Swamp Rat 37 builder, Shawn Lawless' first hand account of Don Garlits' latest attempt at 200 mph
NEDRA NEWS - Bradenton, FL (June 7, 2014) "Big Daddy" Don Garlits attempted to break 200 mph over the weekend but just fell short of that goal following a brush spring failure.
Here is a first hand account from Shawn Lawless about the weekend's amazing attempt at Bradenton Motorsports Park. This incredible account shows just what's involved to go after 200 mph on electrons. Shawn's company, Lawless Industries, is overseeing the electronic drive components of Don Garlit's Swamp Rat 37 dragster. Click on the photos for larger images.
Shawn Lawless: First some things we learned from the previous test on April 30.
The tranny reverser was no match for the motor torque. Don removed it entirely for this test. The low ratio was changed form 1.40:1 to 1.45:1
The rear end pinion was twisted from the massive torque. Don replaced the 3.50:1 ratio 3rd member with a much stronger Pro Gear 3.20:1 ratio unit.
The motors were pristine though the 630 chains were stressed after 8 launches. We upgraded the chains to the same 630 EK drag bike chain that we use on Rocket and replace the synthetic oil in the chain box with a special
coating fluid Don uses in his rears.
Everything else on the Lawless side was the same as the first test.
Run one, 8.243 @ 160 mph. 75% power
Smoothest run to date. Getting rid of the reverser, Don's custom pro gear and setup, and the EK chain all contributed to a reduction in driveline slop. Post run inspection showed everything 100%.
Run two, 7.52 @ 173 mph:
Power was increased to just below max level battery current and to max motor voltage.
The motors are in a series wiring setup with each pair splitting the max motor voltage. The motors are good for 225 volts each but controller voltage is limited to 425 absolute max and 400 at full power. In an effort to get the most out of the motors at the top end the batteries were charged to their maximum of 420 volts. Previously we had only charged to 410. The idea was that some voltage would "burn off" during the massive burnout at the line. Unfortunately Don reported that when he went to burnout the car had no power and felt like it shut off completely. Don drove the car from the line back to the pit where we uncovered and inspected all electrical system components. All checked out good. A phone call to Otmar confirmed that we had indeed charged the batteries to far to a point where the Zillashad cut back the available motor power to almost zero to protect themselves.
That was good news and bad. We had no way in the pits to bleed off the excess voltage so we sent Don on a loop that went down the strip and back the return road. By mid track the voltage had dropped to allow for some real power and Don finished out the run hard. One the way back he added some massive burnouts on the return road to further bring the voltage down closer to 400 volts. We brought Don straight around to the burnout pit and he did another big burnout. At that point I saw some sparks under the car but that is nothing I haven't seen periodically on any of our other machines during abig burnout. We discussed the sparks quickly before Don staged but at that point there was no going back to the pits and delaying the run again. The people in the stands came to see the car run not us looking at it. I told Jeff Garvin who was crew chief to send Don down the track. Just before Don shifted I saw a few sparks from the car then it was all good to the finish. Don told me after the run that he stayed in low a bit longer than he had been until he felt acceleration starting to slow then shifted and the hard acceleration returned and stayed good through the 1/4 mile. The crew at the top end saw a bit of smoke from the car. Initial inspection at the top end revealed no fire so we towed the car back to the pits and stripped off the covers. All wiring looked good. All batteries looked good. All Zillas looked good. All motor brushes, coms and holders looked good till we found the source of the smoke and sparks. What was left of a melted motor brush spring was stuck in the vent cage of motor number 4.
Amazingly the brush was still in place! As everyone was waiting for answers we searched for a way to replace the brush spring and get back to the track but the tight design of wedging 6 motors into the chassis made it impossible to replace without removing the motor. On SW-37 this is a 4-5 hr process and it was a day killer on Sunday as there was no point in running the car on 5 motors or even on 6 motors minus every single brush. I broke the news to Don and he broke the news to his admiring fans in the pits, who to my surprise all applauded the effort! He is truly one loved racing legend!
