I believe it's a tad lower than high octane race fuels, but the benefit of cooling the intake charge so much outweighs the small loss in octane.
Anecdote: My friend has a Mazdaspeed3 with a trunk meth setup, and under full boost and load, his intake temps, measured at the manifold, are around 70-75 degrees F. And this is in South Florida during the past summer.
