Hello, I'm going to mount those coils on an aluminum strut bar:
can I bolt them directly on it, or better to use silent-blocks ?
Is it necessary to connect secondary ground to head ?
TIA.

The coils are very robust, mount directly.
Many often use an aluminum thick wall spacer between the mounts
and the bracket.

The secondary ground MUST go the the SAME head as does that
coils plug wire.

The "est high" is for the 5 volt trigger "est low" is the signal ground.
(TPS ground, etc)

What is your dwell setting, will you "load MAP" the coils ?

Thank you very much, Lance!

Yes, i'll try to load map it on my M600. If you have any advice on how to map it, and how much bigger the plug gap, it'd be very appreciated. Regards.

First, the plug gap depends on maximum boost ?

The plug wires boot design is important, "'full legnth" with grease?

The dwell, low load, operation (2.0ms) then to 14 lbs boost (3.0ms) then to
28lbs boost (4.5ms), then to ???

A dwell of 6.0ms should do 45lbs boost with good wires, boots.

Use ONLY the dwell required, keep the duty cycle under 88%.

My maximum boost is 28 psi, and with the old stock single coil i had to use 0.024 plug gap on cold #9 NGK.
Plug cords are 6mm silicone from japanese Ultra, shorter one is 8", longer is 14".
The boots are 90 deg from Magnecor.
What grease should i use?
Thanks a lot.

I use, provide, Dynatex # 49635 Dielectric Grease.

The use of a product like this is the LEAST expensive item you will ever buy to provide
the greatest, simple fix,
for a high energy ignition system.

Does anyone have a dimensioned drawing of this coil?

The only way I could comment is to test the wire/boot, spark plug in my
pressure chamber@800psi of CO-2.

I would not use a "solid core" wire with EFI/DIS.

A picture of the coil is posted on the 034motorsport.com site.

Impossible to see from my pic, but it's not solid core (single wire), it's a 4 wires' braid... I measured it, and it's only 0.05" thick... Fingers crossed...

BTW... what a great coil it seems to be !

The M600, my '882, most EMS could "see" EMI, RF, energy created by your sparkplug wires pictured.

I use Magnacore carbon, MSD "ferrite", or mostly my own 8.5mm Ferrite
sparkplug wire.

I would like to see a picture of the boot AND sparkplug fitted together ?

Hi Lance, I've been away for some holidays.
Boot to plugs is this:



To fit the Magnecor coil's terminals, I spliced a longer piece of wire, blocked in the terminal, and after a drop of stain:





Thanks

Ask Motec if your "steel" wires will work, with my '882 it would not be the best choice.

The boot, if in contact with the plug steel body, could work better.

They worked with my Motec with the old single stock coil, so I presume/hope they'll still work!

Unfortunately it's too short...

Thanks Lance !

What gap could i try to use, based on your experience? Thank you.

I have a CO-2 chamber, the coil can fire a GAP of .080"@800psi CO-2.

What happens "IN REAL LIFE" is that the boot will leak, yours as shown has a gap between it and the steel.

That is the item, the boot is the limit or the wire is the limit.

I would start with a gap of .045" with 3ms dwell@"0" boost.

The boot you have could also "leak" into the head, it is very close to the body of the plug wire.

The energy will flow into the head, not the sparkplug steel.
This could be seen with the top of the boot removed.

Many times I have "seen" the high voltage "punch" a VERY SMALL HOLE through the body of the boot,
then into the head.

A common test is to LOWER the dwell, then if the missfire become less, you have a leak.

Nissanized,

I have to back up Lance here, I have Magnecor leads on my CDI set up that have a similar gap between the boot and the steel of the plug.

When I originally purchased them from Magnecor, I pushed them for a longer boot but was advised none were available.

My "real life" experience is that the spark with my CDI set-up jumped down the outside of the plug within a few days of use.

I now wash my plugs with electrical cleaner before and after installing them and also use dielectric grease to minimise the effects, but am very unhappy with the boots on my set-up.

I use a 0.045" gap and 35 psi boost on heat range 10 plugs.

I would be very interested if there is a boot that can be purchased to cover the plug completely.

Cheers

Hugh

Won't be possible to use some insulating material from the boot to the plug's metal?

Would it be the same to connect coil's "C" wire (ground to cylinder head) to my aluminum intake plenum? It would be a lot easier. Thank you.
