Very nice article about KillaJoule's visit at The Maine School of Science and Mathematics:

--- Loring track over 2.5 miles long ---

Blog - in EnglishPosted by Eva Håkansson 18 Jul, 2012 01:01:35
Just to clarify, the Loring AFB land speed race track is over 2.5 miles long, of which 1.5 miles is used for acceleration and just over a mile to slow down.

Stopping in 1 mile doesn't sound like a challenge, but it is! If you don't stop in time, you better bring your passport because you will end up in Canada. ;-)

If you want to learn more about the fantastic Loring event, check out their website www.lta-lsr.com. There are holding another event at Loring August 31 - September 2. Be there or be square. :-) (Sadly, budget will not let us make more than once to Loring this year).

--- Fantastic land speed racing in Loring! We are coming back! ---

Blog - in EnglishPosted by Eva Håkansson 16 Jul, 2012 06:55:11
Loring is definitely _the_ best land speed event in U.S. Great track (1.5 mile run-up, 1 mile to slow down, paved), fantastic people and great weather (not at all as hot as Bonneville). We have had a great weekend!

KillaJoule ran mechanically absolutely perfectly. It ran straight as a string, stable and strong. Chutes, tires, steering and all other critical components worked flawlessly. Except for the sauna heat and the more than slightly claustrophobic feeling of being strapped on my back in a pop-can going almost 200 mph, it is quite fun to drive. The race organizers were really impressed with both engineering and behavior on the race track. Many new vehicles don't run well, if they run at all.

Unfortunately, a software problem made it shut down if I held full throttle for extended length of time. We believe that we have made a mistake while setting up the extremely sophisticated Rinehart motor controllers. These are state-of-the-art AC controllers and have a large number of parameters that can be tuned to give exactly the throttle response and behavior we want. If these parameters are set so they conflict, it can result in an unexpected shut down. We couldn't figure it out on the track, but we are quite sure that it is simply a stupid little mistake somewhere in the setup. Except for that user-error, the Rinehart controllers and the gorgeous EVO motor work wonderfully. The A123 Systems battery pack provides the needed power very reliably.

KillaJoule is definitely capable of going well over 200 mph, but when I couldn't hold full throttle, we simply couldn't reach it with the current setup in such a short distance at 1.5 miles. If we had been at Bonneville with 3 mile run-up, it would have been no problem.

Our best speed was 188 mph in the 1.5 mile and 164 mph in the 1 mile (1 mile and 1.5 miles are measured on the same track, so you can set two records in one run). Since electric voltage classes were added this year at Loring, all the electric classes at Loring had open records. 188 mph and 164 mph are thus the new records in the SCS/E-349+ class (Sidecar streamliner motorcycle - Electric - Over 349 volts). 188 mph is also, to my knowledge, the highest speed recorded for an electric sidecar motorcycle in the world. It is bit left to the overall sidecar record of 219 mph, but we are making good progress. Not too bad for a garage team working in the spare time. ;-)

Having a great time at Loring. Most racer-friendly land speed event imaginable. Most sensible, thorough and friendly tech-inspection we ever had. As any Bonneville land speed racer will tell you, tech inspection is in best case painful and can be horrible. Not so at Loring. They want you to be safe, for sure, but they are not out to prove how smart they are or how stupid you are. Totally professional. No big egos. We are definitely coming back.

Track is great and they are doing their very best to efficiently get as many racers down the track as possible. We have lost count how many time the race officials have come by and asked us with a smile "Is everything going OK? Are you having fun?".

All the local racers have come over to welcome us and introduce themselves. Including the Bill Warner, the world's fastest man on a sit-on motorcycle (311 MPH, last year here at Loring).

The only thing that hasn't been perfect is the weather. Racing started a bit after noon and we only got our "Rookie" run at partial power before it started to rain. However, 139 MPH was a perfect shake-down and we are ready for full throttle tomorrow.

