RE: [Chevelle-List] Advancing Timing

[Wayne]

Keith The largest reason for more power being developed by advancing the timing is that the air / fuel mixture gets a more time for a complete burn. The more mix mix that lights up in the combustion chamber the more energy is produced, thus the more power. Advancing the timing too far has a reversed effect though and raises the chances for spark knock or detonation which can be harmful to the engine. This also adds produces more heat inside the combustion chamber and at higher speeds if advanced too far can produce some serious problems if advanced too much. Hope this helps explain this a little for you.   Wayne 66 SS   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Keith Cooper Sent: Saturday, June 08, 2002 10:26 PM To: [EMAIL PROTECTED] Subject: [Chevelle-List] Advancing Timing I am just sitting here thinking (very dangerous thing to be doing) about why advancing the timing makes more power. If you go from 4,6,8 degrees before TDC to 10,12,14 degrees on the timing, why this makes more power. This means that you fire the plug 10+ before the piston reaches TDC. The piston is still moving up when you decide to fire the plug early. When you fire the plug  early by advancing the timing, the piston is still trying to move upwards, but you have fired the plug and the force should then try to move the piston down, but the piston must still pass TDC before it can be forced down.  Why is that?. I am confused. I know that advancing the timing makes more power, but WHY. Your firing early Just wondering Keith Cooper [EMAIL PROTECTED]   See my Chevelle: http://home.mindspring.com/~keithc/index.html
