Interesting.... there is not much combustion mixture in there... Does it do something to slow, or mess up the combustion process? Or tend to detontate and thus you have to limit timing? Or what??
And would you really need to take care about this on, say, a 400 HP SBM street engine, that saw little or no strip time?
(Sorry OP, but this off-tangent question is SOP for FABO LOL)
