As mentioned, try contacting your local race track or a speed shop. If no luck there, try searching Sunoco and VP race fuels online to see who is a distributor in your area. You may want to also post this thread in the regional forums if all that comes up empty.

See the deal is, i'm running a 100 shot on 91, its been tuned by Ion for that, its doing fine on the 100 shot & 91, i was wanting to try some 125 pills, but i'm not pulling anymore timing, so i wanted to play it safe & run some race fuel mix, i did talk with Ion yest., he said the tune will still be good on a 125 shot, but a mix would'nt hurt, if i new of any sure fire octane boosters out there, i would just do that.

Simple way around the O2's: turn them all off and tune the car in open loop. Now all the O2's do absolutely nothing and you can run any fuel you want. Punch the cats out if you have them too as the leaded race fuel will burn them up in about an hour. Unleaded race fuel will do it too, just takes a little longer.
Get the car redone in open loop, take all the O2's out, put some bungs in their place, run whatever you want for fuel. Then put your o2's back in when you have to get emmissions tested and just swap the tune over to the tune with the O2's still in.
I went down this path, trying to run unleaded 105 octane race fuel with my race motor initially. As soon as I put the first tank of 100 octane leaded gas in it was night and day ran 10 times better, turned the timing up a little and put 116 in and whamo went .2 and 3 mph faster from no other change.
Ditch the o2's completely, gut the cats if you have them, put some leaded race gas in and let it eat. You'll wonder why you didn't do it sooner.

I think you may have to wait and get your gas out at Rogersville when you get to the track. I don't know of anywhere else off hand that you can go get it at the moment.. but you could try getting ahold of someone at OIR and ask them if you can get some fuel ahead of time at the track or if their vendor has another pump location somewhere around the area.
edit.. this is assuming they still keep the unleaded up there.. dunno why they wouldn't. Then again, around here it wouldn't surprise me if they didn't. Either way the guys at OIR should know where you can get some. If THAT doesn't turn up anything, give a search for VP or Sunoco vendors as suggested, or give the fella's over at 417motorsports a call they can probably tell you what's what in the area too.

Yup. You need a tuner that knows what they're doing, but I assume you have that covered. You'll have to retune the car for WOT a/f, and probably make some adjustments for the part throttle, but not a big deal.
Car will stay tuned beter without the o2's messing with it too, that I guarintee 100%

There's always zylene. It's in premium unleaded anyway you just up its percentage.
Zylene is 118 octane , I used to blend it on my 3800sc car to run smaller pulleys and more timing at the track .
Learned it from the grand national guys 5parts premium to 1 part zylene from home depot etc.... If your going to use a lot they say you can buy 55 gallon drums from paint supply houses for about the same price per gallon as gas but I only did it on occasion. Google it you will get plenty of info
