it is worth it, if your set up for it. my old man (Best) has a collection of "octain booster". he used to run it in a turbo mustang he built awhile back. iv always eyeballed the stuff wondering if it would help me in makin hp with the blasty.
is "octain booster" what people repher as race fuel??????? i know alcohal is a forum of race fuel aswell but were not talking about that ??
aswell from what i have learned a big use of higher ocatin is to avoid spark knock when running higher compression at higher rpms.
the question is how high in compression can we go with these motors??
