Does My Coil Look Big In This ?

[rfs1957]

Am cheating a bit here, by adding a post that is parallel with one I've put on the Megajolt thread, but as the question relates to finding space for the coil, some kind folk with no particular interest in the Megajolt yet might be able to help with advice about what components I've overlooked in this mock-up.

I wondered if some of you would have a look around your oil-filter / air-filter / engine frame areas and help me firm up my coil-mounting issue.

I had made brackets that sat the coil on the long diagonal round tube, but that didn't work.



So now I'm having another stab.



I've mocked up motor and engine frame, this shot shows the RH engine frame in the right place relative to the engine, oil-filter, air-filter tubes, etc - please, is there anything missing that I'm going to get snarled up with ? !



I've not put the steering column in because I believe I'm way clear of it.

This is where I'm hoping to tuck it away.







Are there any maintenance access issues I've not considered ? Getting the oil filter out won't be as easy but removing the air-filter canister ought to solve this.

All and any comments most welcome.

A couple of points to consider. Later cars have a mud shield in that area, which protects the air intake. It wasn’t on the early cars as built, but I think it was suggested as a potential retrofit by the factory. With the coil pack there, you won’t be able to fit it. Fitting the coil pack so low also potentially makes it vulnerable to getting wet if you drive in heavy rain.

I wondered if..........hint of desperation...lots of lovely pics........

All and any comments most welcome.

Hi Rory,

Struggling to post pics (forum post image) for some reason and Imgur has gone to pot.
Looking at mine I can't seen any obstruction issues other than possibly brackets for splash shields. Low down water ingress might be a problem and potential fuel leaks from the carbs.
Have you considered mounting it on the picture frame as per the later S2 coils or is that aesthetically out of the question?
If you are set on mounting it as pictured, perhaps make the brackets to sit at 45 degrees inboard to the top of the frame so the leads clear the tube above. Knowing you as I do, you've probably thought of that already.
I'll email some pics over.

All the best,

Simon

Hi Rory,

Have you considered making up a blanking plate and mounting it in the same place as the distributor?

[rfs1957]

Indeed had considered doing so, Paul, but am intending to keep the distributor both for its appearance and as an electronics-free backup system.

Yes, Okay, I'll confront disguising the 12 plug-wires when the time comes.

It's like, yeah, twin-plug, two ignition systems with staggered timing, right - Cont. page 93

.......but taking that thought further, is there not room for the coil tight against the side of the block between the distributor and the oil filter just below the block/cylinder head join? A suitably bent bracket could then pick up on the lower inlet manifold bolts. The heater return feed pipe might have to be modified or replaced by a rubber hose. The plug leads would emerge convincingly close to the now standby distributor.

[rfs1957]

Yes, it's easy to find space for it somewhere - certainly where you suggest, John.

But when you've gone to such lengths to hide the brake servo, for example, and made brackets like these, you're on a road where angle-iron and convenient manifold studs are no longer on the horizon.





You want a pick-up support for the toothed-wheel ?



Madness, I know.

I believe it will fit discreetly where I've suggested, with minimal brazing of the requisite support lugs (the whole front end made out of brazed Reynolds 531 or equivalent), with reasonable cooling, access for replacement isn't too bad, cable routing is good etc

I just need to be sure that there isn't something else that's meant to be down there !

NB - the toothed pulley is very close to the sump in this shot, since corrected and now around 1mm.

Hi Rory,

How did you mount the trigger wheel on the back face of the crank pulley? That looks very neat.

[rfs1957]

Tom, this is as-yet unproven.



But looking good.



You can follow the thought process and then the execution on posts #425, 428, 429 and 432 of this thread.

I should have gone a tad deeper (extra 0.3mm ?) when rebating the rear of the damper, as this would have given me more clearance against the sump.

But I had already modified the ProRace (vile name) damper anyway

so it was my fault from A to Z.

Thanks, looks like a well though out solution.
