    Unless you are running a very high compression ratio, no.

    High octane fuel is not more explosive.....it's actually harder to ignite & burns slower than a regular grade fuel.

    You don't have enough compression to be running it, careful of the leaded stuff.

    I always run the sunoco 100 unleaded. You can run higher timing without knock.
    Of coarse, I'm 14:1 CR now, but I ran it in the stock bottom end, 150 dry shot, at 27 degree's timing, without knock...
