Do you mean Autospeed on here or Zcar.com, or where? Will, you gotta turn off your computer, so you'll have time to do the stuff you need to get DONE! I loaned out my laptop once for a week, and you would NOT BELIEVE how much stuff I got done!

Thanks Will. I'll go look into it. also, thanks to TBK1 for the offer. I think it might be easier to just go with a c.a.i. system. Unfortunately, as much as I think about it, I just can't seem to think of a place that has high-pressure cool air, that's not in an awkward place, like the bottom of the windscreen (Will's favorite spot). I keep coming back to the idea of a cold air box above the engine, like muscle cars had.Again, the plumbing would be compromised with sharp corner(s). thx

It's meant to come off in case you hit it with your head, like in an accident.

NO, don't think my math is off. I used the wrong numbers. By going 186 MPH in the opposite direction of the Earth's rotation ( to an observer in space), your'e still going 700-186=514 MPH in the same direction, which agrees with your statement. To be going backward to our observer you need to be going 700+186=886 MPH in the opposite direction of the Earth's rotation. In addition, your statement about speed is correct. SPEED is only a magnitude, and VELOCITY has magnitude and direction. So if you use the word "velocity" while bragging about "speed" you need to include the "direction" (probably forward) to be correct. Ask any high-school physics student. Airplanes- I've litterally seen one fly off the ground with NO groundspeed. There was a sudden windstorm with gusts to 80 MPH. I can even attest to your other example by a friend of mine who hovered over a runway in an airplane (60 kt crosswind). thx

That depends on how you look at things. There's probably more pressure in front of the radiator, and behind the radiator support is less rain, which is why I think the tube was used. There probably isn't any one best place to get air, so you need a good filter to shed water and continuous fresh air. If you wanted to do a search on eBay, what words would you use? thx

Can you get the plastic Air duct tube that I see in the FSM for the 280Z? I think it might be good to have one because otherwise it's sucking hot air from the underside of the hood. Maybe you could even substitute something else. Other that that, trying to get cooler air to the intake system requires a ricer-type c.a.i. system. thx

I know there's a little fuel filter in the Injector at the top. I'm just a little confused, because there's supposed to be a rubber o-ring on the pintle end of the injector, and none of my injectors haved them. I've been looking at my FSM files, but it's slow reading. thx any way.

I'll get my 280Z up to 85 or so easy on the highway while passing traffic,so I would think I could get it up to 100 if I wanted to.

I had an interesting ride on my bicycle one day on a 100 mile tour of southern Ohio. I managed about 100 MPH on the bike downhill.

It doesn't look like a filter to me. Just a hard plastic thing with a little hole in it. The hole is smaller than the pintle even. I'll just clean it out with a little carb cleaner when I put the injectors back in.

Higuys, I sent Pallnet some money for a finned barb-rail today. And some socket-head injector bolts (one already stuck) Questions- I had an idea about mounting the new rail down the length of the intake, close to the injectors, keeping it low to the intake, with bent fuel hoses. (pic below) Can it be done? Also, I noticed there's a (plastic) insert in the head where the injector tip goes in. It's a snug fit. Do you have to replace those? I don't see them in any catalog. Is that the "o-ring?" There's a tiny little hole in it, so I expected a bigger hole. Now, I can either send out the injectors to get serviced, or just clean up the intake with some solvent & start reassembling things. thx Will- You going to post a pic of your rail ?

I'm sure they'll get much faster when they get electric technology perfected. As proof, look at the world speed record for electric r/c model boats, which is 122 MPH; gasoline- or nitro- powered models can barely reach 100 MPH. The next electric record race is for 140 MPH...

Right. You have me as an example of a perfect, highly-educated, intelligent person.

Do you think you could adapt this process to work with nuts & bolts? Something like a rock tumbler drum made of steel... thx

Why don't you wire yourself up and see what it's like?

Add to that there is no thing as decceleration, which is just negative acceleration. You can also throw in "centrifugal force," which doesn't exist!

I'm I'm "only" 75 miles from Mid-ohio racecourse, 50 miles from Dragway 42, 60 miles from Thompson Raceway Park and 40 miles from Norwalk dragway I think I'll go to the LeMans (May 20-22) and Vintage Grand Prix (June 24-26) at Mid-Ohio, but which car should I drive there? thx

Don't you get a headache from hitting yourself like that all the time?

Why are the raceways always so far from your house? seems like it. NOT the highways. :mad:

Then we are done here. Your calculations (however basic) are correct, but don't support the author's point. Actually, the dragster passed the corvette going at much more than the Corvette's 200 MPH, maybe like 350 MPH ( for example), with a final finish speed of over 500 MPH. Not the exact speeds, I would have to calculate them. Gives you an idea.

You guys are TOTALLY off the point. The average speed or the elapsed time has NOTHING to do with the example. The point being made is the the dragster can and DOES accelerate to such a speed that it catches the Corvette. Current NHRA, IHRA, or any other records have NO place here. I can make a similar point with a jogger and a cyclist. If you have a beef with the point, why don't you contact the person who originally put this fact on the Internet and argue with HIM. I have the mathematical proof right here on my table. You can calculate any kind of speed or time you like, but the dragster still catches the Corvette and passes it long BEFORE the finish line. thx

The dragster's finish speed is more like 300 MPH, so the average speed doesn't coount, and the dragster passes the Corvette at more than 200 MPH and finishes way ahead. Remember, the speed is measured during the last 66 feet of the way, so the dragster could still be accelerating or gaining. If the dragster averaged 202 MPH, then it would defintely need the whole track to catch the Corvette, in it even does.

The point in the example was that the T/F car accelerates to a much higher speed and thus passes the Corvette about 2/3 to the finish. The T/F car doesn't necessarily take 4.4 seconds to get to the finish, but you calculated the Corvette did. I graphed it real quick and at ~4.5 seconds the T/F car is going about 300 MPH (at the finish). I'd figure out the equation for it, if I could find my old physics book.

Thanks a lot, Mike Steven- If you assume the calculations are correct, the Corvette takes ~4.4 sec to go the 1/4, and the T/F car catches the Corvette in about 3 sec., then it would be ahead of the Corvette for the last ~1.4 sec., and sould finish way ahead.
