Hybrid_From_Hell Posted September 9, 2011 Share Posted September 9, 2011 OK The 5.2 is coming along after a gap of other stuff that got in the way. I am doing several things at once on it, and the V8 Porn Thread will be updated soon Anyway, I have had to make a special Coil Pack mounting for the twin coil packs - being the trumpet / plenum is special niothing I have fits, so its DIY Time and is done Basically I need the forums help with Coil Packs and the plug leads and their routing Below is a picie of the setup, it shows the left hand bank of the engine with 2 4 6 9 cylinders and the right hand side with 1 3 5 7 The 2 x coil packs have the fiting outputs shown on them, what I wnat is the forums input as to the best wat to rearrnge the coil numbers to gibve me the neatest routing Now the tech bit The coils fire in line and if you like are "Banked", so if we take the top on RHS (Nos 4 & 7) these are "Linked" So, to explain what can / can't be done Coils have to stay in their positions ONLY LINKED pairs can be moved, ie you can swap say 7 & 4 with 6 & 1 You can also swap link number around ie 7 & 4 can be swaped to be 4 & 7 All Linked numbers can be moved All linked numbers can be swapped with each other So, competition time ! Please post up your best routing - this should be the least amount of leads crossing each other, however there is room for you to pass lead within the unit, to explain I have shown the routing on the eales - which has only 1 x wires crossing over HELP - I have been at this for hours gotten not very well so need forums help !

Bowie69 Posted September 9, 2011 Share Posted September 9, 2011 Stupid question, why not just use the Eales layout on your 5.2? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 9, 2011 Share Posted September 9, 2011 How about this? I turned the coil packs upside down.... no cross overs. Free built megasquirt kit? Why thank you Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted September 9, 2011 Author Share Posted September 9, 2011 Cos the eales unit was a huge mess and was at the back - right where the airbox would be ! Mr Eales builds beautifull engines, but leaves exhausts airboxes and things like ignition layout to the buyers ! WISE MAN ! Have looked at your solution, best yet - some of the wires (Like No 1 is a bit torturous, but a stong winner so far Come on you high visual Acuity Members - bring on the solutions Nige Quote Link to comment Share on other sites More sharing options...
landy V8 Posted September 9, 2011 Share Posted September 9, 2011 nige i've come up with this 8 7 8 7 obviously above and below 6 4 5 5 6 up and round between 4 and 5, 5 to 5 4 3 6 3 4 to 4 3 under 6 2 2 1 1 2 to 2 1 to 1 hopefully you'll understand how i mean as i don't know how to get that diagram.(not the best on computers) ralph Quote Link to comment Share on other sites More sharing options...

zardos Posted September 9, 2011 Share Posted September 9, 2011 OK Below is a picie of the setup, it shows the left hand bank of the engine with 2 4 6 9 cylinders and the right hand side with 1 3 5 7 Must be a very special engine with no cylinder 8 and an extra ninth cylinder Quote Link to comment Share on other sites More sharing options...

landy V8 Posted September 9, 2011 Share Posted September 9, 2011 trythis then. Quote Link to comment Share on other sites More sharing options...
zardos Posted September 9, 2011 Share Posted September 9, 2011 Landy V8 yours and mine look very similar, they use the same principles and it is sort of an upside down one of mine. Though I did not look at the other attempts before I did mine. Quote Link to comment Share on other sites More sharing options...
landy V8 Posted September 9, 2011 Share Posted September 9, 2011 i thought that when i saw yours after i put mine up.if Nige has spent ages trying to find a solution how come we came up with similar variations pretty quickly. obviously great minds think alike.

ThreeSheds Posted September 9, 2011 Share Posted September 9, 2011 Never had a problem with leads crossing when using decent quality leads (which I am sure you will be doing)... Is this something I should be worried about? Roger Quote Link to comment Share on other sites More sharing options...

Hybrid_From_Hell Posted September 9, 2011 Author Share Posted September 9, 2011 Leads crossing is one thing Leads crossing (however good a quality) 'fully submerged' is another As I now have 1000 Metres of nice Blue Ignition lead Edis ends and plug ends etc to play with it DIY time mit some "Stock" Keep the ideas coming Nige Quote Link to comment Share on other sites More sharing options...

zardos Posted September 9, 2011 Share Posted September 9, 2011 Moderator this thread should be in the MegaSquirt section, shame on you Nige And to add to this competition how about a better layout for the even bank rocker cover mount position shown in the MegaSqurit Mega thread. Blank below Note the coil packs are shown in the middle for ease of layout (their actual location is to the left) Initial layout shown in thread Any better ideas?

landy V8 Posted September 9, 2011 Share Posted September 9, 2011 Zardos if that the case then you could do it like this. Quote Link to comment Share on other sites More sharing options...
zardos Posted September 9, 2011 Share Posted September 9, 2011 Zardos if that the case then you could do it like this. Hmm You have broken rule number 1 "Coils have to stay in their positions" and rule number 2 "ONLY LINKED pairs can be moved, ie you can swap say 7 & 4 with 6 & 1" Quote Link to comment Share on other sites More sharing options...

landy V8 Posted September 9, 2011 Share Posted September 9, 2011 nah,our first 2 versions are better as they are more direct with only one none direct path Quote Link to comment Share on other sites More sharing options...
zardos Posted September 9, 2011 Share Posted September 9, 2011 nah,our first 2 versions are better as they are more direct with only one none direct path that last attempt was for a different coil layout to Nige's (my competition part 2) Note the coil packs are rotated to point to the odd bank, not backwards and forwards as in Nige's request.

TSD Posted September 9, 2011 Share Posted September 9, 2011 At the risk of blowing Niges mind... (and as other have said if you aren't using magnetically shielded leads like Magnecors) Remember that the only lead crossings that really matter are the ones where it risks coupling into a cylinder that is about to fire (because those are the ones containing a burnable mixture). So with firing order 1-8-4-3-6-5-7-2, lead #1 shouldn't cross with #2 or #8, since coupling from #2 might fire #1 early, and coupling from #1 might fire #8 early. But crossing #1 with #4 or #7 is much less likely to have any detectable effect. however... EDIS is a wasted spark system, so #1 and #6 fire at the same time (crossing them should have no effect, but there's no need since you can swap the leads on the towers), so you shouldn't cross #1 with #3 or #5 either. So if you have to have leads crossing, there are good crossings (e.g. #1 with #4 or #7) that wont have much/any effect, and bad ones (#1 with #8, #2, #3 or #5) which you should avoid. Back to silent mode... Quote Link to comment Share on other sites More sharing options...
ThreeSheds Posted September 10, 2011 Share Posted September 10, 2011 Are we allowed to take one lead around the engine under the sump? Quote Link to comment Share on other sites More sharing options...
