Hi Grayfoot,
The front wheel is not a load bearing wheel, and does not steer in any
way, it has very little effect on the car on or off the ground.
If you study controllers you will find a comtroller will not stay on more
than milliseconds if the pulse width modulator shorts out.The car also has
a very low center of gravity, very hard to tip over.

Tom,
The polite request for info went misunderstood. This one's a bit more
gruff.
So, when going down the road at 60 MPH and a stiff headwind comes
along while your front end is slightly off the ground you've designed
the car to fly in a stable manner?
Motor going out is not my concern. When a Controller goes out is what
I want to know about. What happens when, as you're going down the
road at a reasonable speed, one of the motors suddenly goes to full
power because the controller failed in a shorted condition. My guess
is you end up on your top after the car tries to do a 90 degree turn
at speed.
What is your stopping distance under emergency conditions? How
straight does it drive with the brakes locked? Can you insure that
one brake will not lock before the other in real life panic braking?
I've driven tractors with the brakes and it's not the most natural way
to control a moving vehicle.
You cut up a multi-hundred-thousand dollar car to make your Electric
vehicle out of??
Gruff mode out...
Honestly, I would have extreme concerns about someone driving that car
around me. Also, while I'd love to give it a spin I wouldn't want to
do so in traffic!

Some more points in favor of Fieros:
-- cheap
-- tough drivetrain, people put V8 motors in them
-- one of the few cars with a space frame, like a race car
-- very safe (best frontal crash test when it was out)
-- kits to make them look like Ferraris
-- fairly light (2350 to 2700 lbs, but alot of weight to remove)
-- lowest highway power of any car then per the EPA database
-- great mid-engined handling
-- great braking
-- great legroom
-- plastic body
-- huge central tunnel a good place for batteries
and some bad points:
-- orphan car, not made any more
-- handbrake cable tends to seize
-- cable shifter is not precise
-- soft motor mounts let the motor rock too much

There are a number of electric fieros if you scan the evalbum.
They make really good EVs in my opinion. They are small and relatively
light yet have a beefy suspension and brakes, unlike other small cars of
similiar weight, and has a fairly heavy engine to remove.
And lots of room outside the passenger compartment for batteries.
And manual steering. I'd really like is to have manual brakes for mine
also to avoid the vaccum pump, so if any other Fiero owners might have
input on that I'd appreciate it.
I've got a contact controller setup in it right now.

I guess pulses can mean something different. But with
sinusoidal AC, a single phase 2 pole motor has a
pulsating magnetic field at 2 times frequency
(rotation), once north and once south. But a balanced
3 phase machine has a rotating magnetic field, which
at a fixed point on the stator sees one north and one
south pole pass per cycle. This is due to the vector
sum of the three MMF waves displaced 120 degrees.
This is why 3 phase induction motors will start on
their own and single phase induction motors are not
inherently self-starting.

That's a good plan. I did exactly this on my Elec-Trak. Unfortunately, I
didn't think to do it on my LeCar EV :-(

I don't think it matters much. But if it worries you,
check with your motor vendor. I guess it boils down

I'd have to agree with John, I have a light weight VW
bug (lots of fiberglass parts and 10 12 v orbitals. I
barely get 15 miles between charges. We all need to
be very realistic when we talk about range. Unless
this guys trips are all downhill there is no way he
gets 50 mi per charge.
Second that, Keith!
My Jetta, doesn't do THAT well, with 1200 lbs of Badd-eries aboard My 101
mile range record with the Rabbit was done with a few 110 volt 15 amp
charges along the way for an hour here, an hour there, sorta thing.Like if
you wre running errands in it. BEFORE I got my PFC 20, done with a variac,
charging. So I don't brag much about a "100 mile range Rabbit" A solid 50
mile depend on it range was a better claim, and this was with Trojan T
145's an Awesome batttery!In Portland's hills I don't think I would get even
50miles, IF driven, keeping up with traffic. But in Phoenix AZ or Wrong
Island NY I could handily get 75 mpc Flat as a table top!Or FLA? No wonder
the FLA EAA is going so well, PERFECT place for EV's!
EV Range claims? Hah! Been hearing them for 40 years, as well as the
Miricle Battery, charges in an hour from ANY 120 volt outlet, will run a car
300 miles at 60 MPH.Check out old Pop Sci Mags! Not holding my breath, but
nowadaze it COULD be possable, with A 123's, Fireflys and other dark horses
running , now, in the battery sweepstakes.
It is now true to say EV's Problems aren't technical, but Political. We

