If villain has been minraising often then I think its fine to call here. Have you seen him showdown any of the minraises?

I like the turn push because you also have the flush draw. So you have outs if he was slowplaying.

I don't think a pair of 8s calls here and I don't think a pair of Queens checks behind on the flop then calls a turn push with the Ace out ther, so I'm really only afraid of him slowplaying a pair of Aces or better. And even then your drawing to the nuts.
