Its designed around 13B-REW, I could do a redesigned engine mount for other applications (need to be careful about rotor housing and spark plug location as well! *have to check this* may require coil brackets redesign as well!), but need some details sent to me on the config, all my old stock of plates etc long gone! LOL

If you're willing to make another design that would be great, I would be more than happy to set my SakeBomb coil mounts to the side for a product like this.

If a possibility for you, count me in. Whatever you need from me let me know and I'll do my best to assist you.

I would be interested as long as there isn't a drop in efficiency because of the small contact point. Can I ask why there is so much excess material around the coil mounting tabs? Is there a reason?

[TitaniumTT]

That's a good point, different series housings had different spark plug locations, and different center irons had different mounting tabs..... Damn rotaries

Hi,

When I was working as a teacher in Automotive I got to look at all kinds of COP set ups, I was shocked when I saw all they used to create a contact was a small coil spring! when I made my fist COP set up (search the net) I custom made my own springs similar to OEM and under the PECO scope analysis there was no drop in Kv (use magic wand probe), and over the course of a few years testing in field they were faultless.

This system of mine is far improved in that it accounts better for miss alignment but also uses a bespoke spring (me and my father manufacture these!) with much higher pre load assuring a positive constant electrical contact a permanent one. IF you pull apart many OEM and after market wires and see just how fucking shit the contacts are on the posts of coil and plug you would be shocked what you find, at any point they are just single point contact but with VERY POOR clamping to either item! they really only work with the rubber boots creating the constant load to keep them in touch with the mating parts......... very poor system.

In regards to the 'excess material' on the coil 'F' and 'R' brackets, that is because there is an offset to the Trailing coil has a +4mm offset and this is reflected in the mount, to save me standardizing the COP adaptor (preferred) I decided to have offset coil mounts (so this is why one side lines up to the coil tab on the top coil and the other side lines up the the coil tab on the bottom coil, this could be machined off but then it would look line a leaning tower in Italy so best to leave it as is.

Hope that explains it.

Oh and in regards to making other stuff to suit other engines.
I would need confirmation of the plug locations (FC housings) as measured from the bottom edge, also a mounting location on the center plate, and a verification of the T & L plug recess in relation to the mounting point (best to email me) as I would send a drawing of what you need to provide me to design it to suit your application).

If I still want to mount my ac compressor and alternator on the side of the engine, with I have room?

I can give you the horizontal dimension (to the left) or FRONT of the rotor housing edge and you can confirm yourself if it will fit the parts on your motor set up..

This is the dimension (front of rotor housing edge)
9mm+17.14mm = 26.14mm





This is dimension from tip of Trailing plug (R7420) to the tab on the top coil *sticks out furthest* ref GREEN shaded areas
45.75mm

[RICE RACING]

Another dimension of how low it sits so you can determine if it will fit your set up.
Center of Trailing plug to bottom of IGN-1A coil
105.88mm

[Monkman33]

Thank you!

I will check it out.

Damn I hadn't thought about the AC compressor and power steering. I'll take measurements when I get home.

Yeah shit was designed around 'race car' spec set up,

However if there is enough demand and it wont fit I guess I could spend some more time of my life modifying the solution to suit more OEM set up.... it all comes down to feedback and dollars (in orders from people who want it to suit there set up).

I'm pretty confident this will fit all, but that counts for shit till some of you c-u-n-t-s measure it up and let me know

On my old kit I have a WI tank where all of that OEM shit went and the COP fitted perfect, this one is not much different (even more compact) as I actually designed it rather than making from bit I had lying around LOL.

[RICE RACING]

This is the old set up, very simple compared to this.
You will see I have designed it for coils to sit lower (run cooler) and also clear rear heater water outlet.

Anyway some pics for reference for those who have not seen this before.

Would have a bigger market if it fits behind factory ancillaries.

Might be able to get some rough measurements this week.

Thanks for that.

Open to ideas thus the thread, at this stage in design can redo items if needed to suit the majority as all of it will fit mine anyway.

Just means I'll get faster on the CAD haha

[MotoTek]

Great design! I have a side mount alternator, so not sure this will work on my 20b unfortunately.