Not sure what you mean by "power of 12 volts".
The J150 or T1275 appears to be an option with very good potential for
anyone considering using a flooded 12V battery. They should be far more
durable than the typical 12V flooded marine/trolling batteries that
people usually end up using in this case.
I expect it will have similar [low] power as a flooded 6VGC or 8VGC
since it is simply a rearrangement of a similar number of similar plates
to give a battery with 2x the voltage and 1/2 the capacity. The
advantage it offers for someone wanting the forgiving nature of floodies
is the ability to build a much lighter EV for a given voltage, or to use
a much higher voltage flooded pack than is usually practical with
flooded 6V modules.
If you want an EV with the "power of 12 volts", Optimas, Orbitals, or
Hawkers are still the lead acid batteries of choice... ;^>
Cheers,
Roger.

Hi EVerybody;
Nature's most perfect differential!! Worked beautifully in my early
Electro Liner daze 40 years ago. Two golf cart motors, one for each rear
wheel! Bob Beaumont took a page from my book with the Tropica. Too bad THAT
didn't take off! Always thought it was a goos system, but alota unsprung
weight having the motors mounted on the rear axle. But Electro Liner One was
not a high performance vehicle. Today it would be called an NEV!

ahhh... something i know about.
almost all bike computers have a remote sensor that reads the signal from a
magnet mounted to a spoke on the wheel (for speed). higher end computers may
also have an additional sensor to read pedaling cadence, detecting a magnet
mounted to a crankarm.
most computers can be calibrated to work with a wide range of wheel
diameters, and as long as you can get the fixed sensor mounted within half
an inch or so of the wheel on which the magnet is located, you should be
able to get an accurate speed readout.
i'm not sure if the cadence sensor, or more specifically the computer's
display, will handle the rpm values that you can expect in a typical EV's
electric motor though, so using the cadence function for an rpm display may
not work.
i recommend using a wired, as opposed to wireless, computer in any EV. i
love wireless computers on my bike, they're incredible. however, there's
simply too much metal on an EV to get a reliable signal from the sensor to
the head unit. the sensor transmitter just isn't strong enough.
we sell a lot of computers here...
http://www.speedgoat.com/catalog.asp?cat=120
i recommend cateye or vetta. they're simple, cheap, and reliable.
another option would be to look at GPS units for speedo, etc. although
Speedgoat sells some cycle-specific Garmin units, i don't think they would
be as effective as some automotive-specific GPS units.
feel free to ask any questions about bike computers in general, or certain
models specifically.

How about an inertia switch?
Ford has these on their cars, I think. You hit something it turns the
car off. I think the Tour de Sol cars had to have these but can't
recall and anyone get easily get one.
I opened one up years ago. I think it had a ball bearing or something
inside that would release upon impact and strike a relay. It was
mounted under the dash on the firewall. It's all a 12 volt affair so
it would be just like any other relay in series with the key switch.
I think it's on the Electric Ford Ranger, but I'm sure you can get
them somewhere.
These folks are going overboard on the safety issue as far as an
emergency kill switch. Are they going to require the same thing on OEMs.
Granted we do at NEDRA but even the gassers have to have an emergency
cut off switch on the back.

