dual spark?

[burner563]

Anyone running a dual spark setup on a 403? What brand is best? Any feedback?

Dual spark as in 2 spark plugs and 2 coils? Like on piston aero engines???

I'm a little lost dude!

As in ignition units that fire twice on each cylinder compression. Maybe twin spark is a better description.

[bhm1712]

Twin spark requires 2 plugs per cylinder as in the alpha Romeo twin spark as they call it, and it's the same as a piston aero engine. I am not aware of any aftermarket ignition that can provide 2 sparks per compression stroke with only 1 spark plug. This would involve duplicating the coil and having 2 firing points. There would have to be a delay between sparks and this would mean the second spark would come after the explosion event and the piston would already be on its power stroke.

Ah right. A buddy of mine had a 78 t/a and he said he had one. I shall ask and report back

Do you mean " Dual Point " Ignition ? As for Splitfires, i knew someone that was sponsered by them, but he didnt run them as he said they were sh*t . Not only did he race, but him and his dad are well known engine builders and tuners too, so i took his word as spoken.
