I've been running 94oct from the pump and I've ran 18psi of boost(not daily) every now and then for the past 2 years. For the track, what kind of race gas is good for a bpu+supra. Is higher the octane the better? or is there a point where it's too much octane won't help my car at all? Also, depending on what race gas I use, what's a safe level of boost for race gas? Thank you.
