Lance, if the boot is not able to reach down to the metal of the plug, what is the best way of trying to contain the energy?

Slightly excessive amount of die electric grease, what let irons are there...

Spark Plug Boot Design
 

FIRST, my data is MOST OFTEN observed, tested, retested, by the use of my CO-2 Spark Plug pressure chamber firing bench.
This allows for ACTUAL running engine test conditions without damage to the engine.

I have NEVER tested a "dual" boot design. (two boots connected at a parting line)

MY reason is the development of the FireCore 50/250 8.5mm spark plug wire showed HV leaks with others 10mm wire.
What was found: When the insulator diameter was increased from 8mm-10mm, a greater chance of a "pin-hole" size hole was present.
ALL who produce the silicon jacket over the wire conductor have the same problem, its just that the 10mm size allows for the pin hole to be more common.
This "pin-hole" allows the HV to leak out into the air with lower energy passed to the end of the wire.
The WITNESSED observation is seen as a Corona on the outside of the wire.
I should add that my tests where with the use of the IGN-1A coil@400psi. of CO-2.

Reason would state ANY tear, pinhole, cut, "dual-boot" design would cause a HV leak.

Unless you use a simple amount you would always use of Dielectric or Moly compound. Like you would on any ignition system. Especially I High Performance Ignition..

Use common SNES and you will have no problems.


You forced conditions with an airgap if the airgap is sealed it will not happen correct?

Pressure Test of Plug Boot
 

Correct ? : UNKNOWN

One method, my method, would be to do the test using my CO-2 Chamber.

Would you be able to set the parameters for YOUR test ?

Lance

Its as simple as driving and inspecting the ignition system for Carbon Tracking.

It is very simple to see and to fix the issue. I think I read it in a book from the 50s.

Part of proper regular maintenance.

So... any news on the ETA of these? Anxiously waiting as I HATE my current lead configuration!

Yep, same here. . . :toetap05:

Yes I know........
Had a slight delay, have been doing heat treatment of springs (job in itself) as I do all of them myself.
Hoping this time next week I'll smash up a completed assembled IGN-1A unit and for those who have asked me for COP Adaptors and complete units will then take an order and get there items made.

To make them after the first runs (which I am testing) is pretty straight forward process, hopefully more speedy.

I appreciate your patience. I am as keen as all of you!

Engine Miss-Fire Detection
 

The "frankenstein" effect (Carbon Tracking) WILL cause miss-fire which is VERY DANGEROUS to ANY engine.
Constant engine miss-fire causes the "trace" of a conduction path to be easily observed after MANY firings creating the ground circuit destroying the plug boot.
Many times this was the cause of a "blown-up" engine.

WE see the result of miss-fire in the GUI of my ECU-882C after counting the acceleration rate of my 60-2 crankshaft TW.
This is at the first miss-fire hopefully before engine damage can occur.
We have used this method for OVER THIRTY years, as due all OEM's from 2006 on as the patent expired, its the law.

MY hope for those users here that may fit my coils is NOT to explode their engine.

Thus my offer stands, I will gladly test a boot/wire/etc. in my CO-2 chamber without damage to a running engine.

Lance

What coils are those Lance?

Perhaps start a different thread where you can go deep in the weeds on this subject (as you're obviously passionate about it) without necessarily derailing the current thread in the process.

IGN-1A Coil Boot & Bracket Design
 

Hi Levi, THIS thread is about Peters coil brackets AND boots for the IGN-1 coil family.
The brackets he machines look to be fine !

HOW am I "in the weeds" ?

Lance

Your initial concern, that Peters COP adapter didn't form fit to isolate the steel tip from the insulator, leaving an air gap has been addressed by Peter. Since then just about every post of yours so far has harped on YOUR CO2 chamber, YOUR extensive testing, and/or YOUR coils.

Your posts have left the original subject of this thread and are meandering over to your own subject. This is not necessarily a bad thing, but I think your subjects warrant their own thread instead of piggybacking on Peters thread.

That is how you're wandering "in the weeds" :biggthumpup::cheers2:

ok I have all parts finished, will take some pics later on today my time, busy with seals that have to be sent to customers so this will have to come second.

*they look great* and work nice :302:
later today/early tomorrow will get in touch with customers who have emailed me about various systems and parts to organize their items, thanks.

Peter

your mumma

Stuff looks great! now. . .
