Rice Racing M&W CDI COP Set-up

[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........................

That's 90*. I said 180*. . In the original version the long side of the coil is facing forward. Flip it so the long side is toward the back. My guess is it still won't provide enough room for the AC compressor. I tried this a couple years ago. It's tight in there!

See what I can come up with, this way will clear as best it can and not interfere with heater coolant pipe as well, otherwise I would have spun it other way!

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.

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.

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

[infernosg]

I'm paying attention. Chris (Ludwig) knows a setup like this would benefit me. It's too bad the Series 4/5 center housings don't have that little bolt hole though. Using the knock sensor hole isn't a bad idea for those using a cheaper engine management system like me.

[Fendamonky]

Looks awesome Peter!! Count me as down for the compact V2, adapter and mounts =)

[infernosg]

I'd be interested in just the COP adapters. I have a Series 4 center plate without the center mounting point so the interference isn't really a problem. I'm sure I could come up with something that uses the knock sensor locations.

So it's confirmed that the PS and AC pumps would be in the way of this on the REW?

I don't think anyone has validated that yet?
I do have all those systems stored away, if I get time will pull them out and mount to front plate and have a look physically at the potential interference



These coils are shit for fitment, so looks like V2 system is for people who are willing to move shit around to suit or run a car that is more 'race spec'

ONLY thing I can do to try to suit (well at least a 13B-REW rotor housing) is go for a knock sensor based central mounting method, this means can use the system on 1,2,3,4,5,6................. 25 rotor applications with ease, Will stack these coils 'vertically' and come up with a system like that, I think I will do the same with the M&W CDI coil as well, however! its got its own issues.

p.s. That shit wont work, I can run an analysis on it but will have to run a 'stupid' size mounting system as there is a big canter lever effect from that fixed point, would be vastly more complex as well I wont totally dismiss it, but my brain is telling me its going to be an abortion.

[RICE RACING]

I have thought of EVERY permutation and the below is the ONLY one that is viable, need some input if people are interested in me developing it?
Involves cutting off one of the tabs on all four coils (simply at the edge of the sleeve), then it will allow placement as per below and clear everything.

The coil bracket spacers will be 154mm long between centers and obviously new (13B-REW) engine bracket required.

I'll start fucking around with it anyway to show what I am thinking and that way you can decide if its what you want.

Oh OK. The reason I said that was because Monkman was talking about making brackets to make it work for him, so I assumed it didn't fit. I'm certainly not asking YOU to do it, not after all the work you've put in already. If I was home I'd check on it myself. Honestly I like V2 the best. I doubt it will ever get more compact and optimized than that. I honestly think it would work with the AC and PS too, but maybe not. I'm not home to look at it. I'm planning on using dual knock sensors so I wouldn't get that one anyway, even if you did make it. So if V2 doesn't fit, oh well. I guess I'll have to pass. I'm hoping it does though.
