Anyone running race gas?

[RedB5S4]

I had Daz write me a 102 octane file and I've been contemplating the best way to get a consistent mixture. I have access to Sunoco 110 oct leaded fuel from the pump, but I have a buddy that recommended that I use concentrate instead.

Just wanted to see what you guys have had the best success with...... and please don't say E85.

TIA.

That's what I'm thinking but I just wanted to get some other opinions before I went and did that. 7.5 (110) and 7.1 (93) nets me approximately 102 but I just wanted to see if this was the recommended way or if there were other easier / more cost effective alternatives

E85

Thank you for getting this out of the way good sir.

I run straight ms109, it is oxygenated and even on a pump gas tune will still increase hp over 93 octane.

But its expensive as f*** $15.50 a gallon lol

I had a 100 octane tune that I could fill up with at the pump from a local Sunoco station.

If I had 100 or 102 or even 104 oct around me that would be ideal, but 110 is the only thing that I've seen... Not that it couldn't be done but I'm not crazy about the idea of having my car tuned for 110 leaded race gas when it's my daily. Not to mention, 14.5 gals x $6.50 per gal is almost $100 per fill up lolz.

Go buy 100LL from an airport
100 octane and low lead content
should be about 4.25-6.00$ a gallon depending on the airport

Are you forreal? Will my car fly?

[RedB5S4]

Yeah not too crazy about the idea of jet fuel either.

It's all good, found some 101 oct green green purp scurp for $4 and change per gallon so I think that's what I'll probably end up doing. Thanks guys.

I got some odd looks filling up my b5 with 100LL at my airport lol.....Had to explain to the grandpas it was ok for it

Just curious why you don't want to run E85? Unless access is an issue, it seems like a much more cost-effective solution than 102.

Lead will fowl your O2 sensors, something to keep in mind.
