Trip Reports / Re: Jennings GP track day report
« on: December 08, 2015, 03:56:04 PM »
It was a good weekend...good weather and a chance to meet and share with fellow ebikers. The track is grippy and flowing.
A good time was had by all.

Anyone looking for a break from northern weather, we will do this again Jan 10 and 11.
JenningsGP in Florida.

yes, chilling the battery boxes and nearby frame, etc helps hold off the regen cutback.
It's a bit of trouble, yet effective.
...kinda like everything else in life  ::)

Rochester Institute Of Technology Wins Woodcraft Technologies eMotoRacing Varsity Challenge At NJMP
© 2015, Roadracing World Publishing, Inc. From a press release issued by Arthur Kowitz/eMotoRacing:
ROCHESTER INSTITUTE of TECHNOLOGY wins Woodcraft Technologies' $1000 scholorship at the NJMP 'eMotoRacing Varsity Challenge'

Karl Smolenski completed the 8-lap race on the student-built electric racebike, in an impressive first outing on the ZX636-based prototype.

At the end of last year's racing season, universities from around the US and Canada were invited to compete in the AHRMA-sanctioned eMotoRacing event at New Jersey Motorsports Park July 11-12.

Eric Wood of Woodcraft Technologies, America's road racing gear provider, graciously posted a $1000 scholarship to the winning collegiate team.

Nine teams expressed acute interest in participating, but building a competent prototype electric racebike is no easy or quick task.

Four teams had bikes completed and poised to contend. During final testing just before the event, technical difficulties sidelined most of the teams.

The RIT EV Team stood tall by meeting the challenge, bringing a huge following to NJMP. They were treated to a raucous reception at the evening's award ceremony as the Woodcraft Scholarship was presented.

Isle of Man Manx GP veteran racer Smolenski showed poise with lap times approaching competitve in eMotoRacing's eSupersport class.

The race was won by defending class champion Arthur Kowitz on his Brammo-based streamliner.

Pete Nicolosi of SC led for most of the race, until Kowitz reeled him at the beginning of the final lap. Each rider had sections of the track where they held the advantage, making for an exciting race.

Andrew Cowell came in third, followed by Bob Berbeco of Indiana, and Smolensky on the RIT entry.

Results:

1. Arthur Kowitz Brammo TTX

2. Pete Nicolosi Brammo Empulse R

3. Andrew Cowell Brammo Empulse R

4. Bob Berbeco Brammo Empulse R

5. Karl Smolenski RIT EV prototype

6. Scott Signorini Brammo Empulse R DNF

Brammo Racing / Re: Report on the Brammo/Zero Showdown!
« on: April 27, 2015, 10:16:55 AM »
Willow Spring CA, April 25, 2015

    AHRMA once again hosts the Woodcraft Technologies' eMotoRacing zero emissions road racing series at one of America's iconic racetracks.
   Seven competitors from around the US made the grid on Saturday, for the first of the weekend's two rounds.
   Time Warner Cable TV is on hand to interview the riders and teams, and to cover this exciting event.

   The Hollywood Electrics Racing Team fielded 3 Zero SR based electric racebikes. Jeff Clark, Nathan Barker, and Brandon Nozaki-Miller had practiced the weekend before at this same raceway in preparation for the long awaited Zero-Brammo showdown. Zero SR mounted Doug Smith joined the grid as a post entry.
   eMotoRacing series regulars Murrae Haynes of New Mexico, Pete Nicolosi of South Carolina, and the defending class champion Arthur Kowitz of Daytona Beach, Florida all were riding Brammo Empulses.

   Kowitz' (myself) Brammo TTX sports a carbon fiber fully steamlined body that has helped this fast ebike to pace the field at many previous events.
   However, this weekend was challenged with a US Weather Services Severe Wind Advisory of 36+ hours of prevailing and gusty winds up to 55 mph. Under these conditions the streamliner was difficult to ride at the edges of traction. Consequently, the decision was made to remove the bodywork and race  'au natural'. With this change in configuration came an intermittent power cut out.
 
   As the green flag dropped on Saturday's race, Kowitz gets a sharp holeshot on the field, only to have his bike cut out early on lap one. Three of the well prepared Zeros form an impressive freight train up to the front and proceed to check out on the field. Jeff Clark takes the win with a flawless ride, all eight laps being fast and steady. Doug Smith in second and Nozaki-Miller in third overall.
   The first Brammo finisher was Pete Nicolosi in 4th position overall.
   The light, nimble, and fast  Zeros appear to be dominant, and favorites for the second round on Sunday.

   Sunday's race begins in similar fashion, but motorsports can be unpredictable. On lap 4, Zero mounted Doug Smith crashes in some on track oil presumably left by one of the gas bikes sharing the track. The race is red flagged to care for the rider, and clean the track. The field is sequestered on hot pit road for a 20 minute delay. Now, battery capacity and drivetrain heat become issues. The uncounted warm up lap, the red flag lap, and the rigors of two starts are a concern to all riders as they impatiently await the restart.
   While on the grid, Nozaki-Miller and his team try unsuccessfully to repair a critical broken footpeg mount.
   Clark remains as the man to beat.

