Timing - Effects?

[1Greg]

If the timing was retarded a few degrees, 2 or 3 or 5, BELOW the stock setting, what would be the effect on an rb20 (with fmic, 320hp turbo etc).

What would the effect on the cars peak power, power curve and driveability be?

Hey I know this is off topic....but what is the standard timing setting on a RB20?

Usually you will lose torque wherever it is retarted. Which obviously has an effect on power output as well.

The ignition timing needs to be advanced to the point of best mean torque or peak combustion pressures in the cylinders without detonation.

Also with retarted timing, you get worse fuel consumption.

I would only retard the static timing if your car was pinging because of a larger turbo or something. Otherwise set it to standard.

15deg btdc @ 700rpm is standard timing on RB20

Retard the timing and your EGT goes up.

Not good for turbo that has a ceramic exh. wheel.

So if it was set to say, 12 degrees, is there any chance that that would end up in a very very lean torque curve, with a very linear power curve, yet resulting in still a reasonable about of top end?
