Title: Re: electric motorcycle performance
given current readily available technology, what's the approximate
performance potential (top speed, power, weight) of a motorcycle set
up specifically for roadracing?

Do you want to road race competitively or just play?

Let's hope George just wants to play. I cannot see any technology any time soon that would make an electric motorcycle competitive with an ICE on a road course.

I get a charge out of watching the drag racers blow off the Vipers and the Vettes.  Now imagine riding like that for not just 1/4 of a mile but for 10 laps around a 2 mile road course with hills, off camber and blind turns the whole time with three or four other guys literally rubbing elbows. I still have tire marks on my leathers.

I just don't see how an electric could hang.

Man, I wish I had the money to go racing again!

I made the mistake of pointing out that he could be more competitive if he considered moving over to an EV (well ok thats not EXACTLY the way I phrased it, LOL) and he got so emotional that he offered to chase me down in the pits and kick my butt. Frankly I wasn't so worried about him but his wife was awefully big and equally pissed about seeing the car they built instead of a down payment on a house getting tromped. In total silence. Glad I wasn't him last night when she got him home.

Subject: White Zombie - '74 Nova V8 Drag Car Comparison


Hello to All,

I had an interesting conversation today with one of those folks that Tom Shay says isn't interested in electric drag racing. He was just one of my many customers on my forklift service route, an average guy working in a warehouse. In the past we've had a few short conversations about my electric car addiction, and he's always been 'interested' but not over enthusiastic...until today, that is. I had told him the results of our weekend's racing efforts, and reported that the car had run a mid 12....his eyes got big. He then asked, "What was your 1/8th mile like?" I told him our best 1/8 mile portion was a 7.917 @ 85 some-odd mph, and also told him one run had us approaching 87 mph (86.57) in the 1/8 mile....his eyes got a bit larger. That's when he surprised me when he told me that he too, was a drag racer. That's also when he gave me some very interesting info on his '74 Chevy Nova drag car. He went on to tell me that his 'thing' was 1/8 mile drags, not the usual full 1/4 mile as is mine, and he said he'd tuned his machine to haul ass especially in the 1/8 mile....his best time ever, was a 7.92.

Here's a short list of his muscle car's specs:

383 cid 'stroker' Chevy V8
Edelbrock Torquer intake
Edelbrock 650 cfm 4 barrel carb
Headers, big cam, and exhaust
2500 rpm stall converter
B&M 3 stage shift kit
Mickey Thompson wrinkle wall drag slicks

Food for thought.....White Zombie does almost exactly the same time with its 7.917 vs the Nova's 7.920, but does so running with street legal drag radials against the Nova fitted with the real deal, full race wrinkle wall drag slicks. Contrary to what Tom says, "... electric cars are slugs compared to ICE drag racers."....this guy who had built up a fast Nova, was absolutely blown away with what my electric car had done. He plans on bringing a group of his friends down to PIR next Friday night to watch us run against the gasser boys.

From Rod Hower:

John and Jim Husted have engineered
their own electric drive system to crank out 12.65 1/4
mile times.  That is impressive and very unique, and
the fans at the drag track recognize this vehicle....You may call 12.65
in the 1/4 boring, but the engineering and time to
create such a unique vehicle is much more impressive
than a 9 second alcohol dragster that can be created
with off the shelf parts.

Thanks Rod, I appreciate this. My friend Gene, who I met in the Fall of '03 at the track and who has the low 11 second Nova I've written about from time to time, feels the same way as you do. He gets it. We saw him a few weekends ago when we raced the Silver Bullet Z Car, and as usuual, it was great getting to talk with him again. Gene doesn't know about our recent mid 12 second run or our sub 8 second 1/8 mile times, but I'll bet that once he finds out, he'll be running around telling everyone about it. Here's guy with a far quicker car than mine, yet because it's the unexpected.... 'an electric car'... that performs way outside the perceived norm, it's super cool.

Change of subject.....I just got off the phone with Tim Brehm, and he had me freeze the launch segment of the 104 mph run I've got posted at:

http://plasmaboyracing.com

Folowing the burnout and just before the car takes off, if you pause the movie, then step the launch s-l-o-w-l-y frame by frame, you can see two very telling things....one, is the way the drag radials wrinkle pretty severely at the point of first bite. These aren't wrinkle wall tires, so I was a bit surprised to see them do this... and two, the way the rear axle winds up on the leaf springs to where there's too much fore and aft movement of the entire rear axle to my liking. I'd already planned on lengthening the traction bars to make their ends match up farther ahead right at the leaf spring pivot instead of their present contact point that's about 3 inches behind the pivot (that allow too much spring wind up). Now, after watching the crazy axle travel, I 'have' to make this mod! Additionally, Tim and I both experienced the front spings dropping away from their normal tucked-in postion with the front strut cups due to the way the front end pops up so far....we'll be fixing this problem, too. The rear end traction bar mods and front end spring control mods will go a long ways towards helping the car get out of the hole even better, and might be good for another 1/10 - 2/10 of second off that mid 12 ET, perhaps putting the car in the 12.3 second range? With better traction, we can turn up the Zilla a bit more in the series mode and maybe shave off another 2/10 -3/10 getting the car awfully close to the high 11s!

