I am very curious about higher boost levels. I suspect combustion chamber design including the spark plug location, heat management at the combustion chamber, timing, and AFR all come in to play.

The data points above on pulling the timing back and what it dose to exhaust temps is interesting.

Also, I suspect fattening the AFR's should make the mix less volatile. I wonder what the point of diminishing returns are with this and how much if effects the sensitivity to pre-detonation.

Can we make more power at 11/1 afr with 1.2 boost and the right timing so the mix quickly enough to not burn things up?

What are the limits?

How do people run 20+ pounds like on the Audi.
