Wouldn't touch it with a very large pole.
I bet you need more octane rating to run the stuff in a performance engine. Even though they say it has less nucleate bubble formation, the lower thermal properties will all but negate any benefits from this directly. In fact, I bet it runs hotter, especially in the cylinder head, which is where it really matters.
Good luck getting a car on track with this stuff in the block also. It's prohibited from most race tracks becuase it's flammable. Not something I wish to have flashing around my engine waiting to spew out at at or above it's documented flash point.
Large pole I tell you!!
