Past tense of 'steal' is 'stole', as in 'drive it like you stole it'. No 'd' sound at the end.
'Stoled' is not a word.
Nissan cracks down on illegal GT-R imports {Autoblog}
Dec 21st 2007 12:51PM What???
No one is stealing anything. These cars are bought from dealers in one country, and are then privately owned cars. They can be now sold as used cars by the owner. They are just selling them in a different country. No one is stealing anything. They are not coming out of the cars allocated for that other country.
You could argue that the new country's dealers don't make any money on the sale, but the same goes for ALL private party used car sales; somewhere a new car dealer missed a sale. New car dealers are in competition with ALL the other car sellers in the market, new and used, whether they like it or not.
The trademark claim must be over the use of Nissan logos, otherwise the ads should be just as legal as any other used car ad.
Nissan GT-R dynoed at 475 hp, 428 lb.-ft. of torque {Autoblog}
Dec 15th 2007 2:10AM Mike,
I think maybe you misunderstand what purpose a dyno is designed for. It is NOT to try to determine what a car's 1/4 mile or 0-60 will be, things where sidewall flex or tire rotational inertia come into play. Those are best determined in real life at a drag strip. The purpose of a dyno is to try and get the most accurate, repeatable power figure of the engine, as simply as possible. This allows you to test changes that you make to the engine accurately, with as little other factors as possible intruding.
At first this was done by strapping a car down onto rollers, but that introduces variables that you mentioned, sidewall flex, etc., that DETRACT from the accuracy of the engine power reading, not improve it.
The next step is a dyno that attaches to the hub as discussed here, which removes these variables that can vary from run to run on the same car, interfering with getting an accurate, repeatable engine power reading. Yes, you could remove more variables by hooking the dyno up to a driveshaft, or by removing the engine and testing it directly. However, these steps introduce extra costs and difficulties, and do not do very much to improve the repeatability of the results.
A dyno works by timing how fast a car's engine can spin a known mass up to speed and calculating it's power using that time and mass. Adding the unknown friction and mass of non-driven wheels to a dyno would only worsen the accuracy of the calculation that determines the car's power, not improve it.

Dec 15th 2007 12:19AM @Poopy Head :
If you had slightly more ability in the reading comprehension department, you would understand that I was laughing at the remark that there was a "loss between the hubs and wheels", (which shows a lack of understanding of mechanics and physics), and that I never mentioned anything about tires. The miniscule lack of the extra rotational inertia of wheels, when one is already considering the rotational inertia of the rest of the drivetrain, does still not constitute a "loss between the hubs and wheels". The only thing that your comments on the subject show is that you are immature, similarly lack a basic understanding of physics and mechanics, and still like to use 'potty words'. Thanks for the information, come back when you've grown up.

SEMA 2007: '34 Chevrolet Coupe E85 {Autoblog}
Oct 29th 2007 1:15PM From damon's summary: "35-inch Excelsior rear wheels partnered with 29-inch rollers up front".
I was thinking that the car must be a lot bigger than it looked because those huge wheels looked well balanced with the car. Then I read in the press release:
"The tires are mounted on custom 18-inch front and 20-inch rear "kidney bean"-style wheels from Budnik."
Shouldn't an Autoblog editor know the difference between wheels and tires?
