R&T Redux by lemmer

There is a small firestorm going on in the R&T forums with some heavy allegations of sandbagging on the part of Millen. Based on all of the objective performance data, the other lap times sure seem a little slow in comparison to the GT-R. It doesn't help that he has links to the article on his website and states his company has big plans for this car. It seems like a substantial conflict of interest.

You'd think R&T would have thought that through ahead of time. But allegations don't prove or disprove either side. I've seen plenty of loyalist excuses so far, and this potential conflict of interest just gives them ammunition.
 
However, there is still no evidence to suggest that the GT-R would not be faster than these 2 cars on a track, from any source.
 
The degree to which it is faster will have something to do with driver ability and familiarity with the vehicles. Professionals with the GT-R (and Millen is no exception) have come close to Enzo times on tracks already. So were the previous drivers in the Enzo 'sandbagging' so that a year later the GT-R might catch up? Not likely.
 
Even if all 3 were exactly the same speed, the fact that the GT-R can even accomplish that despite being significantly heavier already proves that the other 2 have untapped potential. They technically should be performing better than they are.
 
Its not the driver's fault if the 911T and Z06 can't catch an Enzo. That's Porsche and Chevy's fault, and it might just be physically impossible to do. If a driver in a GT-R can catch an Enzo.... well done Nissan.

Do you think ANY of these cars, showroom stock, could possibly sustain speeds over 175 mph for any length of time without hand-grenading? These speeds seem somewhat irrelevant to the real world.
 
The reason I see a bright future for the GT-R, and the reason I see it as ground-breaking, is that the platform seems to have a great deal of room for development, whereas cars like the Viper and Vette need to be re-invented for the future IMO.

I noticed the Nissan didn't dare go up against an 08 Viper ACR. With no cupholders you'd think the Viper wouldn't stand a chance but who knows.
 
Some of these magazine tests should be required to put a disclaimer at the start of the article on how much ad revenue each of the manufacturers in the test contributed.

Give it time. The Viper ACR might be more in the same category as the lightened, strengthened GT-R Spec.-V. But it might be a while before we see those 2 go head-to-head in a test.

Similarly I said a few weeks ago, that it would be interesting to run these cars at a track like Indy, Daytona, or Talladega for 24 hours. See how many miles they can run. In that case you would be including mpg, gearing, cooling design, tire wear, and whether your design to achieve high power is really reliable. I would think in a test like this displacement would matter (less stressed, more cooling area), with a car like the Vette or Viper running the most miles. I know Saab used to tout this type of test (24 hour high-speed run) about 10 years ago in their advertising.

Basically, what you're suggesting is drive them both until they handgrenade? And even then, which one goes first might vary based on certain conditions. So what we really have to do is buy 10 of each and then average which one blew up after how long. But who has a spare million to prove this moot point?
 
I think the point that was being made is that NEITHER is durable enough to take that kind of punishment.
 
Similarly to before, this really isn't the practical kind of test that can determine a real winner between these cars in stock form.
 
Also, its not as simple as displacement. Endurance-race prepped Corvettes and 911s match up quite well. The extra cooling of the larger block is partially counteracted by the extra friction that having extra pistons invariably causes. Displacement is not really the measure I would use to predict a winner.

Race engines actually are more "fragile" than a stock engine, as they usually run higher compressions and rpm. I would fully expect a large normally aspirated engine to run for 24+ hours at an rpm a few hundred under red-line, especially with a synthetic oil.
Mazda did it here with a very small displacement engine:
http://www.seriouswheels.com/cars/top-2004-Mazda-RX-8-Record-Run.htm
 
If you do some searches you'll probably find other manufacturers do this with their cars, with various changes.
 
Or maybe more impressive: http://www.saabhistory.com/2007/01/25/the-last-saab-9000-503087/
"The ‘Long Run‘ endurance test on the Saab 9000 at the Alabama International Speedway in Talladega, Alabama, U.S.A. in October 1986 played a major role in strengthening the sporty image of the car. Over a period of 20 days, Saab staged an incredible record run with three standard production Saab 9000 Turbo cars. This resulted in 21 new international records and two world records - the foremost of which was a distance of 100 000 km at an average speed of 213.299 km."
 
I would be quite upset if I paid $70K+ for a high performance car, and if it was only good to run for 20 min. or so at a time! I would expect these cars to be able to run 150mph+ for their full warranty period. Otherwise since you're bound by the laws on the road, you might as well get an Accord V-6.
