Ya I did some reading about toluene. I haven't even tried to find it. I assumed it was like all good things, banned by the Ca. Air Resources Board . I'd certainly give a try if it's around and it saves a few $. Suposed to be paint thinner of some sort (no?).
Read a couple of hard-core articles on it. One was a bit breathless about how great it was, still rang like good science though. But then another suggested that, in short, it hits a point of diminishing returns despite the octane. Something about the speed of the heat dissipation or something...pretty molecular.
As for shooting for 100 oct., I've run it that way, wasn't hypervigilant but, just by the seat of my pants, I didn't notice a big change. As I understand it, with a stock engine anyway, you buy yourself exactly 0 if you go over the manufacturers recommendation. Obviously forced induction changes all that but by how much I wonder.
