volflo Posted July 27, 2004 Report Share Posted July 27, 2004 Since i have gone through a bad misfiring at full boost and already changed my complete 6 wires of the ignition, im thinking of finally going with new cables:But which ones to take? are they both easy bolt ons? are the KV85 Comp 8.5mm worth the extra 20 Bucks?Will i be able to upgrade afterwards with e.g. Jacobs without changing again?WiresThanks, all.

JDELUNA Posted July 28, 2004 Report Share Posted July 28, 2004 I think the thickness of the casing is only for heat protection purposes only, I would go ahead and pay the extra $20 just to be safe, can never be safe right ?? I forgot where I bought my Magnecore wires but I remember paying less than $180 for them. They will probably last longer the vehicle, as for using it with the Jacobs system, you should not have any problems that I can fore see. Good luck and God Bless.

ontheheel Posted July 28, 2004 Report Share Posted July 28, 2004 is that .5 mm just extra insulation or is it extra wire thickness itself? if it's wire thickness, thicker wire=less resistance. Link to comment Share on other sites More sharing options...
Guest DougK Posted July 28, 2004 Report Share Posted July 28, 2004 is that .5 mm just extra insulation or is it extra wire thickness itself? if it's wire thickness, thicker wire=less resistance.←Its both. Even if it was just extra insulation, this would help prevent spark jump and other "spark contamination" Should be a thicker core though. Link to comment Share on other sites More sharing options...
ontheheel Posted July 28, 2004 Report Share Posted July 28, 2004 what is spark jump? Link to comment Share on other sites More sharing options...
Guest DougK Posted July 28, 2004 Report Share Posted July 28, 2004 what is spark jump?←Lets say you have two cylinders that fire right after each other. If you run the two wires parallel, the spark can jump from one wire to the other. I know it sounds stupid, but its true and it DOES happen. The way to avoid this is by crossing the wires (that relate to cylinders that fire one after each other) and a 90* angle. Let say (going from memory and a random guess) your firing order is like so:1-3-4-2-5on 3 and 4 you'll want to cross the wires so that it doesn't jump wires and fire the wrong cylinder.

ontheheel Posted July 28, 2004 Report Share Posted July 28, 2004 cross the wires? as in twist the boots to different angles? or are you saying do something like take a zip tie and make an X somewhere between two wires? i am a bit confused Link to comment Share on other sites More sharing options...

freeskier8585 Posted July 28, 2004 Report Share Posted July 28, 2004 sweeet im gunna fix mine, just use a zip tie? Link to comment Share on other sites More sharing options...
Guest DougK Posted July 28, 2004 Report Share Posted July 28, 2004 sweeet im gunna fix mine, just use a zip tie?←You might have too... you should be able to just play with the routing and wire looms and make it work. Link to comment Share on other sites More sharing options...

WITHOUT removing the spark plug cover and ;yes, without drying the stuff afterwards. on full throttle i.e. high rev the spark would walkk thru all the wetness from one cyl to the other. i can tell u, that sounds like an AK47.

volflo Posted July 28, 2004 Author Report Share Posted July 28, 2004 http://www.pbase.com/image/31892960←i see ur point. but why then do we have those UUUUU-shaped plastic things the wires run through? (and after first cylinnder its UUUU, after 2nd UUU, .......) Link to comment Share on other sites More sharing options...

Thickness of the insulation is important.Either way go for the thicker ones. Link to comment Share on other sites More sharing options...
volflo Posted July 28, 2004 Author Report Share Posted July 28, 2004 DONE. Ordered at Marc. (Tweety, Sylvester)Thanks all for the quick and sophisticated help.
