Subject: Who handles NEDRA tech questions for new builders????



Hi Everyone,

I'm getting into the process of elimination on various project ideas of
late. Who can I direct specific questions to regarding what qualifies a
vehicle to be classed one way or another?

My goal is to build some sort of two-wheeled vehicle that can be safely
riden and raced without getting the black flag during tech inspection at the
first event I show up at.


I also have some questions about specific building techniques and component
placement that I would like some reassurance on before I commit hard earned
time, materials and hours of labor.


Just for those who may be wondering, I'm moving up the food chain from
ebikes. As fun and simple as they are to build and ride, they just won't
smoke the back tire. ;-))
It's all Bob Rice's fault!!!!! He had home movies of Woodburn and allowed me
to make a copy of it while he was here visiting in Phoenix.


Thanks and regards,
Rick Pryor

I have no idea how well it would work for driveline components, but
Harley Davidson uses it extensively on their motorcycle engines.  

I was once at a event where one of the companies that founded the cryo
process was exhibiting.  They were handing out off the shelf cheap
disposible razors that they had treated.  For me, cheap razors last
maybe a week before reaching the painfully dull stage.  The freebie
razor was lost on a business trip eight months worth of use later, and
it was still as sharp as when I started using it.

Standard technique on a racing dog gearbox is to undercut each dog by
about a degree so that torque forces them fully engaged.  This also
permits an extremely rapid shift.  The technique involves pre-tensioning
the shifter with your foot or hand and then winging the kill switch to
cause a very brief interruption of torque.  The same technique should work
with electric drive.

Can you program the controller for zero acceleration ramp?  That would
seem vital for blanking the pot fast enough.

I can envision a very fast setup.  A spring in the linkage strong enough
to effect the shift stores energy.  As the shifter handle is pulled
against the spring, it hits a microswitch at the end of the travel which
interrupts power.  The shift is then spring driven.  A switch on the other
end (tranny side) of the spring restores power when the shift is finished.
This would not only be lightning fast, it would also guarantee the dogs
are fully engaged before power is re-applied.

That's would be a nice choice. I'm on a Caddy list where a guy is running
11's with a souped up 500 and the stock tranny. This in a car that's
about
the same weight as GP.

Yes, spectacularly.  Several cycles between LN2 and about 300 degs works
even better.

how about an electric linear actuator for throw with
the same micro switch function as described ? this
would mean shift function could be made from a
tiptronic paddle or a button on the wheel near your
thumb.

They're talking about solar cells, not "batteries". I suspect what they
meant was that solar-powered cars have run in multi-day races that
covered over 3000 km total. For instance, the solar car race from Darwin
to Adelaide Australia (1950 miles, 3120 km).

--- Begin Message --- With all the talk about brakes, I thought I would get in here and ask a question about the brakes on my truck that I haven't been able to figure out.

First the setup:

Metricmind self contained vacuum pump, works like a champ
4"diameter by about 6" long PVC vacuum reservoir
Standard Chevy S-10 (-91) vacuum booster and master cylinder
Rear drum, front disk brakes, stock for the 14" original wheels
All pads replaced within the last 20k miles
Rear wheel anti lock system, non functional at this time

Now the problem:

If I hit the brake pedal hard and very suddenly, it seems like I'm getting no perceptible braking for a little while and the pedal does not seem to sink down the way I would expect. If I depress the pedal slowly, then all works as I would expect. If I push the pedal down slowly but firmly and the truck is traveling along at a good speed, like 20mph, I can take the pedal all the way to the mechanical stop without locking the brakes. If I am stopped with the vacuum pump stopped (system at max vacuum), I can push the brake pedal all the way to the mechanical stop.

I suspect air in the system somewhere. I had the brake pads and rotors professionally serviced the last time. I am wondering if they were successful in bleeding the brakes properly.

Anyone have thoughts on items to check, or should I just expect slow braking for an about 3k lb vehicle?

Hello,

I'm finally going to get my Jet Electrica running this winter.  I need
new batteries and was wondering what are the pros and cons of using
6-volt vs. 8-volt batteries?  My car will hold 20 T-105 batteries.  So
am I better off using 20 6-volt batteries for a total pack voltage of
120, or 18 8-volt batteries for a total pack voltage of 144?  Will both
battery packs last the same number of cycles?

Thanks,

An ongoing question.  I am now in the middle a science experiment to
answer these questions:
All miles were on the same commute 43 miles to work, recharge, 43 mile
home recharge etc. (with a little variation as you can expect commuting)

Which is better, US Battery 8VGC's or US Battery 8VGC-HC?

Answer:  The 8VGC gave me 12,300 miles, the 8VGC-HC gave me 14,100
miles.  Pound for pound the same milage, but the -HC leaked something
awful and I had massive acid build up in the battery boxes (and
continual odor).  Probabally something to do with the higher level of
acid to cover the expanded plates, without increasing the case height.
I would recommend the 8VGC over the 8VGC-HC's.

