Will it run cooler on race fuel?

After a lot of searching to no avail, I'm going to risk asking a stupid question *flame suit on*
Cliff notes: Will running 100 octane unleaded without changing anything else make a turbo Miata run cooler or improve reliability? Yes, I know it wont make more power unless I tune for it, and I'm not going to.
Long version: I have a 1.8 running 8psi w/ a gt28RS and MS that I raced in hill climbs, small circuit time trails, and autox's last year. It had some overheating issues on the small circuit time trails, which I think I've fixed with a bigger radiator and ducting.
I'm starting this year with a two day "big" circuit time trail and I'm concerned about heat and reliability. A friend recommended running race fuel because the car would run cooler. I've never heard of this before and always assumed race fuel was useless unless you tuned for it... so is he right? Are there any reliability or heat management benefits to running higher octane without tuning for it? Would it lower EGT's?