Video: "Monkey's" eye view of 139 MPH Rookie/Licensing run.
Well, KillaJoule has lead plates a GoPro camera instead of a "monkey" on the sidecar, but this is what you would see if you were the sidecar passenger (a.k.a. "monkey").

--- 0 to 100 mph in 6 sec. Drayson B12/69EV - the KillaCycle team designed and built the pack---

Blog - in EnglishPosted by Eva Håkansson 09 Jul, 2012 01:54:03
Video clip of testing of the Drayson GT race car B12/69EV at MIRA facility in England. (If you are in a hurry, start at 1:13 min)

This car clocked zero to 100 MPH in 6 seconds, with very conservative software limits in place for these initial tests.
Drayson has a lot planned for the B12/69EV GT car, so stay tuned.....

The KillaCycle team designed and constructed the battery pack for this vehicle. Mavizen put us together with Drayson and worked all the
logistics. Derek Barger pitched in to help with a portion of the fabrication on this huge pack made from A123Systems cells. Bill did most of the design work, while Eva did most of the fabrication work on the pack.

Some links to more information about the car and about Drayson Racing

Mavizen: http://www.mavizen.com/

This pack uses the new upgraded version of the A123Systems 26650 M1 cells (Called the "M1B" model 26650, not to be confused with "B grade" cells.) In addition to the nifty black stripes printed on the end of the cells, they have more than 10% higher power output and about 10% more energy content in the same size cell. The M1B cells each weigh a touch more than the standard M1 cells.

--- KillaJoule racing in Maine July 13-15 ---

Blog - in EnglishPosted by Eva Håkansson 30 Jun, 2012 20:56:51
The next race for us will be at the old Loring Air Force Base in Maine on July 13-15 (tech inspection July 12).

This race is slightly different from Bonneville. At Bonneville you have about 3 miles to get up to speed and then you are timed over a flying mile or flying kilometer, and your official speed is the average speed over the mile (or kilometer).
At Loring you have a 1.5 mile paved track (the old runway) with a standing start. There is a speed trap at the 1.5 mile mark and that is your official speed. It is more like a long drag race but your MPH is recorded instead of the ET (elapsed time).

If you want to come and see us, racing starts on Friday July 13th at noon and ends on Sunday 15th at 4 PM.


--- KillaCycle back on track with new record! ---

Blog - in EnglishPosted by Eva Håkansson 08 Apr, 2012 22:33:23
KillaCycle is back on track with a brand new battery pack, and started the season by setting a new, minor record.

KillaCycle had its season premiere today at Bandimere Speedway, Denver, CO. Piloted by Pro-Stock rider Scotty Pollacheck and with a brand new, prototype battery pack with A123Systems "Formula 1" cells, KillaCycle is back into the 7's. A brand new, lightweight, and ultra sticky M&H Racemaster tire gave the necessary grip.

The new pack weighs 70 lb, has a voltage of 264 V and puts out about 600 HP. The "Formula 1" cells are manufactured by A123Systems and were developed for the Formula 1 KERS (Kinetic Energy Recovery Systems). They are the most powerful battery cells ever in series manufacturing.

The lower voltage puts KillaCycle in the lower "A" voltage category instead of "A3". The new pack has made KillaCycle 148 lb lighter, and it weighs now 505 lb instead of 653 lb.

Scotty did a 8.159s @ 166.66 MPH (268 km/h) and backed it up with a 7.984s @ 174.48 MPH (280 km/h). This is makes it the new record in the NEDRA DMC-A class (Drag Motorcycle, 241-300 V). The record will be the slower 8.159s @ 166.66 MPH time since there is more than 1 % difference between the two times. The record in this class was previously held by Jeff Disinger with the "Predator" bike. (The new record is still pending ratification from NEDRA).

Thanks to Boulder Nissan that organized this pre-season track day and thanks to Sporty, Jeff, Larry and all the other Bandimere folks for the awesome track prep!
