  1. Dunno if any one has seen this already but its worth reading. One for the rev heads.......... Read on.......... A lesson in acceleration: ------------------------------------ First, some useful info: * One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. * Under full throttle, a Top Fuel dragster engine consumes 1½ gallons of nitromethane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced. * A stock Dodge 426 Hemi V8 engine cannot produce enough power to drive the dragster's supercharger. * With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders run on the verge of hydraulic lock at full throttle. * At the stoichiometric 1.7:1 air/fuel mixture for nitromethane the flame front temperature measures 7050 degrees F. * Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases. * Dual magnetos supply 44 amps to each spark plug. This is the output of an arc welder in each cylinder. * Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow. * If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half. * In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. In order to reach 200 mph well before half-track, the launch acceleration approaches 8G's. * Dragsters reach over 300 miles per hour before you have completed reading this sentence. * Top Fuel Engines turn approximately 540 revolutions from light to light! * Including the burnout the engine must only survive 900 revolutions under load. * The red-line is actually quite high at 9500 rpm. * The Bottom Line; Assuming all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs an estimated $1,000.00 per second. The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile (10/05/03, Tony Schumacher). The top speed record is 333.00 mph (533 km/h) as measured over the last 66' of the run (09/28/03 Doug Kalitta). Putting all of this into perspective: You are riding the average $250,000 Honda MotoGP bike. Over a mile up the road, a Top Fuel dragster is staged and ready to launch down a quarter mile strip as you pass. You have the advantage of a flying start. You run the RC211V hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph (293 ft/sec). The 'tree' goes green for both of you at that moment. The dragster launches and starts after you. You keep your wrist cranked hard, but you hear an incredibly brutal whine that sears your eardrums and within 3 seconds the dragster catches and passes you. He beats you to the finish line, a quarter mile away from where you just passed him. Think about it, from a standing start, the dragster had spotted you 200 mph and not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race course. That, folks, is acceleration. Cheers Alan
  2. use the bolt that holds your back seat down to mount the bracket. There is a bolt on both sides of the car in the back,near where your feet go
  3. While waiting for the lanyards guys you can achieve the same effect by tying a couple of footyboot laces together
  4. The ad says that there is nothing like this in Australia, yet there is one of these cars in the workshop where my son works (Springvale) as I write this. Great looking car.

    Home car wash!

    I've got a Karcher 520 and its great on the cars.Especially good for getting brake dust off alloy rims.
  6. Great thinking mate. Look how many views you've had for the ammount of time the thread has been posted.
  7. Welcome to the forum mate. 450 bhp is about 335 kw. Look here. http://www.onlineconversion.com/power.htm Alan
  8. I havent seen Ed since he, Al, Max and myself went on a cruise to the island last year
  9. Pic sent mate.Your idea is as good as mine about the price of the other 2 tyres Alan The email I sent you returned to me. Either you gave me the wrong address or your hotmail inbox is full

    .

    I know its a difficult time but hang in there mate. I know how you feel but in time you'll feel better Alan
  11. I think they're Work rims (because thats whats stamped on the inside of them) and they are 2 piece. In good condition. Tyres are 2 x Sumitomo 235/45z/r17 about 90% rubber 2 x Silverstone Sport 235/45z/r17 not much rubber I had them on my R33GTR with about 5 or 6 mm spacers. Dont ask me what else they will fit beacause I have no f***ing idea I've got no idea of how to make the pics small enough to post on here so my email address is [email protected] PRICE DROP $900 ono Carn guys get em out of my garage Phone 0413609185 pics added look below
  12. Yeah a lot of them are dickheads Mark as I deal with them every day. At least you're ok.
  13. PM dave on the forum. he got mine Alan
  14. Yeah thats probably the same order I'd use them as well. Ultimate is probably more difficult to locate but only optimax if I cant find the other two
