Wasn't this used by Smokey Yunick back in stock car racing, in days of yore? Definitely not new.

Yep - late forties or early 50s. He tried (probably one out of a thousand things he tried as a porting 'medium') pumping cement through them.

Back then, factory inlets were (usually) so restrictive that almost anything would make an improvement. Nobody uses this technique these days.

There's some talk that it automatically ports the best flowing tunnel all by itself. Complete bullshit - just look at how rivers snake all over the place, cutting more out of some places than others. Yes the water ends up where it needs to go, but far less efficiently that if the 'river' wear designed by an engineer.

Most interesting is how many people (and i didn't go to the link) have claimed to have made a 'breakthrough' with it 50 odd years after it was first tried.

lol you should have clicked the link the breakthrough is porting without having to disassemble the engine at all..

Pffft .... 'sif air is smart enough to know where it wants to go.

perhaps more the point is that the abrasive medie has different characteristics to the 'air' and thus would react differently to changes in direction etc. Not really a controlled method!
