There are 8 cards that make your straight and 39 that don't.
Your odds of making the straight are 39:8 or 4.875 : 1, or about 1 time out of 6 with one card to come.
You have 2 cards to come. So the probability of making the straight by the river is
1-(39/47*38/46) = 0.3145

or 2.18 : 1 against.
So you will make your straight almost 1 in every 3 times.

we'll assume you raise every time there are 4 people in the pot and call when there are 3 or less (This, I believe is optimal when comparing to pot odds)

So in the above example you lose 3BB 2.18 times and win 10BB once for a total profit of 6.54 BBs.

There are a lot more things to consider though, most imporatantly Whether your raise will knock out potential callers. This is a play you only make in late position with multiple callers in the pot.
You also need to take into account whether you are drawing to the nuts. if there is also a pair and a flush draw on the flop, It might be right to fold. Or you could be drawing to the small end of the straight and be beat by a larger straight.
