Basically, yes :)
Here is the same item from the same ebay seller, now at a slightly
higher price: 270156126439

I've got more than 500 miles on the set now so I left positive
feedback.  Buyer beware still of course, but it seems good so far.

Hello, all,

Now that a week has gone by and my brain has landed again, I'll try to write a 
bit about last week's race.

Early Friday morning the '62 Datsun and I, with Frankendragon on board, headed 
out from Burien toward Portland.  The trip was fairly slow and uneventful.  The 
little pickup managed 66 mph as a top speed in one stretch.  We arrived at the 
Wayland Juice Bar around 11:30 am, just as the EV clan was gathering.  

Michael Kadie was already there doing some last minute tweaking on his 
beautiful Cobra.  The battery management system is fascinating.  Hundreds of 
small red LEDs light up the back of the car like a Christmas decoration.  

I was expecting to immediately race off for food, but with the new Wayland Diet 
Plan, there was less urgency.  So instead I went and checked into the Motel to 
nail down my sleeping arrangements.  

About 4:30, Roy and I left for the track in order to be first in line when the 
gate opened, so we could start setting up the EV pit area.  We were able to 
tape off a nice sized area, which allowed us to have non-racing EVs on display. 
 (This worked so well that we did it the next night also.)  Soon the whole 
"herd" showed up and the fun began.  

Anyone on the discussion list who can possibly do so should attend one of the 
NEDRA races somewhere in the country.  They really need to see first-hand the 
performance capabilities of electric vehicles -- these are not just stodgy golf 
carts we're talking about.

Frankendragon performed much better this time out than last time.  The launches 
were hard, although the top speed was not as high as I had hoped -- only 72 mph 
at 16 seconds.  I was able to get in two runs that night.  

Our "show and tell" and brunch on Saturday morning at The Village Inn was as 
impressive as it ever has been.  The hospitality at The Village Inn is 
wonderful and much appreciated.

Saturday night I was able to make two more runs.  We were rain-delayed at the 
beginning, but that gave us a chance to set up our area and spend a little time 
on PR.  The last run before the rains returned was my best run.  I'm beginning 
to re-learn how to ride the bike.  Its hard launches require a slightly 
different style of riding.  My second run was the last of the night for me.  On 
the return leg I came around the end to the return lane and there was zero 
lighting as well as a jog in the return lane.  As a result, I didn't jog.  
Noticing the roughness of the surface and the weeds, I tried to reorient myself 
to the return lane, but discovered in front of me a piece of curbing (such as 
in a parking lot) traveling about 25 mph.   It's really NOT a good idea to try 
to jump a drag bike.  Although the jump was completed and I continued back to 
the pits, I found that the front rim was bent, the rear wheel was knocked out 
of alignment, and the fork tubes were also bent.  

Shortly thereafter the rains returned, so we loaded up and headed out for the 
post-race dinner and BS session.  

Sunday morning some of us gathered again at the Village Inn for breakfast 
before heading back to our respective destinations.

The trip home was slower than the trip down.  The little truck started missing 
occasionally, and I had to stop periodically to let it rest.  It made it home 
and I parked in the driveway, and that was it.  The next morning the truck 
refused to start, so I've spent most of this week trying to find vintage truck 
ignition parts.  No luck so far.  (Any suggestions for '62 Datun parts sources? 
 Please email me.) 

I did spend a little time realigning Frankendragon's rear wheel and there 
appears to be no damage to the rim or tire.  I have a spare set of tubes, which 
I will be changing out shortly.  But the front rim is another matter entirely.  
It's a 14" x 28 spoke rim, for which I had turned a custom billet-turned hub.  
I hope to be able to relace another rim.

Well, enough of that, I need to finish off this message and go eat my home-made 
sourdough pancakes made from Jessica's grandmother's 40-year-old (vintage) 
sourdough starter.  (My sympathies to those of you who have never been 
fortunate enough to try them.)

Using the time honored WAG method(wild ass guess)?

Seriously I needed more setback to handle the shaft adapter than the
thickness of the plate could reasonably provide. So I made it thick
enough to hold the threads i wanted and thin enough to waterjet and
afford. I fine tuned this to make my bell dpth standard and the plate
thickness standard. I felt that keeping it thicker than the tranny
casting meant it was strong enough.

*Please Don't laugh at the strange profile. I thought I was gonna need
additional mounts to frame and the flat top was gonna hold a shelf for
the battery box or controller. I decided I didn't want to subject them
to the road shocks.

Lee,
 

How many of those caps are in a Curtis?  

