The base C6 can't house the wide tires of the Z06 or the ZR1. I enjoy Road Racing and for me it makes sense to go C6 Z06 so I can fit some really wide Road Race tires on it. Should also let you hook some of the power of the Twin Turbos. Again if I was a car collector I may have a different attitude but it just doesn't work for me. I'm not a fan of the blower either. Give me a Twin turbo with a boost controller on it. Allows me to control the amount of HP that I need on the specific track I'm on.

So the ZR1 doesn't use 6th gear to race? Or has a tighter 5th/6th gear setup than ANY OTHER GM 6 speed car STOCK from the T56 and beyond?

So you are saying that when WOT on a roll ABOVE the torque peak you mentioned, that torque peak is the ONLY reason why it is pulling?

Have you driven a C6 Z06 or a C6 ZR1? I have, hard. If so, did you not notice the difference in the 5th gear of both cars, let alone when you throw 6th going to stupid fast... did you notice a difference then?

That torque, that helps when pulling from lower in the powerband (I.E. off a corner) not in a roll race where I'm always over 4k rpms or prefer to be, has nothing to do when involved in a roll race like this. The gearing of the ZR1, its much shorted 5th gear (than a Z06) and close 6th is the a MAJOR reason why that car just moves hard over 160mph where I shift out of 4th into 5th.

Well, if you do a fender swap you can make it work but the notion that this isn't a ZR1 is just absurd.

There are some cool items on the ZR1 that do set it apart. The brakes for one. Those would be absolutely perfect around Road America where you can really stretch the legs of a high HP car that has excellent brakes.

I hear the new Carbon Fiber Z06 is coming out soon. It comes with the brakes and the carbon fiber panels the same as the ZR1. Course I'm sure it'll be about 90K.

I'm done buying new cars just to modify and race them. I'll buy the used ones and have my way with them.

I was going to say the same thing..... a lot of C6 owners get the Z06/ZR1 rear panels and put Z06/ZR1s wheels on the back.....!

YEah, the new Carbon-Z06 will have some of the goodies from the ZR1.

A new hood, designed after the ZR1 without the window in CF. the CC brakes, CF roof and halo, Wheels/tires, chin spoiler, side skirts and rear full length spoiler. Oh, and I cannot forget about the magnetic ride! Also, it has a few touches for the interior like suede inserts in the seats, shifter and steering wheel like the new CTS-V.

All and all, the car is going to weigh about the same 3175lbs (mine weighs 3180lbs. full loaded 3LZ) However, what I'm looking forward most to is the brakes, hood, tires and the SUSPENSION. I really don't like the ZR1 chin spoiler as it is too much however the side skirts are cool.

I like it... but when they dont plaster Z06 or ZR1 all over the car...



But I really the rear fenders WITHOUT the scoops, looks stealthy but got some junk in the trunk... who doesn't like that!

Deuuuce

No, but I crunched the numbers on a spreadsheet because I was curious myself. Used C&D numbers. R&T seems to use estimations sometimes.

The ZR1 has more aggessive gearing in 4th through 6th. It's pulling the Z-06 because of gearing and horsepower.

Z-06 top speed in each gear:
58.8
88.2
120.4
156.8
212.1
313.6

ZR1 top speed in each gear:
63.7
90.35
120.25
145.6
180.05
217.75

If the Z-06 had ZR1 gearing top speed in each gear:
68.6
97.3
129.5
156.8
193.9
234.5

If the ZR1 had Z-06 gearing top speed in each gear:
54.6
81.9
111.8
145.6
196.95
291.2

Why will the z06 carbon fiber still weigh 3180 pounds?????I thought it would be 3000 pounds or so????

I also have a similar sheet.... did you set up to rpm range correctly? Not nit picking and its been a while since I looked at it but my understanding the Z06 hit 60mph or 61mph @ 7k rpms in first, 92mph+ in 2nd, 123mph+ 3rd and so on.... I believe there is something up. Or I maybe wrong as well...



Your using a 3.42 final with the REAR tire overall diameter?

However, notice the top speeds in 5th gear of each car. You can see where the ZR1 is going to pull harder in 5th than a z06 after 145mph. Though the Z06 is still in 4th till 164mph (7100rpms or so) when selecting 5th, the ZR1 is already yanking through 5th and getting to a mph that is shorter than what the Z06 is set to with its tall 5th.


Official weights, i believe, haven't been posted but the car will probably not get under 3000lbs. or even 3100lbs. One thing that hasn't been posted is how much weight the magnetic ride system, with all the sensors and heavier shocks, will weigh. Also, The car has a larger chin spoiler, new radiator and associated parts, side skirts and a larger rear spoiler. I don't think those aero parts are piggy heavy but it all adds up.

As a comparison, you can get a Z06 under 3100lbs with just headers, battery, clutch/flywheel, wheels/tires, pin-on hood and for sure, if you do the seats, get her damn close to 3000lbs or under than with fixed back seats. (Our seats have an airbag system and they are heavy!!!!

