Corvette C7

[Eunos_Cosmo]

Nonetheless, it shouldn't be slower than a C6 ZR-1. I had forgotten the new car is 3550lbs. That is substantially more than the old Z. Shame. Just image a 2800lbs C7 Z06 with a 550hp LS7....

 

[YSSMAN]

Slightly slower is fine with me given the massive gains that have been added to the car when it comes to overall stability and grip. But, man oh man, I definitely wanted a street version of the C7.R's 5.5L V8 for the Z06. Would have been interesting to see something like that going head-to-head with Ford's flat-plane unit, or the whole mess of European units of relatively the same size.

I agree, as @YSSMAN said they have made plenty of gains in stability, balance and aero as well as mechanical grip due to the Le Mans car. Furthermore, with the new talk of how it's beating halo cars that are 10x the cost around certain tracks, as well as the car looking planted quite well in the track videos shown...it should be plenty faster than the old cars. The problem is how much, because the idea of a guy who spent 120k on a ZR1 two years ago, that could have waited and got a Z06 C7 that is a second faster for 85k seems a bit harsh.

On another note this is pretty impressive
"The LT4 has already proven to be a very capable engine, since the tuner has achieved a hefty output bump with less-than-serious mods. To be more specific, the V8 was taken to 660 RWHP and 663 RWTQ (899 Nm) using only a cold air intake, a smaller upper pulley and, of course, an ECU remap."

Motortrend said that GM engineers were forced to use a supercharged engine because of emissions reasons.

I honestly wonder if a "LT7" 7.0L NA V8 is even on the table. It just might not be feasible for modern emissions standards. GM is still able to do plenty with their favored 6.2L layout.

In regards to the C6 vs C7, I think that a modified C6 Z06 would probably turn in faster laps than the C7 Z06, but the C6 has a reputation for being a widow maker without the help of extra horsepower. Part of the charm of the new Z06 is that it's not as unforgiving as a dominatrix on her period.

"Pretty impressive" is quite the understatement, isn't it?

Makes you wonder just how much oomph someone's going to get out of some more serious mods.

While pullies usually refer to underdrive pullies, a smaller upper pulley on a supercharged engine makes a tremendous difference. 2003/2004 Cobras made around 360whp stock and upwards 460whp with a pulley and tune. Basically, for those who don't know, a smaller upper pulley changes the effective gearing of the supercharger so it spins faster and makes more boost. So while the LT4 makes 9.5lbs of boost stock it might make 15+ with a pulley. Big difference. So I think that quote is slightly misleading.

 

[rosckolove]

It's not misleading at all. The heads don't come off the block doesn't come out there is no machining to be done no cutting the fire wall or mounting intercoolers/turbos/piping. It's less than serious, anyone could do it, the part(s) (do you need a belt with less teeth?) isn't even that expensive. I agree that it is quite an effective upgrade. Perhaps the best you can get for the money. But it's nothing compared to changing pistons/cams/rears.

 

[McLaren]

Not sure if this would have anything to do with it, but what about the transmission choice?

Car and Driver seemed to indicate that the models equipped with the manual were a good bit slower:



Seems to be an ongoing pattern with all of the supercharged models. The automatics are almost always faster.

With the length that Viper gained, the auto isn't going to make the difference; the manual should be holding its own to start with. Owners are worried the A8s may suffer even more from the ECU stepping in.

Difficult and expensive? No, but there's more to it than that.

Upping boost will change the lifespan of the engine and the wear components, which really can't be said about your standard intake, ECU, exhaust. The article makes it sounds like a pulley change is comparable to the "Stage 1" mods that plenty of people do when it's really not.

Exactly. It might be easy, but it doesn't mean its "minor."

I wish somebody offered retrofit installations to put the C7 interior (with functioning digital gauges) into the C6 platform. Imagine a heads, cam, and intake C6 Z06 with a C7 interior. Mmmmmmm.....For those that don't know the LS7 can make some serious power naturally aspirated:

Stock vs stock, a Viper TA pulls on a Z06.


Very surprised, even more so that the out-going ZR1 started a slow pull. The real shocker is the Corvette community acknowledging this as possibly even more evidence that the cars have a serious heat soak issue. A few owners are complaining about a loss of power after 3-4 runs, & a shop confirmed that the ECU is extremely conservative & pulls timing for almost any situation. Currently awaiting to see how owners do on the road courses after a couple laps.

I love this video plus 1 for the viper ha.

For $5,000, you can hand build your Z06's engine. Included in the cost is all hotel, meal, airline and various other fees and you'll get a plaque certifying your engine with your name, as well as complete professional photographs of you actually putting it together.

Welp, that's one of making your car personal. Helps if you want to brag in front of your friends.

Joke aside, interesting move, the photos are a nice touch.

They've been doing the engine building program since the the release of the LS7, and then the LS9 as well.

It doesn't surprised me that it was continued.

Uh, hello; I figured that since this thread hasn't been active in a while; I thought that I would bring it back to life with this. A limited production Z06 Corvette.

[Cale]

Should be more differentiated IMO

 

[RandomCarGuy17]

I agree actually, it doesn't really look any different from a normal Z06. I don't think I would be able to tell one apart from a normal one without looking at the badge.

 

[catamount39]

How about actually having the Corvette Racing livery on the car? Maybe even the actual rear wing...and some more of the C7.R bodywork.

 

[Leonidae@MFT]

Did they fix the alignment and overheating issues?

 

[McLaren]

Basically a fully loaded Z with some extra exclusive eye candy.

Ah yes, I'm glad to see they kept that brick wall of a rear spoiler instead of using a wing that will create more downforce and stability with much less drag and therefore not harm the car's high-speed acceleration and top speed so dramatically. There is a reason the NISMO GT-R outperformed this car on a fast track and it isn't because the Nissan is several hundred pounds heavier. Even the Viper TA 2.0 eschewed its ducktail for a proper wing.

Totally agreed...they should have replaced it with the C7.R's wing or even something like a mini-GT4 like wing.

To waste the C7.R moniker I'm disappointed this is nothing but a sticker package. I was hoping for a lighter, stripped down, even more track oriented car (and one that has better cooling for track use). They had a great opportunity but missed it. Here's in hoping for a "Z06.R" version that is a raw, lightweight and even more track built car.

And I agree with others, the rear spoiler causes way too much drag, it's a giant wall. The stage 3 aero causes it to fall flat on its face after about 130+mph.

Here's a new record 1/4 mile pass. A8 transmission, completely bone stock, stock tires.
10.42@132.6 mph,
1.5 60'
