quench vs no quench?

Like most of you I've been watching this and been waiting for someone to address the quench
VS no quench question.
I am no engine or head guru but it was always my understanding that using a quench
style combustion chamber could be used to speed up the burn of the fuel mixture.
This was supposed to allow for more compression without detonation for a particular
octane. The cooler the intake charge the better. I do know the engine should be built
around this design. All high performance engines should be well planned.
I don't think the question is if it is a better design but more how much better for your particular engine.
I wish I had one built using the quench chamber to give you this answer but I don't.
The next engine I build will. Hope someone who has one up and running can give all
of us their take.