I believe katech's clubsport tips the scales under 3000lbs or something around 2970lbs. and I think it doesn't even have headers. Now add a mild lethal Z cam, heads and bolt-ons and you can have a 600rwhp N/A pump gas Z06 weighing under 3000lbs.!!!!!

Deuuuce

I did use 7k and 6.5k and C&D for consistency. Not sure if they calculate rear tire diameter but I believe they do.

Fadi

First of all, a CGT won't hit 0-150 in 13.0 secs. A CGT is roughly a 130 mph car, so is the ZR1, and the ZR1 will reach 150 in 15.6-16.0 secs sec range at best. If you think a CGT is 3 secs faster than a ZR1 to 150, well, you are wrong.

Second, the ZR1's 5th gear ratio, which takes it to about 190 mph, is a close ratio, but 6th gear is still looong. While the Z06 pulls hard to 160 and then dies, the ZR1 pulls hard to 190 and then semi dies.

Lastly, damn, that CGT got walked. But, that is to be expected from a 750+ HP car vs. a 600 HP car.

Right! I was wondering if that time was right because by the time a Z06/ZR1 hits 130mph or so (11-12 seconds) that CGT would be about 150mph!

The 5th in the Z06 is just a dog but no nearly as tall as the 6th in the ZR1.

Ok, lets try this again....

Here are the gear ratios and mph per redline that I came up with using the trust f-body mph calculator!

ZR1: 6500rpm, (335/25/20) 26.59, 3.42

1 (2.29) 66mph
2 (1.61) 93mph
3 (1.21) 124mph
4 (1.00) 150mph
5 (.81) 186mph
6 (.67) 224mph

Z06: 7000RPM. (325/30/19) 26.68, 3.42

1 (2.66) 61mph
2 (1.78) 91mph
3 (1.30) 125mph
4 (1.00) 162mph
5 (.74) 219mph @ 2k rpms: 63mph
6 (.50) 325mph @ 2k rpms: 93mph

Big difference between the 5th and 6th gear ratio's.. simply put, the ZR1, after 160mph, will just start pull hard!

BUT, look at the Z06 with ZR1 5th/6th gear ratio's

5th (.81) 200mph @ 2k rpms: 57mph
6th (.67) 242mph @ 2k rpms: 69mph

Big difference! Much tighter gearing and will really wake the car up in 5th gear! With enough power, those ratio's would give me enough mechanical pull to content at the local mile event.

The mph in 6th @ 2k rpms is decent enough where the mpg wont suffer to much however, the way the Z06 would pull now, lets say a the mile run, would be just stupid and definitely more fun!!! I'm definitely looking forward to doing this, but I need some baseline numbers.. hmm, where to find a long enough stretch to top out 5th?!

Deuuuce

You might be right. C&D hit 130mph in 10.8 seconds and ran an 11.2 @ 132mph with no prep or powershifting.

R&T ran an 11.3 @ 131.6. It's gearing in the triple digits is significantly more aggressive than the ZR1.

I have no doubt equal drivers it would beat a ZR1 to 150mph.

I think, stock vs stock, the CGT might be a close race. The CGT vs a Z06, the CGT is about car ahead of a Z06 or so.

Mods unknown for the Z06 and CGT.

Don't underestimate what the ZR1 can do, I don't think it can loose since a Z06 is only a car back and the ZR1 is about that and some in front of a Z06. (Intake/tune z06, my old MS Z06, was dead even with a ZR1 though. )

camaro98z28

Are there any videos of anyone crashing yet? But really, the ZR1 is a hell of a car.

Deuuuce

The videos prove nothing except consistently beating C6Z.

No one is underestimating the ZR1. However sea-level trap speeds with no powershifting for a CGT are as high as the best seen from ZR1s in negative DA, prepped and powershifted by the best.

obZidian

iTrader: (2)

ok.

But what you are failing to see is that the CGT with 615hp is beating a 505hp vette by a car. A Z06 is really a 129-130mph car and a ZR1 is about 133-134mph. Think about it.

Also, who cares about powershifts.... EVERY FAST RUN done in a vette either its a positive DA day or not (local Z06 went 129mph stock in positive DA) was done with a lift-shift.... AKA no powershifting. Ranger, Jaimer Furman, Dr.doc, etc, etc, etc..... ALL of those guys don't powershift.

The CGT is a great car and is a tad faster than a z06... but you said that it would beat the ZR1 same drivers and I'm arguing the fact that: NO, it won't. An intake/tune Z06 would embarrass a CGT by holding its own well with 100hp less.

jomo

The Vyron does 0-150mph in under 10secs.
0-60mph in 2.5secs.
It does the 1/4 mile low 10's at 140+mph.

But that's a car you probably wont run into.
