ARC-2: results
Anyone have experience with this unit???
guys over at SH.org are gonna test it.
http://www.fastbygast.com/ARC-2page.asp
"Built in Two Step and Retard
189MJ Spark!
Pick up 9-12HP just bolting on!""
Dynatek Announces the ARC-2: Asynchronous Restriking CDI
Dynatek has introduced the ARC-2 for 4 cylinder Motorcycle applications. This CDI ignition is capable of producing over 50,000 Volts at the spark plug, and has the highest spark energy of any CDI on the market. It is designed to optimize the ignition of modified vehicles, providing the strong spark needed to develop peak power for turbocharged, nitrous oxide and high compression applications. Intelligent Spark Profiling allows for less delay between successive sparks. It also features a built in launch limiter for drag style launches as well as a built in retard mode. The lightweight and compact ignition will be offered in plug in kits for select motorcycle models that will make installation a breeze, with no need to cut into the stock harness.
For other models, a universal install kit is available.
Technical specifications:
Operating Voltage: 8-20 Volts
Operating Current: 7.0A @ 10,000 RPM
Maximum Operational RPM: 18,000 + RPM
Ignition Inputs: 2 rising or falling edge
Ignition Outputs: 2 independent channels
Coil Primary Energy Max: 189+ mJ
Coil Primary Voltage Max: 500+ V
Restrike Window: 25 crankshaft degrees
Launch limiter input: Single wire, ground to activate launch limit.
Retard input: Single wire, ground to activate timing retard
Tach output: 12V square wave, 50% duty cycle
Dimensions: 4" x 4.6" x 1.4"
Weight: < 1.25 lb.

Actually,4x4.5 doesn't seem too big anyway.What is volts of the 12's spark stock? Can this box alter the timing through out the rev range or is it just for launch and on boost or spray?

Sorry Karl, I have been busy with work and the family. Yes it is a nice unit plug and play, but the wiring kit is a must!!! lol, it's an extra bill as well. Only limited use on my bike. If you like Karl, I can pull it off my bike and ship it to you for testing on your bike.

The adjustability is nice, but 9-12 hp is serious marketing optimism.

for $400 i would be thrilled with a 3-4hp improvement
Gary,
thanks for the offer 
I'm calling Schnitz right now.

I think the 15:1 compression ratio's, and boosted, or Nitrous applications would see the biggest benefit from the multistrike and increased voltage
Sounds like a nice piece though.

I won't be surprised. Multi strike systems have proven to be the shit. This is probably a very good development for us.

I will do a pure apples to apples dyno comparison 1st week in June, see if this lil baby can help get us down the Mile a titsch faster
Also, the charging system was apparently NFG, don't know for how long.
This morning I pulled the fuse block/magnetic switch from behind the battery and found one side of the 30A fuse distorted from heat...

I'm looking forward to your report Karl, thanks.
I wonder why the manufacturers don't consider this sort of ignition, if it's only $250, and will give them an edge in the HP wars?

does a guru mind explaining the multi strike system? my guess is it fires multiple times during the time a normal system just fires once? so every now and then under extreme conditions, the normal system doesnt ignite the mix every time where as the multi has more "chances"?

No guru here, but yes that is correct Scott.
MSD has been using this technology in their high capacity discharge boxes for years on cars.
It has not shown discernable HP incresases in moderate or low compresion NA engines, but has been good for the high compression and especially forced induction engine applications.
I wonder if this has a programable curve based on analoge inputs, such as boost referenced timing curves... that would be cool.
I can do that with the MSD 6sb box, but I do not think its multistrike, or multidischarge as MSD calls thier versions.
Another way to dramatically increase your secondary voltage is by increasing the primary voltage.
Even increasing primary voltage by 2-3 volts creates a much hotter spark.
MSD made a voltage regulator for cars performing that function over 20 yrs ago as well.
It was great for increasing headlight and stereo output too!

I remember MSD version vividly, and if I am correct it was multistrike over 30 crank degree's,
Back in 1989 I had '70 Cuda.
When I was in highschool I was geting parts for the car, a friend of mine and I walked into the local performance auto store where they had a display on the floor to show the increased arc and plug gap ability, as well as multi spark ability.
It was quite impressive.
He had not seen it before and I managed to get hom to hold on to the electrode end.... he jumped about 3 feet off the floor when he got hit with it!
LMFAO
I wanted one of them things BAAAD, but couldn't afford it on my part time paltry paychecks.

I am outa town till sun, then 1st week in Jun will finish another set of tests.
Mr Multistrike will be tested 2nd week end in Jun.

thats a pretty slick device.
one thing i see a trend in is marketing high voltage secondary outputs and in a way, i almost don't understand why.
after all, you can only have "so much" spark before you actually reach a point of blowing fuel away and misfiring. ya, compression and an assload of other factors exist in makin that a truth, but has anyone else heard of that? i know for a fact i've read and retained than info. to little power-no good.. spark won't happen under pressure. too much- it blows fuel away and won't light it.
thoughts? don't mean to threadjack on that.. sorry..

Here's my take-If you make it, they will buy it, especially when good marketing is thrown at it, whether it works or not. I'm skeptical myself of pretty much most aftermarket claims.