I talked to Otmar post race and learned one more nuance of this sport. I had set the rev limiter to 8000 rpm to protect the motors during burnout. It turns out that by doing so I did more harm than good. Otmar informed me that when up against the rev limit the Zilla turns on and off at full power. So during a big time burnout at the rev limit the motors are subject to huge pulses of voltage and current several times a second, much more abuse than they ever see anywhere else. We know from experience that the 7.5 GE's can rev well past 10,000 rpm during burnouts without incident but I wanted to be conservative and set SW-37 at 8,000. The huge amount of power spikes heated the motors and brushes up to the point that the weakest spring couldn't take it and melted of and bounced around motor 4 com causing the sparks and smoke we saw. Interestingly, though all other motors and even the brushes and springs in number 4 were all in perfect shape except for the one that I now hold the remnants of!
I talked to Don this morning and have set a plan in place for the following:
Raising the rev limiter to 10,000 rpm.
Adding a third "burnout" position on the power switch which will limit voltage and current during burnouts while keeping the motors off of the rev
Building a battery load bank and using it to cycle and drain batteries instead of using the drive system to do it. Lithionics Battery in Clearwater, FL has joined the SW-37 team and donated all of the massive locomotive resistors needed to build the bank!
Adding 3 Zillas so that the motors can get max voltage of 225 without pushing the battery voltage over the 400 volt threshold.
The Lawless team will complete this work and get Big Daddy back in the car sometime in July, just before the 50th anniversary of his last 200 mph first!
"Big Daddy" Don Garlit's breaks long standing NEDRA Record
NEDRA NEWS - Bradenton, FL (May 3, 2014) "Big Daddy" Don Garlits broke Dennis Berube's long stading NEDRA DR/A3 record which stood unchallenged since 2007. Dennis' record at the time was 7.953 seconds at 159.85 mph.
Don's official NEDRA record breaking run
at Brandenton Motorsports Park May 1 was 7.526 seconds at 178.42 mph when Don and his crew were making test runs with the dragster.
The DR/A3 record is for dragsters with a nominal voltage of 408 volts which is a measured voltage between 382.9 volts and 448.8 volts. Dennis' voltage was 390 when he made his record in 2007 and Don's voltage was 409.
NEDRA records require at least 2 runs and the ETs must be within 1 percent of each other to take the best ET.
Don will be taking the dragster out again in June for a go at 200 mph. He was the first to take a dragster to 200 mph in the 1/4 mile and now wants to go 200 on electric power. Initial goals for the car are 6 second 1/4 mile passes at 200 + MPH.
When Dennis found out his long standing record was broken by none other than "Big Daddy" Don Garlits he was thrilled.

Kristen Stacy puts the
Hammerdown and breaks a
new electric dragster record!
NEDRA NEWS - Richmond, VA (May 2, 2014) Kristen Stacy is showing the guys how to put the "hammer down" at Richmond Motorsports Park with a new NEDRA DR record of 7.89 seconds at 161.87 mph on her second run of the night! Click the photo above for a larger picture of Hammerdown's burnout.
Kristen's warm up run was 8.81 seconds at 142 mph. Her back-up run was a respectable 7.940 seconds at 159.80 mph. The 7.89 record makes Kristen the quickest woman in an EV to hit the drag strip. Check out the video of Kristen's 159.80 run.
Hammerdown features the one and only Zilla Z4K in existence. Yes, that's right. A 4000 amp speed controller which was producing over 3000 Amps for these runs! Who knows what it could do a full power!
Hammerdown is an electric dragster built by Lawless Industries who also built Don Garlit's Swamp Rat 37. Hammerdown, when it was called Matrix, was featured in an episode of Top Gear in the 2013 season. With Kristen at the wheel and her top notch crew at Lawless Industries we can expect to see more records this racing season.
Big Daddy Don Garlit's tests Swamp Rat 37 and breaks 180 mph!
NEDRA NEWS - Bradenton, FL (April 30, 2014) "Big Daddy" Don Garlits took it to the pavement and blasted Swamp Rat 37 to a best test run of 184 mph Thursday at Bradenton Motorsports park in the "Quest for 200 MPH on Batteries."
