110 Octane...150 shot and stock motor?

110 Octane...150 shot and stock motor?
Kind of a newb question but after looking through most of the threads on here, it doesnt seem to be covered..
I recently put a NOS plate kit on my 99 T/A ...and was curious if there was necessarrily any ADVANTAGES/DISADVANTAGES to running 104 up to 110 octane in the car...or maybe throwing a few gallons in the tank when it gets low to boost up the shitty 91 octane with up to 10 or 15% ethanol they have around here. Thanks.

I always put a few gallons on the no lead race fuel at the track when running nitrous as kind of an insurance policy in case the 93 octane I get at the pump is a little funky or something. The total volume of race gas is never more than 30-40% of total fuel in the car. I have also used C16 leaded race gas as well many times, just keep the ratio heavier towards pump gas.
I also pull 5deg. timing of my n/a tune as well.

Many run a separate fuel cell dedicated for the nitrous for that reason, spraying a higher octane in with the nitrous only when needed to prevent detonation, not to mention cheaper on the fuel since you really use less.
I cheat, there is a small air field next to my house and their aviation fuel storage takes debit cards, so i always run that av gas, 100 octane low lead and it works perfect. It is blue for some reason, probably means taxed or something like that, smells nothing like gasoline.

Definately the best option with a designated fuel cell. Running on race in your tank is a little scary with these newer cars. Be careful with it, LOTS of heat.

No telling, on my end, plugs never have a issue, several friends run it and never had a problem, maybe N/A it could be a issue on high compression and then a N2O shot? Got to be safer than pump gas i imagine, wonder why it would burn hotter if it has a 100 octane rating? Doesnt make sense.

I had a friend that ran high 10s with a dedicated fuel system and a 200 shot on a bone stock bottom end LS1 with 243 heads. Tunning is going to be key but there is no question that the dedicated race fuel has a lot of advantages and for 500-800 bucks its cheap insurance.

Any of you guys from N2O outlet, HSW, NX or any other experts care to comment on running 93 pump in the tank and using something like a c16 in the standalone.
I've heard and seen some pics of different flame front travel of the different fuels. Is this a real issue or just heresay?

if you think about it, the more BTU's of any type of fuel that you can successfully burn in the combustion chamber, the more power you will make. so the "it burns hot" argument is a little skewed, in my mind, but i am far from an expert or a chemist or a physicist or an engineer. i'm just a mechanic.
edit: wikipedia and google make us all instant experts nowadays and after a bit of reading, that avgas 100LL (low lead) is some good stuff, as long as you don't have oxygen sensors or a catalytic converter.
and the "colliding flame fronts" argument is old hearsay, IMHO.
