Hey guys. Pretty cool place ya'll have here. I found the YB when I was searching for something else golf cart related and came across the YB golf cart races so I thought I'd join in and show off my golf cart stuff.

I got my first cart a few years ago just to run around my neighborhood and immediately started trying to figure out how to make it faster. We use this for a pit cart now. '07 EZGO. 48 volts, all air suspension with onboard compressor and tank and a bunch of custom stuff, roll cage, bumpers etc... that my buddy and I built for it. Runs 43mph.

http://farm8.staticflickr.com/7422/10564442014_9f1502a346_c.jpg (http://www.flickr.com/photos/[email protected]/10564442014/)

That just wasn't fast enough so I bought a rolling chasssis drag cart from a guy in Florida that used to build these chassis. 90" wheebase, all 4130. Golf cart rear end. Running junior dragster wheels and tires, rack etc.. Has Wilwood brake pedal and m/c with atv calipers and custom disks. Was set up to carry 12 - PC680 batteries for 144 volts.

Here's what we started with...

My buddy Bob that built the custom stuff for the pit cart is an aircraft fab guy in real life and the dude can make just about anything out of a piece of metal so I enlisted him to do his magic on the drag cart as well. He's done lots of chassis stuff for me in the past for string of Pro street cars that we built in the 80's and 90's. Bob fabbed structure onto the existing drag cart chassis for more batteries and such and built a custom body from .040 aluminum and mounts for the golf cart bodywork. We used the stock front cowl and rear body sections and just modified them to fit.

Here's the new rear chassis work...

And the body being fabbed...

Here's the electronics going in. The left side pod holds the fuse box, traction pack fuse and contactors along with the PC680 that runs the electronics. The center section of the chassis right behind the driver compartment holds 12 - PC680's. The controller is a Manzanita Micro Zilla 300volt/1000amp unit that we ran in 2013.

Here's everything together for the drive system. 4 additional 680's are mounted in the right side pod for 192 volts total. The cart weighs 635 lbs. in this configuration.

We run a custom golf cart motor that's direct drive.

And here's some shots of the finished product the way we ran it in 2013...

http://farm6.staticflickr.com/5456/9082286802_216bb36c27.jpg (http://www.flickr.com/photos/[email protected]/9082286802/)

We run the 1/8th only. Best passes were 8.31 @ 79 and 8.47 @ 80. We're going to a 348 volt/2000amp controller for 2014 and upping the voltage to 240 so we'll basically have twice the power that we had in 2013. The cart will weigh 710 lbs in this configuration. I have the additional batteries mounted and the controller ordered so should be able to do some driveway test hits in the next couple of weeks.

Here's the new battery configuration. Now packing 21 - PC680-s including the 1 for the controller.

Here's a couple of vids.

We bracket race and lots of times we are against stock carts so here you can see what it's like to wait for 20+ seconds for the green. :rolleyes: This is from the OP Gas vs Electric Cart Shootout at Ozark Raceway Park.

And the GoPro from our first ever 80 mph pass at Tulsa Raceway Park. :D

https://www.youtube.com/watch?feature=player_detailpage&v=_E65abcWMM0

It's not the world's fastest or anything and I don't own any Guiness records. Some people say it's not a golf cart at all but we're having a ball racing it whatever it is. My wife of 29 years comes with me to every race. We are a team in life and racing and we're having a blast.

Thanks guys. It's been a really fun project and quite challenging. I've never messed with this kind if voltage before. Trust me, it will get your attention if you aren't careful. We hope to go 7's and 90's in 2014 but we will have to wait and see. This much added power is either going to go fast, tear up all our stuff or scare the crap out of me or perhaps some combination of the three. Lol.

Thanks!! I've watched the YB cart race videos. I assmue that all the fast cars are gas? Would be kinda cool to put together a really fast electric one for that race. Wonder what I could get mine to run if I geared it for the 330?? Hmmm...

