Agreed, BUT unfortunately I doubt they're gunna be significantly different when it comes to weight...point is, the latest Z06s are getting rather porky and most certainly don't have anywhere near the 200 lb advanatage over the ZR1 that they used to.

Cheers, Paul.

Where did you get this from? I've never seen or heard anything remotely close to that.

So is the carbon Z06 lighter than an 06 Z06, which is the lightest?

berryvette

Thanks again guys for all the comments and replies.

OldDominion

Community consensus is that the 06 is the lightest of them all, and they get progressively heavier as the years went on be it due to creature comforts, sound deadening and the like.

As many previous posts have stated, there are too many variables for a truly objective analysis. I will however forward this bit of info as fodder for comparison. Car & Driver's annual Lightning Lap runs - pits stock vehicles driven by same drivers on the same track; a relative test of a stock vs. stock car on a given track. The most recent run (check the list here: http://www.caranddriver.com/features...to_2011_page_8) featured a new Z06 with the Z07 package, which ran the lap in 2:53.5; a ZR1 tested a year prior, ran the lap in 2:49.8. Granted, there are plenty of variables here (n/a vs blown, tires, suspension differences, weight, brakes...etc), but given the 132hp advantage the ZR1 enjoys, for track work (road course), the times seem awfully close... so to further a relative, somewhat subjective comparison - like rwhp bet. both cars in this example, seems to favor the Z06.

No.

The Z06 with the Z07 package is A LOT heavier than a base Z06.

Its 137 lbs heavier than a 2006 Z06.

Actually, the differences between the two are:
- Mass
- Engine aspiration

The Z07-equipped Z06 has the same suspension, brakes, and tires as the ZR1.

What would be more interesting would be another test of the 2010+ ZR1 with the PTM activated, vs. the 2009 they tested originally.

Yes no tracks are equals, but there are plenty of stock zr1s running in the upper 10s consistently. I might point out that if he has 712 rwhp, maybe it is to much and he can't get it to the ground? I have seen that happen plenty of times. I forgot who said it on here, but it has more to do with the driver than the car. Ranger in a stock z06 would probably consistently run circles around me in my zr1.

[QUOTE=LEAVINU;1577025919]I wouldn't call a "good driver" someone who can only run 133mph in a 712rwhp ZR1 and get beat by a Z06 on the road course by 2 full secs. QUOTE]

You are absolutely right on. I believe the Lingenfelter zr1 with similar HP was in the low 10s or upper 9s in the 1/4 at a speed of 145 mph.

I have seen several people state the 06 z06 was the lightest. But what have they done over the several years that has increased its weight so that it is closer to the ZR1? I just don't recall any major differences being announced.

Just curious.

I just read that the Z07 package you mention above has the ZR1 brakes, tires and suspension, but does not have the extra carbon fiber. So by using these stats to say that an hp upgraded z06 will outrun or potentially do so on a track is not accurate. However, an upgraded z06 with the z07 package just might, all depending on how it is done (n/a, supercharger, turbo, etc.).

Who cares, both cars are great in their own right.

The ZR1 has plenty of potential and yes, it is heavier but all being equal, the ZR1 would come out on top due to torque albeit very close race.

Many have asked me if the extra cash for the ZR1 is worth it over the Z06 and my answer is always this: "It all depends on what you consider valuable to you". If looks, uniqueness, newer technology, brakes and so on are your thing then yes, the ZR1 is your ticket.

It has been our experience around these necks of the woods at the tracks, road course and mexico when all stock, the ZR1 pulls ahead but not by much. However, repeated runs changes things for the worse on the ZR1 in a very dramatic fashion and after dyno'ing a few of them I realized why...the supercharger and the ECU do not like each other very much when heat climbs.

This Texas heat does a number to those ZR1 machines; any forced induction platform will be more finicky to heat vs. an N/A application. When the HP levels are equaled out, it is easy to predict a winner if all being equal (driver, traction, tires and track)…the Z06! Manny of my ZR1 customers make the switch to E85; this stops all the harassments from those lightly modded Z06’s. A tuned ZR1, with pulleys, exhaust and E85 changes the game dramatically for the better. AND when the ZR1 gets meaner (heads, cams, boost-a-pump and bigger injectors) the game is really over…I called this my Machismo package.

Hope this helps

Thanks,
Carlos

You guys make me laugh with your heroes.Those wicked times are always run at a prepped track so lets see them happen at a regular track or simply hand him someone else s z06 and see if the times are so amazing i d really be curious.The rest of the world has to run good year run flats to be recognized but for others a prepped track is not an advantage.Makes me laugh.You guys bought a z06 for gods sake instaed of beeing a spectator learn how to drive it properly.

their was already a guy on here who posted a vid of his cam & bolt on z pullin a stock zr1 from a roll. do a you tube search:

Not exactly same RWHP for one. the zr1 had 200 miles on it. it made 510 on the same dyno the z06 made 570. as for the race the zr1 hit rev limiter in third on the first run and backed out. the second run was much closer and the zr1 was shifting at 5500 due to the mileage on the car and hitting rev limiter the first time. i was the one driving so i know. and i know what h/c z06's can do, i have had 3 of them and have been to the track and run 10's. all in all i would still say the z06 will have a slight advantage with same whp but would be very close.

[QUOTE=WhiteSneaky-PR;1577101545]I call him a bad driver. Here is the link of the record 10.6.. 1/4 mile run in a ZR1 with slicks and 10.74.. with stock tires. Three videos for you to watch. I now it is from the ZR1 forum and you appear to ignore anything posted there.

Plenty of other posts in that forum of most stock cars in the 10s, if you care to take the time and educate yourself.

Look at the Nurbring, a course that takes everything into consideration (lots of turns and one long straight away). If you upped the Z06 power to the ZR1 (without changing anything else) it would not make up the 23 second differential (zr1 7:23 - Z06 - 7:46). It would not brake, handle or turn as well as the ZR1.

A 2006 Z06 1LZ is the lightest Z by a....."weight" for it....2 pounds over an '07 1LZ...sound deadening material only in the 2007 is the only reason.

But yes, the facts do support your statement....
