101 Octane????
This morning as I was get a Lottery ticket (need to will that 6 million 
) at a local Mobil gas station I saw then installing a pump for 101 octane! 
That many people buy 101 octane??
I was wondering if 101 octane does anything to stock motor as far as horse power and or if it help the performance of the motor as well? Even with HP parts, how much horse power can you get from gas??

There is no sense in putting in 101 octane unless your engine requires it. It won't make any more power. Now if your engine requires something more than 101 and you put 101 in, not only can it damage/destroy your engine, you will lose power.

A friend of mine suggested that I run higher octane before I go out wheeling....something about it resulting in a less chance of detonation.
Dunno if its true or not, dont flame me, its just what I've heard.

Best website for finding out this kind of info. I've learned sooo much there.

Look at it like buying a rain coat.
Your going out in a light rain storm(regular car engine). All you need is a cheap $2 rain coat(cheap pump gas). You could spend $400 on a rain coat(high octane fuel), but it would do the exact same thing. Now let's say you are going out in a monsoon(high performance engine). That $2 coat(cheap pump gas) isn't going to do much, but the $400 one (high octane fuel) will (for the most part) because it's designed for it.

The 101 octane fuel will mostly be used by domestics/imports with upgraded turbos/SC's etc.
For example, when I had my Audi A4, I had APR's Stage 3 turbo upgrade and the ECU was re-programmed for different octane levels. My ECU had 91, 93, 100, and 104 that I could switch from. Basically, the higher octane, the more advanced the timing was.
And you could definately feel the changes between octane, I got about 40+ more horses when running 100 compared to 91. It's amazing what an engine can do when prgrammed to take advantage of the extra octane.
But like what oly884 said, there's no reason to use it unless your car can take advantage of it. Ours can't.

In theory, if your S-AFC II allows mutiple spark and fuel maps, the 101 would be beneficial. You could run more NOS w/ less chance of detonation... 101 isn't inherently BAD for a motor... you can run 93 in a car designed for 87 just like you can run 101 in a car designed for 93.
Where it's really helpful is in high compression motors, either NA or forced induction.

To take advantage of higher octane timing, etc. really needs to be advanced along with fuel curves and that's where the gains come from.
But it couldn't hurt to have higher octane gas in the tank when your going to spray to prevent running lean and damaging the engine.
