Just wondering what sort of coils people go for in their I6?
ea/eb etc, not coil packs.

I was thinking since it's just a b**ch of a thing to get to, while I
have the head off I could upgrade mine to a Crane or MSD

Some say theres nothing to gain from the factory coil, but I'm
running LPG and it could do with a high performance spark

thoughts/comments?

Std coils are o/k but change their position closer to dissy and cooler location... If you want good spark then buy an MSD http://www.msdignition.com/ignition_1_5900.htm
Crane have similar product...

Im using the standard Bosch, IMO the mounts should be verticle as they seem to always crack at the mount holes thus allowing water in and then failing. The position is ok for heat as its on the intake side but again just the orientation could be changed.

how about this one?
the I6 coil has weird mounting position, haven't seen many aftermarket coils that would fit.

I use a Accel electronic with an MSD 6AL mounted the coil below the airbox with a longer coil lead .Works a treat.

OK, for years I had a full Crane HI-6 ignition setup - the box I had mounted on the fwd passenger side floor under the carpet and on the engine the std coil was replaced with a PS-91.

Never noticed any difference to performance.

Removed it all about 2 years ago and went back to a std Bosch coil - and have noticed no change in performance - car still goes like a cut cat - happily revs to the limiter and does well over 200kph.

Use the money somewhere else.

Accel 14008 Coil is excellent value for money.

Have used them on a number of cars with excellent results.

There's one under the bonnet of the Courier and it made a definite improvement. Fuel economy improved due to the fact that less right foot is needed. Then again, the original Rice Brand coil had over 300,000 klicks on it so damn near anything would have been an improvement.

In a previous life... I had the opportunity to try all of the MSD, Accel, Crane and Mallory coils on a test bed with oscilloscope and variable gap.

Using a ready-to-run MSD dissy, we trialled every coil we could find and found that the Accel coil threw the longest spark and gave the strongest output at the gap.

MSD Blaster and Mallory round canister coils were tied for second place.


I'll do a bit of homework and find what primary and secondary resistances are required for the majority of our applications. When I do, I'll share my suggestions with all who are interested in making their Ford operate more efficiently without spending millions on trick-of-the-week parts.

hmmm well its interesting that some people say they are a waste of time..

G'day JT,

If it's Accel you're referring to... Everybody's entitled to their own opinion.

I have no axe to grind with any brand, nor do I sell any of them.

All I'm offering is my own experience.

Personally, I hate a particular brand of spark plug leads yet other people I know and respect have never had a problem with them.

At the moment the Courier, the EF and my son's EA are all running Bosch caps, rotor buttons and leads.

Bosch make very fine coils but from my own experience a lot of people turn their nose up at them. No idea why. When the correct Bosch coil is used in the correct application, they're generally a very good, long lasting units.

The ute scored the Accel as I got it at a very good price.

I run a Crane HI6 and LX92 coil in my EL. It on the dyno added power down low (a tincy bit up top), and what you don't see on the chart is responsiveness.



But yeah, for the money, one of my more expensive mods.

G'day Datamine,

You've hit a very important nail right on the head...

RESPONSIVENESS.

The minor increase that shows up on the dyno graph wouldn't show up in the real world.

Point-to-point acceleration over a measured distance from a standing start, or an in-gear test over the same course will show what works and what doesn't.

Personally, I like the seat of the pants feeling combined with some form of measurable real world data.

With apologies to all the Dyno Demons out there, we don't race dynos.

Regardless of what ignition or coil you choose, the aim is to create a flame front that burns the fuel in the most efficient manner. Burn the fuel and the engine make more power.

A responsive engine is a happy engine.

Ask Jake to show you the ignition he's running on his turbo'd Torana or his turbo'd GSX11.

Who needs trick of the week?

I know Jake well, and we've both learned off of each other. He's got a Turbo EB Fairmont too.

yes well I'm well aware of the advantages of some aftermarket coils. When I built my 2L turbo OHC Ford capri I solved many problems by switching to a MSD blaster.

and on a back to back test the MSD produced a much fatter spark to the Bosh GT series cylinder coil.

But I am not aware of the Falcon ignition setup and deem it possible that the factory coil is pretty good to start with.? Unike my 30 year old capri..

So maybe a Crane or Accel would be worthwile. I have also read that LPG response well to extra spark.
