Thats where your raped ape got its extra power, from
water in the chambers - enough to perhaps increase CR
(effectively) and reduce pinging for the short period of
time,

I've noticed this on a ford escort when I blew a gasket between
chambers 2 and 3 - bit more power (!) for a little while then
kampumpf :(

Do you normally run a wet manifold ?
