Supposedly Toyota kept it simple between the 4wd and
2wd. My truck is 86 4wd which EA made the adapter.

Mike Willmon queried: "So Rod, when he's knocking on 10's will the Maniac
Mazda come out of retirement?
The answer to this question is a definite YES! There is a very old saying
that goes something like this:, "Competition drives the sport". After eight
long years it is finally time to bring out the "Maniac Mazda" from the moth
balls. Even though I have not been racing it I have learned a lot from
reading John's posts, as well as Bill's and Dennis's. I also learned a bit
from "Gone Postal". I am going to incorporate many of these things in the
car. The motors will be coming out soon and shipped to Jim, with his
permission of course. I realize I will have to get in line. I am quite happy
with the way I choose to siamese them so that will most likely not be
changed. I am still a firm believer in the transmission so that is staying.
Since you can only get so much torque out of 2000 amps you need another way
to multiply torque, especially in heavier vehicles, and transmission have
been serving that function for years. When the resurrection starts I will
keep you all informed.

Yes thanks Rod for the excellent coverage! And congrats to Tim and John
and Jim. This is great, you'll have to let us know when
the Street is going to run the story.
Is WZ running the new 3.70 gears yet? Or are they saving it for the
lithiums next month?
If the 4.11 is still in I figure they were turning 6299 rpm at 110.14 mph
on the motor.
With the 3.70, even at only 6000 rpm they would run about 116.54 mph. If
the hole shot only suffers a couple tenths, the over
110mph part at the end will more than make up for it. Although with the
lowered weight of the lithium pack the hole shot should
improve, even with the taller gear.
So Rod, when he's knocking on 10's will the Maniac Mazda come out of
retirement?
I can't wait until next month.
Mike,
Anchorage, Ak.

The two large field coils makes the back iron requirement large on a dc
motor.
In an AC induction motor the 24 to 36 coils and rotating magnetic field
make the back iron requirement way smaller. The trade off is that
laminations are required to prevent eddy currents.
The path of the magnetic field in the dc motor is 180 degrees and al the
magnetic "current" in this path. Makeing thick iron.
By contrast, the path in the AC motor is only 10 degrees and the
"current" is a fraction and not constant.
So often you will see an aluminum case where the wound laminations are
pressed in.

Great reporting Roderick!
Congratulations to John, Tim, Jim and the Zombie!!
Jim your motor work speaks for itself. Great going!! The pressure is
off and you deserve a drink, as if there was any doubt. And all the
tweaking John has done on the car is paying off. The Zilla keeps
humming away taking all the battery amps you can throw at it and it
sounds like it isn't even turned up all the way! Kudos to Otmar as well.
Cheers to the White Zombie Team!!

Subject: News Flash from PIR & New World Record
I just received a call from "Plasma Boy" Wayland at Portland
International Raceway where he just set a new world record on his
second run of the evening. He turned a 12.140 at 107.06 mph. This
is the first time that the "White Zombie has eclipsed 107 mph. The
first run was also impressive as the car had never turned over 100
mph on a first run with cold batteries. It turned a 12.433 at
101.99 mph. On his second run he blew the doors off the Vette in
the other lane.
This historic event is being filmed and written up by a reporter
from The Wall Street Journal. They had done an in-depth interview
with me two or three weeks ago. They are really doing their
homework. The story will be on the development of EV Racing in
America and on NEDRA. By the type of questions they asked me I feel
confident that they intend to get it right.
John predicts he will break into the elevens on his third run, The
new advaced timing seems to be doing the trick and all the hard
work Jim from Hi Torque has put in. Sadly Jim is not there to view
the siamese 8s in action. John told me to give him a bad time but
I think I'll let him slide. I am sure he feels enough guilt
already :-)

When I was younger and at the beginning of the learning curve I thought
a starter motor would be good for running a compressor on my 4x4.
After I machined room for bearings and fitted a pully for a belt, I
found that it always got really really hot, in short order.
I believe not only was it not optimized for effiency, that something in
the "design for intermittent operation" also makes it unsuitable for
continous operation.
I then switched to a honda starter motor, it looked more conventional
and ran fine. I never got around to trying one of those motors from the
gear reduction starters.

