Any advantages to 110?

Any advantages to 110? A Sunoco just finished up the road from me and are offering the 5 gallon pales of race gas. I know people love e85 and spraying methanol but is there any advantages with 106-110 octane? If this has been asked, just point me towards the thread. I used Search and found nothing.

The 110 will have excellent detonation resistance and will allow you to run optimum timing. Also, you won't have to overbuild your fuel system by 30% like you would with E85 or install a nice alky kit to spray meth. The only downside is the 110 will be presumably more expensive than E85 or meth. Not a big deal if you will only want it for track duty but for DD use E85/meth would be more cost effective.

I knew that I could add more timing running it. I bought a pale and it was like 60$, I bought had a stroke. But, methanol or e85 are non existent here unless you want to drive 1.5 hour one way for it. What would be a decent mixture? 5 gallons 93/ 1 gallon 110?

Yeah that is a pretty penny. The 5:1 mixture will only net 96 octane. The optimum mixture will be whatever nets max power on your combo without knocking. Knowing your static/dynamic compression ratios will allow for an estimate but plug reading/dyno tuning will be the only way to know for sure. At that price you may be a candidate for a nice meth kit which is about 10 pails worth of 110 in cost.

In theory some of the race fuels if oxygenated should yield more power simply through being a better fuel even if the engine isnt knock limited.
If it also allows more optimal timing because the setup was knock limited then clearly that's where the big gains would lie.

That assumes he is already at a level where he is knock limited. His build and level of tune may not be though ?
