Arrow 05 GTO vs 08 CLS 63 AMG

I own the 05 GTO and little brother owns the 08 AMG (listed at 507 hp ).
Both on street tires and from a 30 MPH roll. Even through 2nd gear (for me 2nd as I have a 6 speed don't know what gear his was as it's a 7 speed Auto) catch 3rd (tire scratch and all - Love it with TC off!) and that damn 4 door starts to pull HARD! By the time I'm in 4th he's solidly ahead by a 1 - 1.5 cars. Gap didn't get any bigger nor do I close it any. Ran it back a couple more times, exact same results.
Felt pretty good with the results since we both know that damn Benz HAD to be faster than the GTO (in stock configuration). I mean, whatever combination of gearing they used in the tranny & rear, AMG got it perfect! That damn 4 door pulls like a freight train when you step on the loud pedal (and the trip-tronic shifting is fun!) I wouldn't of paid 100 Large plus luxury tax (neither did my brother) but it's a nice *** car none the less.
I have Long Tubes, Under Drive Pulley, Cam-Pushrods-Springs I plan to install during the week. After the install and a tune, the re-match shall commence. I'm fairly certain that the car positioning should be swapped

Hmm.. Most people that would spend 100K on a car wont even bat an eye at throwing a little cash at the performance upgrade.

We're not "Most People". Not to mention, he bought his for 48K with 29K on the odometer.

The final drive ratio is actually pretty bad at 2.82:1 for the '08.

The 7 speed tranny with the 1:1 at 5th gear definitely helps, but the gearing isn't really stunning:
1st, 4.38
2nd, 2.86
3rd, 1.92
4th, 1.37
5th, 1.00
6th, 0.82
7th, 0.73

I've thought the AMG mercedes' were pretty amazing since 03 with the release of the E55 AMG.

That's a pretty cool car your bro has, same goes for you...

actualy, if you would of been in 1st gear at 30, that would have been a better pull right off of the bat... if you were in second you wernt quite yet into the power band... i think...

I guess on paper it looks bad but in actual operation, that damn 4 door is responsive as all get out! You can be coasting along at 55, stomp the loud pedal and it down shifts and starts eating up concrete like a GSXR.

Never cared much for the Benz brand (even there is one in my driveway ). The maintenance vs resell value is **** at best. I've always thought of them as a car you better like A LOT and plan on keeping it A WHILE.
Though as I stated above, that damn 4 door [b]MOVES![/b ]

I don't see it being a slaughter but I am hoping for the victory
I don't know if you've ever driven/rode in that CLS 63. If you haven't, first chance you get jump at it. That motor/car is truly impressive. Not 100 large impressive (I don't think a car has ever been produced I'd spend more then 45K on) but worth what he paid for it.

I don't think so. I've been dealing with pushrod motors a good part of my automotive life. The LS2 is a good breather up top but I don't see how being able to run out first gear for another 1 second (or less) would of been a gain. We went full throttle from 30. I was only in 2nd for a blink of an eye (it seemed). I can only imagine how short 1st would of been. Who knows, I could be all wrong (wouldn't be the first time )

Will do (plan to get video as the idiots on MBworld.org refuse to believe that they're Deity didn't put more distance on my domesticated "junk.")
I got a cam package from TSP 226/228 578/581 (i think, don't have the paper in front of me) with a 114 + 2 LSA. Got coated PaceSetter 2nd Gen long tubes and mid pipe with a SLP Underdrive pulley.
Should be enough to even out the power equation. Looking to get close to 400 to the wheels which is a bit less then the CLS63 but the CLS is about 4 - 500 pounds heavier.

Thanks everyone for the replies