Where I work, they have a lot of golf carts used from everything to move
parts between buildings to delivering lunch to employees from the campus
cafe.
As I was going to lunch two fully charged golf carts, (they charge
inside my building) came zipping out and around the corner, it was quiet
close as i guess golf carts don't have the greatest brakes?. He had to
steer along side and up against the dumpster to avoid the collision
leaving the golf cart behind him almost no place to go.
We all went from wide open eyes to laughter when I shouted out "my golf
cart is bigger than yours" The people who drive these golf carts all
day, are asking questions about how they can do the same thing. Kind
of a gas roots growing within the company.
(I am sure they were quiet worried, as a memo had just come out about
security will begin handing out tickets for people drive the golf carts
to fast)

Hey all
Man, news sure travels fast as I was watching
Letterman last night and he had this top ten list.
Number 10
Your ball sack looks like sun dried raisins, and you
don't know why, because the guy in the next lane
stalled his engine doing the burnout and hasn't EVen
restarted it!
Number 9
You realize you'll be having raisins for dinner as you
can't read the guys license plate at the 1/8th mile!
Number 8
The car your racing has had cameras placed on the
sides to capture the burnouts, or so you thought, but
now realize they were placed there to capture your
facial expressions when you can't read his license at
the 1/8th mile!
Number 7
The idiots in the pit next to you feel they need 60
batteries to start their engine, and still have to
recharge them after EVery race!
Number 6
You find yourself singing "Bye bye Miss American pie"!
Number 5
You hear officials telling the guy in the pit next to
you that he may need to hook up a Vroom box before he
can race again!
Number 4
You hear MGM is talking about making a new terminator
movie!
Number 3
The Wall Street Journal is there taking pictures of a
little white Datsun 1200!
Number 2
You're about to race against a little white Datsun
1200!
And the number 1 reason you know your about to be beat
by an Electric car is he's running a Hi-Torque motor
8^o (sorry couldn't resist) 8^)
Anyway straight from Lettermans mouth, hope you all
enjoyed!

After sleeping in an hour late this morning myself, I awoke to the flurry
of messages about 110 mph quarter miles in a street legal EV.
Congratulations to the White Zombie crew for all of their achievements.
Maybe John won't need adjustable brush timing after all.

I wanted an insight and went to the honda dealer 5 or 6 times. They only
once had 1 automatic once.
All the sales guys kept saying over and over, "You don't want one of
those, you want a hybrid civic...
After about 40 min of these guys not listening to me I left in
frustration and build my time share hybrid. (I drive my old ice once a
month or once a week)

Hey Mike
Well I just had to get John up and running so he could
get his last lick in before you try and clean his
clock, LMAO! I do think I better try and get your
housing back from the paint shop and drill a few new
holes in it (can anyone say Swiss Cheese 2) 8^o
Better to do it now and at least have the option of 15
degrees advancement available.
It's taken me two long years to get this data and it'd
be stupid not to include it into your motors.
Anyway I'm betting that John's gonna love the heads up
comp you'll be adding to the mix here soon 8^)

There is a franchise called techshop. This weekend they have an
openhouse in menlo park
http://www.techshop.ws/
For about $100/month or $1100/year you can get a pass to use their machines.
Man I wish they had one close to me! You can get day passes and I am
sure they make you take a $30 class before they'll let you loose on the CNC.
( iwas thinking I can come in there with 25 years experiance in
machineing and talk my way out of those)
Let me offer one more thing.
In my adaptor, i have a .625 or .750 thick aluminum plate that the
motor mounts to and the tranny mounts to. It has a weird shape because
I have a 12" diameter bell ( http://www.jfs-tech.com/cvevs/dsc00057.jpg
) attaches to the motor, sets the backset, and allows to pull the motor
out with the clutch on it, thru the hole.
http://www.jfs-tech.com/cvevs/Z31_non-turbo-pattern.jpg
http://www.jfs-tech.com/cvevs/dsc00037.jpg
The point was that it took about $40 to have the shape of that plate cut
out with a waterjet by a local counter top place.
I am sure most major citys have at lease 1 water jet in town.
I have seen it cut stone,plastic,wood,stainless steel,low
carbon,titanium, and copper. 1/8" to 3" thick (accuracy is poorer as
thickness increases)
The accuracy is not great(better than plasma, worse than laser), Use it
like a casting. The edges look like they have been sandblasted. The
entry and exit point end up with a little dimple as the stream drifts.
This machine accepted a dxf file, allowed the guy to add some path info
and they took a few moments to cut.

