How did you manage to drive those Blaster coils? Did you have a CDI unit, or did those coils have an ignitor built-in? Can you elaborate?
I am trying to have a good ignition system WITHOUT the need of a CDI boxe because no company out there makes a decent one with a competitive price.

also with the dis 4, does it use a 12v + to trigger the coil or does it ground out the coil to trigger it?</TD></TR></TABLE>
The DIS-4 uses ground to trigger the coils. All MSD DIS Series use this method. Everything else uses the opposite, a 12 volt + fires the coil.

It would be great if we can find out the cause of the failure other than being in the dark

I can certainly understand your frustration. I'm working on finding out the failures of this box. It seems to be a pretty popular box when converting to individual coils, and works well. I'll get back to you guys on that one.

ok cool, because with building race bikes, all of our systems trigger the stock coil using the ground which prefer, gives a more accurate signal imo. not to mention ive got a bitching custom made 6 led shift light that prefers to use the ground type trigger

My biggest problem with msd is there plug wires for B series engines. They like to pop off the spark plug way too often they should fix that they sell way more plugs.
I know i hated after every pass i could almost guarantee that at least one plug popped off the spark plug. </TD></TR></TABLE>
Are your wires a custom set that you assembled yourself?

No they arent, they are the ones made for his engine. All aftermarket plug wires do this even my old Magnecore 10mm wires, we just wire tie them, But
I use straight stock wires now anyways.....ooops I went to COP

they fall off on both ends dizzy and plug, but if u zip tie them to the dizzy they really dont give you any troulble on that end. on the plug side they just pop off the spark plug so u have to snap them back on.. every run it seems. </TD></TR></TABLE>
That's good to know, at least I am not the only one with superconductors popping off the dizzy. It's weird, you would think they stick on there pretty snug to prevent that or something.

i will soon be upgrading my ignition system too...msd digi 6, 8.5 wires, 2 step colder ngk, and cap and SS external coil blaster my car is miss firing so bad that i can't even do a clean pull on the dyno
Chuck Seitsinger ran an 8.37 @ 173 in the finals at the last event. He came back and said it must have hit a boost cut or something cause it was popping all through fourth. I looked at the datalog and everything looked great. When i went to pull the plugs out to check them, i noticed the #3 plug wire had popped off! lol It was kinda good news to us though, cause we know it has more in it!
On a side note, that car used to have a digital 7 ign on it and we had to change plugs all the time or it would misfire at high boost. Chuck finally gave in and got a motec cdi ignition. Never once had a problem again. About halfway through this year I noticed his plugs were starting to rust and i asked him how long he's been running them. He kinda got an odd look on his face and thought about it for a min. He said, they're the ones you put in a year ago when you did the ign., they've never given me a problem so i never changed them! lol That was almost a full year of racing on 1 set of plugs, running well over 45psi, sometimes upwards of 60psi!

These will help cure that problem when they come out:

Not 100% sure of their release date yet...

I heard somewhere (can't remember where), but there can be so much blowby pressure in the cylinders that it goes around the piston rings then actually around the spark plus seals and pops the spark plug wire off. We had this problem on a car in the shop so we took a tiny drill bit (1/16") and made a small hole in the black rubber cap covering the hole.
I took some wire cutters and cut out a little pizza shape in the boot on the motor so that wouldn't happen. Thing is, i did that over a year ago, still happened! lol The heat and vibration just starts to take a toll on things and loosen things up.

That's impossible. The blowby would not come back at the spark plugs since the spark plug is airtight.

I don't know how possible it is...but I remember reading about it from a pretty reliable source (one that wouldn't just say **** to say it). It was from a company I think? I really can't remember.
I could picture that with insane crankcase pressure and shitty seals from the valvecover to spark plug tube (whatever you want to call it). Back when my head was screwed up the crankcase would build up so much pressure that it would pop the dipstick out and if you started to unthread the oil cap it'd shoot up about 10 inches off the valvecover at idle.

the coils do not have a built-in ignitor i am using AEM ems and AEM cd2i. I have a post of my complete setup at http://forum.aempower.com/bbs/...light=
