Flamethrower coil and magnecor leads
Discussion
Chaps
As part of my 'engine bay clean up' project this winter I have fitted 8mm Magnecor HT Leads.
First test drive and the 'pick-up' (is this torque?) was definately an improvement over the old leads...
Not yet fitted the Flamethrower Coil - due to put it on this week.
Will report back after another 'test' run on Sunday.

I fitted both flame thrower and magnecor cables and not had a problem. I bought the car with a HT lead problem so can't really say whether there was a megga improvement over the ones replaced all I can say is that I've not had a problem with both. Just love the fact that I have a flame thrower sounds cool I'll just get my 
The bottom line is it takes a certain voltage to make the plug first fire, and then the plug basically becomes a short circuit as the gas ionises and the spark starts. This could be around 10 - 20 kv ( you don’t need 40kv) depending on the engine load and throttle opening. Once the plug is burning, the rate the coil discharges is controlled by the resistance of the plug leads and plug caps, so say you put in copper leads with virtually no resistance, so the spark duration is very very short as all the power is dumped almost instantly. Fine if you are running a very high compression or specialist fuel, but not for a road engine that may need a longer spark duration to ensure the mixture ignites correctly. This is why road engines run high resistance leads, combined with the advantage of reduced radio interference. Magnecore leads are clever, as they have a wound core construction, that to a high frequency waveform look like an inductor, so it generates a back emf in the core and acts a bit like a resistive lead. This controls the spark duration without actually using resistive leads so less spark energy is lost. BUT it also can generate much higher voltage spikes on the HT coil primary, that can cause the rev counter to start jumping around, and you will find NO PROOF of actual BHP increase over decent carbon leads. Coil wise, doubling the coils voltage output is a bit like using 2 matches to ignite a bucket full of petrol, when one will do just as well, and it will increase the load on the ignition trigger system. Its defiantly NOT recommended on the V8 setup as the ignition amp is set up with a particular coil load / resistance, but I can't comment on the Ford.
However of course the car will go faster as your wallet is lighter !

A cautionary comment - maybe in your case it is due to the Magnecor leads, but when I fitted the bog standard RV8 set that TVR Car Parts sent me by accident (I have a V6 As part of my 'engine bay clean up' project this winter I have fitted 8mm Magnecor HT Leads.

) exactly the same thing happened. I think it was more due to the condition of the outgoing leads than anything special with the new ones.Chaps
Having fitted new sparks plugs, Magnecor leads and a flame thrower coil I can definately say there is an improvement.
That said, more likely due to the fact that the old sets were completely knackered!!!
Hey ho - as previously mentioned - less weight in my wallet now, so will now go faster anyhow...
