The C63 actually gave me the most competition out of any car I've ran. I was just cruising with the Top Down in the Vette tonight when these two kids (looked like they were in high school) roll up on my drivers side and yell out if I want to run it. I gave them a nod, downshifted to 2nd at 50, gave 3 honks and we were off (road was wide open). I immediately pulled out 1/2 car, but he stayed pretty close with me. By 120 mph, I was only able to pull about 1 and 1/2 cars on him. I was shocked. I was starting to gain on him a bit quicker after 110, and if I had the Top Up and he didnt let off, I probably would have pulled more, but I was impressed for a sedan

Anyone here?

Top down killed your perf big time....Given the curb weight advantage in the C6 vs C63 w/pimple riddled pilots, you should've easily pulled more lengths unless they had a tune, the C63 is neutered in oem form.

Seems like an outcome I would expect, but that Top-end LS3 (I am assuming LS3) power is good til the brick wall of fifth gear after which the C63 might actually start slowly pulling back.

It looks like he was stock. I raced my friend c6 LS3 coupe from 50 2nd gear to 120 i pulled on him by 1 car. That was when my car had a tune only.

By 5th gear your doing 150 mph, and the pull is not THAT bad considering you're doing 150 already. What is the top speed of a C63 anyway?

BTW, my Vette is 100% stock (performance wise)

stock limited to 155mph. I did 200mph in my c63 i have headers and tune and it felt here is more.

Safe assumption OP is an LS3.

Bah! Completely forgot C63's are limited to 155.
Didn't know C6's 4th ended at 150, I thought your gears stoped a little earlier than the Z06's.

07 LS2 Z51 MZ6 (bought new)....personal best 1/4 mile at Englishtown of 12.38 @ 115.86. The LS2 is not that much slower down the track than the LS3 for whatever reason (especially when modded). With the vette, its truly all about the driver

The Z51 has the same 3.42 rear end and gearing as the Z06. Z51 vs. non-Z51 is about a 0.2 sec difference in 1/4 mile.

I wasn't able to search your threads or posts but how did you document 200mph? Also, what does a header/tune C63 dyno at?

Nice times. LS3s are 116-118mph similar conditions, correct? With your top down, I would have assumed the C63 would do a little better, but very plausible.

I was driving to california and i pushed the car to 200mph thats all. I am at 483WHP.

[QUOTE=alqamzi;4027229]I have seen a tad over 200 in my SL55 as well. In the west, we still lots of "in the middle of nowhere" places that you can have fun and not end up in front of a judge!

[QUOTE=IngenereAMG;4027737]I don't doubt the capability or the opportunity, but how much speedometer error is expected or did you calculate based on the gearing and tachometer?

callmedoc

That's about right....highest i've seen stock is 120 mph

Deuuuce

In person? It seems it takes mods for a stock C6 to hit 120mph:

You will need mods on a C6 to get into 120's
