EV Drag Racing

[jonescg]

I've thought about this too. But wouldn't it load some cells more than others, putting them way out of balance with the rest? For a super-dooper drag vehicle, I can see how it would make things much simpler.

I have also thought about a contactor exactly like the boost setting he has on his kart, but engaging it when you are headed for a main straight, like upon exiting a turn or something. could be deadly though

[AussieJester]

It is Called ENOS. Electric Nitrous. And it hits just like a Nitrous bottle on an ICE bike.

To make it consistent and controllable, we used a timer and had a second contactor. That way you can still use the controller
to ride up to the line and back and have a bunch of power for the run.

I have a schematic if you want.


EV Ed

Would very much appreciate it yes Ed thanks in advance mate

@ChriS...i don't think i would be using it on a road racing bike buddy, need smooth power delivery not a BAM
when you exit the corner, think it would definately be deadly mate haha...BUT...by all means try it
just let me know which corner at Barbegello Raceway to sit and capture the aftermath on camera, for YouTube

Thanks champ...can email through to aussiejester@iinet.net.au if its not too much trouble?

Thanks again mate much appreciated

questions questions questions;

the electricmotorsport store so far seemed to have the best price for the mars motor, but the rest of the stuff there is over priced for sure, i just use them for an example of the parts i need...

its good to hear from you again Thud...

kim bless your heart, and bless your heart too EVEd - you know any help i can get is appreciated. you all know im a newbie to this EV stuff, and that wont stop me from continuing to race this bike... we all had to start somewhere...

thank you for the sprocket link thud - im a bit of a shopper and on a budget, so any good deals i can get really helps...

the speed controller has a more sinister plan - after this season of learning and testing, everything will be swapped over to a cx honda that will be welded to a forward trike and used as a daily transportation...

another thing, has anyone notice that the price of gas is increasing again - they are not going to stop. i own 90 acres in daisy oklahoma that has oil under it and i own the mineral rights to it - unfortunately it is under reserve and only the president of the united states can unlock it - once they do i intend to start a company that will manufacturer the plasma engine - an invention that has been around since the 1930's - i will then take all those gas hog vehicles that people will be glad to sell and convert them and resell them back to the public... thats my plan - if you dont believe me then do a search for the plasma engine combined with electric, it will be the future of the automotive age... crazy, we will see...

everything you all are doing here is being pioneers. we push the ev to the limits to go faster and further, that puts everyone here way ahead of the game - you are all the microsoft of the world... you should be very proud, i know im proud to even you all, you are all awesome people who think outside of the box and thats a rare thing anymore... think of all of the people who have no foresight and are depending on others to come up with an answer, you all are the folks they are waiting for...

[allen_okc]

.... i freakin LOVE the idea of the boost switch!!! Can see that being implemented in the drag bike project Timma2500 & myself have in the works definitely!

..should not be necessary assuming you chose the right controller ?
..but ....thinking "out of the box".. do you really need a controller on a brushed E drag bike ?
.. could you not just use progressive voltage switching..?? IE.. 10S, ..18S, ..24S or whatever suits.
could save some kilo's and $$$'s if it worked. ?

ive tried coming up with a solid state controller, even a resistor controller like a golf cart - its possible and would give the motor a direct feed of juice, i have several schematics for one, but it will require you to build your own pc clad...

but at the end im happy with the new kelly controller...

i know i would like the schematic EV Ed, can you send me a copy too...

Will do!

[allen_okc]

Thank You Sir...

[allen_okc]

i have good news and bad news;

the bad news is the new wheel is too big, the good news is, it leads me to a new project. instead of the forward trike, how about an electric chopper...

[allen_okc]

and now for the gooder news... the new motor is here... to which i owe a big Thank You to EV Ed... Thank You Sir for the new motor... ive started mounting it today, i fabed a motor mount last night... today i'll weld it to the frame... i think i found a wheel that will work off a XR 70 honda...

[allen_okc]

with that pic - i need to say to everyone, ive learned my lesson...

Unite motors - dont do it, you see how they end up

Mars Motor - bad arse, it rocks...

Time to start collecting lithium batteries...

[AussieJester]

Unite motors - dont do it, you see how they end up

Hate to say i told you so but, i told you so LoL...I learnt my lesson the hard way
but was slower learner i had to burn two of them up before admitting they were crap LoL

The bike will be a different beast with the Mars ans LiPO , i hope you have full set of racing leathers
the bike will be ALOT quicker now...

KiM

[allen_okc]

actually i do have a leather jacket for riding - but i would like to find a set of leathers that are black and green... seems hard to find...

i also found a wheel for it - i went to the yamaha dealer here in OKC, so i got a lot of work to do this week to get it all mounted.

i will have to spread the hard tail by 1 inch...

im still going with your advice Kim, lithium bats, i will have to buy one or two a week, but i will finally get them - i believe i have to get eight of the 22.4 packs, or do i need more?

spring racing is here and im running late already...

[JUICED]

a

i also found a wheel for it -

Great! got a photo?

[allen_okc]

hi EV Ed - i hope you got the message, A BIG THANK YOU again...

here is a couple of photos - im hoping a S rated street tire will fit, im not sure yet - 120/70-14...

[JUICED]

Very cool!

Hope it is strong enough for the RT motor....

Will this have a racing or standard tall tire?

Get the widest you can!

[Arlo1]

Get the widest you can!

Carefull make sure it has the largest foot print on the ground you can get.
Simply going to the widest tire possible will cause the sidewall to roll under and cause more of a curve in the center of the tire giving you less contact patch with the pavement!!!

[allen_okc]

this is the tire i was thinking of - it comes in a P,S,and H rating...

P rated - up to 93 mph
S rated - up to 112 mph
H rated - up to 130 mph

if this bike goes over a 100 mph, you'll hear me screaming my arse off in fear...

Tire performance is a tricky deal. With an ICE motor you want the tire to spin up to the speed where the torque curve gets beefy and then you want it to bite. With electric drive you have torque right away, so you'd just want to get a compound that bites hard right away?

I just remember being consevative with my 1985 "R" compound street tire at the strip because it was expensive and wore out quickly. I only spun it briefly on the way to the line and that was mainly to heat the plugs up on my two-stroker.

[vanilla ice]

For drag racing I'd worry more about getting something light weight than the speed rating. Its not going to be rolling very long.

The smaller a wheel is, the stronger it is all other things equal. Plus dirtbikes wheels tend to be strong. Looks strong anyway!

[liveforphysics]

Speed rating won't matter. It's about sustained speed tire cooling. Generally worse speed rating tires make better drag tires from less belts keeping it more supple.

Drag hondas often run the "do not exceed 55mph" spare tire doughnuts on the back for weight savings, and trap over 150mph on them.

If you're gearing for 100mph (meaning no starting torque), you don't need a wide tire, even a bicycle tire would work fine.

Also, the track will hook like no other surface. A good track is suck-your-shoes-off sticky on the starting line. I don't think wheelspin will be an issue with any scooter/motorcycle tire.

- i believe i have to get eight of the 22.4 packs, or do i need more?...

If you are still planning on the 48v class, and with your 400A limited controller,... you would really need 4 of the 6S Nanotech packs ...2P, 12S.
http://www.hobbyking.com/hobbyking/stor ... duct=14616
That would give you all the power you need, with more packs just adding weight.
Of course you could use another 4 to make up a 2nd pack as a back up !

[AussieJester]

Allen...have you considered a mini dragster rear wheel? this is what i want to use
on the drag bike i'll be building with Timma2500 later in the year.

If you are still planning on the 48v class,

The Mars RT is a big soggy turd on 48v...
