Limit o8 - Call flop raise here?

[anatta]

4-8 live game. I am in MP and limp behind UTG with

Ac 5c Kh Th. This is a good game with many players seeing the flop with bad hands and going too far. I am new at 0-8. We see the flop 5 way.

Flop Qs Js 5d. So I have a 13 out str8 draw (is this a so-called "wrap"?), but 4 are tainted by spades.

BB bets and SB calls, and UTG raises. Its on me. I am getting about 4:1 current, and it could get re-raised. If I hit on turn, it appears that 19 out of 44 unseen cards (43% or so) make a flush or full house.

This looks like a call since I can miss on the turn, but if it doesn't pair or spade, I still have 9 outs to the scoop (if I don't chop). Oh, I just noticed that my Ace outs aren't so good...