   The somewhat heavier, and more complex Brammos have up to now given a little in speed. That is in part due to a water cooled motor, and a complex battery system.

   Upon the restart, predictably, Clark sets the pace on his Zero, with Nicolosi and Haynes on their Brammos in hot pursuit. Haynes is the only bike left in the field that sports a fairing, giving him a potential edge in power conservation, in what is shaping up as a battle of attrition.
   With pressure mounting behind him, Clark must keep up his pace to maintain the lead heading into the final lap. His pace slows dramatically as power wanes. Nicolosi has been stalking and now pounces on the leader in Willow Springs famed turn nine onto the front straight, taking the lead and the win. Haynes also maintains his power and is rewarded a steady 3rd place behind Clark. 

   The next eMotoRacing round is only days away at Sonoma Raceway in Northern California. There are several other teams poised to join these same riders at Sonoma's more technical (and less windy) racetrack.

Brammo Racing / Report on the Brammo/Zero Showdown!
« on: April 21, 2015, 07:50:27 PM »
it"s about time!

http://emotoracing.com/press-release-the-woodcraft-technologies-emotoracing-series-comes-to-california-for-2-back-to-back-events/

The Woodcraft Technologies eMotoRacing Series comes to California for 2 back-to-back events.
 
The big track at Willow Springs will host two eight lap electric road races on April 25 and 26.  Later the following week, Sonoma Raceway will be the site of two more rounds of zero emissions racing, April 30 and May 1.

A three bike team sponsored by Hollywood Electrics of Los Angeles will pit specially prepared Zeros against the Brammo Empulses that have dominated the series in 2014 and so far into 2015.
Riders Jeff Clark, Brandon Nozaki-Miller, and Nathan Barker will pilot the Zero Team.  Brammo riders include Pete Nicolosi of NC, fresh from a win at NOLA, Murrae Haynes of NM, and defending series champion Arthur Kowitz on his solar powered streamliner.

Last year's winners at Willow Springs was Dave Roper and Arthur Kowitz. Winner for both races last year at Sonoma was Eric Bostrom.

Later in the season, the eMotoRacing events at Miller and NJMP will showcase prototype road racers built and campaigned by university student teams. These teams will compete against the Brammo and Zero production based bikes.

For additional information on this ground-breaking series, visit eMotoRacing.com and on www.facebook.com/eMotoRacing

another all Brammo field, Zeros again absent....pics on Facebook at eMotoRacing.
I feel sure there will be well prepared Zeros at the round at Willow Springs CA.
Looking forward to it!

Brammo News And Views / Re: Why the Brammo hate from other electrics?
« on: March 10, 2015, 11:12:19 PM »
I am a fan of electric motorcycles...Zeros, Brammos, conversions, prototypes, or whatever...and I love racing.

As far as racing improving the breed...with first hand experience, I can say the Brammo racing program has directly influenced a Parker built motor with different windings, that is faster and more energy efficient than the earlier version.
This is not the only item, merely an example to share a specific instance where Brammo has made improvements in the past 2 years.
This newer motor works better with the standard Sevcon controller than the earlier motor, and is standard in the most recent Empulse Rs.

The Zero racebikes on the FIM grid of 2013 were testing technologies, witness the presence and involvement of several of their engineers. We expect to welcome more Zeros in the eMotoRacing series in 2015.
Quite a few more university prototypes are also on the horizon.

Everyone is working to improve their bikes...Brammo, Virginia Tech, Zero, Kennesaw State, etc, and privateers like myself. Just because strategies vary doesn't mean nothing is happening.

Lets support each other, advance the technologies, and make the bikes and the sport better.

Victory Empulse / Re: Input on Charger Design
« on: March 02, 2015, 03:22:06 PM »
yes, that is my streamliner 'rocketing' away...nice choice of words.
The longer the track, the greater the advantage. However, even on the shorter courses it is an advantage, albeit small.
I ran the same bike unfaired, then with a Ninja fairing, and now the full streamlining.
Top speed figures with the same motor, batteries, controller went from 108, to 117, to 126.
As mentioned before, each time I reduced wind drag the energy consumption also went down.
Since you saw the bike at Barber, I have replicated the original fiberglass test model in carbon Fiber. The weight of the nose fairing went fromn 20lbs to 6lbs.
It is very nice to ride with 14lbs removed from the front wheel.

There is an elephant in the room!

We saw in the video, the faired bike outrun the naked, what you couldn't see very well was my streamliner outrunning the conventionally faired bikes., and had more energy left after the race.
It isn't a fashion show, it's racing.

If form follows function, we'll see more streamliners on the track, and maybe someday on the street.
Faster and more range.

Brammo Racing / Re: eMotoRacing at Roebling
« on: March 01, 2015, 12:30:50 PM »
I was carrying 5th until on the front straight, tried the short shift a couple of times but felt like I had more control while leaned over and driving out while in 5th.

BTW, IMO Roebling rewards drastic late apexing everywhere, emphatically drastic.
