Glad you made this thread as I was thinking the same thing.

No problem man,now that i dont have cats anymore i am really thinking going this route for when i go to the track.

It's a DOHC high compression v8, any octane will result in more power. Fortunately you won't need to upgrade your injectors with higher octane fuel. However, I wouldn't run leaded.

Why? With no cat, you should be safe to run leaded.

I would think benefits would be minimal. Due to being naturally aspirated. Gains won't be justifiable vs a turbo car where you would gain 20+ whp.

Anyone have any graphs?

Because this is my daily car. Leaded fuels not only affect the cats but also affect the o2 sensors as well. There are other fuel alternatives that are unleaded and oxygenated that will still work very well.

Paper fuel filters and leaded fuel don't like each other

Also its not recommended to run that high of octane fuel having cats,even with unleaded.
