  1. Oops, that was a typo. If you see the explanation in the rest of my post you'll see what I was trying to say. I corrected the typo. I honestly think the swimming pool analogy I made is very easy to understand. I don't know why everyone thinks this is so complicated.
  2. As I said in my last post: This is not a problem similar to a person walking on a treadmill, because the wheels on the plane don't provide the forward motion, thrust from the engines does. Picture yourself in a pool, swimming laps. Your arms paddle through the water the same way the propeller pulls the plane forward. If you put a treadmill on the bottom of the pool (and turned it up to the speed you were swimming) would you stop moving through the pool? Even if you had wheels attached to your body that were riding on the treadmill? The answer is no. Now, could you put the plane on the treadmill, turn the treadmill up to 25 mph, and slowly increase the engine speed so that the plane didn't move? Well, yes. But the plane would barely be making any thrust and wouldn't be able to take off even if it weren't on the treadmill. (It would be like driving an automatic transmission car and taking your foot off the brake. The engine isn't making much power, but you roll) But the experiment was whether the plane would be able to take off normally if it was on a treadmill, and for that the answer is yes. Anyone who has taken high school physics should be able to draw a free-body diagram showing opposing forces. If you do that, the answer will be very clear.
  3. I don't think you understand the results of the experiment. The plane pulls itself through the air, so it doesn't matter what the wheels are doing, it's going to pull itself through the air at speed. It's like if you were swimming in a pool and someone put a treadmill on the bottom and ran it at the speed you were swimming. The threadmill doesn't matter.
  4. My position on this is the same as when this was first posted a year ago. The experiment is bogus because the airplane won't stay on the conveyor belt. An airplane produces thrust to pull itself through the air. It doesn't matter what the wheels under it are doing, it will pull itself through the air and off of the belt. Draw a free body diagram.
  5. The Acadia, Enclave, and Outlook get the best MPG in the segment. http://www.fueleconomy.gov/feg/byclass/Sport_Utility_Vehicle2007.shtml *They don't sort by the size, but compare them with anything else that's full size.
  6. Agreed. I would find some old tires and make body armor out of them.
  7. I was pretty sure the Hennessy SRT8 had a lot of work done to the motor. (head work) Spankis- yeah, a co-worker has a Jeep SRT8 and he was talking about some tuning issues. He also dis-likes the s/c kit.
  8. The engine between all of them is the same. I though there was a S/C kit out for the Jeep that put out pretty good HP on a stock motor...
  9. Honestly, I wouldn't buy it. The reorganization process can take a very long time, and in the end they could just dissolve the stock and start a new IPO. That's why it's so risky to buy a company in Chapter 11. Look at Delphi. Look at Ford. There are so many undervalued stocks out there right now that you should/could be putting your money into.
  10. With serious and/or fatal accidents they close the road down and measure everything, then reconstruct the accident. It's possible to estimate the vehicles speed pretty well based off the skid marks. It's not some guy eye-balling it, it's science and math. They know approx. how fast he was going.
  11. Well, talking on a cell phone is being outlawed all over the country. In Detoit and surrounding counties it's about a $125 fine, and it is being enforced. Street racing is illegal too, it carries a much larger fine, impound of your car, loss of license, and the police will enforce this as well. If you're talking on a cell phone and have an accident it's usually a minor to medium fender bender that's rarely fatal. Street racing is high speed and accidents frequently result in fatalities, especially when they're more than a 1 car accident. So no, I'm not buying your "cell phones are worse than street racing" argument. Racing is high speed and when you;re pushing a car to the limits you're counting on everything working perfectly, and that's just at the track. When you do it on the street you add in a ton more variables that are impossible to control, and the speed differential between the racers and other traffic is what makes it deadly.
  12. I also wanted to add that everytime you add a cam phasor you add a dimention to the graph, correct? The Z06 has no cam phasor (if I remember correctly), so it's 3D. The LS3 has one cam phasor that phases intake and exhaust together, so it's 4D. The Ecotec's have a two cam phasor's and independently phases intake and exhaust cams, bringing it up to 5D! How would you deal with this?
  13. I don't think you'll have trouble finding people to sign up for this.
  14. No, he got to drive the prototype and has an order for one, but they haven't even made their first production car yet. The handful that have been built so far were only for testing purposes.
  15. Selling it as a kit car was never an option for Tesla. They had to prove that the electric car was viable for production, meets all government standards, and went through a full product development and testing cycle. They're not on sale yet. They have been delayed due to transmission durability problems. On March 17th they start building one car per week, eventually ramping up to 40 cars per week. There are only 100 being made the first model year.
  16. Pulling a fuse always works, but if you pull the ABS pump fuse or the ECU's fuse you will have no ABS either. It you pull the steering angle sensor fuse (present in LX's) you will still have ABS. Not sure about the key turn to accessory, but if you turn the key to crank while driving over 20kph and wait a few seconds...
  17. Oh, and there are a lot easier ways (and free) to fully disable ESP, and it doesn't require any wiring or unplugging anything.
  18. Yeah, the Cherokee is the most fun of the SRT's, IMO. I drag raced one and he got me HARD on the launch. We were side by side until aero finally took over. I got by him around ~90 mph. Gas mileage sucks though. I took one up to 150 mph too. Cherokee Diesel is pimp though. Except it costs a lot.
  19. http://finance.yahoo.com/q/bc?s=USDEUR=X&t=1y The USD has been rebounding against the Euro, even though rates were cut at the end of last year. Satan - Spending is what people SHOULD be doing in order to stimulate the economy. But people should only be buying what they can afford, or else we stay in this giant credit mess.
  20. The AWD is nice to have on snow/slush covered roads, but for an Ohio winter you would probably never have to worry about it. We drive the RWD's in all the same weather as the AWD's (for winter testing) and 2WD will make the ESP system feel "tighter," so I don't think you'll regret a RWD.
  21. Why buy gold when the price is already inflated?? Mortgage rates loosely follow 1.7% above the 10 year treasury note, not the Fed interest rate. Keep you eye on that to know when it's time to lock in a good rate. It's pretty damn low right now, so if you can lock in 4.5% on a 30 year fixed I would do it, especially if you're up around 6 or 7+% right now.
  22. Don't forget the purple and burnt orange. I believe they have a little louder exhaust too. I drove a Sublime Green one for a few days and it's either love it, or hate it. Personally, I hated that color, but there were plenty of people that pulled up next to me and wanted to talk about it. I've driven all the SRT models, all the Hemi models, Hemi AWD's, 3.5L AWD's, 3.5L RWD's, and the dreaded 2.7L. The SRT's are a blast to drive, but they do suck a bit of gas. The newer Hemi's with MDS are a little better on gas, but I don't feel any of them get exceptional mileage. Both the Daytona and SRT models have a 0-60 timer on the dash and it saves your bet time. (That wins the coolest feature award in my book) The 2008's got a revised interior. I think it's a lot better.
