Re: Does It Hurt a Motor to Retard the Timing to Run in a Slower ET Cl
Doesn't seem like I could go much lower on the shift point - its already at 5,000 and isn't a high RPM motor. Suppose I could go to 4,000 and see the difference. I've talked to a guy with a 598 who tried to slow down his son's camaro to run 11.70 for the high school class by limiting throttle travel, but couldn't do it consistently.
I have a timing retard knob for the 6AL box, so thats why I was leaning towards that, as it can be changed from the drivers seat, even if still in - in both quicker and slower classes. Part of the reason for the advanced timing is that the Air Density is usually 9-10000 ft, though a little better in the fall.
It wouldn't seem that anything mechancial would be hurt by retarding the timing, as long as done consistently. Wouldn't have to raise the hood, just reach for the dial-in for the window.