The dragster arrived at the track with High Tech System's brand new uncycled lithium battery packs. So Don ran a couple warm up runs to get the electrons moving. The first was 10.05 seconds at 129 mph on 33 percent power. Next warm up run was 8.74 seconds at 150.95 at 50 percent power. They decided to crank it up the amps more but blew a couple 800 amps fuses. After dialing down the amps, Don ran a 7.526 second run at 178.42 mph with power at less than 90% then a last run of 7.258 seconds at 184.01 mph after no charge and hot lapping after an 1/8 mile burn out while trying to run opposite lane. The GE motors didn't even get warm. 200 mph is just around the corner.
Many NEDRA members who are part of the SW-37 crew and to witness the event were there. Helping to turn some wrenches was NEDRA Vice President Lowell Simmons, Jeff Disinger who was part of the team that inspired the idea of SW-37 helped in the pits, Tim Meehan, a former Lawless Team driver, Bob Salem was there with his NEDRA hat to support the crew and former NEDRA President Shawn Lawless whose company, Lawless Industries, designed SW-37s electric drive system and has been an integral part of the build from the beginning.
The dragster uses components built and designed by NEDRA members including Otmar Ebenhoech's Manzanita Micro Zilla 2K controllers that Swamp Rat 37 uses 3 of. The 1.5 megawatt battery pack was designed and built by NEDRA sponsor, Derek Barger of High Tech System. Derek has supplied many of NEDRA records setting racers with custom lithium battery packs over the years. And of course Rich Rudman whose company, Manzanita Micro has been a vital part of the project in supplying parts.
The idea for SW-37 was the brainchild of Don Garlits and Mike Gerry with Mike's excellent dragster building skills. It would not be possible without the support of the following sponsors:
Brad Hadman Race Cars
Don Garlits Museum of Racing
High Tech Systems
"Big Daddy" was the first to take a car to 200 mph in the 1/4 mile and now wants to go 200 on electric power. Initial goals for the car are 6 second 1/4 mile passes at 200 + MPH.
Big Daddy Don Garlit's
to test race Swamp Rat 37
NEDRA NEWS - Ocala, FL (April 29, 2014) "Big Daddy" Don Garlits and the Swamp Rat 37 "Quest for 200 MPH on Batteries" EV Dragster will have a full systems test on April 30 in at Florida's Bradenton Motorsports Park. The test is open to the public for a nominal $10 facility fee.
The SR-37 team will converge today at "Don's Garage" at the world-famous "Don Garlits Museum of Drag Racing" for the final installation of the battery pack and integration of the motors and Manzanita Micro "Zilla" Controllers. Garlits will be joined by battery engineer Derek Barger of HighTech Systems LLC who recently completed the incredible 1.5 megawatt 2014 SR-37 Lithium Polymer battery package. Shawn Lawless of Lawless Industries will be on hand to tune and tweak the 6-pack of GE motors furnished by Crescent Electrical Supply Company.
The Quest Dragster is designed and constructed to be the first battery-electric dragster to exceed 200 mph on a quarter-mile drag strip. The dragster will be powered by a 1500-kilowatt array of lithium polymer (LiPo) batteries producing an equivalent horsepower rating of over 2,000 horsepower.
The Quest for 200 MPH on Batteries dragster was built by Brad Hadman, created by Mike Gerry with art direction by Kenny Youngblood, car and logo graphics by Eric Reyes and print graphics by Tommy Naccarato.
Congratulations to all the NEDRA members who are a vital part of this project.
Lowell Simmons puts the Hammerdown in the 8's and gets his IHRA License
NEDRA NEWS - Palm Beach, FL (March 30, 2014) Mirmar High School Automotive Instructor and NEDRA racer, Lowell Simmons earned his IHRA License this past weekend at Palm Beach International Raceway doing the five required runs using the Lawless Industries Hammerdown dragster.
After racing the five runs for the license, he put the Hammerdown for a high-seven to get an electric dragster record. Unfortunately, the ET was another 8.37 second run, same as the previous one, with the same 1.15 second 60' time at 148.7 mph. But the season is still early and there will be more opportunities ahead.
Matt Graham's "Joule Injected" Nissan SX comes out of retirement and blasts an 11.7
NEDRA NEWS - Palm Beach, FL (March 30, 2014) Matt Graham's Nissan SX is no stranger to the drag strip. In 2006 the SX blasted through the traps at just over 100 mph! But with twins on the way and other commitments, the car was garaged. Matt later had the students at Miramar HS upgrade the car under the direction of Automotive Insruction Lowell Simmons with upgrades including a fresh 400 volt lithium battery pack and cleaning up the dual motor Warp 9s fed by two 2k Zilla speed controllers. Lowell took it for a test spin at Palm Beach International Raceway and blasted down the quarter at 11.7 seconds at 104 mph which is just as quick as a Tesla Model S!
