and finally our beloved china girl
fine print: these aren't my photos. I just ripped them off facebook. I'd have never pointed my ports towards the exhaust like that
i could be wrong, but thats the intake port, innit? looks like its been carved out for reeds and has one of them piston port bypass thingys.
or youre criticising how the lower edges are near in line with each other and just a lil too close to the exhaust for my liking either?
i woulda left a lot of that exhaust side lip there for angle control. remove it empirically... like everything else.
i think this guy followed the "do it all at once" approach which NEVER works unless you already KNOW it does...
hence why i still think a smoke box is the best way of analyzing ports. without seeing whats going on in there,at speed, its all just guesswork
you can visualise it, you can picture it in your head but often reality bites you on the rear end because there are so many unsolved parts in the equation. do i
really know what the air speed through the port is at 10 degrees after opening? i doubt ANYONE does
and how dense it is, so whats the speed of sound through it, at what point does it stall into an airlock, etc...
ive mentioned it before...i seriously HATE tearing an engine down, rebuilding it, reinstalling it, only to know INSTANTLY youve made a whoopsie... many a whoopsie
wrong thread :wacko:
