Less gap means a less powerful spark, but it is also less affected by higher pressure inside the cylinder. As far as I know. So it might be less powerful but it's the lesser of two evils when you have misfires.

All this gap talk and all I'm thinking of is this:

fuuuuuarrrrrrr

feeling better nao borci?

feeling better nao borci?

Not really, she still contacts me every few days, whether it be about something useless like how she saw my cousin at netball, or how thursday night she had a bit of a go at me thinking it was me that logged into her facebook, and how i've f**ked her right off and don't care about her anymore. I gave her nothing back... blunt and honest, tried not to show any feeling.

I'm going out tonight, theres another girl now that I'm NOT interested in in the slightest, but shes becoming attached and it's doing my head in lol. I dunno man, I still have this little hope inside of me that me and the ex will get together again sometime soon in future, and I think it will happen, but I need to let it go.

This was what I was getting at, clearly he has less power with a misfiring car, than with .8mm gaps on his spark plugs.

But now I'm curious with the whole less gap= less power I didn't think it would really make a difference, once the shit combusts it would explode anyway wouldn't it?

[Sunkist]

Lol and as Leigh's picture. Less gap, more fun

Ford forum sponsor has special $2000 for:

FG 6 Piston front kit @ $2000
Brembo 355mm slotted rotors
Brembo 6 piston caliper
Brembo brake pads
Goodridge braided lines
Custom alloy brackets

Tempting! Perhaps then I might do some trackdays..

Thoughts about Brembo rotors? how to they compare to DBA?

well, try not to lead the other girl on too.

unless she's hot, then, you know, by all means, carry on.

Ain't even impressed LOL

The bigger the spark, the faster the compressed mixture burns = more power...as far as I know. I think it's one of the reasons ethanol makes more power, because it burns faster than petrol?

[Sunkist]

Ethanol burns slower..

But wouldn't the same amount of current be traveling through the gap? I mean I could understand how a higher voltage would create a bigger spark, but not just stretching the distAnce between the two elements

[xALmoN]

stretching the distance means a hotter higher spark. increased ionisation of the gases means also a more complete burn, a smaller gap will mean a smaller spark, and thus, less complete burns?

[Miguelone]

So smaller spark would then require more energy to equal the spark produced by the larger gap?

[Count Grantleyish]

Somebody's a bright spark huh?

[emts]

thanks f**k the working week finally over.

beers time

[xALmoN]

more like, the hotter and bigger spark is due to the larger gap, thus larger arc and ionisation of gases.

but i would assume a bigger voltage is needed to be able to form the arc across the gap, thus when coilpacks are worn, or ignition system is bad, bigger gapped plugs would show moar misfire.

Kebabs

[xALmoN]

where?

On looking it up again, ethanol does burn faster. It's what creates more torque without even touching timing - more heat (not hotter, just more of it) created sooner and therefore spending more time exerting force on the piston than petrol.

If my mind is in the right state, a similar principle applies to advancing ignition timing (be it with petrol or ethanol) to create more torque/power: you're firing the cylinder closer to the start of the "power" stroke, so the heat can push on the piston for longer.

As for spark gap: the bigger the gap, the longer the arc/spark = the more spark there is to ignite mixture = the faster it ignites and burns = the more power it makes. Pretty sure that's how it works. This efficiency is, however, negated when your cylinder can't ignite at all...which is Pat's current (pun) problem. The rule of thumb is that you should run the largest gap that doesn't offer misfires.
