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) |

I am still trying to figure out why you want to use a dizzy and incorporate COP.
It sounds like a novel approach. Yet I don't get it. (nuthin new) You could accomplish a BETTER end result with electronics. Totally lap top programmable. And have the ability to change settings on the fly. This alone would pay for itself in saved dyno time. Imagine paying for hours of dyno time as you fiddle with a dizzy, it's curves and the inability to really change settings for a twin plug set up on a mechanical level unless you remove the dizzy and change the curves and tweak the electronics or a however you are going to fire the second set of coils for the second set of plugs. I bet the time wasted on this setup at a dyno shop at 125 - 175 $$++++ per hour would pay for a full Programmable Electronic ignition setup that would work better in the long run. Plus you would get a free EFI brain if you wanted to use the EFI functionality. I dunno... just doesn't make sense to me. If you want the look of spark plug wires. You can do what the 911 guys do. Many of them run the Electromotive Tech series brain and coil packs. This a known twin plug Porsche setup for six's. Works on 4s just as good. Electromotive specs The SDS setup will also handle coil packs for twin plug 4. Some fun stuff..... 356 twin plug Q&A Simple 356 twin plug data For me.. I would simply run the COP with a programmable ECU and be done with it. C |

C When I bought my LINK ECU (and Randal bought his at the same time from same place) the advice from Neil at Performance Developments recommended against crankfire and to use the dizzy (it is still laptop programmable)....the LINK supports crankfire at no added cost....also, I was "this" close to buying a MoTec, same advice from the local tuning guru...both felt crankfire was not worth the extra costs/troubles...and I'm sure you know Niel is an ex-Porsche Motorsports engineer (IMG:style_emoticons/default/smile.gif) For Jake or someone willing to spend hours on the dyno, I'm guessing that yes, he might be able to squeeze a little more from a crankfire, but at what cost?? aaron, that setup might fit in other dizzy's, I'm guessing they used the 009 as an example due to it being available brand new at a reasonable cost??? just a guess... |