Got the new controller and computer installed. The only catch is.... it won't run. :rolleyes:

I've been around and around everything over and over again. The computer and the controller lose communication the instant that it sees throttle input. Looks like I apparently got a bad brand new $5k controller. Sending it back to the manufacturer now. That's racin' I guess.

Anyway, here's some pics of the new parts and done wiring. Was hoping to be doing dry hops in the driveway for Christmas but I guess not. :(

Yeah, wer're eat up with it. Perhaps I've just had the crap shocked out of me one toooo many times.

There are gas carts that race also but the electric carts are faster by a pretty good margin. Most of the gas guys run high 8's or low 9's. Several electric carts in the mid 8's and there are some that have even run 6's but those guys don't seem to come out and race. They just post numbers and go back home and won't come to the races where the rest of us are. I'm in it because I love to race and the challenge of the electrics really appealed to me. It's been fun but 240 volts will get your attention if your finger...or whatever...is in the wrong place. :rolleyes:

Continuing the updates for 2014 by adding a battery management system. Some of the batteries fill up faster than others which causes them to go well above the 14.8v target which will eventually damage them and causes an imbalance in the pack because the others never get fully charged. Manzanita makes some battery regulators to solve this issue but the are $75 each and now that I have 20 batteries...well...I wasn't going to go there. I found 12 of them used that I was able to buy for $350 so that started me on the BMS quest.

I wired all 20 batteries with Packard 56 connectors so I could plug and unplug the BMS easily and so that I could plug the BMS onto the batteries that were overcharging since I only have 12 regulators.

I mounted them on a piece of 1/4" Lexan cut to fit on top of the center battery pack so they will be out of the way but still handy when I'm charging. I also wired my multimeter with a Packard connection so I can just plug it into each battery to check the individual voltage.

Here's what the regulators look like...

And here they are mounted, wired and ready to go...

http://farm6.staticflickr.com/5516/11939221616_6b77e2edb8_b.jpg (http://www.flickr.com/photos/[email protected]/11939221616/)

And here is how it works on the cart. I've wired the BMS connections to 10 batteries on each side so I can pick and choose which of the 6 regulators need to be plugged into each battery. I did make up some jumpers just in case there were more than 6 on one end that needed a reg.

http://farm4.staticflickr.com/3834/11939222236_c82a6f2bdf_b.jpg (http://www.flickr.com/photos/[email protected]/11939222236/)

This should extend the life of the batteries and give me some more consistent power with all of the batteries balanced. I've got 12 PC cooling fans on order and I'll be adding another piece of 1/4" Lexan on top of the regs with that will hold the 12 fans. More wiring. Yippee.

Thanks for looking!! More to come!!

Pretty easy and fairly cheap to go 12.90 with an electric junior. I'd suggest joining NEDRA. Lots of folks there with juniors. Here's the link to their junior page.

Would a hybrid battery pack from an automobile application work in this kind of setup? They're 330V deal, and would probably end up being lighter than all those batteries if you took them apart.

We tow the cart to the staging lanes and I drive it back to the pits. I can recharge in 15-20 minutes. All depends on what batteries and chargers you use really. We use 5 golf cart chargers in series.

The packs like from the Pirus for example are not a very DIY freindly battery chemistry. They are NiMh. Hard to charge correctly. The Prius packs have plenty voltage but not enouh amps to supply what we need for racing. Itt hink they can only deliver about 100 amps for 10 seconds. Voltage = rpm. Amps = torque. We're shooting for close to 2000 amps from our system this season. The tried and true AGM's are the best bang for the buck for our application. The big time guys in electric racing all run lithium packs but way out of my league financially. $40k battery packs are prolly not in our future.

Seriously, there is just about zero maintenence to the electric powered juniors at the track as long as you don't break anything. I doubt anything would ever break if you are shooting for 12.90. Would be a super simple setup for a junior. Don't see why it wouldn 't work out for you and your kids to all race.

