. The electronic air suspension option which basically everyone chooses. It's very strange to even offer the hardcore performance version on a heavy cruiser like this, but for some reason they do.

Z06 has a strong track-bias, it's the hard core version, probably won't be chosen over other more powerful ones like zr1 or hybrid or electric. I see it as very probably that z07 hardcore package of a track car gets the multimatic spool shocks. They were already on the track focused camaro and are acknowledged to be the best.

 

Why not when they already use them on a Camaro?

 

I don't know of any that blew, literally, for any reason other than operator error. I was using it as a general term referencing the problems Ford had with their Flat plane crank engine in the Mustang. The difference I see is Chevy os out testing it right now in endurance racing, which Ford did not do. SO there must be something that they have that the Ford engine did not.

 

Elite-ism is quite strong with this forum. No one blinks at a 991.1 GT3 being on it’s 3rd or 4th engine and yet still people talk about how the Z06 won’t hold up to track use.

I am a Porsche owner and love it, but a dose of honesty would be helpful.

 

I would definitely option the spool shocks if available, and I’d only use the Z06 for occasional HPDE’s, but mostly on the street. I don’t care much about comfort in cars like these, even on the street.

 

3rd or 4th engine? Speaking of honesty. How many GT3s are on their 3rd or 4th engine for some reason Porsche is responsible for?

 

I’m aware of one C8 engine blowing up at VIR this year.
