[6pack] [TR] Compression boost

[Kendall Larsen]

This topic reminds me of something that Ibve never quite understood about
pre-detonation pinging and knocking.
B 
We talk about smoothing out combustion
chamber hot spots, higher octane gas, and spark advance after boosting the
compression ratio. But I donbt understand how spark advance plays into it.
Isnbt the pre-detonation a result of the air/fuel charge igniting before the
spark anyway? 
B 
Anyone want to layout what the factors are in all their
technical glory?