I just replaced the capacitors in a 10-year-old Curtis 1221.  They
weren't "bad" per se; just old. I have an ESR meter. The old caps  were
Nichicon VX series, 220uF 160vdc. Their ESRs measured 0.06 to 0.13  ohms.





Thank  you,

I'm curious, what NEDRA class does that vehicle race in? I ask  
because I can't find any class that looks like it would fit a kit car  
that is not a replica of a production vehicle.

ALERT

This is an alert to a problem that I had with a brand new "CC Power" DC/DC
converter. This is NOT to disparage the product or company, but to report
the FACTS surrounding my actual situation and my personal OPINIONS.

It appears that I had an almost immediate failure of a "CC Power" DC/DC
converter (C400) in my new conversion project. I don't know the cause of the
problem yet, but have alerted the distributor I purchased my converter from
to see how they intend to resolve the problem.

In addition, TimK, in his blog ( http://914EV.blogspot.com ) yesterday also
reported the failure of the same companies DC/DC converter in his project.

My advice is this:

If you have a "CC Power" DC/DC converter and have not yet installed it, in
my opinion, you should NOT hook it up until you are reasonably assured it
won't be fried and if it is, you can be made "whole" again.

If you are considering the purchase of a "CC Power" DC/DC converter, be sure
you have total agreement with the seller that if you incur a problem, the
matter will be quickly settled to your satisfaction. In my opinion, this
only makes good sense and something you should do with any product from any
company, not just a "CC Power" product.

Ps: There is a possibility that the converter supplied by the distributor
was not suitable for the intended use. I am requesting that the distributor
address that possibility.

In the US established notations, many things like that are backwards
vs what you'd intuitively think. If something is bigger, naturally
you'd assign a bigger number to it, sort of 3 mm is bigger than 1mm.
(or something of 3 feet is bigger than of 1 feet).

Yet, consider wire diameter - more gauge number - less diameter.
Instead of simply specifying diameter (or crossection area),
AWG system was established where wire diameter associated with
a number. larger number - smaller diameter. Now you got to remember
which number is want diameter.

Similar - for sand paper. You'd think more number - larger grain
(the number just represents size of grain), but it's opposite.

Similar for bolt/nut sizes.

If you grew in the US and and don't know any better, you're accustom to
it and it's comfortable system then. That is unless you try what whole 
rest of the world is using, but too many die hards to try seriously.

Have you heard expression "Don't ask fish what the water is like"?

Its like braking old habit, say, quitting smocking - you're far better 
off at the end, but the process is painful and discomforting for
human nature, (and, in case of industry - expensive) so instead
people come up with all sort of excuses justifying doing nothing.

Funny thing is that's the people who qualified to compare the least
(never experienced any alternatives themselves) defend it the most :-)

So you're stuck with "taller" gear even though reduction ratio is lower.
Don't apply logic here, there isn't any (or rather, backwards to 
intuitive understanding), just established and settled
conventions. It is very American thing.

Sorry, got too far OT.

John and all
Barona is only a 1/8 th mi strip but it is NHRA
approved and racers qualify for NHRA class points?(not
sure how it works but the track master was telling the
drivers that they could qualify to go to the Winter
Nationals at Pamona)  anyway Michael got in five runs
the best being a 7.91.  he needs lots of practice and
the car needs much tweaking but he was blowing away
the blown hemis with 12 in slicks to the point that
his last two runs no one wants to run with him and get
embarrassed by an electric.  I may have to become a
taunter to get him any heads up races.  He hasn't even
turned it up yet still running at 1400 motor amps  and
less than full pack voltage.  so there is still lots
to go.  the speed channel was there and spent lots of
their time with Michael so look for something when
they do their electric veh show with WZ, Killacycle,
and orange juice.  this looks like the year of the
electrics so any of you who are inclined toward racing
should take advantage of it.

I notice many people discussing the number & location of batteries they
can use in their donar cars.  A trick that has served me well was to
purchase a plastic scale-model of my donor.  I lucked out in that it was
available in 1/8 scale.  I "semi-assembled" it, leaving body, etc.
free, for easy removal.  I cut models to scale of proposed motor,
controller, batteries, etc.  I cut out the body sections that will be
modified in the real thing, and then played around with different
configurations.  At 1/8 scale a 12v flooded is about an inch long, so
it is quite practical to do this.  If you can only find the more typical
1/25 scale kit of your donor it will be a bit more challenging...

It has been quite helpful to me, I suggest people in the idea/design
phase search the net for available models in their car of interest.
