Tom did not answer I will try to get real info by the end of the day not internet crap. one way or another.

I've already said four times that there were year to year differences. Oh and I don't give a single **** what Tom says as my information comes directly from the ECM GM tuned.

Someone posted in that the value for an ls3 car that supposedly drag limits at 192 is in the tuner 195? So ironically the car may have a speed limiter past its drag limit????

There was another post that said that the Z06 has a 205MPH. which Ironically is past the claimed 198 drag limit. which if that turned out to be true would be funny to me. GM imposed a speed limit at a point the car is not supposed to go ha ha.

in the long run it is all useless knowledge but now I just want to know the real answer.

okay here is the Info I believe to be correct at this point. I was wrong and the car does have a Limiter but depending on which model you have you most likely could never reach it anyway. The speeds at which the limiter are set were incorrect or not complete in the above posts.

2005-07 LS2 186mph (due to the tires at the time speed rating)
2008-current LS3 195 (beyond 192 drag limit not sure why the number was chosen)
2006-current Z06 205 (beyond 198 drag limit maybe due to stabiliy like the ZR1?)
2009-current ZR1 205 (due to aerodynamic stability was stated)

see stupid people can be good for tracking down info because were are too stupid to know it doesn't really matter ha ha.

So instead of pretending to be smart why not just hook a tuning program up to your own car? You don't have to alter the program to look at any of the parameters. It is funny to see how hung up you are on this "drag limit" stuff though as none are actually drag limited to the numbers you posted. In any case it's funny how things have changed in less than one page. First there are no limiters and I'm full of shit and now you're bitching about where the limiters are set at.

funny how you say you were right but you were also wrong. you said the Z06 was limited to 198 which is not true. You said the C6 is limited to 189 wich is not true.

I brought up the drag limit because a stock Z06 really proably won't go 205 so it has a speed limiter past it speed limit. Fastest I have ever seen a video of stock Z06 was 202 on is speedo and hud.

I know understand why most people belive there is not limiter on the Z06 because without mods you not really going to get to its limit.

Actual gear or horsepower limits are:
Base = 190 to 192 (depending on gear ratios)
Z06 = 202mph
ZR1 = 215mph


And with that being said the ZR1 is more of a race for a base model C6 than it ever will be for a Z06.

the bold info is incorrect in one way or another.

Yep.....the ECM "speed limiter" numbers mean nothing, as the Z06/ZR1 are drag limited. Once you're modded and can exceed the stock Vmax numbers, it doesn't matter what the original program value is/was as it's also changed in the tune.

It's a moot point to for anyone to continue to arguing the point.

How many times do I need to say that there was a range of speed limiters across the productions years? In any case you are 100% wrong as you said there were no limiters period and the fact that others didn't know means nothing. The numbers I litsed were at some point correct as they were taken from stock tunes written by GM on actual cars.

And I don't give a **** about all your drag limitations as that was not the debate from square one. It was simply about the fact that they have a electronic speed limiter and that was all.

They mean plenty as someone said they didn't exist and they have now been proven 100% wrong.

I hate to revive an old thread....but I went to the 1/8th mile drags tonight with a friend. 1/8 is the only thing we get here. He drive my C6Z06 and I drove my bone stock L99.

It just so happened a red ZL1 showed up......
We hung with the Zl1, a H&C Gen4 Camaro, and a maggie charged camaro.

-My Z06 (stock power with nitto 555s and race seats) ran 7.3s-7.5s (faster with AC off I told him, but it was warm in staging)
-The ZL1 (stock M6) consistenly ran 8.6s-8.8s (with the launch thing?)
-The Gen4 Camaro Vert (a4) ran 8.3s-8.4s (Nitto DRs)
-My L99 (the big Chubby) couldn't break 9....9.01 was fastest with .22 r/t, car seemed to stop pulling half way down....I thought I was going to break the throttle pedal, I was pushing so hard.
-The Maggie Camaro ran 8.1-8.2.

But the most impressive thing I saw was a Whipple charged SVT Lightning 2002 Ford Truck......ran 7.2s....that thing was cool....and beat the Z06...found myself wanting an SVT lightning.

Now all the drivers had varying experience, but nobody complained about traction. After seeing the difference in the Z06/ZL1 time its hard to imagine the how the ZL1 could ever overcome the weight disadvantage, so its not even an argument.

I tried to take video but its hard when you're driving and when I skipped a round.....there was too much glare as the end of track faced the sun. It was a good deal though...$20...as many runs as you can get in 3.5 hours.

Personally, I think the ZL1 would be lucky to beat a C5 Z06, let alone a C6 Z06 with 100hp more!

Chevy advertised them all drag limited
192
198
205

the LS2's were 186. Now that being said most have not take the cars that fast and the chevy ECM's do have a place for speed limiters.

As for people saying a C6 is slow they are dreaming I ran times in my 08 in the quarter mile that rival anything the ZL1 has done to date but nothing faster than the 12.02 that that one guy posted in. the ZL1 ironically produces better road holding that my Z51 was advertised at.

I've seen times deep in the 12's. To me, that's not slow.

As I explained so well to my lovely wife, the ZL1 is PRACTICAL. Four seats means I can still carry the kids anywhere they need to go and if we need to go shopping, no problem. Still room for bags and bags of shoes and both of us! Plus those Corvettes are soo standoutish. If I drive the ZL1, most regular folks just see a Camaro (that may have been a bit of a stretch). What's so different about owning a Camaro? Is a Z06 faster, you bet. Get over it or get one.

[sammyv]

Let's see, how many ponys does my ZL1 need to equal the power to weight of my old Z06? Looks like 654!

[Camaro_hx]

If thats true, GM are getting confused with their vehicle segment range.