Matt, Lowell and the kids at Miramar HS are to be congratulated on this awesome achievement.
John Metric Breaks into the 8's
with his electric Miata
NEDRA NEWS - Baytown, TX (March 15, 2014) Breaking the 8's has been a goal electric drag racers with street based electric cars also known as "door slammers" have been attempting to achieve for quite awhile. John Metric finally did it with his electric Miata, Assault and Battery Friday night at Royal Purple raceway with a 1/4 mile time of 8.913 seconds at 147.99 mph. It's also the first doorslammer to break 125 mph in the 1/8 mile!
Here is John Metric's on the scene account.
We went to Royal Purple Raceway in Baytown instead of HMP due to rain in Houston. The nearly 2 hour drive and showing up about 1.5 hours late paid off.
lately we have been running with both zillas maxed to 2000amps and motor volts at 210V.
This clips the zilla power limit back to about 1700amps near 200V. The only real adjustments we have been making is to the stance, four link pre-load and spring heights. It has made a huge difference. The car finally is getting the front end in the air and it is not twisting the chassis over on its right side anymore. It was leaving nice and straight on a test-n-tune night.
The warm up run was 9.364 at 143.16mph 1.47 60ft at 15psi.
Second run, only change was we dropped to 13psi, we left really strong but right about the 1/8th mile at 120mph both controllers tripped and I coasted down the track. But they came back after the race. It was like an overspeed protection, I will have to check the sensor. Not sure what happened. However, That run was 9.379 at 120mph
Third run only change we made was to drop to 11psi. The car raised up on its rear tires and felt really good.
So in summary, for a short day, nearly a rain out. Assault & Battery blasted past the 9.0 second barrier and posted a 8.913 147.99 mph.
First door car in the eights (ET Club), first door car over 125mph in the eighth(Roger Hedlund Club), and we will apply for eighth mile record 5.730 126.26mph.
Thanks to all the folks that make it possible.

Assault and Battery Sets New 1/4 Mile Record at
9.12 Seconds at 145 mph!
NEDRA NEWS - TEXAS (October 11, 2013) NEDRA President John Metric took his Miata, Assault and Battery to an all-time 1/4 mile record for a door slammer at Royal Purple Raceway with a best time of 9.12 at 145 mph!
John ran Assault and Battery with a newly installed 333 volt LiPo pack and two 2000 amp Zilla controllers feeding dual NetGain 9-inch motors. For the first run, John was conservative and set the battery amps to 900 on both speed controllers and sag voltage to 300V.
When he approached the line he accidently knocked the line lock switch off its mount so he had to do the burnout the old fashioned way. At fir,t the car spun the wheels off the line but caught traction a fraction of a second later. John kept pulling it straight and made it down the track. Just for kicks he pulled the parachute and turned a respectable time for his first run which was his best time so far with the car.
The new pack stayed strong and beat the Mustang by .01 seconds.
With a 9.5 run in his sights and the pack warmed up which should gain more HP, John deflated the tires a couple PSI to gain more traction. He told his crew he was planning to leave the Zillas set at 900 amps but John's son yells, "900amps, 900amps, I didn't come all this way to run 900amps." So dad, raised it to 1100amps. Unfortunately, the battery charger was having some programming issues so John was only running the charger at 1/3 power so he charged the lithium batteries the best he could before the second run.
To add some drama to the evening John's Miata danced off the line on it's second run. He had a good burnout, but the front tires went up in the air and the car pirouetted and took a hard right turn directly towards the truck in the other lane. When the wheels came back down the car jerked violently back to the left, but he was able to gain control.
Back in the pits John's crew lowered the tire pressure some more, fixed the line lock switch holder, decided to try to feather on the power with his foot versus just mashing it. Another hour goes by and they head up to the front again for the third launch. John figured he had two good runs left fot the night.
At the line John does a massive burnout and with the latest settings pulls a 9.1!
John deploys the chute for kicks and beat a black Mustang this time.
