Bugatti Veyron engine.



And gearbox..May not be cool, but an amazing engineering achievement. 7-speed Dual Clutch DCT gearbox engineered and built by British company Ricardo.

I worked 2 summers ago at Ricardo MTC in Leamington, where these were made and tested, Every other week a man from germany would come down in a VW transporter and take 2 away on a pallet lol, apparently they were outstripping demand at 1 a week!

The DSG is a great concept, it has 2 clutches, and 2 sets of gears, 1,3,5 on one side, 2,4,6 on the other, the idea being that instead of shifting a dog clutch like usual, you just switch clutches, allowing for lightning quick changes. The box always has the next gear up or down ready to be engaged, so you can get shifts that are quicker than F1 'boxes.

A bump for this thread.

I was blowing up Russians on Battlefield in one of these earlier and remembered how much in awe' of them I am.

The Mil Mi-24 / Flying Tank / Satans Chariot / or Simply Hind

Insane Russian Cold War helicopter gunship, everyone should really read-up on it if you haven't already.






I always think it's the epitemy of the term "it's so ugly it's beautiful"
First time I saw one was in the Rambo movie and it was love at first sight. Apparently the blades and the rest of the heli can take .50 cal fire unscathed. Really, the only thing that brought them down were Stingers loaned by the CIA, and that'll bring down damn near everything.

Saw a Hind at leuchars in 2007 (i think), awesome experience!

Up close they are frighningly big and aggressive looking. I genuinly aspire to own one someday, even of it is non-air worthy.

The write-up on Wikipedia is actually pretty good and a very interesting read. The stories about what they learnt to do with them in Afganastan are astounding, apparently crews even learnt to do barrel roles.

Have another pic




Also some vids:

A little bit of artistic license fro 'Charliw Wilson war' but still good:

How to make one ugly helicopter into an even uglier helicopter. Still a mighty bit of kit.

The one in Rambo II wasn't a Mil Mi24 Hind but a Puma mocked up to look like a Hind A.

Actually close up they are far smaller than you might think.

Top Fuel facts'n'figures

  • One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Indy. 500. (about 6500hp)
  • Under full throttle, a Top Fuel dragster engine consumes 1 gallon 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 the 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).

Fascinating Top Fuel stuff...
Damn, that is some impressive info - never seen it for real, but on t'telly it looks like there's some damn large physics going on!! Can only imagine what it sounds like!! earscool

Out of interest; do you know why this was set quite some time a go? Change in regulations since then perhaps? Or was Mr Kalitta just particularly good?

They keep changing the rules to slow things down.

Is that a supercharger sat an inch away from where your bks would be?

If it is yikes and double yikes
