80 pounds is a lot for 3 months. Is it doable? My instinct says no; you need more time.
Now perhaps your 235 is an easy max, with poor form and sloppy technique. In that case, fixing form and technique and learning to push yourself, you might put 20-30 lbs in a week. Of course your still looking at 50 lbs in 3 months, but that's a lot more reasonable.
Look in the archives. Christian Thibedeau has a bench specialization program. Also, look into Westside. It's hard to offer advice without knowing where you came from and how you got where you are now.
What have you been doing? Are you stuck right now? How long have you been training? Etc, etc.
