I was talking to a V8 engine builder tonight and he swore by these products.

anyone ever try them?

Fuel additives and race gas.

They list an unleaded r+m/2 of 108 octane. That's the highest unleaded I've seen. (VP 109 is really a r+m/2 of 105)

He also said v8 guys are adding a gallon of their Nitro line to boost octane. Anyone know about these or try them?

And this as an oil additive; is it snake oil?
