CDI Ignition Systems

[12at]

Hey have been looking into some CDI Ignition systems for my 12at as im wanting to run some decent boost on pump along with a australia based water injection setup that has been used in many 700rwhp+ 13bs.

Does anyone on here run any CDI set ups  on their engines?

interested to hear from some people and what setup they running..

Cheers

M&W pro 16 on mine more like a welding spark than the usual weak spark be carefull with any CDI though it hurts if you get a belt also look at upgrading the coils.

Where did you get your m&w setup from? I am thinking about getting one but can\'t find a good price in the uk.

[12at]

The pro12 is what a mate back in aus suggested and is a 2 channel. He said to run 2 boxes and get some cdi coils..

I have heard of people using the pro 14 and using the Bosch hec715 coil

Any more info on sellers in the uk if not might be a aus purchase again

[kev-yorks]

The bosch 715 is the same coil thats used by haltech, motech and microtech just rebadged Thor racing are the UK agents but it ain\'t a cheap option tbh.

[12at]

Yeh Thor racing has typical bull.... UK pricing.. Change the $ for a £ symbol

There is no way a pro12 4 channel is close to $2000!!

Will speak

i assume your talking about riceracing w/i, if so how much boost and what size turbo, that will give us an idea of what sort of system you will need, if rice racing then pre-turbo w/i

[12at]

Yes that is correct i have a rice pre W/I set up.

looking at around 20psi on my half bridge which has a T67 on it.

Also looking at something that i can use ones back home on my 1000 with a 13bt and a GT42rs.

Another one if been told isnt to bad to run on the leading plug only is the dynatek CDI.. Anyone heard anything about that?

[12at]

heres a link to the dynatek stuff

[turbotoaster]

it depends how much spark you need i suppose.

Looking at it there ware 2 ways this can be done with most manufactors.

either plug a unit in, kind of like twinpower or the ARC-2 which is a full CDI unit.

Or use a kit that just connects between your trigger and coils like there dyna 4000 or okada projects plasma booster.

since we are only planning on strengthening the leading plugs it doesnt need to be to complicated, the problem arises is the lack of testing thats been done on rotarys,

We know that a twinpower can cope with a t70 turbo with 23psi of boost and 575cc of water on pump fuel....but then we dont know how much further you can push it.


Also comes down to budget partly, ill give dynatek a call in a bit and see if i can get someone from tech to give me some info

[12at]

Ive just got off the phone to dynatek and the guy knew nothing.. he said basically call Dynatek in the states here in the UK they basically deal with bike stuff.

[turbotoaster]

haha ditto, spoke to him aswell and he mentioned he spoke to yourself, i was gonna email them in the states now, have you already done that yet?

[turbotoaster]

he did mention though that the arc-2 would be much easier to fit than the drag system and they will both put out the same level of spark so assuming we get good info from USA this looks promising.
 
He did mention he thinks it would work fine though from his basic knowledge on car ign systems

[12at]

No haven\'t had a chance to email them or call

Yeh he did say it was capable of running with standard could but again he was shaddy and kept on asking some guy in the back ground. He said he has never opened the catalogue.

Speaking with a guy back home he has run the arc2 on leading and the microtech x4 on the trailing and has had good results.

Let me know what the USA say

[turbotoaster]

well i basically emailed them explaining its for a rotary engine, havent gone into requirements in terms of power yet as i wanted to make sure i was speaking to someone who knew what i was on about.

a simple proven setup is a MSD 6AL system with 2 blaster coils, theres wiring diagrams ready and you know it will defo work, its $340 for the lot so thats at the back of my mind currently. they are only 135mj though

if i explain to them i need a strong spark with 100lbs of air, 6000cc of fuel and 800cc of water im hopeing there will be a way for them to calculate whether there system is up to it, they have said 189mj which is alot, much more that M&W which have been run on some big power cars(115mj)

i think the standard setup is about 60mj, so thats over 3times the power
