Highest octane we can run without a tune

[Carl Sagan]

There is only one way to find out...... time to dyno the bronco on 100 octane to see if there is a benefit over 93 octane! My guess is it will put more power down with 100 octane.

Wait, Gas or Diesel???

If you are talking 300 Ft/lbs per liter on gas, well, I can safely say: nope, not even close. That would be savage.

If we are talking diesel, maybe, I would have to find and look at some of my old dyno sheets. I still don't think that I managed that, maybe more on the order of 200-250 ft/lbs per liter.

Now, blown top fuel would get you there. I have friends who have done that, but that gets more expensive than I can afford.

Oh definitely diesel
