octane is is not everything! the ron number is the limiting factor of deternation and yes tb kit is 13:1 and runs great on pump gas why?

because of the combustion chamber shape! dezmo do limit your self to black and white thinking,always think out side the lines and use the k.i.s.s. method!

and that is most important in engineering! R.J.P.

if anyone is interested? check the explination!

ok

combustion chambers have angles and edges right? well they do, sharp machined edges get hotter than smoothed out hand blended edges(fact).so when the engine is really hot these parts can cause preignition from these hot points! so if you have a good design you can get away with a higher compression ratio before detination,provided your load on the motor is not to excesive(eg,fat ass) so what do you think? is that a good enough explination? i have many years experience building lawn mowers to touring cars and everything in between i have ama,afm#1 winners with my chassie and suspension, so i guess i have a clue on what works, i don't need smoke nor mirrors to convince people on what they need.
