Ignition timing + Cam Phasing

[Civic Type R]

you adjust the distributor. I think Dyno Dave has already covered how this is done in another thread.

people...please correct if i'm wrong okay...i heard what..then i tell what oni...hehe..

it seems to me that you are just regurgitating meaningless crap - why are you doing it?

can you also try to use better syntax?

you are posting very poorly...

i dono much thats why i wanna ask more..

well, you need to try to make more sense with what you are saying and asking...

no offence intended.

[todaek9]

you mean the 6 degrees in/ex advance...?...and the 30-40 degrees advance in ignition timing?...hmm...was saying that's extream...

yes, these are extreme when considered in simple isolation, but might be perfect for a circut racing car tuned with MoTeC or something...

what is your question?!?!?

[todaek9]

i'm just asking does anybody know what degree of cam phasing and what degree of advance ignition timing to match the compression la...

for example, lets say 12.5:1 compression...

[todaek9]

and also...wht does it do...why need too much ignition timing?...why so much cam phasing?...why it must run 12.5:1 compression but not higher?...why is higher compression not suitable for higher advance ignition timing...??...tinkerbell...i think you know it all...answer me if you can...

[tinkerbell]

and also...wht does it do

'timing' is the point of the crankshaft Before Top Dead Centre (BTDC) when the spark plug fires e.g 18 degrees means that the spark plug fires when the crankshaft is 18 degrees before the piston is at top of its compression stroke

...why need too much ignition timing?

so that the combustion can occur earlier to make the most of the available compressed air/fuel mix

...why so much cam phasing?

to keep the valves open correctly to allow the proper air/fuel mix to enter the combustion chamber

...why it must run 12.5:1 compression but not higher?

physics dictates that it is inversly harder to raise the compression ratio the higher you go

...why is higher compression not suitable for higher advance ignition timing

because fuel has a octane level that dictates that it will pre-detonate if compressed too much

...??...tinkerbell...i think you know it all...answer me if you can...

you will find MUCH MORE AVAILABLE information on the internet if you look for it.

once you have half an idea about what you are talking about, then we can have more indepth discussion...

that's it from me here.
