Question Advancing the Timing?

Can someone please explain why people advance the timing on their car?
I know what it is physically, but what benefits are there, and why?
Is it worth it? Is it worth while on my EL XR6 as I always run premium.

Thanks!

Re: Advancing the Timing?

Advancing cam timing moves the peak power lower to lower RPM. Retarding the cam moves the peak power higher. Basically, you can get a higher reading on the dyno by retarding your cam, but you will loose low and and mid range power. Advancing your cam gives you more mid range and low end at the expense of high end power.

I wouldnt bother doing it unless you have changed cams and are trying to find its optimal position. Factory cams are set up well by ford, and although you might get a better dyno reading by playing with cam timing, your car wont be any faster.

Re: Advancing the Timing?

Did you mean ignition timing, or cam timing?

Re: Advancing the Timing?

Sorry, ignore that - I was sure I was 'cam' in there somewhere.

Regarding ignition timing. If you run on premium you can advance timing for a bit more kick.

Re: Advancing the Timing?

you will get slightly better economy and a bit more power mainly noticable in low to mid range as i have found.
its a worthwhile i reckon, as it doesnt cost a cent aswell.

Re: Advancing the Timing?

Ok so basically, I just hook up the timing light in diagnostic mode?
Turn the dizzy so that the timing mark is....umm...where to I move the timing mark to, to advance the timing a few degrees? And how far do I go?

Re: Advancing the Timing?

i just did it by looseing off the dizzy and turning it.
to do this turn it opposite in the direction of the rotation of the rotor (clockwise 4 this model), opposite being anti-clockwise.

i didnt turn it by much at all. if you have done timing before u will have an idea how much to turn it, i prob turned it by 1-2mm. took it 4 a spin and it didnt ping so i left it.

i will prob giv it a bit more one day soon and see what happens.

Re: Advancing the Timing?

While on the topic... in my EB, I can only turn the dizzy so far advanced then the TFI module butts up against the ISC/TPS sensors. I cant advance it anymore yet at this position, there is no pinging. Is this normal or is my dissy in wrong?

Re: Advancing the Timing?

sounds like the dizzy is in the wrong posi to me.

also, even though if u advance the dizzy right to the point before it pings, u can still not be in the optmium position. make sure there is a registrar on the seat of the pants' o ometer.........

has it the dizzy ever been pulled out b4? or was it like that b4 u bought it?
