Sorry, but your totally wrong..
if you run 87 octane on a race motor that is 12:1 compression, it's gonna rattle into peices and burn holes in the pistions from so much detonation... this is because the 87 octane is more unstable at higher cylinder temps ( it is more prone to ignite from heat and compression, rather than spark ).. octane does not add more " explosive components ", it lowers the tendency to ignite from heat and compression... really a 12:1 engine will need around 110 octane
of course if you built race cars, you would know that... I'v got a few years experience in hotrodding, built a hot turbocharged falcon 6, among other things.. I don't claim to be an expert, but I do know I'm right