Interesting stat from Sunday's racing....With the exception of the very first run Tim had ever made down a 1/4 mile track, White Zombie was 5 for 6 at going 100 mph and more in the 1/4 mile. It's also fun to note that Tim just 'had' to make a statement with his perfect 100.00 mph that put him into the 100 mph club! In chronological order of the day:

96.47, 100.00, 102.43, 103.53, 103.92, 104.14

It's interesting to watch the speed go up as the batteries both warm up and get better broken in. After struggling to crack 100 mph in the quarter mile last year, 100+ speeds are now the norm for the car, so I guess we've made some progress :-)

Stay tuned for this coming Wednesday's 1/8 mile runs, and for the following Friday's drag racing results (weather permitting)...

See Ya.....John 'Plasma Boy' Wayland

I’ve been thinking about a motorcycle motor for some time.  My brother-in-law 
was, just tonight, asking what it would take to build him one.  Not sure I’d 
call it a dream motor but I feel an MNE series Prestolite or Advance’s version 
of it would make a good donor motor.  This motor I believe is a 9 inch diameter 
motor but is only ½ + the length of what you all know as an ADC 9”.  The 
drawback to this motor is it has only a single brush set up, instead of the 
dual brush the larger ones have.  This single brush is a little larger than the 
A89-012 brush the dual style uses, but not by much.  If one wanted to beef the 
comm. up you could wind the armature with a longer comm. and install the dual 
brush set up to this motor.  A larger C.E. plate and shaft would need to be 
fitted to complete the upgrade.  The dual comm. would increase the brush shunt 
capacity and commutation two fold while maintaining a stout but short 10 to 12 
inch length.

 

The motor was originally rated as a 36-volt drive motor with a one-hour duty 
cycle.  So if you were to say run it the 3 to 4 times the original rating that 
seems to be a norm here, I believe these motors would sing.  Now let’s break 
the field coils apart so that they can be run both in series or series parallel 
for a possible electric shift like John Wayland, but with only one motor.  Now 
you set it up with a variable timed brush ring so that you can time it to 
optimize the motors to the batteries, load, RPM’s of what you want.  If the 
type of track you are planning for has a lot of turns then the jump you get on 
low end might just make up for in loses on the top.  Someone posted a need for 
8000 Rpm’s, but if out of the corners you were faster than them just as Wayland 
is then maybe 6700 might keep pace, or as in the story of the turtle and the 
hare might win.

 

Father Time is running a pair of these stock ADC’s at the tongue-in-cheek 
Lazy-Boy race coming up soon.  I’ll be curious as to how the motors perform and 
will be picking his brain as to their output.  These motors have a good amount 
of copper mass with a nice amount of turns.  If you had the room for a pair of 
these and batteries to push them I think you would come close to where I think, 
you are wishing for.  For an average cycle builder these would be ideal.  I 
think they are around 80 to 90 lbs., not to heavy but real stout.

 

Wish I could add more details but I haven’t built one yet, hehehe.  As to the 
other areas of your post I’d do what these guy say : )

The Kokam Li-Po for your pack or try to get a hold of Compact Power's 
cells (out of colorado). Compact Power also has excellent BMS.

A Zilla controller will give you high power control lots of race 
parameters to tune and series parallel switching stock, not to mention a 
full data set to analyze.

As for motor, I think that a dual ETEK or Lemco setup would give the 
best power to weight ratio. Trying to go 100mph on one ETEK is 
definitely pushing it. Two is much better and a drag bike named ReVolt 
with two ETEKs and a Zilla controller holds a couple of world records 
using that setup at 144V (13.634 sec 1/4 mile at 93.81mph) and at 192V 
(12.958 sec 1/4 mile at 98.06mph). The ETEK and Lemco motors provide an 
outstanding power to weight ratio.

If you want to push around 100mph of course aero is critical as well.

Hope this helps!

Fill up the container and run the pump motor until the container
drains and see if the pump gets hot or burns up/fails.  I don't think
that particular pump motor was designed to be ran continuously?  Maybe
it can though?  It might work and might not, try it and see.

It may take awhile, but you will eventually learn to just do what Otmar says to do. I have never heard Otmar give a bad piece of advice about EVs.

