I have seen the twin spark dizzies. Straight forward.
Then there are the crank fire twin pack setups. ok. what else can be used? Piggyback systems? (picture is for entertainment purposes only. this is not my motor) Attached image(s) |

Our esteemed Mike Mueller and I had a conversation about this very idea a couple of months ago. I think it's a valid idea, worthy of investigation. The COP angle is a good idea. Should make triggering the spark a little bit easier. But I'm confused, if you have COP, why do you need an 8 post distributor? 4 posts for the 'traditional' spark plugs, COP for the inductive trigger spark plugs. Git 'er DONE!

(IMG:style_emoticons/default/thumb3d.gif) This is exactly what my idea was. Stock 4 post distributor and ignition for the main plugs, slip on an inductive trigger to each "existing" wire to fire the second plug, which is powered by a COP. My original thought was that it would remove the need for lots of plug wire running, and the extensions on some of the COP's would allow it to reach the plug up under the head. Hi temp wires and converting the distributor would cost more than this idea I think. Simple trigger. less plug wires means lower maintenance costs. My 1.7 is using the stock DJet system for ever, and is the motor that will be finished first and back in the car first. Otherwise I'd be looking at distributors that dont need the FI trigger switch. Clayton- The first photo was just a cool pic I found of a twin plug engine. The second and third were just pictures of COP's and an inductive trigger (used the timing light image so people would grasp the concept) to illustrate what parts I was thinking of using. Further, I wanted to keep my original 1.7 "stockish" looking since its the original motor for my car. 1.7 tin, but bad plug angle. So I went on thinking and thought that I could add the second plug underneath, and link them up without much hassle to improve the spark. I'm going with HIgh compression PC's and 9:1 ratio, so I think better spark would be a +. I realize its not as "trick" as the modified cap and twin coils, but this would provide better spark and reliability (maybe?). And maybe lead to other upgrades later if I make the choice to go EFI. |
