Coil...How hot

vipergts · Post by **vipergts** » Tue May 22, 12 6:45 pm

How hot should a coil get.

Mine is virtually untouchable. Its an oil filled jobbie

Its possible that its breaking down when its hot...revs drop and it pops and bangs.

Anyone tried placing it in a cool place?

If the coil gets to hot it would almost certainly cause a misfire and odd pop and bang, the question is why?

If its oil filled it should not be on its side in the stock location as this WILL expose part of the windings to the air inside the coil, and most assuredly will lead to coil failure, and component death.

What voltage have you going to the coil is the coil correct for this voltage?

They do run quite warm but should not be too hot!

Thanks Guy

It is indeed on its side....what you say makes sense.

Any suggestions on an alternative place?

I have checked the voltage back to the battery before but cannot remember what is was but changed the regulator as a result

All good now

Mine is mounted on the firewall. Some people mount them under the washer bottle on the inner fender. The choose is yours.

Really interesting.....whats the difference between these coils and 'normal' ones...How do I know if I have one of these coils or not? Pros/ Cons??

with all your money and extreme cars why is this charger constantly causing you running issues its so basic,
get someone at it that knows old 70,s cars it needs putting to bed so you have some faith in the car,

Derek and I where down there on Saturday just gone tring to sort it but now matter what adjustment we did on the carb it had no effect on the way it ran. The car doesn't over heat at all anymore and that was one of the main problems. We are going down tonight with my spare carb and a spare coil to sort this out for good. I thing the edlebrook carb that Lee has on the car is in need of a rebuild and to eliminate that from the problem I am going to put my spare carb and see how that works. I am also going to relocate the coil to a cooler place and stand it up right. All being well Lee will be driving the Charger to Brooklands this weekend. Will keep you posted on how thing go.

Bananarama! me.....you hit the nail on the head there.....tis exactly what I've been saying to everyone.

T|ook it for an MOT yesterday and everyone was having the full dribbleage at it...unbelievable.

It has been a real pain in the gary for sure but good old Anton is getting there.....a process of ilimination.

I'm pretty sure the electricals are breaking down.......lots of heat generated under the bonnet with open headers etc.

From what Guy is saying it could well be the coil. We'll see.

Would this oil filled coil have a built in ballast resistor?

I doubt it very much.

On a personnel note I would heave that helldbrook carbatooter in the bin I hate the damn things

but some people like them

I said the same thing about the carb.

I have put a Quick fuel on mine and it loves it

Carbs are carbs. They just allow air into the engine and add a little fuel as it goes. They don't even do it much differently no matter how the make.

When I first got my Challenger the Carter on it was knackered so I had it replaced it with an Edelbrock. I knew nothing at all about tuning carbs then (except for idle mixture) and when I had problems I tried my best to find an "expert" to fix it for me.

The best guy I could find (many years of car and bike racing experience) suggested I should fit twin SUs on my 318. Mainly because he was used to working with that type of carb. He didn't know where to even start with a 4bbl.
In the 30 years since i have found that people are always the same. They get their heads around one type of carb and make it work for themselves. But another type throws them and they struggle.

So I decided to buy a book on carbs. Covering all basic types from the very first ever invented to the most modern 80s carbs before everything went FI.

I then also bought books on Edelbrock/Carter and Holley tuning.

Within a couple of days I had my Edelbrock running sweet as a nut. When i then moved to a single plane manifold and hotter cam I found I needed to re-tune it and did so quite successfully. Although knowing what I know now with experience I probably could have got it running even better.

I do think a Holley is better for fitting to modified engines. That is because it is easier to adjust a holley for non-stock combinations.

But the Edelbrock/carter is still a damn fine carb for a stock/mild engine and has many features that make it a better carb than a Holley in those situations.