Once we got the right setup I literally changed one motor all season which takes 10 minutes and did nothing at the track but check tire pressure and recharge from there.

There are only two rules for the yb nats golf cart race. Must be a golf cart and must wear a helmet. And monty's definition of a golf cart is real loose.

Yours is as much a golf cart as the one that's been winning is. I don't think there's a single golf cart part on that thing.

We do run the golf cart rear end and motor at least. :D I'll go ahead and vote for it being attached to a nice 4130 chassis though. The guys doing that with no cage or anything are nuts. :rolleyes:

Yep. My atv motor deal is pretty slow but it's still pretty sketchy at times. Would like to build a tube chassis cart but wallet is thin enough as it is.

Cool deal with the YB vid!! Dam that's only 330? Wonder what Monty's would do in the 1/4?? That's just crazy! And 12K for heads to run maybe 7's in the 1/4, hell yeah!! 12K to run 14's in a go cart, I'd pass but that's just me!

Terryh....You say there are several carts that you run GC national events and the NEDRA stuff.

So where do you go to find chassis and safety rules to build one? 12K is alot of jack and I know some track I've run at are pretty strict with following rules. I've seen people bring some wild shit to the track only to be parked and looked at.
Is there a web site somewhere with rule info, maybe some pics of the group, event info?

We actually run 1/8th so the times I've posted are for the 1/8th. We run the direct drive rear ends so there is basically 1 gear so the carts are much more suited for the 1/8th.

There was an association (NGKRA) National Golf Kart Racing Assoc. but they have folded. They established the rules that we still adhere to but we basically run outlaw where pretty much anything goes. There are about a dozen or so of us that are pretty serious about the deal and we have a gentleman's agreement to basically keep the rules from NGKRA. One fo the founders of that association was building chassis for their Super Pro class and I bought my chassis from him.

Here is a link to a golf cart forum where there are a bunch of pics and such from the events....

So your keeping the rules a secret because of a association that has folded....hum.
And the pretty much "anything goes" could mean that someone puts the funds into building something, shows up to race and then finds their cart don't fit within the "hidden" rules.????

Checked out the site, I don't see very much interest, looks like a few of the same people posting comments and pics of the same carts, yours and a couple others, but not a dozen or so like you stated. Am I missing something?

Seen on there that a guy crashed and got a ride to the hospital? What happened, axle break, front wheel fall off?? Oh, bet that info falls under that "gentleman's agreement" too???

As I stated, we basically run outlaw so the only real rule in place at this time is that you have to have a helmet. You own a helmet right? Ok, good. You're legal.

There are 25 or so serious race carts on the planet that I know of. Every cart doesn't race at every race and every racer doesn't post on the forums. Some of the guys are not racing for assorted reasons. Some are butt hurt and some are just butts. Believe it or not, people being total jerks to each other on the forums, name calling, and going as far as trying to intentionally damage other people's businesses etc... have hurt the sport. :smt073 12 or so of us are still racing. Some gas and some electric. They are scattered from Cali to Florida to the Carolina to Indiana so every cart is not at every race. Obviously, it's a huge sport. :rolleyes: Those of us that race are having fun and trying to keep our piss ant sport alive. I really don't care about much past that.

Here are the rules that were in play when the NGKRA was around. These are the rules that most of the carts were built to fit. Most of us continue to honor these rules but carts have raced that are built outside of these. Again, you have a helmet right? :D

As far as the guy who crashed in Georgia, he's a good friend but not a very smart one sometimes. :D He built a cart with a double butt ton of power with no cage, stock wheelbase, stock suspension, stock steering, stock brakes etc.... Sort of like a stock Smart Car with a top fuel motor. He lost it on the first pass and flipped the cart. He's ok but had some serious road rash and was more than fortunate it wasn't much, much worse.