On other subjects, he may not be quite so infallible. ;^)

Has anyone mounted a 9" ADC in a Rabbit? Electro Automotive says they don't offer a motor mount solution for the Big motor. 8" yes. 9" no. Any solution? If not I'm making my own.


I put a Prestolite in a Rabbit and didn't bother with a motor mount. I replaced the other 3 mounts with urethane mounts. The controller mount was about 1/2 inch clear of the bell housing and they never hit. Power was limited to 20 6v golf cart batteries and a rare DCP450 (about 50hp.) If you are going for alot more power (I'd guess over 100 ft/lbs of motor torque) this may not be a good idea.

P.S. - some manuals seem to indicate that early gas powered Rabbits didn't have a motor mount - I've never found one!

Hi Lawrence and Everyone,

I was putting away my Aspire parts and I had some washer fluid left in my spare washer res. with pump. I tried poring it into the one in the Aspire and it didn't work well. Bright idea. I hooked 12v to it and it came out like a gusher. I was using a variable power supply and seems like 5v would be good for Zilla and other cooling jobs. What do you think? Lawrence Rhodes

This post hit home. I've been spending the last week trying to find a good set of cooling products to sell on the EV Source site in the Top-Line Shop that would work well with Zillas. I've looked at enough different pumps to make my eyes go buggy. Your idea has crossed my mind. But I don't think those little washer motors are meant to run continuously, and I don't think they would meet the flow requirements (Otmar informs me that 2GPM as listed in the Zilla manual is actually a bit high - 1/2GPM would suffice in most circumstances). Pumps that are doing that sort of flow have 3/8" outputs or larger. The small diameter tubing on the washer motors leads me to think the flow is quite a bit lower than that.

Clyde Warman found a cool reservoir that comes with the Maxi-Jet pumps. I'm most likely going to stock this item - will include the reservoir and pump for around $50. The downside to the Maxi-Jets (aside to their great benefits of longevity and silent operation) is that they run on 120VAC. So you need a small inverter. Someone mentioned awhile back, why not just use a 12V bilge pump? Well I bought a Rule bilge pump for testing. It was quiet, had the flow, but needed to be submersed. No big deal, right? Well try to find a decent reservoir for a pump this size that could easily be mounted in your engine compartment. Not easy (if anyone has any suggestions, I'm open to them). So, I'm going to run with this Maxi-Jet setup. I'll try to put together something that can easily be integrated into any design, and that will be very tempting to those considering their own design due to its low cost. I'm not doing this pump thing to make money - doing it to augment the Zilla controller line. By the way, I was looking into the Swiftech MCP350 pump. I had high hopes for this pump. Otmar about made me cry when he mentioned his reservations about this pump. It only has one bearing, and the magnets keep the other side centered when rotating. Jarring can cause crashing inside. Server racks don't get much jarring, but EVs do. I guess others have had luck using this awesome little pump, but it wouldn't be any fun to ruin a $70 pump in a year of driving.

Keep your eye out for the Zilla cooling section in the Top-Line Shop.

I in fact, am shipping him a mod'ed item of his design out monday.  I'm sure 
that when he has completed his (I have ways of making you talk) testing and is 
satisfied, will post a report.  Untill then it's shhh, shhhhh so don't tell him 
I said anything.   Oh and by the way, I'll be seeking his advise, as well as 
the other main members here as to how best get all the juice out of these 
motors we can.
Just couldnt stand to let you worry about Goldie, and or Rich.  Okay so we all 
worry about Rich, but, hopefully this helps   ;  P
Just a little secret FYI, oh damn did that go to the list?
Hey Rich let me know when you get it

Get it into the 13's and it would dust nearly any street car.. What
would it take? A bigger motor? A Zilla?

Doesn't Jim have any motors?

Put something stout in it and make that thing a terror! ;)

Jim, I find your posts on motors quite valuable. I've been
posting here since 2003 and lurking before that, but never
having built a conversion I still consider myself a newbie
to this. I learn something new each day on this list,
especially from those that delve into the technical aspects
of motors, controllers, batteries, ect.

Aha! Could a new shaft be machined to shrink-fit inside the existing
hollow shaft? This new shaft could accept some kind of "normal" coupler.
Heat the motor in an oven, chill the shaft in dry ice, and push it in
QUICK!

--- Begin Message --- I was able to shuffle some stuff around and head out to Speedworld to support and cheer on Dennis and CE last night and I thought I would pass along what I can remember and decypher from my hastily scrawled notes. Sorry if some data appears missing or is incorrect and any errors are definately on my part.

I arrived just as Dennis was making his first run of the night, he turned in a 12.08 with 100.1 deg batts. 480 battery amps, 880 motor amps. 360V system, btw. Dennis wanted to get into the 11.99s so he tweaked up the motor amps by 8 amps while the batts were getting a drink.