At this point John is contemplating the eights but decides not to get greedy with the settings and leaves everything where it is and try another run.
With five minutes left before the track closes John makes his fastest past ever.
John has a new NEDRA XS/A2 Record. He would like to thank his crew and fellow EV enthusiasts who came out including Nathan Metric, Adam Clark, Kevin Douglass and wife, Keith Howard and Wife (who both drove their EVs.

Electric Jr.wins his Age Class on his Second day on the Track!
NEDRA NEWS - OHIO (July 13, 2013) Eight year-old Mark Dubiel Jr. won the Quaker City 8-9 year-old class in the Lawless sponsored Jr. "Bat Mobile." powered by 56 volts of Milwuakee power tool batteries! This, on only his second day of racing!
Mark wasted no time getting to it. Running in the 8-9 year old 11.90 class at Quaker City in a class of 10, Mark posted consistent runs of 12.42, 12.43, and 12.45, cutting a near perfect reaction time of .0017 on one of his runs. He won his first elimination round with a light of .0735. He also made a NEDRA record in the JR/CH class.
The "Battery Mobile" or "Batt Mobile" was built by Mark's dad and his grandfather with some help from Shawn Lawless. Mark's grandfather, a dragracer himself, helped procure a trailer and components for the car which was a retired Spitzer Jr dragster from a racer at Quaker Raceway.
The batteries are 28 volt Milwaukee power tool batteries wired together in parallel and in series to produce 56 volts. Mark's dad is an electrical contractor so the Milwaukee batteries were the perfect choice for the car. They can make several runs without a recharge. The car used only .02 volts per run!
Shawn Lawless provided a permanent magnet motor and technical advice for the project. The motor controller is Curtis from a 48 volt golf cart. Pretty simple in design but effective on the track!
Bill Dube and Eva Hakansson Builds Lithium Battery Pack for Drayson Land Speed Record Lola
NEDRA NEWS - ENGLAND (July 1, 2013) Lord Paul Drayson broke a long standing electric land speeed record at RAF Elvington in Yorkshire, England, smashing the previous record of 175 mph set by Battery Box General Electric in 1974. Lord Drayon drove the Lola B12/69 EV electric race car to a top speed of 204.2 mph at the racetrack over a course 1.86 miles.
The Lola was running on an A123 Systems battery pack designed and fabricated by NEDRA Members Bill Dube and
"We designed and fabricated the main (rear) pack. Then Eva and I taught the Drayson engineers how to fabricate battery packs. They then built a supplemental center pack for extra added capacity they needed for the land speed record," said Bill Dube soon after the record run.
The battery pack Bill and Eva helped build for the Lola B12 uses a 30-kWh lithium-ion battery from individual A123 cells to deliver 850 hp with a single-ratio transmission. The car has customized Rinehart motor speed controllers and Yasa motors.
Bill and Eva have several years experience building packs using A123 batteries which has been used for their record setting bike, KillaCycle, and their latest project, KillaJoule, a land speed racing streamliner motorcycle. They will be racing KillaJoule August 24 at the Salt Flats in Bonneville. Drayson will be gearing up for the FIA Formula E Championship in September 2014.
TC9 Hornet Breaks 1/8 Mile Record
NEDRA NEWS - DENMARK (July 11, 2013) True Cousins, Glenn E. Nielsen and Hans-Henrik Thomsen took their TC9 Hornet to a new 1/8 mile record for the 300 volt class Wednesday evening at Malmö Raceway with a record run of 7.07 seconds.
The previous record was 7.63 seconds. Glenn drove the TC9 Hornet through the 201 meter track at 7.40 and 7.58 seconds in the first two runs, below the old record but a little slower than they had hoped.
After making some adjustments by letting the air out of the rear tires for better grip and turning up the amps in the last two runs, they clocked a 7.07 and a 7.01 for the new 1/8 mile record.
The next goal for True Cousins is to compete in the 350 volt class where they hope to break 6 seconds in the 1/8 mile.
Miramar High School's Black Pearl
Breaks Into the 9's!
