Good morning all. I recently fitted pertronix electronic ignition and flamethrower coil and also a dizzy refurbished by the Distributor Doctor. All works well but the coil gets very hot. So I am considering moving the coil to the bulkhead. I am after some advice on where could be a good place to fit it and I assume I would have to drill some holes through the bulkhead somewhere accessible to attach the bracket. Any advice would be welcome. Thank you.

I don't think it should be getting very hot. Thousands of them work perfectly well in the "V" but ideally when raised up so that it is not sitting on the engine block.
Did the DD advise you to move it?

Hi Mike, no they didn't. But it does get quite hot especially when its been ticking over for 10 minutes or so for example in traffic. I can just about touch it when the engine is up to temperature.Comment

Do you still have the original type engine driven viscous fan fitted, and is it in good condition?
I have the same setup as you and, although the coil does get warm, I have not noticed that it is too hot to touch. Mine is the oil-filled Flamethrower coil as the resin-filled Flamethrower originally supplied by DD failed and was replaced by the oil-filled. My coil is mounted on the back of the inlet manifold with the bracket clamped around the base of the coil so that there is a considerable gap between it and the top of the engine block.Dave

Hi Dave,
I have renewed the VC since I fitted the coil as the original was not working properly. In fact I have fitted two VC as the first one had a bearing fault but it was replaced immediately by the supplier. So I now have a good flow of air around the engine bay which should help reduce the temperature of all components. I shall monitor the coil.
However if the coil still feels hot, I don't think it would be too difficult to move it to the adjacent bulkhead and would be a little cooler environment.Comment

Hello, I have moved my ignition coil to the rhs inner wing - where it is much cooler. But then you need longer leads.
Best wishes,

I just positioned it higher in its bracket from the block and used a heat reflective tape wrap on the coil bodyComment

I see a fair few stags where the coil is just touching the RH driver side head. don't do that. give it as much space as you can as V8burble and others have said. Inner wing positioning might work but again a lot of engine bay heat to deal with, Bulkhead is a sensible idea if you no longer have a viscous fan.
And on that note I am firmly at odds with the "viscous fan delete" idea, cuts down on what little engine bay air movement there is and then for the extra kick to the sack, blocks off air flow to a big chunk of the forward face of the rad with the electric fan and bracketry. Then folk moan like hell that strommies are crap because the fuel is boiling away from the float chambers etc
Like so many of these "upgrades" I remain to be convinced

I have just fitted a new viscous coupling and a new fan. I think for the time being I will position the coil higher in the bracket and see how it goes. Thanks all for the replies.Comment

I have just returned with my new hood and frame from South East Trimmings (lovely job by Jim and his assistant - sorry did not catch her name). This entailed a trip from west sussex to near Faversham in Kent avoiding all motorways. It was just over 80 miles each way with about an hour in between for the fitting of the hood and frame. I was averaging about 50 mph with a few bursts of 60 and one of 70 on a dual carriageway. I checked the temperature of the coil on arrival in Kent and it was under 50 deg C. I attribute the lower temperature than I previously recorded which was over 60 C to better airflow in the engine compartment due to the newly fitted Viscous coupling and new fan, the raising of the coil in its bracket ( although it was never touching the cylinder head but was closer to it) and the longer run at higher speeds than my normal pottering to car meets near home. I also checked it when I arrived home after being stuck in a couple of hold ups and it did reach about 60 but I am happy with that.
As an aside, this was the longest run I have done in my Stag and since I have fitted the Distributor Doctor Dizzy fitted with Pertronix Ignition and Flamethrower coil, plus refurbished carbs and the new VC and fan and having fitted new plugs and reset the timing slightly. The temp gauge was mostly about 1/3 rd of the scale rising to just under half when in a couple of hold ups but then returning to the lower level. I have standard cooling system. Another marked improvement was the fuel consumption. In my previous about 700 miles I have been averaging less than 15 mpg probably due to the carbs worn needles and jets. But although I am aware that the fuel gauges are not necessarily very accurate I made the 160 mile journey and the tank indicates exactly half full. I will have a better idea when I next fill up but this is a massive improvement evn allowing for the long run.
Apologies for long post.Comment

Happy days ... the weather in the south-east (at least in Essex) has been great today, I bet it was a good day out