Wow! Don't sound like the kind of people anyone would want to be involved with and no good if your trying to get a group into this type racing!
One thing to get harassed about on track shit, which is usually in good fun, but to try and intentionally damage other people's businesses! Over what? Someone ripping someone off? Sleeping around with the competitors wife? That's going a bit far for being just a sore loser! LOL, oh the drama, and there's not even a class for carts!!


And you might want to add some more rules to that "Just need a Helmet" rule. As your friend has proven that it would be a good idea to add more protection.

Racers bad mouth other racers. It's really not anything more than goes on in some of the threads here or anywhere else that people are bieng people. Racers talk trash and go over the line with it on a pretty regular basis in person and even more so on the internet.

I've lobbied for more rules in the cart races since I started racing them but I'm not the rules maker. That's one reason that I'm a member of the NEDRA now. They have established rules and they are an ASO for the NHRA. I ran exibition passes for them last year and I'm running more stuff with them this year. They are working on classification of the carts now. If that doesn't work out then I'll be pursuing a different chassis to put our combination in so we can be a little more mainstream as a regular dragster. We'll see how 2014 goes and take it from there. One way or the other, I'm going racing. :D

Well, it's alive again after having to send the brand new $5k controller back to the manufacturer because it was DOA on arrival. Seems the dude with the soldering gun missed a connection when it was built. It apparently was connected enough to pass the tests at the factory but the UPS ride disconnected it. Anyway, I got it back today and I got it on the cart this afternoon. With the amps set to 1300 and volts to the motor at 150, I could hear the slicks barking on the launch with a big woop, woop, woop. Amazing what you can hear when the dragster doesn't make any noise.

The cart has been lazy on the launch with the best 60' of 1.960 It was pretty cool to feel it launch that strong today. Upon further inspection the cart actually ripped the sealer off my driveway. :D I have lots of room left to crank it up. We'll be trying to lay down a stout number and claim the NEDRA DR/B 1/8th mile record as soon as we can. That record is vacant at this time so any legal pass will be a record but I'm pretty determined to claim that record with a seriously good pass. We shall see. When do those tracks open again? :D

Have you seen an electric cart that fast? I haven't. He says there is around 12 or so of them that race? Id say that is pretty unique and different. And BTW if you had read the thread, i asked a lot of questions about the setup for Jr and I am actually leaning that way when my kids are old enough, about 3 more years.

Not in person but I've seen a video of one, holds the world record going 103 mph in the 1/8th and it's actually looks like a golf cart.

"12 or so of them that race".. like terry said, half of them are butt hurt. :-Shower So how many really do show up at one of their so called races?

I've read the tread. I think it's great you want to get your kids involved at a young age and jr dragster would be a excellent way to start them out. Gas or electric. They have already established a set of safety rules and classes for different age groups. Jr's? Google "ten-year old Layton Krauss". Besides would you ask a quick lube mechanic with little racing experience how to setup the chassis on your racecar? :lol:!

On a brighter note......


I'm really enjoying my new job and the time it's allowing me to do something besides work. Took advantage of that today with the swap of the rear end from the 8:1 rear to my 6:1 rear. I did that mostly because I got a new motor that I'm pretty excited about. We were obviously in dire need of more torque last year. I think the additional power coupled with this new motor should solve that issue.

Here's the new vs the old.

8 brush pack in the new motor.

Got it all back in the cart and ready to rock.

The new motor has a speed sensor that will actually go to the Zilla for rev limit control, diagnostics, and tuning. The Zilla has tach output so I found this cool little shift light that is also a 13,000 rpm tach on Ebay. I think it should work great. It has recall so I can check the max rpm once I'm back in the pits if I don't see it during the run. I fabbed a bracket and mounted it on the steering shaft support.

