Quote: I have heard lots of people having problem with porosity from foundry or foundries down in the LA area. I have friends that race fast VW’s 8-7 second air cooled deals and their parts are having the same problems with porosity (the foundry).
But aren't air cooled motors supposed to be porous?
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
