Basic implied odds checkup

[nomathsdoh]

Just need to make sure that the following implied odds calculation is correct if somebody would care to help.

150 in the pot on the flop. I have a flush draw villain has a set. 500 remain in our stacks. Villain bets 100. My implied odds of calling this bet assuming I can get it in 100% of the time on any turn are:

(if I hit my 8 outer on the turn I will win 77% of the time)

.77(150 + 500) - .23(500) = 385.5
making my implied odds 385.5 to 100 or 3.85 to 1.

Odds of hitting the 8 outer are 4.87 to 1

So this would be a losing call.

Is the above correct? Thanks in advance to anybody who is willing to do this one.