Spent a snowy afternoon in the shop finishing up the motor/gear/tach install. Got the tach bracket trimmed up and painted along with wiring a switch for it. Also got the wire ran to the controller for the tach signal. Filled the rear end with lube and had a bolt check. I think that once the shielded cable comes for the connection between the motor speed sensor and the controller that I'll be ready to race.

You don't like me. You don't like my cart. You don't think that chassis carts are carts at all. You don't like the people that race carts and you don't want anyone to build one. There, we should be good now.

I had some shop time last night and the cooling fans for the battery management system finally came so I got them installled. Wish I had 20 regulators but I couldn't pass up the deal on these 12 used ones and they will work but will require a bit more attention from me but that's ok. I bought 12 standard 80mm PC cooling fans and they are actually powered by the voltage being bleed off the overcharging batteries so they perform a dual purpose both cooling the heat sinks on the regulators and helping the regulators bleed the extra voltage. I'm pretty happy with how the BMS turned out and it should greatly help keeping the pack balanced at the track.

The BMS assembly fits perfectly right in front of the Zilla. Super handy spot so I can plug into which ever batteries are overcharging and this spot should provide good air flow for the cooling fans.

Finally to the point of doing some test hits in the driveway. Cart was super lazy on the hit last year. More power is a good thing. I still have it turned way down but it's spinning the tires on the launch now.

Hey Ryan! What's up? It sucked. Ran 1.6 60 ft but only 8.75 @ 70. Haven't found the balance yet. I've made some changes since the test but haven't been able to get back to the track since. I've calmed down the power on the launch. Hope that will get it out of the hole without shaking the tires so bad and leave me more power on top end. This new motor has a mountain of torque if I can figure out the right setip I think it will run mid 7's. Hope to get back to the track in a couple of weeks.

Glad to hear it, cant wait to see that first 7.99 for you! That's a great goal for now. Just a thought and whats been working for lots of us lately, air up the slicks not down and I think you will find your sweet spot. Id say your to low letting them wad to much and when you drive over that wad you have less surface area and it causes shake. I fought it bad my first trip out. Im several lbs up from where Id think Id ever run a tire this big and its just getting better and better. I run a Hoosier 32x17x15 D06. You want some wrinkle w/o no wad on the contact patch, find that balance for your weight and power. Whirrlin' the tire out of the hole sometimes is much faster than a dead hook so be mindful of that also. Good luck Terry!

Mines doing great and having a blast, I just have to hone my skills at the tree again for being out of it for a few seasons. All's good

Thanks. I'm looking forward to that first 7.99 as well!! I was running 7.5 psi when it was winding the slicks up so much and shaking. I've actually took the video apart frame by frame and it actually pulled the front end up twice in the first 20'. The 2 big barks after the initial hit were right after the slicks look like they are almost off the ground from running over the hump from them being so wadded up. I increased to 10 psi on the next pass and it spun but actually ran almost 1/10th better 60' and 2/10ths quicker et. I've dialed some power out of the launch to see if that will help. The issue for us is a finite amount of power and a finite time that the batteries can produce that power so being efficient at the start leaves more for the top. The setup is a continuing experiment. I'm confident that I have the right pieces now to run some good numbers just clueless how to best use them. :rolleyes:

Good to hear from you and glad to hear you are having a good time running yours!!

Well, the winter of work has still not paid off with et or mph but 60ft times are not an issue. We've certainly got plenty of steam on the launch. If anyone out there would like to sponsor a nice Lipo battery pack with charger and BMS, let me know. I think my old AGM pack is getting pretty tired. Tons of power on the launch but can get it to run on the top end. Here's a launch photo form last night a Tulsa Raceway Park

We've taken the big plunge. STR has gone LiPo. 3P60S, 250v, 90C, 300 hp LiPo pack from Lonestar EV Performance. Pack is 11" x 13" x 8" and weighs 70 lbs. Go big or go home I suppose. Install is underway. If everything goes well we will be testing at Tulsa Raceway Park next weekend. The cart will go from 738 lbs. to 493 lbs. Likely we will run out of driver before we run out of power now.

