Depends on the setup. Most guys say they run best with a blend, anywhere from 30/70 meth/water to 60/40 meth water… The best thing ive seen, to best utilize race gas on the street, is the system they call “octane on demand” where they have basically 2 fuel systems, one for race gas and one for pump gas, and when your tooling around town youll run off the pump gas, and only when you go to wot or get into boost will you switch from the pump gas to the race gas. Complex but pretty well thought out, race gas isnt cheap these days
That sounds like really great setup. Infact you could be running 87 and have it switch to 93 or 100 when you hit like 3-5 psi. Overtime, could be cost effective.
