I have a very fond memory in a C6Z that pinned me to the seat with each shift wrenching your neck and the rear end squatted and smeared down the on ramp. I've also been in a Tesla P85D that pulled your face back like Jeremy Clarkson in the Ariel Atom, but didn't have much emotion involved and overall was kind of boring. Do you think the C8 will provide that 'oh $hit' type of experience of the C6Z or will it be more subdued and smoothed out like the Tesla? Or somewhere in between?

I think the C6 Z06 will feel far more "ragged" and shocking. When the OP talks about coming down an on ramp, we are talking about from a roll vs. a standing start. The only reason the C8 is so quick 0-60 is the rear weight bias and traction - not pure power or power to weight ratio. I had a C6 Z06 and and C7 Z51 - and the Z06 felt much quicker to me. I used to always scare friends and family by dropping my Z06 into second, revving and dumping the clutch at 60 mph and fish tailing down a country road near my house with the engine revving 7k rpm. The dual clutch in the C8 alone will stop those antics. My C7 was a far better car - and I'm sure the C8 is is far better than the C7 - but the ole Z06 was tough to beat in terms of thrill factor! Weight is part of the equation too . . .

The top 37 runs in the C6Z06 fast list are under 12 seconds, bone stock with stock tires. I don't think my run is on there. 11.6 at mid 120s first time running it before drag radials. 0-60 were mid 3s in most cases. Maybe you are thinking of the C5Z?

Something they haven't done before. The C7 Z06 by Chevy was a 1ft rollout 2.95 same with ZR1. In the magazines back when they came out the C7s were always 3.0 to 3.3 ish. We will know the truth when the dragy, vbox etc times are published. Dragtimes will get his hands on it and I will believe what he posts because He is a very good driver extracts most out of the cars he runs (look him up on youtube) Will post the Actual times on the screen from the devices. With and WITHOUT the 1ft rollout which can account for .3 .4 seconds. Chevy did a great job on promotion. Time has come for this car to be put against the icons and youtube will help settle the debate very very soon.

GM's factory ratings on both cars: C8: 0-60 = 2.9 secs, 1/4 mile 11.2 @122 C6 Z06: 0-60 = 3.5 secs, 1/4 mile = 11.7 @ 125 From the dig, the C8 will kill the Z06 but as speed increases the Z06 will start to pull on the C8. This is mostly due to the Z06's lesser weight (31XX lbs) and having to feather the throttle on launch. I don't think the 10 hp has as much to do with it. Drag radials will "probably" make a much less difference in the C8 than the did in the Z06. Ranger ran a 10.8 @ 128 with a bone stock C6 Z06. Arguably, he's one of the best 1/4 mile racers out there though. Another benefit of the C8 is that you won't have to worry about the proverbial "valve drop" issue that grenaded your engine leaving you with a $20K =/- bill to digest. GM never fixed this issue in the Z06's 8 years of production. This happened as soon as 2500 miles on the clock. Jake, for the most part we can thank a Canadian supplier/machine shop for this, as they provided extremely crappy CNC jobs on the factory heads. They're also to company that initially sent C7 tranny/differential units to GM without filling them with with fluid, as GMs contract with them specified. This resulted in quite a few drivetrain casualties to. On the street the C8 will be the beast of the two, that is, unless you want to dip into 100 mph+ speeds and risk life and limb, not to mention your privilege to drive. .

Yes, stuff like that can be entertaining. I've had lots of fun driving sideways in my supercharged C5, and also in my C7 Z06. This may still be possible in the C8 by depressing both paddles to put the transmission into "neutral", and then releasing them Last edited by Warp Factor; Feb 14, 2020 at 10:37 AM.

That pull to 7,000 is just awesome. The C6Z is 400 lbs lighter than a C8. C8 will launch hard out of the hole and probably maintain the lead in a 1/4 mile drag race, but a highway pull to 150 or so the C6Z is a monster. There are videos back in the day of them pulling Ford GTs with relative ease. I love the C8 and am excited to get one, but GM has made these cars very heavy since the C5/6 days.

