You will get nothing out of it stock. The whole point in running race gas, torco, E85, Meth, ect is to increase octane and prevent knock. In doing so you can tune for more boost, fuel, and timing to get more power.

Adding more octane to a car that's stock tuned for 93 octane will net you no more power than 93 octane.