Pretty straight forward install. The right side pod fit the pack perfectly. Couple pieces of 1"x1" aluminum angle to keep it from moving forward and back, some 1"x.25" aluminum bar for hold downs, and some 5/16" stainless all thread to mount the bar stock it was in there and secure. Easy wiring job also. Just a new + and - cable to make and a little longer wire for the volt meter.

Few test hits in the driveway sneaking up from 25% power to 40%. Making sure that the smoke doesn't escape from anything. Cables, modules, and motor all cool and looking good. Butt dyno says we are good to go. Spins the tires hard on 40% and pulls like crazy after that. Pack recharges in 10 minutes. The most amazing thing is when you push the cart it's like it weighs half as much. Can't wait for Friday to get here so we can see for real on the track.

Many props to Shannon Beeler of BDRC race cars for helping me out on the wheelie bars. He came very highly recommended and I see why. I took the cart to his shop outside Springfield this morning and a few hours later, I have a set of awesome bars on the cart and it's back home.

https://farm4.staticflickr.com/3905/14566570447_88896c82a1_c.jpg (https://flic.kr/p/occtUk)

All 1" 4130 with 1/2" heims. Shannon had the idea of attaching the upper tubes in the ends of the existing 1 1/2" rails. It worked perfectly.

https://farm3.staticflickr.com/2916/14752704612_ee2a8c9e2b_c.jpg (https://flic.kr/p/otDt75)

The lower tube is mounted to an existing 3/4" tube in the chassis that he reinforced with more 3/4. Lower tube has a left and right heim so it's adjustable. He even knurled part of the lower tube to make it easier to adjust. Bars are 64" from axle centerline to the centerline of the wheelie wheel.

It's been quite a thrash but it's starting to look like something again. Couldn't resist doing a matching paint scheme with the pit cart.

Got our junk back together. Not a bad outing last weekend. Couple of driver confidence/driver's wife confidence passes and then we turned it up. Dew was falling big time at Ozark Raceway Park on Saturday night but we wtill managed 5 passes in the 6's and the 90's. Best of 6.71 @ 96.22. 1.4 60's and 4.2 330's with the cart sideways at the hit and spinning the tires. Felt good to be back at the track though.

Few pics from last weekend.....

Made a few changes to the dragster over the past few days to save some weight and hopefully improve it overall. I moved the emergency kill switch to the rear compartment which saved 8 feet of battery cable and made it much more accessible for track workers in the event they ever need it...again. :rolleyes:

I also removed the PC680 AGM battery that I was using to power the 12v systems and replaced it with a much smaller and lighter alarm backup battery. The new battery is 6Ah and weighs 4lbs.

The major project was to modify the center battery compartment in the chassis so I could move the LiPo pack to it. I removed the old mounting points and fabbed a new battery tray that I welded to the existing structure.

The pack looks right at home in there. This saved 4.5 feet of battery cable which pretty much offset the weight of the battery tray so it's a win all the way around. I had the chassis centered on a jack and moved the pack until it was perfectly balanced from right to left which slightly offset the tray to the right. Having the weight of the pack centered and lower in the chassis has to be a good thing.

Here it is all wired up and ready to rock.

Motor is in Cali getting a couple of tweaks. Should be back next week. Hopefully next Saturday we'll be back at it trying to find that 100mph 1/8th mile.

Last night was an exercise in how close can you get. Dragster ran great but came up agonizingly short of the 100 mph pass and had a controller issue right before the last pass that would have probably put us over the 100 mph mark. :rolleyes:

Hard to be disappointed with these numbers though...

7.18 @ 89.78
6.97 @ 92.40
6.71 @ 96.44
6.58 @ 99.12
6.54 @ 99.91

The last 2 passes are the fastest and quickest ever for us and the quickest and fastest for the B voltage class. We'll be submitting the form and the slips to NEDRA to certify the 6.54 @ 99.91 pass as a new world record.

