What difference if any would this make to the performance if any if used with the correct leads and plugs?

Sorry for my ignorance, but if you don't ask...........

Il let you know once i get my car back , having one fitted at the moment

Quote from OutMotoring about it
"Screamin Deamon Ignition Coil Pack. The stock coil puts out 36,000 volts under heavy load, but this one puts out a shocking 40,000 volts under heavy load. The voltage increase is enough that plug gaps need to be opened up to .065 inch. This hotter spark will now travel through more fuel and air making a better burn in the combustion chamber"

a spark is a spark as sparky said

So, no great bhp improvement I regret

Not a case of great bhp improvement it Idles better, better throttle response, smoother boost.

Agreed.

Do NOT open the gap .065. That was tried and wasn't especially succesful.
.045 works fine but keep in mind this requires more work. More work makes the coil run warmer, warmer = won't live as long.
I am NOT implying there is a drastic life span impact. Just explaining the realities of doing this.

I have been running a .042 gap for over a year with no issues. Slightly bigger gap gives you a slightly fatter spark. Fatter spark makes for a better fuel burn.

Edit: Forgot to say I've been running the Screamin' Demon for well over a year.

Just to be thorough, leaving it at the recommended gap isn't a bad thing to do either. MOst come gapped to .036 if I recall correctly.

Bingo.

These things used to make a difference in old points-n-condenser,
carburetted engines, but not on our coil-per-2 plugs, fuel-injected engines.
