Yes GT-R is fast. I raced GT-R on Freeway I was able to keep up with him with no problem. But for Japan GT-R has this stupid 180km limit. So right around 180km he pulled to side and I past him. But it was good battle against GT-R before 180km. I thought that that GT-R is much more faster. But when you go to track I think that is totally different story. Video below is famous track that people do time attack and see what that car can do. GT-R does 1min 2second but C63 is 1min 7 second.

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.....

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.

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.

In stock format the GTR starts to struggle post speeds of 120mph... Down low the car is just stupid fast but the gearing and AWD system robs its hp up top.
And as mentioned ad naseum- the GTR loves mods more than any car I know. A simple 995 tune and mid pipe gets you a low 11 second car trapping in the mid 120's. A few more tweaks and adds and you are in the 10's and above 130 in the traps on a good DA day.
I love the car, its worth all the money and all the mods.

In a 1 mile race torque will win? I think you are a little confussed, In the long run it is HP that matters over torque, torque is what gets you moving, but it is HP that keeps you there and keeps the mph climbing. Aero and HP make MPH in the long run, not torque.

my c63 with the kleeman k2 I beat 2 gtrs that are bone stock from a rolling 40kmh all the way until 300kmh I gave I let him behind me as soon as we passed 180kmh and gave about 3 cars length! And even felt that I was still pulling on him just slightly!!

What track events are you doing at Road America in April? I am going to be up there for one, possibly two events in April with my Black Series. Do you know what configuration you guys are running? Are you running the full circuit with front straight and 3,4 down into 5 (left hander)? I know several groups are now electing to run only the 2.5 mile (approx) circuit which eliminates front straight 2,3,4 and 5, basically just after turn 13 you make a right turn and then a straight shot to turn 5, the real turn five becomes a right hander instead of a left hander and then up the hill. If you know let me know, I am actually looking for a group to run the shorter config with in preparation for the Optima Street Car Challenge regional qualifying event in early May. I have run and raced at RA dozens of times but never run that configuration before.

I know what you mean about the kink - I've run my bike there many times.

I used to race bikes too, CCS, WERA and AMA but depending on how many years ago you raced bikes the kink might be different than you remember, about 8 years ago for bikes only they added "the Bend" after the carousel and before the kink which slows the bikes down significantly (to the tune of about 5-6 seconds per lap), but cars run it wide open, trust me, I have run both with and without "the Bend" in both cars and on bikes, without is wicked. If done properly you are going to clip the inside right strip and the car is going to drift you to the far left side of the track at well over 100mph, just when you think you are going to run out of track it bites and off you go down into Canada corner for one of the hardest braking zones and most difficult turns you will find on any track in north america. Your previous experience on bikes will help tons, but there are sections of the track which can and should be negotiated differently in the car. You know all about turn 5, just remeber you are trying to bring down a 3900 pound car from about 150 mph not a 350 pound superbike, that being said you are going to be able to carry alot more speed through 5 in the car compared to the bike. Turn 6 is tricky in a car because the car wants to get airborn under the bridge and all the suspension unloads as you crest the hill, you better be turning or pointing the car before you get there or it will be too late. The Carousel can be run faster on a bike, your car is going to want to come around on you in that section because you will have the entire left side suspension loaded up and the front end pushing the only real way to get through there quick is to try to use the throttle to steer the car but before you now it too much throttle and it will spin you like a top, It happens to me every time I'm up there and I see a dozen other guys make the same mistake without fail. Fortunatly there is tons of run-off and the spins usually take place well after the Johnsonville bridge.
One last thing, be prepared to replace your brakes, I toasted a set in one afternoon at Road America (about 45-50 laps, 185-200 miles), it is the most brutal track on brakes I have ever driven. All those long straights (3050ft, 2700ft and 2600ft) are followed by slow 90 degree or tighter turns.

Cool, I will look into that event, I would like to get up there again soon.

I appreciate your advice and knowledge. I have riden that track with the old and new configurations before the kink. I don't like the "bend" at all but I agree that the kink is "scary" when accelerating full bore on a bike without the "bend".

I did raced a friend's cobb tuned GTR with my tuned C63. we roll from about 100km/h to about 240. He actually gave me a headstart. Then he blew past me when my speedo was registering 210km/h and he keeps on pulling about 1.5 car length and I could never get close again. Believe me its that quick guys

Our cars are not even close to the gtr performance.You are taiking abt a car that have a twin turbo 4wd and alot of advantges then our cars.You compare gtr with 911 turbo,Zo6,viper not c63.actually am thinking of buying a gtr when the prices go down to mid 50's because its not worth the money they are asking.

So imagine what will it be like with the long tubes and and the rest of the higher setups we have!! I have raced a Porsche turbo aswell from rolling 40 nd beat it! If I ever get the chance to race any of these cars again I'll
make sure i put on video!!

hmmm interesting thing.. on my way home , I spotted a black Gtr after I merged on N405, I didn't act like crazy and cruise at 80 mph.. that black Gtr was about 70 mph but changed lane and started to accelerate. I changed to manual mod and downshift to 4th gear. At almost the same time. gtr just passed me and kept accelerating. I was curious to see how close I can follow that car,so I stepped on gas too.. supprising.. I caught up with him at about 120 mph (btw. it's jus straight line and no car around us).. maybe he didn't push too hard...
anyway.. we were both slow down and started to cruise at 80 mph again after that.. but it was fun ..my car has K1 and maybe rolling from 80 could help me a little...

Do the same with the GT-R and its running a 10.5 though. So tune for tune the GT-R is crazy fast!!
Still not as impressive as a Corvette though or a Viper. So calling it a super car is also giving it a bit to much hype. A C6 Z06 will run a 9.6 at 150MPH at 9psi. Now thats a supercar!
