Rice Racing M&W CDI COP Set-up

Wow, I didn't think it was possible to get them any more compact lol. That's pretty awesome.

Necessity is the motherfucker of all invention

[speedjunkie]

LOL it sure is.

I've said this about a million fucking times.... I REALLY hate making sparkplug wires.....

When can I order the COP adapters

Yes great idea, I did not think I can supply the COP adaptors alone and (IGN-1A) obviously and people can make up their own mounting arrangements

Just finishing off the design LOL (never ending story)!!!! last bit is O'ring sealing .....................

A cautionary note: DIY'ers

My system is precision, IE there is no real weight of the coil assembly on the spark plugs themselves, all of this load is taken by the engine mounting bracket and transferred through the coil mounts to the single fasteners for each module, the spark plug and coil end are 'rubber mounted' through the O-Rings. IF you are going to do your own mounts you will need to do it to precision to allow no loads on the plug ends.

Just a note when I was talking to M&W today (who is kind enough to send me his latest CDI bespoke coil) and I will be designing a system around those for EXTREME Drag and other highest power use that mandates a CDI system.

Here is a rough pictorial position relative to the front plate for those who like real pictures













These pictures show the aspects of my design that make it so solid!
The coils spacers are supported against a shoulder thus eliminating 'torque' related movement downwards upwards forces, and they both interlock against each other and butt up against the lower lug of the engine bracket.
Its unfuckable and very very strong, despite its compact dimensions and small fasteners

In for a set of the new compact design. I'll just make a bracket for my AC and alternator that clears the coils.

Lance could probably put together a coil with an end to mate directly to the spark plug instead of the HEI top currently on the coil. The expense you'll go through building what you have designed may warrant at least exploring a custom coil. He has many different versions of the coil currently. There may already be something in his catalog that works.

Any chance you can rotate the coils 180* to give more clearance at the front?

Love what you're doing here!

I know it would require redoing the block mount as well, but it would liberate more space.

Wayne @ M&W Ignitions is sending me his new CDI coils so I can do a specific design for these.

For the IGN-1A instead of a bespoke coil end, I'd like to make something that will suit the many thousands of coils out there? prob makes most sense as the coils are inexpensive and would appeal to a majority of people?............ I am open to ideas on that, but a few people like Okada Projects (now IP) are doing modified versions of these that are better than the original so I'd like to keep with using that as my 'Inductive COP option'

Swinging the coil to be vertical means more space, will require new coil mounts and engine mount, I'll work on another version see what I come up with and how fast I can do it LOL. The issue I see with this is the chassis rail as well as a stupidly long coil spacer/bracket though I'll do a quick model of it, but I think it wont really work well.

[RICE RACING]

Hmmmm, I'll have to sleep on this I think
Maybe should put some thought into trying to utilize the knock sensor mounting hole, but I don't really want to effect the function of the knock sensor (which would have to be repositioned) but it would get rid of all of the problems with different series of engines and center plates........

Dunno, I have the #1 design locked away (V2 OEM fitment).
This vertical iteration I don't like the long spacing of the coil, lower rail could be issue, I know on my last COP set up shit was very tight down there getting it on and off with the horizontal set up. The center mount would need to be much larger and I'd have to go with a 4 coil mounting fixing method to get over the length of a one piece mount with the coils mounted vertically.

My gut feel at this stage says that will be the option I stay with, sorry you have to modify stuff, but these coils are very odd in the mounting and size, I'll keep working on it and if I come up with something amazing will post it I could be wrong though, wont be the first time will explore the vertical mounting options.

[RICE RACING]

OK I have tried every permutation of angle offset on the COP adaptors and IGN-1A and stacking vertically is a fucking nightmare, because the coils are Asymmetric it means there is very odd arrangements for the Fr and Rr coil modules (and it just looks shit house as well). The is no elegant solution available around that coil design except to mount them horizontally as I have in my compact 2nd version.

If packaging space is an issue I'd say stick with ign leads and where ever you mount your coils, or go race car spec, or wait till I design the CDI (latest gen M&W coil version).

The IGN-1A style coils are just fucked for packaging as you can see. done the best I can with it, so unless I dream of a solution then this will be it for these........................

[almoststockfc]

I would be interested in the 2nd version. I like the more compact design.
