Ideally I would like to see 6lbs per HP but that is probably on the aggressive side.

hig4s

Exactly!

jackhall99

I hope 6 pounds/HP was a typo! Otherwise aggressive is an understatement amigo.

The Z06 is currently at 6.33, give or take a tad. For that model to hit your number, it needs 533 HP (very probable), a weight loss of 169 pounds (mission improbable), or a combination of the two. So the Z06; maybe.

The base model would need a 100 HP increase (ain't gonna happen) or an impossible diet along with a huge bump in power.

We'll see in six months.

hig4s

isn't the current LS3 model numbers from 7.1 to 7.3?

I could see a C7 being 6.8 or 6.9.

jackhall99

7.39 with no options, again give or take a tick.

0WildVettes

Wasn't a typo. 3000 lbs and 500 hp in a perfect world.

jackhall99

I know the numbers, but 6 lb/HP for the base model?? No way, IMHO. We'll find out soon though.

CORVETTEZL1001

Chevrolet is aware of whats going on in the marketplace they will design the C7 accordingly.

0WildVettes

The C5Z had a curb weight of 3118 lbs and 405 HP.

I really don't see a weight loss of 100 lbs and 100 more HP in a car that is newer by 12 years being a HUGE stretch. It is probably a stretch, but you never know. One can still hope.

My current C5Z is sitting at 6.6 right now and the engine is stock, so it is definitely possible with some new techniques and some DI love.

Ok, to make you and the other members that disagree with the weights posted by motortrend regarding the centennial zo6 and zr1, lets use the 154lbs difference that your harping on. That still gives the zo6 a 6.4lbs per horsepower ratio compared to the zr1's 5.3 lbs per horsepower. And the zo6 is still faster on smaller tracks. This is my point, a car that is balanced all the way around is far better than throwing a bunch of horsepower into a car and expect it to be fast. We dont need zr1 horsepower in the base c7 for it to be a fun fast car, just better design. I hope this puts out the fire! Cheers[/QUOTE]

I didn't raise issue with the other parts of your posting, just the incorrect weight difference between the Z06 and the ZR1. There is one thing about the Internet, someone makes an incorrect post, and unless it is pointed out in a correction post, the incorrect crap becomes "Internet facts" and people, years from now, will think the 95 lb weight difference you quoted is indeed fact.

Here is what the centennial edition consists of on the Z06 and the ZL1.

ZLC NEW! Chevrolet Centennial Special Edition, includes exterior
color (58U) Carbon Flash Metallic and Chevrolet Centennial
Black wheels
1{Z06} - Requires (195) Ebony interior, (38S) Red custom leather stitch,
(RUR) Chevrolet Centennial Black with Red stripe cup style wheels
and (F55) Magnetic Selective Ride Control or (Z07) Z06 Ultimate
Performance Package. (J6F) Red calipers required when (Z07) Z06
Ultimate Performance Package is ordered.
2{ZR1}- Requires (J6F) Red calipers, (195) Ebony interior, (38S) Red
custom leather stitch and (RUR)

The only thing required on the Z06 vs the ZR1 is the addition of either the F55 suspension or the Z07 package. I really doubt that the F55 suspension increases the weight of a Z06 by ~60 lbs and if the car has the Z07 package , it has the lighter brakes(GM says 44 lbs lighter)from the ZR1. That should make the delta between the two, greater, not lessor, as the rag you quoted claims.

PS- if I took on the various rags to correct the mistakes they print, I would have to spend full time doing so, along with an army of helpers.[/QUOTE]

I think your statement has to do more with the NA bigger engine in the Z06 and the smaller SC one in the ZR1 that doesnt get a chance to use its capabilities on the smaller track. If I had the money Id buy the ZR1 over the Z06 uz I do straight lines and not tracks. But preference will dictate what you buy along with income.

Interesting MT:

2006ZO6: 2225lb

Centennial: +~90lb (ZR1 brakes and Suspension; Lighter wheels and tires)

And as I have been pushing:

5.5L 450hp 30/20MPG would be enough with:

A 5.5L 600hp E10 to 750hp E85 FLEXPOWERED MAX limited, ramped up, and controlled

Dynamic for Dynamic!

You might as well get over it. GM (Obama Motors) is going to force horspower down on the future. I spoke with a very knowledgable gm exec last month. A v6 is 3 years out.

johnglenntwo

A 3100lb 3.6L 400hp E10 to 460hp E85 FLEXPOWER



Call me

QUAKEJAKE

No worries as long as the C7 at 440 is 2800#'s and awd.leaving

RACE U

I hope you are right...........if so, all the forces in the universe will be balanced.

I just still think you will have some diehards that will have a stroke if a vette moves back to a v6 (after 60 years).

Reciprocal

Corvette never had a V6. Please don't have a stroke over it.

0WildVettes

Technically correct.

jackhall99

Another correction: The last 6 cyl. Corvette was offered 58 years ago in 1955.

johnglenntwo

And I have read GM promises a V6 Vette won't happen, but, times change. And a part time CLEAN fuel packing 107 octane could spark all kinds of new thinking!!!

The CCXR is an "environmentally friendly" version of the CCX, powered by a modified twin-supercharged V8 engine from the CCX, converted to use E85...

http://en.wikipedia.org/wiki/Koenigsegg_CCX

Tuners are converting ZR1's so when will someone wake up? Race cars! It is ALL obvious!

The key is if they want to make e85 more palatable they there has to be a pay-off. 5% more power wasn't enough, but, 15%+ will have people using as much as possible!!!! I guarantee it!!
