Title: nology coil Post by bobtreat on 01/15/06 at 08:32:41 I'm in the process of tearin down my 04 savage for a 97mm overbore,port an polish of the head and send the cam to web cams for a regrind.My question is about nologies hot coil.Will it work on the savage?They have a single tower,that with some fabin would bolt on.I just don't know if the resistance or voltage is the same? Has anyone added this?? |

Title: Re: nology coil Post by Jim_R on 01/15/06 at 08:39:57 Im not sure but I think its a great idea. Too bad we couldnt find out if anyone has ever used a msd ignition? |

Title: Re: nology coil Post by lancer on 01/15/06 at 14:20:32 I have wondered about that too, but have never gone far enough with the research to know for sure. It would sure be helpful performance wise. |

Title: Re: nology coil Post by klx650sm2002 on 01/16/06 at 01:28:36 I'd be interested in the Nology coil too as KLX's coil is a little weak. Clive W :D |

Title: Re: nology coil Post by orrin7 on 01/16/06 at 17:33:05 msd does have an ingnition and coil that will work and i am sure work well. i do not know the part numbers though. i have talked to a rep. and and engineer from msd and they said we could make something work. from another application. |

Title: Re: nology coil Post by theikeman on 01/17/06 at 21:23:13 If you know what the primary resistance (ohms)and secondary resistance of the stock coil is, you can match it with a nology of the same numbers. You also need to know if it is a single or dual fire. The Savage fires on both the up (fuel) and up (empty) stroke. The difference on the new coil will be higher secondary voltage than stock for a hotter, larger spark. You should also use a performance plug wire, as a standard resistor wire will reduce(resist) the voltage severely. Hope this helped. Ike |

Ike, can you explain this please? Steve |

Title: Re: nology coil Post by theikeman on 01/18/06 at 21:20:57 Ok, here is a little more detail. The primary resistance on a Savage coil is between 1 to 7 ohms and the secondary is between 10K and 25K ohms. So ideally you want a coil with a primary of around 4 ohms and a secondary of around 17K, anything different and you'll fry something expensive. Also, you cannot use a coil from a point style ignition. By dual fire I mean that the coil fires on the up stroke (the fuel mode) and again on the up empty stroke, when there is no fuel in the cyclinder. Get yourself an el-cheapo ohm-meter and test your coil. If it is outside of the ranges above, it should be replaced anyway. I hope this clarifies things better. Thanks Ike |

Title: Re: nology coil Post by SAMM on 01/18/06 at 21:49:27 Im confused ... Are you telling me the spark plug fires aprox. every TDC or every time the piston is on top ?? |

Title: Re: nology coil Post by Steve530 on 01/19/06 at 00:00:44 I thought the Savage was a single fire system. |

It's a dual fire - sparks on both up strokes - as are most, the ones that are not end up needing adapters and such for the after market tachs |

Title: Re: nology coil Post by theikeman on 01/19/06 at 07:26:21 High performance coil definition: Our stock coil is fine for everyday use. It provides a good solid spark to the plug. However, if we modify the engine or, the plug becomes worn or slightly fouled, the stock coil is unable to create enough voltage to keep our engine running smoothly. If we replace the stock coil with a performance coil, we get a much hotter spark. Why? How? Well, a performance coil has several important differences from a stock coil. A performance coil may have a larger iron core, more primary windings, better insulation between the windings and, many more secondary windings. The coil may incorporate some or all of these differences. The idea being to create a stronger magnetic field that is able to collapse (decay) quickly and induce a higher voltage through the larger secondary windings. The performance coils also have a much faster saturation (rise) cycle due to the improved insulation between the windings. All Harley models use the dual fire system except for the injected Harley models. You may be able to adapt one of those (single tower). |

Title: Re: nology coil Post by lancer on 01/19/06 at 07:50:30 The Nology coils I have in the book are as follows: DUAL TENSION TOWER ($80) -3.0 ohms -1.5 " -.6 " SINGLE SECONDARY OUTLET -3.0 ohms ..$92 -.3 " ohm primary (CDI) ... $101 -.6 " " " (CDI) ... $92 DUAL SECONDARY OUTLET -3.0 ohm primary ..$96 -.6 " " (CDI) ..$96 -.3 " " (CDI) ..$..? unk SINGLE COIL .3 ohm SGL CDI ... $101 Ike...can you tell from this info which one, if any, would work for us? Or do we need more detailed info? ***ADDITION: The wire is sold by the foot, and connectors seperately, so it is a "build your own custom wire set". The coils list for $80, 92, 96 & 101. The wire is$3.71/ft, and connectors are $12.64 for each end. If anyone wants a coil and wire/connector setup I will split the markup with you, which will end up being about 15% discount. |

Title: Re: nology coil Post by bobtreat on 01/19/06 at 14:00:27 Well it seems we're on to another hot topic.If I can't adapt or find a replacement coil,Nology does make a plug wire with a capacitor built in to increase the spark energy.It stores energy and addes it to the coils energy for a hotter spark.In my dennis kirk catalog the coils go for $71.99.I haven't found the plugwires singularly,maybe E-bay. |

Title: Re: nology coil Post by Jim_R on 01/19/06 at 14:08:20 maybe u can go in 3 other people and split the costs |

Title: Re: nology coil Post by theikeman on 01/19/06 at 17:26:37 Which of the above 3 ohm coils are single tower? One at that resistance should work fine, how about the secondary resistance? And ... what is the coilo utput to the plug, 40k 50k?? Ike |

Title: Re: nology coil Post by Reelthing on 01/19/06 at 18:06:45 but once you put in an IR plug that pops with far less doesn't that do about the same thing as a mild up grade in coil? |
|
Title: Re: nology coil Post by Steve530 on 01/19/06 at 18:20:04 Not to hijacek the thread, but is therer a noticeable difference with an Iridium spark plug. Steve |
