E-Dragsters Go for Gas-Powered Records

With Barely a Sound, Electric Dragsters Aim for Gas-Powered Records

PORTLAND, Ore. (AP) -- Straddling a 619-pound motorcycle, Scotty Pollacheck tucks in his knees and lowers his head as he waits for the green light. When he revs the engine, there's no roar. The bike moves so fast that within seconds all that's visible is a faint red taillight melting in the distance.

Pollacheck crosses the quarter-mile marker doing 156 mph; he's traveled 1,320 feet in 8.22 seconds, faster than any of the gas-powered cars, trucks or motorcycles that have raced in the drag sprints on this weekend at Portland International Raceway.

It's particularly impressive given Pollacheck is riding a vehicle that uses no gasoline and is powered entirely by lithium-ion batteries.

From article:”If you have a car that is faster than everyone else’s, if it’s electric so be it, but people will buy it.”

That is the truth, especially in the USA.

That’s KillaCycle?

Given that electric motors achieve 100% horsepower at initiation, you’d think they would have a bigger chain (or possibly shaft drive). Titanium-alloy racing chain?

from the article .... very interesting

In December, the KillaCycle will receive a second-generation battery pack that will have twice as much juice as its current 374-volt system, giving it close to 1,000 horsepower. Fulop said he believes the KillaCycle can break the drag racing motorcycle record within the next year.

Electric drag racers are test-driving the technology that will eventually spill over into mass production cars, analysts say.

Today's hybrid cars, like Toyota Motor Corp.'s Prius, use nickel metal hydride batteries, which cost less than lithium-ion batteries.

But the price of lithium-ion is expected to drop. In addition, the latest generation of batteries offers a higher rate of conductivity and takes less time to charge -- the KillaCycle's battery pack can be juiced up in five minutes. New materials also mean the battery is less prone to overheating and explosions -- a danger of earlier generations.

Experts say lithium-ion batteries that will power a car tens of thousands of miles over their lifetime and deliver more horsepower are on the horizon.

What?

Horsepower equals Torque times RPM.

It is not as expensive as you seem to think.
From:
http://www.arb.ca.gov/msprog/zevprog/factsheets/evinformation.pdf
it appears that an Electric Vehicle costs about $1 a day. which is about the cost of running a 60 watt light bulb for 24 hours.

I don't see anything wrong with the question about the chain. My bikes have 520-530 and this drag chain is a whole lot fatter than that.

Chains, however, are more efficient than shaft drive gears (if properly tensioned), so you wouldn't see the designer specify a shaft.

I think it is properly stated that torque is flat throughout the powerband.

“will power a car tens of thousands of miles”

So every two years or so I have to replace the batteries? That does not sound cheap.

My scooter has 2 55 amp batteries and can go 12 miles between charges. That is at 6 mph and with my weight on board.
I can see this thing doing a 1/4 mile easily at this speeds.

You would have to put fully charged batteries in it every time for peak performance.

"Just proved that you know nothing about traction and racing slicks."

From his post it is clear he is talking about energy transfer from the motor to the wheel and not, as you thought, about energy transfer from the wheel to the ground. So, traction and tires do not come into it, yet…

Before you try to belittle someone’s post, make sure you understand it first.

If they compare to the cost of rechargeable batteries for portable drills, saws, etc.; the replacement costs are going to be berrry berrry ‘spensive.

Yeah,obviously they`d have no chance against a
Pro Stock bike,but it`d be interesting if NHRA would
give them their own class if there was enough interest.

NHRA going green,would be interesting.

Horsepower equals Torque times RPM.
********************************
Sure does ,, but what I think he was getting at was that the power of an electric motor is more or less linear ,, no curve just a straight line , you have the same torque per hundred rpm at barely running and at 10k.

Just think how easy dialing in that rocket is... keeping it just below the traction threshold.

Watch the video of this beast do a burn-out and subsequent speed run. It is wild! And the sound. It sounds like the largest, meanest, most dangerous mosquito in the universe. Like anything taken to extremes, its just too cool.

I don't see anything really unusual in the technology as it is applied. Most of the really powerful movers in the world are electrically powered. Examples: Cruise ships (diesel turbine electrical generation powering electric motors in pods); any nuclear powered ships, locomotives (diesel-electric) and large earth movers (Liebherr T 282B). Therefore its no surprise that somebody has made the jump to raw speed and power in an electric drag-racer.
