Sigh..........yes more magazine racing

I really dont understand all the crap with the 0-150 times. Basically the GTR from 0-120(whatever it traps at in the 1/4) beats the cars mentioned but from 120-150 slows down, gets slower and gets over taken. Something doesnt make sense. Its that 30mph window and weight at that speed is not as much of a factor as it is when you are accelerating from a stand still.

I can understand the autobahn bomber(porsche) over taking the GTR at higher speeds(160+) because traditionally german cars have been geared better for those high autobahn speeds but to beat the GTR by that much in a 30mph window when the GTR has already beat it from 0-120........

So again from 120mph to 150mph going by mag test the GTR is getting crushed?

 

We just need to find another magazine...

 

nevermind.

 

Against which cars? Definitely not the Z06, and the GTR still is a relatively heavy car with no real hp advantage.

 

I ran my GT-R (475 awhp SAE) vs my ACR (563 rwhp SAE) from a 40-140 MPH roll, the ACR did pull by about 2 cars, but I was surprised how well the GT-R did given the less horsepower and more weight....

from a dead stop it would be very tough to catch the GT-R in the ACR or most other high HP RWD cars.....

 

what does a ACR run in a 60-130? was it behind by only 2 cars all th way till 140? if yes thats impressive. I will be running my friends stock GTR vs my 500awhp car this week , i will let you know the results. Or how many cars i beat the GTR by.

 

ACR isn't a roll race car, its a track terror. A stock Viper would actually be better for roll racing because it has less downforce. The ACR loses almost 30 mph of top speed due to the downforce.

My question is have you ran the cars on a track, now that is something that would be alot of fun!

 

I agree with you, my wife could launch the GTR within a 10th of the pros. It takes a real good driver to launch a powerful RWD car correctly, but it would get nasty real quick if you ran into a stock Z06 on a drag radial. Which would be common if you live in Texas, LOL.

 

Who knew the GTR would be this fast? I thought they were stuck around 12.5.....

 

for top speed runs probably, but up to 150 MPH, it will roll VERY well, the car pulls very hard... ACR's have trapped 129-130 MPH stock in the 1/4 mile, with and without the rear wing on....

I have had the ACR at the track, but not the GT-R....

 

good luck. The big advantage the GTR has is the transmission. it does not loose boost between shifts so if you take two cars with the exact same power and one has a hard shifting automatic and the other has a manual, you will loose by a lot. The auto car will pull ahead by a car length on every shift. at the quarter there will be a full half second difference in the cars, yet they have the same power. That is how the GTR goes so fast. If it was a manual transmission it would probably be a lot slower and get creamed by most cars out there due to it's weight. That $20k transmission does a good job. Nissan spent the money on putting the power down right.

So if your buddy's GTR is totally stock, say 410 or so awhp, I predict you will not beat him by much. Maybe a car length, even though you have 90 whp more and weigh 400lbs less. your manual trans slows you down between shifts, if you are a great driver then that may be a different story. There are people that can shift a manual transmission as fast as an auto.

 

Even those who can powershift, interrupt the power to the wheels briefly. The DSG already has the next gear preselected and the power interruption is either very , very small or non existent.

So did your Viper have traction problems at 40 mph and was the GTR brake boosted at the beginning? I am having a hard time with two cars trapping between 9 and 10 mph different being so close to 140 mph.

The many you tube and street fire races between the Z06 and the GTR show it pulling the GTR pretty hard from a roll. Especially on the top end above 100 mph.

 

Not true. pure and simple. Stock GTR can run only a 11 sec 60-130. That is really slow by any standards. A cobb tuned GTR with mid pipes ran a 9.89sec 60-130. My car runs low 7 sec 60-130.

Either way you look at it ...after driving my friends GTR i feel its a fast car until 90 ish...after that it hits a flat spot and feels really slow even compared to my tuned 335i.

My prediction is he will be destroyed so bad (5 + car lengths)...no comparison. #'s speak for themselves.

Just browse below and read the files. GTR with cobb tune and mid pipes is still way slower...its in the 9.89 sec range.

Basically when compared to the slowest 996tt which did 7.29 sec (mine should do flat 7 sec)...when the 996tt is at 130 GTR is barely breaking 115mph.

when it the 996tt is at 100 in 3.2 sec...GTR does the same 100 in 4.5 sec.

so the bottomline ...a GTR which does low 11 sec and 123 trap..still hits a wall after 100.

And for the guys comparing a c6 z06 to a stock GTR...come on guys...its not even close, z06 is a monster and just put a tune and intake it will pull most cars. All my data is for 60-130 and nothing else.

I will have vids on by the end of this week.

 

the problem I have with your theory is the 117 to 125 mph trap speeds the stock GTR's are pushing. I cannot imagine that a GTR would be that slow to 130, when it is trapping high teens low 120's in the 1/4 mile. But we'll see. If you do a 60-130 then you negate the better launch potential of the GTR and you take out 2 shifts which will keep you in the running, but from a dead standstill and 3-4 shifts to the quarter you will loose time on every shift. you may not loose enough time to loose the race, but it will definitely slow you down. Do a run to 130 from a standstill and lets see what happens. you should win, but I don't think your going to win by as much as you think you will.

 

You take out the launch and gearing advantage and the GTR is a relatively heavy car with less power than the 997 Turbo or Z06. Which is why both pull the GTR over about 90 mph.

That's why I think from 40-140 the huge power difference between a 120 mph trapping car and a 129-130 trapping car should equal more than two cars. But I wasn't there and don't own both cars, I would imagine the Viper to be traction limited from a low roll.

The guy I know that has a GTR with the HKS 570 mods and more walked his customers ZR-1. But the told me on the factory PS2's that the car would even lose traction at 70 mph.....