Watts is Watts
I think a low voltage system inheritantly has this problem. My system is
300V. 90V at 450A would be only be 135 amps from my pack.
f=m*a
2500lb
.5 G accleration (.5G is avarage, .7 is sporty, 1G+ is race)
assume a 24" OD wheel for 1 foot torque arm and 840 revolutions per mile
if you had 2500lb of force at the ground you would have a 1G launch
so lets say you have 1200 lbs of force to give, and you want to maintain
this 1/2 G acceleration until you reach speed
on a 24" wheel that is 1 foot radius so 1200lb.ft of torque.
Assume 4:1 rear end and 7:1 gear that is 42 lb ft at the motor looking
at the charts
http://www.evparts.com/shopping/products/mt2116/torque_curve1.gif
that is 275 motor amps. and at 3800 rpm you will have only that amount
of torque avial so equalibrium is reached. 135 wheel rpm or -cough-
~10mph.. time to shift.
I assume from this calculatioj that you to have a 2nd gear for a total
of 12 :1 and you are useing that?
1200/12= 100lbft = >500Amps! But your controller limits to 400, you get
<75lbft so less than steller acceleration.
This ignores in effiencies and I am sure that you are actually
accelerating faster in the beginning then tapering off.
In my EV I have a 9" and I start in 2nd gear togather this is about 12:1
ratio but my car weights 4050
1/2 g would be 2025lbft of torque or 168lbft to the motor at 170V max
setting. This is 750 Motor amps 750*170/300 = 425A.
This is what I see on a brisk acceleration.
You will notice that you didn't get the last calculation. You can't take
advantage of a higher pack as well as I can to keep the battery amps down.
I think you will find improvement when you correct alignment, but I
don't think it will be drastic.
I can't find good specs for the 1221R, The C version is 12V 400A. (I
heard the 1221R is 375A) Maybe it can handle 120V and bumping the system
voltage up a little will help.

wow
I wanna come watch
congratulations to all
when and where is the Wayland invitational? can I
bring my BugE for a non NEDRA run or is NEDRA going to
create a class outside of the NHRA for trikes since
there are a lot of electric trikes??

I don't think I'll guess. I've heard that the TS cells sag quite a bit
(someone correct me if that's wrong), so under load they may actually have
*less* voltage than your 42v of lead batteries. On the flat, the lower mass
will reduce rolling resistance a bit, but I doubt that it will have a
dramatic effect on top speed. No doubt you will get there faster though
(better acceleration), and you should be able to climb hills faster.
I just hope you're not getting a batch of substandard TS cells, as some on
the EVDL did a few years ago.
In any case, let us know how things work out.

If the 2wd and 4wd have the same pattern I guess it will be as simple
as swapping the bellhousing with one that EA has a pattern for.
So do you all recommend buying an adapter if possible rather than
trying to make my own?

I was just in a local alternator and battery shop to see what was
available. He does carry Deka's, so if I do go with the gels I can get
them from him.
anyways he called his supplier in Anchorage to get a price quote on
the AGM and Gel Deka's and told the guy what I was going to use them
for. His supplier recommended Gel for an EV <shrug> he also gave him
the name of a guy I should contact who is an EV specialist in
Anchorage, named Mike Willmon :D
When buying so many batteries does it make sense to try and get them
from the supplier at wholesale cost.. is it even possible?

"My question is whether a similar strategy can be employed to keep
NiMH packs balanced while charging?"
I am assuming that you can do the same thing with NiMH batteries. But
I have heard some place that when you have several seperate chargers
instead of a fancy main one, that you end up needing electronics to
coordinate the different chargers together or something. I'm not sure.
Hopefully someone can clear this out.

I'm not sure what you mean. The idea here is that each charger
monitors its own battery (in the case of AGMs) or small string of
batteries (in the NiMH case) and turns itself off when that group is
done. In this way each battery is kept in balance, as it receives a
full charge regardless of how fast or slow its neighbors charge. Its
key that the chargers are fully isolated so they can float relative
to each other and charge the batteries while still in a string.
See the link here (about half way down) for an example of an AGM
implementation:
http://www.econogics.com/Soneil/sonindex.htm
In this case the advantage is that you can run 10-12 $70 chargers at
a cost of $700-$840 instead of a $2-3k fancy charger & balancer
solution.
My question is whether a similar strategy can be employed to keep
NiMH packs balanced while charging?

I read a while back that one of the Chinese EV makers is fitting an audio
system which goes "Clip-clop, Clip-clop..." imitating a horse to prevent
gormless pedestrians from leaping out in front of the car as it drives
silently along.
I'm afraid (as you may have gathered) I lean towards the argument that
looking before leaping is the best plan. After all, if you are a cyclist
and someone steps out in front of you and causes a collision, you stand as
good a chance of being injured as they do - and whose insurance will you
claim off?
It is about time we had jaywalking-type legislation here in the UK (hey! -
we seem to have it for everything else these days - Thanks, Tony!).
It is also no surprise to me that so many fatal accidents occur on
pedestrian crossings - like a bit of paint on the road is going to
automatically suspend the laws of physics. LOOK and KEEP ON LOOKING as you
cross. Isn't that what we teach the kids?. Rocket science it isn't.
As for Harley's making the noise of 3 40 ton trucks "because it's safer"...
OK, you can't deny that you (and everyone else witching a 500m radius) will
hear them coming, but I'm inclined to think it's actually more to do with
the size of a certain piece of the riders anatomy, myself. The same applies
to any other idiot who inflicts his cacophony on me - however many wheels
his chosen form of ICE'ed transport possesses.

