The question was more for the original poster.

You need to tune for the higher octane. My coworker's NA B20/VTEC is tuned for Q16. He made just short of 230whp on our dyno.

Seriously....otherwise more octane isnt gonna do much if anything

Higher octane is just to prevent knock with raised compression/advanced ignition timing...if you dont raise the comp or get crazy with the timing you really wont need high octane

If you do E85 is cheaper than race gas and is 101-102 octane or so....youll need to use more of it to make the same power but its much cheaper than race gas

I used 100 octane on certain races & usually shave 1-2 seconds in times. I best way to feel optimo gains is by using all the lower octane fuel possible & than add 2 gallons of higher octane. Also make sure you use unlead NOT leaded fuel. BTW that's referring to my K20, I haven't tried it on my LS. < maybe this weekend, since I'm running the DC4 >

do you have the tune to run that high of an octane?

if you do unless youre hitting the track then you are stupid for wasting that kind of money just to "rip shit up"

well 80% of the time i put in sunoco 94 octane, decent gain over when i first got the car and used 87 i want to try race gas in the b16a i-h-e see if it opens it up a bit more.

since its not tuned for anything all this high octane is doing is prevent knock ? 8500rpm on 105 octane would cause less wear apposed to 91 ?

It will help reduce detonation, but if you don't have an issue with it, it won't change anything besides losing HP. And gas doesn't prevent wear, oil does.