Subject: Re: Zilla emergency shutdown
Hi Dave;
Didn't the State want a Kill button OUTSIDE the damn car, like a
Big Red Button in the BACK, OUTSIDE like the Nedra rules? That's
wgat I thought that paper sez. The state is as clueless about EV's
as I am with nuclear Fissin'! I sorta set my BIG fuseholder up in a
positition in my Jetta trunk , planning a steel Cam Over setup you
could pull outside the car, right above where it sez; ":Led Sled"
which would pop the 200 amp fuze out. If forced onto the issue? Not
crazt about an obviously marked thing like that in public.CDOT
didn't have that on any of their Forces from Solectria. CT DID have
an intreaging program, in the DOT with a few EV's. Thats wHY the
"Electric" tag is taken. I asked, was willing to actually PAY
Corrupticut for ann Electric Tag.Maybe "Lectrik" or something like
that? I'm too cheap to PAY for a specuial tag, it doesn't give me
any better range? Does it?
I like your plans to Kill the car. If UI were the inspecter??OK
by me.Isn't there inertional type switch thingies in some gas rigs
that kill THEM if hit?Or what turns on the Airbags?
Of course the firepeople will probably want to hack up as many
cables they can find, in a wreck? They LOVE to do that! So try to
stay consious, after the wreck, to protect yur investment<G> They
CLIMBED all over Tony's Rabbit in Worchester during HIS fire.
Christ! They coulda pushed the car to safer ground, unharmed!
Punched out a window in his Isuzu pickup! Why? Because they COULD,
to quote Tony.
What do ya do? Tow the car over to DOT in Weathersfield?This must
be an ongoing thing? I can't wait for the emmissions folks to hit
me up for a test<g>! I hope that goes as smoothly as before with
the Rabbit?? They never LOOKED at the car, took my word for it that
it was electric. Do I have a trusting voice??As a dedicated CT
Taxpayer? No hassle, guy was very nice, we chatted close to an hour!
Changed my VIN to electric powered, as they SHOULD for yur Porsche.
VIN is how they go, if car was Born with a Diseasel or Gas engine
THAT'S what it is in CT's archives, until ya hit the right guy!
Good Luck
Bob

Subject: Zilla emergency shutdown
I have to provide a means to shut down my car in an emergency. The
state wants me to provide a way
for emergency personel to shut 'er down if I run into a tree. The
emergency people want to be sure
that the pack is positively disconnected, which means the
contactors are open. My preference is to
interrupt the power at the 12 volt level so the controller will
shut itself down. I have my eye on
one of those big red buttons you mash to kill things. I'd place it
in a very prominent location
under the hood to give them the warm and fuzzies. They can also
just turn off the key in the
ignition.
Parameters:
1 - protect the Zilla
2 - sacrifice the contactors if need be
3 - make sure the system shuts down and contactors open
I have a very standard configuration with one exception. I have an
additional contactor on the
negative side of the pack which is energized when the key switch
goes to the on position. I use
the start position to tell the Zilla to start up, and it decides
when to pull in the positive side
contactor.
1. Can I use the kill switch to open the negative side contactor?
It will zorch the contactor if
it's carrying current, but will the Zilla suffer?
2. Should I interrupt the 12 volt directly to the Zilla pin 3, Key
Input (just like turning off
the key)? What will happen if under power?
3. Is there a specific connection on the Zilla for this purpose?
Thanks
Dave Cover

Replacing an EGR valve on a Honda Insight is no biggie, right?

Ahhh yes, it was the EGR valve that had mine in the shop when the noticed
the leaky part, I almost forgot.

I think you could get one from any ford car. They are in the back by
the fuel tank. If you hit the car hard enough they shut the fuel pump
off.

Hey Peekay,
Battery powered EVs go up Pike's Peak, tallest
mountain in US (lower 48).
http://www.electrifyingtimes.com/pikes_peak_ER3.html
That is elevation gain of 4700 feet in 12.4 miles.
It can be done. And I think Lee pointed out, most
times you come down those hills, so regen and get some
energy back. Your combustion engine cars cannot do
that. Maybe EVs are better on hills.
