I've found this article helpful and have used it as a base material for my nutrition plan. (along with the tokens of wisdom from the trifuel clan.)

Although, this article is more focused on the IM distance, much of the information (if not all) can be applied to the HIM and OLY distances. At some point, however, I think that higher exertion rates in shorter distances might decrease the amount of calories your body can process.

Your question was: What happens if you eat too much? You could have GI issues, you might feel full, you will probably cause blood to flow to your stomach to aid in digestion rather than where it should be... your muscles.
I don't know if I'd even worry about this stuff during a sprint. I probably would shoot one gel down on the bike just because. But as was mentioned in another post, you have approximately 2000 calories stored in your glycogen stores. If you're pushing really hard, you're burning 1000 calories an hour during a sprint. 1000 left over if you can finish in an hour.
On longer races you're obviously going to burn through that 2000 calories quickly... well... except for that you've been conditioning your body to learn how to burn fuel efficiently in which case it will then turn to fat. In your fat stores, I seem to recall there being about 70,000 calories.
Tons of stuff to read... I'm sure most tri books have a section on nutrition. I don't know if you're going to find an entire book dedicated to race nutrition. You're still going to have to dial it in on your own because each person is different.
For starters, use the range above and work from there. Things to consider, too much protein will cause GI issues. Your standard gels are carbs, but there are some that mix in carbs and protein in a 4:1 ratio. It is believed that this mixture is better than just carbs. AccelGel is the one that comes to mind. They also make a drink, Acclerade. I believe Endurox R4 is another with the same ratio. And of course there's Infinit which I believe you can get any way you like. I personally can't survive a long course race without protein. I've tried just gels and fall apart. Some people can do an entire race on gels.
My thoughts seem a little random... hope this helps.

Quoted from other post. I'm really interested in learning more about this idea of how many calories you can process in an hour. In other posts I've seen sites to how much of what types of calories you can post as well.
A few questions: What happens if you eat more than the amount you can process? Do those get packed into fats and stored, or do those get packed into... well, you know...
I definitely learned that I was over eating during sprints after doing my first olympic. Basically, I got stomach cramps eating during sprints, but the same routine during my first Olympic was almost perfect. Do you find you can process more or less per hour if you are racing/ exercising?
Is there a particularly good read on the topic that should be read as the basic primer to this idea?
To tri or not to tri - that's not a question at all!