The cart finally made the 100+ mph 1/8th mile pass today just not with me driving. Good friend and ORP track worker Chris Askew was at the wheel. Here's the GoPro from the 6.83 @ 101.06 mph pass and the time slip. Was so cool to have about 15 cub scouts right by me on the side of the starting line watching this unfold. The little guys had been taking turns in ORP's in house junior dragster. It was a good day. The actual goal is still out there though. Next year it's 100+ with the fat guy driving. :p

Miss the updates, hope everything is going well.

Thanks for asking. We figured out a couple of things battery wise over the winter that gave us some more power. We've only been once this year and it didn't go very well. We ran 6.62 @ 98 but hurt both our motors. Very thankful that Helwig Carbon has come on board as a sponsor and we have 2 new motors being built right now using some custom brushes that they sent us. That should solve our commutation issues. It definitely has more in it if we can keep the brushes in it.

We will be running a cart race that's part of the M/T Shootout at Ozark Raceway Park on July 10-11. Few other drag carts coming so should be a good time. There is a cart show and shine as well. We have door prizes, trophies, 50/50 pot etc... If anyone is in the area or racing at the Shootout, the race is open to anyone with a cart.

In typical drag racing fashion a solved problem leads to a different problem. No brush flashover last weekend but it arced out from the spring to the negative pole instead. Going to drill the pole mounting points farther away from the brushes, insulate the heck out of them and go again. The experiment continues. :rolleyes:

Thanks for asking! We got our newly designed motors in just in time for me to have to have surgery last fall and miss the remainder of the season. I'm just doing normal winter maintenance right now, changing our some tired battery modules and running in the new motor stuff. These modules are all getting tired. They were used when I got them and have over 300 passes on them now. Hopefully back together and back to testing in a month or so.

The guys at Advanced Lift Motors did some pretty serious outside the box thinking on the new motors. They've eliminated or moved all the internal connections. I realize that this doesn't look that much different but it is a major change. I'm feeling good about this solving the arc out issues. 'Course we are still jamming 25 lbs. of crap in a 5 lb. can and electrons go where they want to go not necessarily where I want them to go. :rolleyes:

The carnage continued last weekend at TRP. Melted down a few batteries. That's racing. New pack on order. Thanks to the guys at Lonestar Performance EV for helping me with the new pack.

On a brighter note, the track photographer, Red Williams got some pretty cool shots of the dragster.

Today was a gorgeous day at Ozark Raceway Park. Didn't take long to figure out that the new battery pack has a ton more power than we've ever had. I had it turned WAY down to start....or so I thought. 1500 amps, 140 volts. We normally ran 2000 amps and 190 volts. 7.02 @ 98.27 right off the trailer. Really soft launch but it was hauling on the big end. I got too greedy on pass #2 Amps to 1800, volts to 150. It was on an incredible pass but flashed over the brushes about 400 feet. I coasted through the 1/8th mile at 6.76 @ 83.94. 4 brushes damaged. No damage to the comm.

I changed the brushes and had Cheryl hold the throttle while I applied pressure with a dowel to get the new brushes run in. I turned it back down to 1500 amps and 140 volts where I began. Ran 6.92 @ 99.14. Added a bit more for the next pass. 1600 amps and kept the voltage at 140. That resulted in a 6.75 @ 99.84. Almost painful. That was the 5th pass we've made over 99 without getting to 100.

1650 amps and 145 volts for pass number 5. We headed to the lanes when they were calling 5 minutes before they were closing. Once again about 400 feet I felt it flashover but it just popped and kept on pulling so I stayed in it. It popped again right in the lights. I can't hear the announcer but the safety guy at the big end came over and stuck out his hand to shake mine. 6.67 @ 101.81!! Finally after 3 years of trying and lots of dollars and a mountain of work.

For the record...
