EA81 Dual Coil Dizzy Mod

Found this on a subaru aircraft page:
http://jordan.snides.net/Image/subaru/ea81_dualcoil.exe
It's a pile of pdf pages in a self extracting rar file.

What do you reckon?

can't see it

i've been waiting for someone to try this!!

My bad, Fixed.

wow. a bit advanced for me. i dont like the idea of modifying my dizzy for it though.....

i think 1 x MSD Blaster 2 should suffice

Yeah I definitely wouldn't be doing it to my only dizzy.

Doesn't seem to complex, I wouldn't mind giving it a go, I spose my real question is would the gain be worth the effort.

In theory running 2 MSD Blaster 2's on this setup would give you some serious spark power and therefore some serious performance as well as pretty good redundancy should 1 die, but in practice how would it go?

i assumed it was safe to run that exe as you guys must have....
normally avoid running any exe that you just download, so easy to add a virus to them.........

anyway thats interesting on last page about adding a heat sink to the modules...didn't think it was changing their power dissipation....

anyway i'm just suggesting that maybe have the dizy drive 2 coils in parrallel, with that heat sink mod......not that I need to try that with my setup, just seeding the idea for someone else :P

some serious spark power and therefore some serious performance

I read elsewhere, once the spark (at whatever energy spark you got!) ignites
the fuel, a more energetic spark adds no more power/performance

I'm just guessing here but I think you'd widen the plug gap at the same time so it comes into contact with more air / fuel mix.

With that much power you'd be able to run a huge gap!

The wider the gap is, the higher the voltage potential required, before the spark gap will break down and arc., so no you can't run a huge gap.

Dual coils in parrallel will not really increase the voltage, but would give
a "hotter" arc once the arc starts, ie more current.

After some thought i came to the conclusion that, seeings how it's on an aircraft site, the mean purpose would be the redundancy more than anything else.

hey has anyone got this saved on their computer?
can we upload it to aussubaru?
the other site is gone now

Spike it took me a while but I found this page I knew it was still around

an interesting read
