Does anybody know how our car (C63) stacks up against a stock Nissan GT-R? I presume the GT-R would win a 0-60 race (higher stock HP and AWD) but how about after that? 60-100? 60-120? etc.

Anyone got any first hand experience of racing a GT-R?

The C63's 0 -100 is around 10 seconds while the GT-R's 0 - 100 is listed as 8.5. I saw a GT-R throughing down laps at Infineon in a different group that I was in and it was FAST.

No, No, No, and No.

I raced my friend with my 55 and lost all the way...

The GT-R would obliterate even tuned C63's at any speed to any speed.
My C63 is bone stock and it was bad, but I think C63 guy or Keith could chime in with real world tuned C63 vs GT-R stories.

We are talking about a whole diff league here and theres no comparison even at 60-120 MPH.

You guys are kidding right? The GTR may win in a 0-60 but not in a flat out standing mile.

There were (3) tuned C63's at the TopGunRun in Miami. My personal car is the one that ran 172.14 MPH.

There were also 2 stock GTR's and a modded one. As you can see the ECU Tune only C63's beat the both stock GTR's. No way we can beat a modded GTR.....

Here are the results in the mile in MPH.

2009NissanGTR166.36
2009NissanGTR169.87
2009MercedesC63AMG168.26
2009MercedesC63AMGModernHorsePower172.14
2009MercedesC63AMGModernHorsePower180.73

It would be a tight race.... About even I would say...

The 3 C63's including yours certainly were very impressive in that 1 mi. run. I wonder what the story was with the one GT-R running 166mph? Those GT-Rs are just ridiculously fast!!!!

FWIW, some of the tuned GT-R's can be just devastating! My friend, "sleepdoc" just texted me today that he just ran his Cobb custom tuned GT-R @ PBIR for a new record...10.41sec. @ 133.58mph...w/ stock turbos, DRs on 93 octane!!!!

They are certainly fast monsters out of the hole but I can only assume by the results that the GTR's loose ground to our cars on the top end of the mile for some reason.

Maybe Keith would have a better answer.

andy_meng1024

I think the OP is talking about stock vs. stock. An ECU tuned C63 would have more HP than a stock GT-R.

GT-R is a legacy!! they gooo waayyy back! one of the best japanese "super" cars every built.

from R31, R32, R33, R34, to now R35 =] each generation has gotten better, and better, to the point where now the R35s are running up against prestigious and well known high end automotive companies such as Porche's, Ferrari, Lamborghini, Saleens just to name a few.

Seriously, Nissan knows their engineering very well, because since the day the GTR was born, the Skyline legacy has become history in the making!

one of the very few iconic every in the automotive supercar history

Okay, good to know. I am planning to do a couple of track days at Road America in April and there are 2 or 3 GT-R's signed up. Maybe I should stay well clear of them (or maybe I can't get close to them)! I know they have the advantage in the corners but I thought we might have a chance on the straights - and Road America has couple of long straights and is generally considered a HP track. I plan to have a K1 tune done before I do the track days. However, I don't know if those GT-R's are stock or tuned.

Raleighc63

Personally I would go with MHP. I know they are more expensive but you get what you pay for.

2 of the c63's on the list that beat the GTR's have MHP tunes.

I'm not saying anything bad about the other guys but I am very happy with my tune..

SGTzAMG

DOO IT! dont think of it too much GTR vs. C63 AMG
just go out there and have a bllaasssttt! both cars are two different beast

take pics and VID!!!

I will have fun for sure and I am proud of my C63 so that is why I was wondering about the performance of the GT-R and how close (or far) it will be from mine. I know that track well (from doing many track days on my motorbike) but this will be my first track day in a car. Hope it doesn't snow!

How much power advantage does the MHP tune have over the Kleemann? I'd kind of settled on the Kleemann tune due to all the positive feedback from members on this board.

SGTzAMG

im excited for u maaaan

Raleighc63

I cannot honestly tell you what the power advantage is.

I had a Kleeman and Renntech tune and then decided after dyno results to go with MHP.

Who ever you use make sure you have a baseline dyno done first.

I gained 65rwhp (81HP) and 28rwtq (35TQ) from the MHP tune..

I have 531HP & 483TQ (using 18%)

So, you seriously spent > $7,000 just on ecu flash tunes for your C63? Sorry, but that's just . Enjoy it though.

Dads C63

In my experience they are two different beasts.
A stock GTR vs a stock C63 we'll get walked on.
A tuned C63 vs a stock GTR you will hold your own and possibly win long runs. You will still get hammered in the short runs.
A bolt on L/T headers, tune, etc.. C63 will walk a stock GTR top end. A friend of mine has one and we raced together at Roebling Road and he couldn't stay with me on the long straight away.
However, thats where it ends. When you start tuning a GTR they get nuts. They already run low 11's in the 1/4 mile bone stock using launch control. Then the tuned, down pipe, etc.. they are running mid 10's at over 130mph. Thats where we get our butts handed to us.

They are both great cars but set up for completely different performance.

sflgator

100% agree. I'm sure you've seen sleepdoc and Fikse's Cobb custom tuned GT-Rs.

SebringSilver

"Quick" and "Fast" are two different things, folks.

Ron Scarboro

I have both a bone stock 09 GT-R and a bone stock 09 C63 AMG (Performance package).

Although the C63 can feel as fast sometimes because of the turbo spool on the GT-R vs the immediate response of the big V8, on a Pbox there is no point in which my C63 is in the same league with my GT-R. It just doesn't matter anywhere to the point of redline / governor 0-60/60-100/100-150.

FWIW, many GT-Rs are sleepers (don't know if mine is or not). I know it isn't as accurate as a dyno (neither of my cars ever have been dyno'd), but on the PBox correctly programed for weight on the same patch of road a 2nd gear run to redline gives 353 peak hp for my C63 (best run) and 424 for my GT-R (best run) at the rear wheel.

Further, $995 for a COBB and you get 50hp more with no other modifications. 70 with a mid-pipe for another $700. Sky's really the limit with the turbos. There are guys over on the GT-R site getting 800+hp with programming, injectors, and complete exhausts.

On a track doubly AVOID.

Excellent information and you certainly would know as you own and drive both cars (lucky you). How do they compare in other areas, ie. sound, confort, ride, cost of ownership, daily driving, etc. I've heard that GT-R's are really expensive to maintain and they require a lot of it. Also, I hear that the list of things that voids the warrantly is huge (including putting the car on a dyno or driving with the VDC off). The C63 must be easier to live with and it sounds fantastic and pulls very strongly.

Raleighc63

SFLGATOR - Yes I did spend a bunch of money on the tunes and for some reason the only one that actually dyno'd what the manufacturer claimed was MHP.

I certainly don't want to get into an ECU tune war but I did try and purchase all 3.

Kleeman was kind enough to give me my money back immediately. Renntech is still refusing to refund the 15% restocking fee from the original $3200 I spent on the tune. I am disputing this with the credit card company.. And yes I spent some bank on the MHP tune, but it did dyno what they claimed.

I'm sure there are believers and non-believers for all tunes..

BTW - Ron Scarboro - I noticed that you live in Raleigh. Hey, so do I! We should meet sometime and compare cars.....

If your gonna run a GT-R do it from a Roll, then you won't look as bad. thats it.

don't do it from the Dig. You might have a slight advantage because of the ridiculous torque if you start at second gear around id say like 40-50 mph.
