I believe most everything is a 87 oct. Normal the only thing that would force you to raise the octane in your fuel would be if you raised the compression ratios. After market parts such as a new wiring system, intercoolers, and anything not dealing with the engine itself will not require an octane boost.

Octane is a level of rating fuel. It measure how slow it burns, but more importantly what tempature it will pre-fire (explode due to heat and not spark). When you have a high compression engine like a stroker the fuel will heat up more then normal at the top of the compression stroke. If the doesn't have the needed octane it will pre-fire and you get bad engine knock.

So on less you are changing the compression, which I am not sure if supercharges and turbo do or not, you should be fine with the stock 87 min.

i wouldnt run anything but the highest octane if i were you. if you drive your car alot it becomes a bit pricy but it is def. worth it. im pretty sure a stock stang calls for 87 min. atleast thats what mine calls for, but i run 93 anyways.

I'm not sure what benefit you are getting from running a higher octane than needed....in fact I was told by Ford not too, except in my 67 which has a Ford Racing crate motor that calls for it. Can someone explain to me why you would run higher than 87 in a factory spec engine? thanks
