HERES MY LITTLE "RATS NEST"

THATS ALL OF EM,
LMK WHAT YOU GUYS THINK

Wow, that's gotta be the most full on ignition system I've seen.

One suggestion though, you can move the trailing plug leads and coil lead over to the leading positions on the dizzy cap. That way there's only one air gap for the spark to jump.

V8kilr

i dont understand,but am very intreged,
please explain

REVHED

Just take your dizzy cap off and look inside.

You'll see that the spark from the leading coil goes straight through the centre contact into the rotor whereas the trailing spark has to jump over from the outer electrode.

Basically, the leading only has one air gap to jump instead of two which means a hotter spark.

Since you have direct fire on the leading now you can swap the trailing leads over to the leading positions on the dizzy cap to take advantage of this.

V8kilr

i think i'll just leave it as is,

i used to want to increase my trailing spark power as i increase my leading spark power,
bu after thinking about it,
and doing some reasearch theres really nothing to be gained after you get your leading running hot enough,

in fact i think if anything it would begin to hurt you instead of helping,

besides if i just swapped the wires over would the trailing plugs spark when the leading are supposed to?

REVHED

LOL, just swap em over! It's take about all of two seconds to do it. Besides why wouldn't you want a hotter trailing spark?

This will not change the timing. The timing is controled by the magnetic pickups inside the distributor. The dizzy cap and rotor is just a path for the spark to go through.

BTW, the direct-fire instructions at Mazspeed and Jeff20B's write-up both say to do this. Plus your cap and rotor will last longer as well.

"i used to want to increase my trailing spark power as i increase my leading spark power,

Why would you mount a blaster coil on the trailing if you didn't care about trailing spark? IMO, You might as well use the leading contact on the dizzy to finish the job. Nice job by the way - how do you like the performance?

V8kilr

so they all match

im gonna swap em over and see what happens,


the performance????

got me,i havent got my msd wires yet from scamchargers so i wont know till then,

right now im afraid to get on it until i get the wires,

it could cause serious damage to my msd 6a if i dont wait.

ok I gotta question. ok, I want to run direct fire. I have an 80 distributer, and igniters, and 1 j-109 igniter. I want to know, if I should change to a later model dizzy, to run direct fire The 80 stuff is perfect, and working fine. I am just curious, cause I want to REAL soon. If I should have the other one, I will just sell this setup, and I have an AWESOME deal, with everything I need, and more, that I will buy( I am gonna buy it anyway, just I would buy it quicker) I just wanted to know, before I go off and sell this setup

THANX LATERZ, Andrew

crafoo

Nice clean setup.

riffraff

inquiring minds want to know.. i am planing on going direct fire with my tax return (hopefully, assuming i get one). and i have an 80 dizzy in my 79, so it is not the crappy points style, but it does not have the internal igniters.

V8kilr

how do you guys have 1980 dizzy's with internal ignitors?

anyway as long as its not points it will be fine,

i personally would rather use an older style dizzy with external ignitors,


as long as its as reliable of a dizzy

you have to tap into one of the ignitors,
i feel it is the "weakest" point on my whole system,
and fear maintanance on it in about a year or two,

for my setup you will need these esentials

1 msd box "a 6a is more then enough"
"dont bother with a 6al unless you plan to run two of them"
3 coils "preferably 3 msd blaster 2 coils"
"coils must be mounted vertically,msd says so and i noticed from having mine mounted horizontially there was damage to the coils"
msd wires "must be helicore or you will damage your msd box"
mounting brackets for the coils "mine are conduit brackets 2" "
some wire "various sizes and lenghts"
a bracket to mount the coils
self tap screws
heatshrink tubing
solder and soldering iron
relocation of fusable links "if you want to mount the equipment like i did mine"
and of course time

this is just a mini check list so you guys dont jump into a prject with out having all the proper equipment

setup costs me around $245.00

riffraff

kilr, i donot have internal ignitors.. my dizzy is from an 80 (as i said above).. i was hoping not to have to swap it, to save time and money, and it sounds like i donot have to .. good

coulpe questions about that list: why are msd wires necessary? i just got a set of jacobs energy wires, will these do.
secondly, what type of damage did you see to your coils? i just got some msd blaster 2 coils, and do to lack of time i went ahead and mounted them horizontally (yah i know i should not have, but that is that).

V8kilr

well right when you go to msd webs site,or buy the 6a,or go to a place that sells the 6a,they will tell you that you need helicore wires,
well the only wires you can not use are solid core,

so you dont need msd wires,but you can not use solid core wires.

i dont know to much about jacobs coils,you would have to look into them to see how they should be mounted,

if your going all jacobs i suggest the FI box by jacobs,

it looks very nice,
matches very well with the rest of the stuff you have,
and is priced in the same range as the msd 6a

my coils started to get smoe black bubbly stuff on the underside of the coils from mounting them the wrong way,

good luck.

riffraff

i got the msd blaster 2 coils because i was planing on going to an msd direct fire setup... not really sure why i got the jacobs energy wires rather than anything else. but i did. i will have to look into those , i really donot want to have to go out and get a new set of wires already..

riffraff

okay. now i remember why i got the jacobs wires.. because they are cheap. they were half the price of magnecor wires... but i will email the company and find out if they are helicore or not.

V8kilr

i just tossed my jacobs wires,
but mine were not cheap at all,
it was the biggest size they made,
think they set me back about $100.00

they got messed up and rusted out from not putting that stuff on them that looks like vasaline.

what i was saying about the jacobs is you can still run direct fire with a jacobs setup,

you can run direct fire with just about any setup,

it all depends on what your goign for,

i already had the two blaster 2 coils and the 6a box so i just used msd,

plus i didnt want any more blue under my hood,
the airfilter is getting its color changed as well.

look up those new jacobs FC boxes
FC stands for fire control.

ok i looked up the box for you,
the thing is sweet looking,
i might just swap over to one of these if they are as good as they say they are.

here it is.


Jacobs FC 1000 $145.95
summit part number JAC-341000


here is a link to buy one

and here is a link to see what one looks like

this place says they got it for $136.00

i tried to find a comparision to the msd 6a but found nothing
