Okay. back on subject.
lets chat piston some more.
Im thinking a top port like this, width of the rear boost.
and some skirt mods.
as I dont know if the skirts are tough enough for 3 holes.
will look into it more when there is a piston in my hand.
Once you start carving up your new/used piston it would be nice to see where a top port like this is with relation to the transfers. Does it extend the intake duration beyond when the transfers cover back up?
should be easy to see with my sweet half Jug that blaster sent me.
and the reason I want to add a port like that, is I believe the benefit of the S cut (big port in center) isnt more duration, but picking up trapped gass'es under the piston.
a higher up port liek the one I pictured would manage this, without messing with flow propertys of the flor and boost port.
as with those. we have same duration as a windowed piston... right............... dont think the skirt closes off those floor ports. Ill have to go look (memory isnt workign right now)
but Id like to add 2 more holes like the ones discussed earlyer, only smaller.
not sure if the pistons are stong enough for 3 holes...