On the street the C8 will be the beast of the two, that is, unless you want to dip into 100 mph+ speeds and risk life and limb, not to mention your privilege to drive. . A late friend of mine built my LS7 engine, losing all the titanium bits like rods and valves. No machining issues on these heads, just very poor materials. The major problem is dumb *** drivers who don't know how to shift, especially down. Use a C5R timing chain. Get rid of those useless titanium exhaust valves which is the root of the LS7 drop valve problems. Use Ferrea F-2042P-8 SS 1.614 exhaust valves for N/A only. Only weighs 18 grams more than stock valves. Lash caps very important. The real fix is to install powdered manganese bronzanium 90 guides which extend .250' further into the port and have excellent endurance. Jessel adjustable rockers. $200 each.The mass is reduced between fulcrum and tip. The mounting girdle distributes the load reliably over the head casting vs. the junk stock rockers. Keep stock ratio of 1.8:1 to retain max lift at 0.6. Keep stock intake valves but polish and coat. Del West makes them. Titanium has low modulus causing stretch at high rpm and separating the valve from it's stem resulting in mass destruction if you miss a gear or downshift like an idiot. The valve can actually come into contact with the piston before separation These valves and the rods don't even like the 7000 rpm the stock engine revs to. Keep titanium out of your engine if you want long life for track days. Just keep LS engines below 6500 rpm. The chromium nitride coating required for titanium valves, wears thru resulting in increased guide wear because titanium hates everything but titanium so it goes to work on the bronze guide. The off plane angle of 12' is far less than the LS3's and LT's 15' but still has high side loads, hence extended guides. The very expensive factory titanium rods are good for no more than 7000 rpm and 500 HP limit. Callies’ Ultra connecting rods are forged from a proprietary 4340 Timken steel alloy. Made in the USA. The Ultra rods have gussets around the cap screws to help fortify the big end of the rod. Cap screws are rated at 260,000 psi. Additionally, the Ultra rods’ I-beam design reduces mass over a comparable H-beam. My rev limiter is set @ 6500 RPM 590 HP at the wheels. Result, bullitt proof long life engine.

Driving is becoming an easier, safer, smoother experience. Less chance for the rear end to kick out, less tire spin, more consistency. The C8 has reported to have one of the smoothest driving experiences yet. That visceral experience, at least in the base models will no longer be there. Reply 0 0

Sure... because you just mash the gas and point the steering wheel straight in the new car... all the nannies will keep you in line for the most part. The C6Z06 will be the faster car other than from a dig. Now on the road course it will be very interesting. The C6Zs tires are crap compared to the C7 Michelins. When they were testing the C7 they put the baby C7 245/285s on a C6Z and went faster than the larger GoodYear F1s. Most well driven trackday C6Zs will run low 2s at VIR. Pobst's current best in the C8Z51 is a 2:00.9. So... equal tires I'm going to give the edge to the C8 because of the ability to power off corners and stability under braking. The C6Z will make up some time on the straights, but probably not enough to make up for the C8's launch off the corners. One huge difference... I can legitimately track the car hard in the stock seats (not even the comp seats) with a C7 and C8. The C6Z seats are hot garbage. Can't drive the car hard w/o a race seat.

I own a C6Z 2006 barely modified with just cold air induction and a tune. It put down 470 rwhp on a mustang dyno and I’ve owned it for 110,000 miles. I’ve driven it to 11.6 @ 124mph in the 1/4 mile on regular Michelin (non-runflat) street tires). I have on rare occasion been a passenger in my own car. I went for a ride in a C8 non-z51 car in early January. The road conditions were not ideal, high 30’s temp and damp. The car managed traction far better than my 2006 can and still rocketed away to a very satisfying degree. IMHO the C8 base is every bit as good as the C6Z. I passed on C7 base and C7 GS due to obvious and very noticeable lack of power compared to my C6Z. I passed on C7Z because I don’t want forced induction. I thought I needed to hold out for a C8Z before, but the experience sold me on getting a C8 Z51 and then upgrading later. Last edited by mikey; Feb 15, 2020 at 12:19 AM.
