Does ab work outs effect your velocity on your fastball? Also I don’t really have a ab work out program I just do 250 crunches every night and 100 twists. So what should I be doing?
Well, having a strong core can help a pitcher develop more velocity. I don’t do any ab workouts. I just focus on compound lifts like sumo deads and squats. Also, I do sprints, etc… Generally, with a solid program, and good nutrition habits, I see no reason to do an ab workout every night.
But, if you would like to vary your routine up, and maybe do something different, you could do a medicine ball workout specifically targeting certain pitching motions.
In the off season, I add front squats to my routine, and perform that on back day. Trust me, after doing these, there’s no reason to waste time on crunches. But that’s just my opinion, I’m sure others will be able to help you out on this.

He also has a program that you can buy.
You might try varying the crunches that you do such as including side crunches and cross leg crunches, reverse crunches, etc.
