Which LRRS fuel is the best bang for your buck?

Hey guys, after 3 years in the NE, I'm finally putting together a bike to start racing again! I see that both U4 and MR12 are not legal when racing at Loudon. So before I send off my bike to the tuner, I need to figure out what I'll be running next year.

So... What makes good power? Or at least which fuel makes the most power in relation to its price tag?

Thanks!

You getting a ss motor done? Have it run off of the pump gas 93 that's at the track.

Sure, a SS or something like that 😉

The have pump 100 octane for 9$ a gallon. It's the cheapest hi-Po stuff per gallon if that's what your looking for.

In short: You can't get any really power building high test oxygenated fuel. The stuff they do have that claims is oxygenated is just ethanol 'boosted'. There is higher octane fuel so you can build with a higher compression ratio / more advance?