Which is better, US Battery 8VGC's or Trojan T-825?

Now running the T-825's and have 6,400 miles on them.  No issues so far,
but then the US8VGC were good at 6000 miles too.
An answer to this question should be available next March (the time
where I should surpass the 8VGC milage)

When the T-825's can no longer make my commute, I will be changing the
car over to 108 V system using T125.  So around spring time, 2006, I
will have an answer to the your question backed up with real world data.

General advice on the list is that 6 volters give longer life than 8V.

Subject: 6-Volt vs. 8-volt Batteries


Hello,

I'm finally going to get my Jet Electrica running this winter.  I need
new batteries and was wondering what are the pros and cons of using
6-volt vs. 8-volt batteries?  My car will hold 20 T-105 batteries.  So
am I better off using 20 6-volt batteries for a total pack voltage of
120, or 18 8-volt batteries for a total pack voltage of 144?  Will both
battery packs last the same number of cycles?

Thanks,

I had the same thing happen to me, after I had the brakes, brake lines, 
vacuum booster replace replace in a major replacement of all parts 
overhauling.

Having one person filling the brake reservoir and another one pumping until 
brake fluid comes out at the brakes may not be effected 100 percent of the 
time.

I had the same indications you have.  I went to a parts store and bought a 
brake servicing tool, that pulls the fluid out from the reservoir to the 
brake bleeding values.

There was a lot of air in this fluid, so I replace it with a new brake fluid 
that did not absorbed air. I ran twice amount of brake fluid through the 
system to flush all the lines out.

The 7K Lb EV stops like normal.

Hi Bob,

I get 2-3.  The pump inside the battery box is not quite as loud but it
is noticable.

Subject: actuations of brake/reservoir size


Okay EVers; how many brake actuations are you getting
per pull on the vac. pump?
I'm getting ONE!  It's a Randy Holmquist pump with a
KTA reservoir (about 18" long x 3" dia).  It just
seems like I got more with the setup Mike Brown had on
the Rabbit.  I've replaced the vac. booster, and maybe
I'll have more actuations after I bleed the line, but
right now it looks like still one brake actuation per
pump pull.  (This model is non-adjustable).
Thanks,

Back on the road today with a used T-Rex 600 replacing the Raptor 600
that I smoked.  

Every thing is working great, except my Emeter is no longer reading
current (voltage is fine, but current reads 0).  Curiously, my back up
analog amp meter continues to indicate current drawn.  Of course, since
the current is not being read, all the nifty emeter KW-hour, percent
used and fuel gauge features do not work.  Is there something I'm
missing or is this a standard indicator of a emeter problem?

Glad to be back on the road!

Always put a diode across (in parallel, cathode to +) any inductive device
(pump in this case). This keeps the back emf spike 100's of volts from
frying your contacts and not to mention and uP controls that may get
glitched when the pulse goes through the wiring.  I also put an inrush surge
protector CL-60 in series to cut the noise in half. It used to go BURreeee,
now it goes urreee. Mark

--- Begin Message --- Thanks for posting the pic Dave. I was wrong. I guess my memory isn't that good. Yes the diff is in front of the trans just below the engine but I believe it was to the rear as I vaguely remember a cutout in the rear of the pan for an axle crossover. I will have to take a trip to our local wrecking yard, time permitting. It is still a mute point as we don't have the real estate. Our firewall is 10 inches from the centerline of the front axles. I will reiterate to the folks on this list. This is a tiny vehicle crammed with batteries. If you could put this set up in a Rabbit then you could put it in GP but there isn't room.

The next time you folks see one of these Cadillac Eldorados or Olds Tornados notice the length of the hood. It was not a styling decision! The transmission is in front of the differential and the motor is in front of the transmission. Now go to www.suckamps.com and notice the distance from the centerline of the front axles to the front of the vehicle. You will not need a measuring device to tell you that it is not feasible in your wildest imagination. It would be far easier to stuff an Allison V12 in a Nash Metropolitan :-)

PS: For those not familiar with the famous Allison V12 engine there is a nice picture of this 1710 cubic inch monster at: http://images.google.com/imgres?imgurl=http://www.geocities.com/whoppanz/Dsc01008.jpg&imgrefurl=http://www.geocities.com/whoppanz/allison&h=680&w=1024&sz=75&tbnid=pFu1UL5r-MEJ:&tbnh=99&tbnw=149&start=1&prev=/images%3Fq%3Dallison%2BV12%26hl%3Den%26lr%3D%26sa%3

That's would be a nice choice. I'm on a Caddy list where a guy is running

about
the same weight as GP.

Yea if we can find one....this would be really nice.

OK Rich, I'll sniff around here in CT , if one lays, unloved in a local
