Ah yes I see that now. I saw on another site it was 40%, but I definitely trust what the mbusa site says at 30%. Either way it's working very well.

My concern with the 100% locking is what if you ran on some real grippy drag radial with a lot of HP and dead hooked at the track and started breaking driveline parts. Maybe MB goes with 30% locking for a reason?

Good point.

Incredible results! If we can help anyone with a tune please let me know.

To OP,
Nice times. Congrats. Makes me want a E63 Wagon even more.

This thread was also good for a laugh.

Mainly, I would suggest going to the track to actually see what cars can do. Not basing your facts off of you-tube videos.

My 2002 Firehawk stock was able to run 12.96. How you think C6Z06 run 13's is beyond me. Heck, when I had my 03 Cobra, I was running this guy with a 2003 Corvette convert, auto. All he had was an intake and catback. He was running 13.1@107 in the middle of summer.

My 04 Z06 with just the ziptie mod was good for 12 flat.

I have also personally seen a bolt on C6 Z06 walk a 2.8L KenneBell Cobra cobra.

Corvettes are great cars, don't discount them solely on their make.

Props to Ready2Roll as his runs very are impressive on street tires (Sorry for the re-post but I believe appropriate here as well).

These cars will easily blow the tires away from a roll when tuned, so getting it to hook on street tires was no small feat.

The three runs you posted all were 1.8 60 foot times. Two 1.83s and a 1.84. Same as some of our runs on drag radials. Track prep must have been good.

I would suspect that you must have had a run or two where you spun the tires, had a worse short (60 foot) time and ran in the mid to high 11s. Maybe I am wrong. Nobody likes posting runs of them spinning and running ****ty times.

The 126 mph trap establishes that your car is making good power. And the 1.83 short time shows that you are putting it to the ground. Hartmut just ran a 10.92 @ over 131 mph in his CLS this past weekend in + 1200 DA on a 1.8 60 foot with exhaust mods. So there is more power to come. I didn't get a chance to drive it this weekend. I believe my best best 60 foot to date with the Renntech CLS is 1.7. No 1.6s yet. As such, I think 10.60s are in reach.

That being said on the night you ran your 11.3 at No Problem Drag Strip it was in the 40s with a DA of nearly negative -1000 foot.

So to compare apples to apples (or pick the fruit of your choice), the conditions would have to be the same. The runs with the Renntech CLS are generally in a postive DA of +1000 to 1500. The RT CLS has run in the 11.2 and 11.3 with a 1.8 60 foot (like yours) but in + 1500 DA. In sum, drag radial or not, the 60 foots are the same (1.8). So, in tune only form the cars would run similar times in similar conditions. Your car did have the benefit of 40 degree weather, lighter ceramic brakes, better DA by about 2000 feet, and an LSD.

So hats off to you for a good running car.

Let's keep it real and list the other modifications on Hartmut's car
He was also running downpipes w/high flow cats (200 cell) and intercooler upgrade, light weight skinny's on the front of the car and maybe other mods nobody is aware of? Maybe mixing some race gas? Not accusing... just saying!

Thanks once again. I too think it's a remarkable feat that I was able to run consistent 11.3's back to back with the OEM rubber. No doubt the 40 degree air that night was helping.

Damn that's awesome! Congrats!!! And that Z06 is Badass!

Ready2roll

Thanks my friend!

Oh come now, Mr. 8 Second Z06. You know darn well that once you start modding a car for performance, what the factory spec'd for a stock vehicle is no longer pertinent. Tell us you haven't upgraded hard parts to sustain 1000rwhp whacks...

If you want to take a setup making a lot of horsepower as far as it can go, you have to beef up the supporting components. Or break them and keep replacing them - whatever floats your boat. Gonna cost money either way. Of course you know first hand, so that's not addressed to you.

Ready2roll

Absolutely I know all too well. Everything in my Z has been upgraded to 300M shafts costing many thousands. It's built to the hilt!

My point was is my CLS63 is my family sedan and hitting the drag strip regularly and modding to the point that I start breaking axles is not where I intend to go with this car. I'm extremely satisfied with my tune only and oem rubber. The cars a beast as is and I have no worries of breaking parts!

EcruisinUSA

That cleared it up properly.

<-- This car will never see a track again due to fear of the flatbed.

Ready2roll

Ummmm no not quite!
It will go to the track on occasion.

What it will not see is exhaust mods, bigger inter coolers, skinnys and drag radials. I'm perfectly content with my CLS the way it is.

EcruisinUSA

I was pointing at my W211 E :P

Ready2roll

aaaah, I understand
