Ted Dillard replied to the thread ELECTRIC NOS BOOST.
" This is kind of a common question, and I went through some posts here to try to find a good thread about it, but came up empty. Anyway, the short answer is it's not really worth it. The general conclusion is it's better just to put the space, money and effort into a nice high-discharge pack. A few years ago that was what we fondly refer to as RC lipo, but now there are several chemistries that can deliver the power.

That said, nobody I remember hearing about has actually done it. (...as my son would say, "is that a challenge?" lol)

" The Sevcon should be the only thing connected to the contactor. The Sevcon controls it. You just need to give pack voltage to pin 1, KSI.

Wire per the manual.

Next, FS1 needs to be active prior to activating forward, and before giving throttle. Needs to be in that order. "

" Hi all,
I got my new sevcon, Thanks Travis!, but I need some help with the fault codes.(I tired searching the forum first)
I am converting from a Kelly so the setup is a little odd.
Basically I have my battery ground on a E stop(with high current auto disconnect) this connects everything including my dc/dc converter.
My key switch switches 12V from the DC to the contactor which then connects the 96V pack to the B+ on the sevcon and the logic circuit.

So first issue: do I need to have my contactor tied to the Sevcon to work? Can I just select 0 contactor inputs and have them all "not specified"
If I have it set to 1 I get a line contactor welded fault. Otherwise I don't get a fault. Alternately I tried to tie a dummy 12V relay to the contactor line and still would get the fault (contactor voltage set to 12V)

Second Fault: I get a sequence fault: I am assuming that I have an issue with my FS1 or FWD switch inputs. I have FS1 tied to the throttle switch and FWD tied low. REV is left floating. Am I missing an input required for the sequence?
I cannot seem to find much detailed info on what the sequence is.... Very "PC load letter" to me.

Thanks all and hopefully this helps someone else in the future too. "

" Hello everyone,
My name is john. I am from montreal, canada. I need a question answered concerning an idea i have concerning ev power.
Would it be feasable to power an electric motor solely with super capacitors to provide a say... 30kw boost to a motorcycle?? Power would be on or off, like a hit of nitrous. The power would not need to last more than 5-10 seconds. I know capacitors recharge relatively quickly so the motor can do regen on off throttle mode. This would also help stop the motorcycle.
Do you guys think this idea is sensible, or perhaps know if anyone has invented such a system?
Im no electrical wiz, i just think it would be a cool way to boost a conventional motorcycle.
My email is: jp1234554321@gmail.com
Feel free to contact me directly if you like. Thanks for taking the time to read this. -JOHN "

Im in st. Eustache. The build will be more focused once my front end is finished being built. I have respected the dimensions and parameters we have to adhere to with the quebec vehicle law. Once the project becomes a rolling chassis, then footpeg placement, seat height and handlebar placement will decide the rest. "

Here is a photo of what we are getting two of. They are the Gen2 Chevy Volt packs.
These are a larger version of what I have in the Cafe racer.

EVcycle created the thread The Juiced Drag bike progress post.
" Hello everyone !

This will be the thread that shows the progress as we build it. I will try to do weekly updates on how it goes.

For those of you that do not know us (Ed & Tammy - Juiced Drag Racing) We have been building and racing EVs for a while.

This bike it not going to rotate the earth. It will be fast enough to keep our need for speed happy, our retirement fund in check and
keep the other motorcycle bracket racers worried.

Smoky burnouts will be mandatory.

We are trying to build this in the 5 thousand USD range. I think with some help from a few friends and us doing 95% of the
build (I cannot paint that well ) we should make that happen.

The goodies:
A pro-built older, but perfect for this application, Kawasaki drag bike. The only Kawasaki parts (from a Ninja ZX-7R) are the steering,
front and rear wheels and the front brakes. It is Molly frame and very well built. It is set up for a 7" to 10" slick. We will be running
a 7" which is really 7.8" wide. It will meet the IHRA rules.

ME1507 PMAC Brushless Motor
Chevy Volt batteries set up for bulk and cell charging. It will be 116v or 130v. This voltage will be decided depending on the controller we get.
Right now we are leaning toward a Travis Programed SEVCON GEN4 SIZE 6 controller.

Paint - Chrysler Tangerine Pearl

The fun part will be getting all of this to fit. We have made measurements and a good plan, we will see how it goes.

Sorry, but I am old school, my cad file picture of the project is in my head.

Questions are always welcome. More later !