Run 2 - 12.06, reaction time .018, batts showed 102.6 (after the run)
Dialed in another 8 motor amps and had a soda.

Run 3 - 12.036, reaction time .026, batt temp "soared" to 105.0
Another twiddle on the screw for 8 more motor amps, pee break to get rid of last soda. Get lane and competitor assignment for next round at the booth. Change dial in to 11.97 "just in case". Get hit up for $40 for a "Dennis Kilowatt" brick on the Speedworld "ADRA walk of fame" by a busty gal. Dennis being the gentleman he is coughed up the $40 bucks. LOL, SUCKER!! I would like to try this next time I want to redo my driveway but I don't think I have the "build" for it. This was an interesting honor as you couldn't just buy a brick, had to be chosen for it on merits and performance, but the honoree still has to pay for it.

Back to the pits to look at Dennis' charging setup. Very interesting, a LARGE gutted ICE welder, large variac and what looked like a shop air circulator fan. Saw it pump 31 amps into the 360 V pack, charged his car in around 7 minutes. And it charged my Makita drill simultaneously. Dennis said it will go around 28-30 amps up to 480 volts. Hmm. HMMMMM. Too bad its about the size of like 20 PFCs.

A couple ICE doorslammer guys came by and were looking at CE and obviously trying to figure out where the engine was when I let them off the hook and told them it was totally electric. Then one of them saw Dennis checking the data log and controller settings with the palm pilot and asked "what that was for"? I couldn't resist. I told him that electric drag cars were so simple and trouble free that it was so Dennis could relieve boredom and hone his reflexes between rounds by playing Donkey Kong on it. When he said "cool" I almost handed him his sign but instead I quickly laughed and told him that I was just joking, that while evs are really that simple the palm pilot was actually the way Dennis could set the cars electronic motor controller for the next race and view the last runs data. From his glazed look when he walked away I think he liked my first answer better.

Run 4 - 11.98 on an 11.97 dial in, reaction time .036 (getting tired old man :-)? )sheesh I wish I was that "slow", I probably couldn't cut a .500 these days). Totally thrashed the guy he was racing as I posted earlier, Dennis had him so rattled that not only did he red light by like .001 he broke out pretty badly as well.

Interesting thing, immediately after this run the battery temp was only 100.4

While we were waiting for the final run against Nick Alejandre for all the nuggets, some 14-16 second doorslammer turned turtle at half track right across from CE's pit, landed on its wheels and then headed across the track and climbed to a stop halfway on top of the track railing and facing the pits. By the time Dennis and I got to the fence I was kinda chilled as I knew that from the slower class of the car it probably didn't have much safety eq and I was just praying that the driver had a decent set of belts and a good helmet on. He certainly wasn't moving. EMTs were right on it tho and they got the driver out, he was OK!! Shaken but not stirred I guess. Mad as heck. Hope it wasn't his dads car, LOL. They had to get it off the railing with a Ford bucket loader. I told the loader operator to at least blindfold the driver first! But not too much more damage.

Round 5 - Dennis won the coin toss and took the right hand lane. We knocked the gravel off the tires (this track is the only NHRA track I have ever seen that you need mudflaps for) and Dennis belted up, ready to battle for the hand of the fair maiden and the $100,000 first place money. Ok, it was actually like 200 bucks and she wasn't thaaat fair, but you understand the tension. Nick is the current points leader and Dennis is either right behind him in second or very close behind him in third. I think there are only like a couple of points seperating the top 3 right now. Anyway Nick pre-staged, Dennis pre-staged and then staged. Nicks staged light flickered but didn't light, Dennis looked over and then Nick staged, got the tree and Dennis was distracted enough that he cut a .193 to Nicks also dismal but better .103 . Bottom line, CE lost with a 11.999 on a 11.97 dial (112.902 MPH). The race was essentially decided by the reaction time. Man talk about splitting hairs. Dennis lost by .033 differance! I had a guy pull this same move on me once at Pomona years ago (Dennis the gentleman he is doesn't think it was deliberate, me I do) and I actually thought this was long ruled illegal. All in all an exciting night for all concerned. BTW Dennis, somehow that last time slip ended up in MY pocket. Would you care to PURCHASE it? After all a losing timeslip for CE IS kinda collectable, LOL. Seriously I would advise anyone in the Phx area that can to make the time, get to Speedworld and watch CE run for the ADRA crown. Well worth the 10 bucks for a pit pass. And I know that Dennis is certainly instilling a lot of respect if not fear for EVs in the ICE racers ranks. I just wish Bob had made it from CA in time to come with. Bob, wheeeeereee arrreee youuu? Steaks getting mighty cold.
