come on now, i don't even have a fast and furious wing or stickers on my doors from parts that i don't have yet boo ricers

The point of going to a higher octane fuel is so you can run more spark advance and a leaner AF ratio..

I don't know what makes the most power on a NA car in terms of AF ratio and timing advance, but on FI, Kenne Bell found that 25 degrees advance gives about the most power, more advance in their tests resulted in lower power. As far as AF, in an FI situation, you set the AF ratio to be as high as you can without pinging.. it all depends on the amount of boost and the octane of your fuel.. I believe the 110 octane race tune they use is around 12.2 AF ratio.. that is pretty lean for FI..

Just remember, the higher the octane, the harder it is to burn the fuel. It isn't like higher octane means more energy, it doesn't, it just gives you the ability to get more compression of the air fuel mixture (or spark advance) before you get pre-ignition (early detonation).

If he is getting it at the airport it has.

I think your tuner is full of it if he is telling you that you will make more power with your combination and 110. I am real curious to hear what his reasoning is. Specifically what total timing he wants to run.

just got off the phone with ryan at am

A/F ratio 14.6-1
timing starts a 2* down low and builds to 15-20 in advance in the upper rpms

he said it should be a noticable difference, with 7-10 more hp and trq. over the curve with the 110 vs 93 tune mabye more depending on the conditions, but not less.

i also asked if i should change my gaps and he said i might gain a little if i open them up with a NA motor and close them 1 heat range with FI

Stay away from octane boosters. Others have found out the hard way that they fouled the spark plugs in their S197 GT engines, and ended up having to replace the plugs.

Torco is actually race fuel and is good stuff.

I googled Torco out of curiosity after having seen Stlwagon talk about it on a couple of occasions. I also came across this write up regarding Toluene:

Toluene - Octane Booster FAQ

Soooooo who wants to be the first?

I've done the acetone and xylene mix... Quit after I melted my fuel rail crossover tube and had a hell of a fuel leak.
