Default Go Karts

How do electric indoor go carts compare to outdoor racing go-carts in terms
of top speed and take off acceleration. A friend went to an indoor racing
go-cart place and thinks they are way faster than any gasoline powered
go-cart, I think gasoline must be faster. Any online comparisons?
Thanks for settling our argument.

"Vol 6, Issue 1, 2005 Issue: The Electric Car

The Electric Car: What Does the Future Hold?
The electric car is back, with a new lithium-ion battery, 300 mile
range, the power to out-accelerate a Ferrari, and the ability to plug in
to any power outlet. We look at the achievements in technology from AC
Propulsion, and examine the pitfalls of the proposed hydrogen economy of
the future."


I have the magazine and the electric car out accelerates the Ferrari,
Porche, Corvette, and another car, all in the 1/8th mile.

--Last time I looked folks were powering electric gokarts with
Lemco motors; these have fairly awesome power in a small package. The
kicker isn't motors anymore but batteries: how much are you willing to
spend? NiMH are good but you gotta be careful charging them.. Li-Ion, I'm
told, is a superior technology and cheaper to make, but as it's new they
still cost more than NiMH. OTOH either one will beat the socks off of
NiCads..

Electric motors have way more torque at low RPM than IC engines.

If you know someone who owns a Prius, ask for a demonstration. Quite
impressive!

Actually, these hole shot gokarts are using Ultra capacitors to give it
the few seconds of kick needed.

I looked at a few websites and have seen some 125cc gasoline karts capable
of 125+ mph and the fastest electric were only capable of 40+ mph.

A 250cc Super Kart is faster than that. The ones I've seen run at local
tracks (Sears and Laguna) typically run times on par with Trans Am cars.

Lane,

Doesn't look real to me, I've driven a Viper.

If that guy was really on it there'd be so much tire smoke it'd look like
the back end was on fire. Even on a tacked up surface you'd still get a ton
of smoke with those tires.

Maybe, you ever see how much smoke a top fuel dragster leaves when it is
hooked up and going, not doing a burn-out???

The Viper is geared to run 190+ mph... but only hits 118 - 120 mph in
the 1/4 mile. If you geared the Viper down to run fast 1/4 mile times... it
would stomp that little golf cart like a narc at a biker ralleye!
That thing is a joke (compared to the Viper).
Add 5 mph bumpers, air conditioning, and enough batteries to match the
Viper's 350 mile cruising range... and it's a super-joke.
Charge the batteries with power from a coal or gas-fired powerplant...
and it's a mega-joke!!!! LOL
Typical media stunt... trying to make "alternative" vehicles appear
"competitive" with conventional vehicles.

Cliff,

Yep,,, and that has everything to do with the special tires, surface, and a
few other very unique factors.

That Viper had stock tires, It'd smoke like hell.

You don't want smoke. Smoke means wasted HP! The torque/power isn't getting
transfered to the pavement, but rather burning up the tires.

Lane,

So you run the Viper at half throttle ??? Sorry man, Your gonna get about
100 ft of smoke with that car on plain pavement with stock tires. Besides,
it doesn't even look like he's on it. Been der,done dat, it's fake.

Not a media stunt at all. There are those that race electric vehicles all
the time. It is just what they like doing, just like people here like metal
working.

Look at some of these records; http://www.nedra.com/record_holders.html

Or the World's Quickest & Fastest 'Street Legal Electric Car' at:
http://www.austinev.org/evalbum/035.html

Or the fastest Electric dragster, 0-60 in 1.5 secs;
http://www.phoenixeaa.com/photoalbum...ube1/main.html

I'm not saying that an electric car is for everyone, especially one that is
designed to race. I just find it fasinating what is being done with them. I
wouldn't mind building my own little electric to commute to work with and
make runs into town. I wouldn't need more than a 30 mile range. I drove a
Geo Metro once that was converted. What fun that was. No noise, lots of
getup & go and very smooth.

OK I see you're going to be hard to convice, try these.

Here is another electic vehicle drag racing another viper. Terrible video
quality however.
http://www.electrifyingtimes.com/elect_2_old.ram

From: http://www.peakoil.com/fortopic8987.html
"Electric Datsun 1200 barely got defeated by a Viper, however he blew a
battery. Named "White Zombie" driven by John Wayland". It has routinely
dusted off Vipers in the past. At the time of this race, it was powered by a
single Kostov 11'' series DC motor and a 1400 amp Zilla controller:

Electric motors can and regularly do provide tremendous sustained torque
for vehicles. After all, the "diesel" locomotives, "diesel" quarry dump
trucks and 'nuclear' submarines are all driven by electric motors. Those
applications work because there is a diesel or nuclear genset providing
the power for the motors.

The problem is that current battery technology is still crap for power
density and cost so an "electric" vehicle relying on batteries still has
very poor overall performance. An electric vehicle "sprinting" may be
amusing, but it would fall flat in a "marathon".