Tehben,
No doubt his supplier is John Gonzolas at Auto Electric & Battery. He has the
Alaska EVA set up with an account and will give you
the good guy pricing if you mention you're a member of the AlaskaEVA group.
Baically what it comes down to is you'll pay their
wholesale price plus a very small markup and they pick up the shipping (which
can be $30-$40 a battery) with their normal stock
orders that come in every couple weeks. If you want I can give you John's
contact info and you can talk to him directly. He can
either hold them for you if you want to pick them up or help you make
arrangements to truck them down. I'd be hapy to help in
that regard as well, except my truck would barely make it to Girdwood :-( I
was originally going with the Deka Gels but talked
myself into the better performance for the first run. I may go back to him for
gells when I'm done with this set of flooded Crown
batteries.
Mike

Is there any import left to it?
Engine, tranny, rear end have all been replaced.
This thing is now 100% grade A American mutt.
Better hurry up and install a roll cage or they might shut you down after
that first run with the A123's. :)

There's not much design involved with the adaptor plate.
Just a couple things to keep track of.
One is to make sure the bellhousing holes are indexed to the center of the
crank and the other is to calculate the thickness you need to position the
motor shaft and coupling in relation to the transmisison input shaft.
It can be broken down into two separate problems.
6061 aluminum plate is nice to work with and be cut on a wood cutting band saw.
If you do it by the seat of your pants, you'll have to come up with a way to
index the plate to the center of the crank as you mark the bellhousing holes.
If you are dealing with a transaxle and the transmission input shaft is not
supported by a pilot bearing, you can index the plate to the transmission input
shaft and mark the bellhousing holes directly on the plate using transfer
punches. You just have to find a way to end up with an accurate location of the
center of the crank or tranmission input shaft in relation to the bellhousing
holes.
Have to drill the right diameter holes through the plate with a drill press.
A good way to split the adaptor plate problem into two separate problems is to
incorporate a spacer ring.
So you have to open up that accurately located center punch mark. little hole
or big hole that locates the center of the crank / trans shaft to accept a
spacer ring.
Problem is how to accurately open up that center hole especially with the tools
or limited machinery you might have.
You wil probably have to take it to a machine shop. If you have an end mill,
it's possible to accurately do it. Not pretty or easy, but possible.
The spacer ring has to be turned on a large metal lathe.
The spacer ring has to be indexed to the plate and this is done by machining a
flange on the spacer plate that fits the hole in the adapter plate. Chose the
diameter of the the center hole in the adaptor plate with a little thought and
you will only be screwing up the spacer ring if you goof up.
Plus if you ever want to change something later on, like a motor or go from
clutch to clutchless and need to adjust the distance between the motor and
transmission or mounting holes, you are only dealing with a spacer ring.
Then the spacer ring has to be accurately indexed to the center of the electric
motor shaft.
Once again you have to mark the holes after you fit the spacer ring to the
little flange on the motor which is concentric with the motor shaft.
You should end up with an adaptor plate with bellhousing holes that are
accurately located in relation to the center of the original ICE crank, the
center of the crank should be marked on the plate and accurately opened up to
the correct size hole to recieve a spacer ring. The spacer ring flange that
mates with the hole in the adaptor plate must be exactly concentric with the
center of the electric motor shaft.
So little motor flange fits into spacer ring, bolt holes marked, flange on
spacer ring concentric with hole that accepts little motor flange, everything
concentric.
Flange on spacer ring fits into hole in adaptor plate. Spacer ring gets bolted
to adaptor plate.
Adaptor plate hole is concentric with original ICE crank.
So motor shaft should be lined up with center of transmisison input shaft.
Of course, you still have to determine the thickness of the spacer ring so you
end up with the clutch disc hub in the correct operating position on the
transmission input shaft.
Whether it is clutchless or not.
The center hole and it's accurate position in relation to the bellhousing bolt
holes is critical on the adaptor plate.
There is less opportunity for error when machining the spacer ring concentric
holes and flanges on the lathe.
There are much better ways of doing this of course, like actually measuring
stuff or using modern machining methods.
It's more difficult to make up a taper lock hub or modify a taper lock hub at
home.
If ElectroAutomotive has your plate and hub, it is worth it to buy it from
them. There will be plenty of other work to do on the car..
I hope this helps a little
Dana
