i run 24 degrees at wot with 93 oct, and if i was to run 90 what
does that do to the afrs and timing thanks.

zrater

not much change then just watch for knock, and there is none at 24, does the
car loose power running 90 or just slams in and out of low and high octane tables.. thanks

faster on 90 'or 91, but i dont no !! huh

If you have a car and it is running 24 degrees of timing and you are using 100 octane fuel and it makes 450 hp.

You take that same everything and put in 92 octane fuel and it is still running 24 degrees of timing and no knock then it will still make 450hp.

You take that same everything and put in 90 octane fuel and it is still running 24 degrees of timing and no knock then it will still make 450hp.



The reason for running higher octane is to allow you to force more timing into the engine to make more power. BUT if it isnt maxed out then it wouldnt make a difference if it is able to run the same amount on a lower octane.

If you have a car and it is running 28 degrees of timing now that you are using 100 octane fuel and it now makes 466 hp.
