Where to get super high octane race gas??

[E911me@aol.com]

I know of the 76 station near Almaden with 100, but I've heard near Fremont or 
Newark there is some gas supplier with a couple different race gas grades?

I'm trying to find a source of 110ish octane unleaded race gas for a friend who 
is dynoing a big turbo car. 

Any leads are appreciated.

Thanks,

Salah
