  • PROOF that 93 octane produces more HP then 87

    to anybody that argued with me about 93 not producing more HP then 87... [img]graemlins/slap.gif[/img]

    look at this dyno chart and tell me that 93 octane doesn't produce more horsepower then 87

    93 allows more timing.

      That's not because of the fuel, it's because of the timing advance in the HPP. Like blacksport said, the higher octane fuel allows for more timing advance, but the fuel itself doesn't make any more power. Changing the tune adds power, changing the fuel doesn't (assuming the car is running properly).

      That's also propaganda that has no truth in real life.

        so 93 octane allows the opportunity for more horsepower but you are saying just running a car on 93 octane won't increase the horspower vs. running 87?

        I can't wait until next season.. I know there is a difference in my car between 87 and 93

          Yes, that is correct. Assuming your car is running like it should, you will not get a single extra horsepower from running high octane fuel.

          If your car has problems, it may be experiencing detonation which would cause a timing retard. If so, high octane fuel may alleviate the KR and increase power slightly, but it wouldn't be any more power than a normal car on 87.

          Going to move this to General Tech...
