Let the authenticity debates begin...
Speed-o's are notoriously inaccurate things, esp. at 200+ MPH
Very impressive acceleration though, wish my 6 pulled like that :twisted:
Interesting footnote: An 05 GSXR1000 is not only faster that an 05 GSXR1300 it also gets there quicker
OMG, 140mph on the back wheel.
I personally haven't been anywhere near the 200kmph speed let alone 300kmph on a m/cycle and therefore cannot judge authenticity but I would have thought that the white lines would have appeared to have been going past you faster than what they were in the vid.
I think 'Ghostrider' pulls off a 200MPH wheelie on a turbo Busa!
220 mph is nearly 100m a second. I've been at nearly 230 mph in an Ultima GTR (If you have the means, I highly recommend picking one up) and that video doesn't look fast enough. That said it's hard to say with a camera because you don't get that wide angle and fish eye effect the eye gives.
Considering the power that can be pulled from a Busa I'll say that it's definitely plausable.
230mph = approx 370kmh
let me see
thats quicker than an F1 car (tops at 350-360kmh)
a V8 Supercar (tops around 300)
a MotoGP bike (340kmh)
He must have had the wind behind him then....
Pretty sure that's what they were claiming and it's certainly what the Motec was reading.
Had a sit in one at a show day at the Ultima factory in Hinckley and an airfield they were using as a test track. Went with my ex-boss who's a car nut with quite a list of cars that he owns or has owned and they offered to take us for a spin around the runways.
They're a pretty insane machine. Weighs 990 kg, 0 - 100MPH - 0 in 9.9 seconds.
The Ultima GTR does have a top speed of 230mph which is why it's currently considered to be the fastest production car available. It's what happens when you put a 534bhp 6.3L chevy engine into a 990kg car.
230 mph, is that all :?:
Wasn't there a car that could top that 10 years ago F1
Anyway, I thought we were talking 2-wheels here :?:
Top speed for a motogp bike was 356kmph; Loris Capirossi preseason testing mugello 2005
Fastest during racing 337.1kmph; Careless Chucka Mugello 2005
the top fuel dragsters can do 330 mph (530 km/h), THAT would be scary... and they get the front wheels up too!
The real scary thing about top fuelers is the acceleration from the line.
Speed I can deal with but 0 - 100 in 0.5 - 0.75 of a second, 0 - 500 in a touch less then 5 seconds...
My mates Across (man bag) can do that.......
Dumping big output donks into light bodies doesn’t necessarily equal high top speeds.
High power to weight ratios will ensure high acceleration, but when chasing top end its more to do with final drive ratios and aerodynamics.
and thats within 400m..
There was some interesting info on drag racers going around on email a while back:
*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 1 1/2 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 measure 7050 degrees F.
*Nitromethane burns yellow. The spectacular white flame seen above the stacks at night if 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 mph 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 per second. The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile (10/5/03, Tony Schumacher.) The top speed record is 333.00 mph (533 km/h) as measured over the last 66' of the run (9/28/03 Doug Kalitta.)
Putting all this into perspective:
You are riding the average $250,000 Honda Moto GP 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 the throttle hard open, 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.
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.
Almost makes the bike seem slow don't it
Oh, a car. And here was me thinking that's one hotted up Kawasaki tourer.
Indeed. The efficiency (on a cubes to hp basis) is actually pretty good. 500 cu for around a lazy 8000 bhp. That's nearly 1hp for every cc. Mind you when you can get fuel flow of up around 5.7 litres a second I guess that's to be expected.
I think it's now clear what the bike world must do to compete. Bring on the 1000bhp litre bike.
The triumph drag bike of Jay Upton is putting out around 1200bhp from 1400cc so they're not too far off.
