I addition to what I said (read above). You might raced a person with a C6 with flare fenders. A lot of wannabe Z06 owners buy rear quarter panels and other used Z06 parts such brakes or even front bumpers.
As far is the LS7, the motor could easly be a 6.0L (LS2) or 6.2L (LS3) with just a LS7 red plastic cover, again, many people will do that to impress when they can't afford the real LS7.

Are you sure it wasn't the Grand Sport?

 

I believe the story. I witnessed a roll where an SLK55 (headers, renntech intake, BMC filters) was dead even w/ a C6 Z06 from 60-120mph going uphill. I was just as surprised. I would guess that eventually the Z06 would start to pull away, but neither gave an inch, all the way up to 120mph when they shut it down. Needless to say, the Z06 driver had a stunned look on his face. Excuses can be made such as:

1) the Z06 wasn't in the correct gear
2) it was a rebadged normal C6

I would say that #1 is possible, and #2 is very unlikely. As a witness, I would say that both are unlikely. As a side note, this modified SLK55 has pulled 1-2 car lengths on stock C63s from a roll and a dig. For reference, it has also run even with a stock W211 E55.

 

Sometimes

 

Wow - 800 rwhp? Any link to the dyno sheet? That's impressive...

 

I believe the OP story and thanks for sharing.

I love the fact whenever someone brings up a Z06 people start quoting that they do 60-130 in 7.86 seconds. One car did that and that's Divexxtreme on 6speed, which I will add he's a very exceptional driver with a ton of experience. In reality they do 60-130 times with a very good driver in 8.6-8.8 seconds, which is still fast as hell.

Yes there a couple of people that have taken the Z06 to a 10.9 @ 128-130 in a 1/4 mile. Once again an exceptional driver that lives to race. Not to mention this is done at MIR which is a very fast well prepped track sitting at sea level. Time and time again I've seen Z06's run low to high 12's with the average joe driving them. All driver dependent and anything could happen on the streets.

 

So this thread is still going? still comparing 2 cars that are have nothing to do with each other and have very different specs including the HUGE difference in weight...

 

good story

all in all what I got from this thread is the zo6 is a beast and we should all stop wasting money on headers and exhuast and just buy one..

 

You want to run me?

 

Haha that's funny? Never stop!! There's are not many four doors out there that can do what we can

 

LOL!!! Awesome. And touche.

 

You're welcome. And thanks for the good response. I agree with what you wrote.

 

Haha! I know, right?

I heard a cammed and headers Z06 start up and rev it's engine and it sounded amazing. One of the best sounding cars. Even stock, they sound more aggressive (read "louder") than a stock ZR1.

But, I have to agree with dodger63 on this one. There just aren't too many sedans that can handle and accelerate like the C63.

 

You know what, the car was black and I really wasn't looking it up and down. I actually thought it was a C6 Vette and I was still thinking that a C6 Vette should pull away from me but after the run I definitely saw the Z06 emblem.

Like you said, people can make their regular Vette look like a Z06. It's possible.

 

Power is power. It sounded clean.

 

Well, at least you gave me some options. So, thank you for that much.

It's interesting that your experience driving a stock Z06 is slower than some of the fastest stock Z06 ET's. Of course, props on your time and getting out to the track to test your car and enjoy it in the process.

Similarly, your experience driving a stock C63 is also on the slow end of the ET's. In fact, I would be quite upset if my stock C63 runs a best ET of 12.9. I haven't taken my car to the track yet, but when I do, I sure hope it runs faster than that.

Given your experiences, and knowing that both a stock Z06 and a stock C63 can run up to a second faster in the 1/4 and in the C63's case, a higher trap as well, it would seem entirely plausible that on a random day on a random fictional road, a C63 could run a low 12 sec 1/4 while a stock Z06 may only run a couple of a tenths faster.

Everyone knows that weight is a huge factor in a race. But not every race is a perfect run on a nicely prepped track with both drivers driving their cars the way they practice on the 1/4 mile. Yet, even with weight playing a huge factor, your stock Z06 only managed a couple tenths faster than some stock C63's in the 1/4. Obviously, then, weight and rwhp are not the only two relevant factors.

 

True - respectfully, though, you may have missed where he stated he's racing at over 3,000 feet above sea level. Thus the relatively slow times (when compared to the fastest cars of the same makes/models racing at sea level in good DA).

However, assuming both cars were run in somewhat similar DA and at the same track, the results can be compared to one another w/o being apples to oranges. I think that was C63newdude's point...

 

You guys will probably like this since it involved and M3:

After a 4 month absence for the GT2 (which is making about 650-670 rwhp or more on pump gas now), upon getting her back I have been trying my best to be a good boy and obey all posted signs limiting speed

However tonight as I was at the stoplight about to get on the feeder leading on to the Mexican 59, a new M3 Vert pulled up next to me with two 20 something gentlemen.

Seeing that I was obviously much older and thus unlikely to respond to a challenge the driver revved his motor and when the light turned green launched the M hard. I quickly rowed through first and second and by the time the diverter valves wailed I was up 2 lengths. The feeder funneled into one lane ramping onto the highway and by the time I was there I had shifted into 4th and was up by 6 lengths.

There was some traffic so I slowed to 70 but soon had a large stretch of open road ahead of me. The M was almost upon me and I shifted down into third and once again opened up a several busslength lead.

With more traffic I pretty much shut down and the gentlemen pulled up next to me and being good sports gave me the thumbs up. I returned the favor and pulled off the highway.

When I checked my boost controller I saw that I was running 1.32 which is .4 tenths more than I have been cleared to run on pump

In any event, good times and I think I had better work a bit harder on behaving myself.

 

HAHAHA that's my video and that's my car with me driving...

there's no way C63 (stock) can keep up with Z06...on that day, we switched car...and WOW...i know c63 is fast...but Z06 is on different league...

Btw, that's my second day after I got my c63 :p

 

A real roll race from 60 to 120mph on a Z06 the Z06 will win. A HP tune on the Z06 raises the red line to 7200-7400rpm and that is 100mph in second gear. You only have to shift once from second to third. The Z06 is very fast even in 4th or 5th gear from a roll at 60mph.

I can only see the C63 taking the Z06 if the guy in the Z06 was actually rolling in 6th gear thinking that he could take the c63 and by the time he shifted to 3rd gear or even 2nd gear the C63 was ahead.

Liek I said, I owned both cars and it is night and day stock for stock(Z06 wins all the time).

 

Not bashing you but I really love this part... Have you ever heard of the NHRA altitude convertion chart? Well, when you run at 3100ft elevation plus heat plus on 91 oct it slows you down.

My 12.0 Z06 run is a 11.5 at sea level (conversion of .9640 rate) and my Z06 122mph speed is 126.55MPH (with the conversion rate of 1.0373)
As per the C63 running 12.9 would have been a 12.4 ET and a speed of 114.64 (from 110.52).

http://www.nhra.net/tech_specs/altitude.html

There are a lot of people making claims out there, all I can say is bring it to Tucson or Phoenix and run 91oct like me and run in the heat at 3100ft and now show me how many can run low 12s on a C63.NONE.

I can run probably 9 sec 100 meters going down hill with the wind blowing my back. Try to run 9 sec going uphill. I am being sarcastic because it seems like no one ever heard of the altitude conversions

 

I've heard of altitude conversions. I missed the fact that you mentioned your altitude in the post I was responding to. So my bad.

Btw, I also understand heat and 91 octane because I live in the desert, in CA where it's been 110* F + on many days this summer.

Anyway, thanks for your input.