NEDRA NEWS - FLORIDA (June 15, 2013) Miramar High School Auto Shop Instructor, Lowell Simmons, took the school's 396 volt Porsche 944 to it's best time with a 9.952 second 1/4 mile at 130.90 mph beating a tubbed out turbo Supra. Despite a few Gremlins early on at Palm Beach International raceway Lowell was able to make five solid runs leading up to the Porsche's quickest time ever.
The first pass was a 10.565 and left a Dodge Challenger at half track when Lowell hit the line. Second pass was 10.115 @ 129.92 and was a bye run getting all so close to 9 seconds. Lowell learned how to play the game and waited for a car no one wanted to run then sneak into the opposite lane. Lowell figured his work was cut out when he looked over and saw the chute on the back of the Nova in the next lane. Lowell cut a marginal light .159 and left the Nova at the Gremlins caused the overdrive not to shift so only toped out at 122.28 but still ran 10.105. So close to the 9's. Now time for one more pass, no one wanted to go up against a big turbo tubbed out Supra, so Lowell took the chance. He cut a .045 light still only a 1.525 60' but then Black Pearl came to life. Crossed the line at 9.952 @ 130.90 beating the Supra's 10.946. Black Pearl was the fastest street car at the track.
Not bad for a daily driven 2910 lb full interior car with power windows built by a high school students. Lowell's next step is to get his license and certify the car's cage so he can continue to race into the 9's.
Lowell is very thankfull for the help getting the car to this goal. The Derek Barger High Tech Systems cells which make up the 15kw, 396 volt battery pack. Running 2 zillas each set at 1200 battery amps. 1 transwarp 11 and one warp eleven coupled to gear vendors overdrive. Gearing and suspension are the second best factors, running a 2.75 gear set right out of the junk yard with aNodular carrier on a Strange spool in a big bearing Ford 9 we narrowed and welded to a 4 link set up. Using advice from the school's physics class, the 4 link intersects at mid door so the car launches straight, front end raises only slightly. 275 60 15 Micky Thompson drag radials stick. Lowell proudly displays his Zilla Powered sticker in the rear quarter windows! High Tech Systems, Zilla power, and Manzanita Micro Charging: nothing finer in the world in Lowell's book!
Brandon Willmon defends 3-week winning streak with his Jr Dragster
NEDRA NEWS - ALASKA (June 11, 2013) On June 9th, 2013 Brandon Willmon defended his three week winning streak in his Electric Powered Junior Dragster (EPJD) at the local IHRA Track, Alaska Raceway Park. He is currently leading in the point standings. This marks the second year that the NHRA and IHRA have allowed electric Junior Dragsters to compete alongside their gas counterparts for official National Competition in their respective Junior Dragster Series. Brandon's dad converted this particular car, Munky's Ride, to electric several years ago for Morgan Carter, the track owner's granddaughter. Morgan is old enough to be getting into a "big car" now and so Brandon's dad bought the car from her parents. Brandon and his brother Spencer qualified for their IHRA Competition license last year in 2011 before an unfortunate accident rendered the motor inoperable. Pics of the rebuild can be seen on TheFoat site. Over the winter their dad rebuilt a $50 motor which was a pulled out of a wrecked forklift. The original conversion of this car was powered with a 12V Prestolite motor exactly the same as the late Father Time's Franken Dragon bike and a Logisystems 72V 1000A controller. It now sports a rebuilt ADC AT4-4001 6.7" motor and a Zilla 1K controller. It is still running the original Enersys XE-16's (same as the Odyssey PC-625's, and same batteries the likes of the White Zombie made it into the 11's with in the 1/4 mile) it was converted with 5 years ago. The car originally ran 10.90's in the 1/8th mile. Now with the new ADC AT4-4001 and Zilla 1K it is running consistent 10.9 times at 60 mph but with data logging capability. It is apparent now from the data coming in that the Enersys XE-16's are the limiting factor as to the ET and Trap Speeds of the car. But for Bracket Racing it is still a deadly consistent car. Brandon is calling his own "Dial In" times based on the T&T runs. The competition with the gas cars is fierce as you might see from some of the time slips. So far the winner of last year's season is dialing withing 100'ths of seconds. Brandon has won two of his final runs by "breaking out less than the competition" by hundredths of seconds. All-In-All this is a good day for the electrics around the world. We know there are other electrics out there and what a great day it will be when its EPJD Vs. EPJD in the finals.
