CR and pump gas question

I'd like to read that article. It goes counter to everything I've seen.

I should have also mentioned fuel in my above comments, and booster design. All those things have a much greater affect on detonation resistance than does head materiel.
I'll see if I can find it again.... I posted a link to it in another SBM thread about 4-5 weeks back. I was intrigued by the outcome, and was not sure it was 100% but IMHO it showed something worth pondering over. The slowed combustion process was what caught my eye.

What do mean by 'booster'? The auxiliary venturi? That word is not clicking in for me.....
