100 Octane Low Lead
Ok so I know lead is used for lubrication purposes, and also helps prevent preignition on higher comp. engines alittle. It also kills cat. converters, but since I don't have any I don't have to worry about it. Now I been helping this guys work on small passanger airplanes and I saw the gas they are pouring into them. Oh it's beatifull, clear-blue tint, and evaporates immediatelly after you wash your hands with it they DONT'T stink. Now i've installed full 3" exhaust and I'm currently running little hight boost on my S4 TII, till I get my wastegate ported, I was wondering If I should try to run my rotary on airplane 100 Octane LL or mix some of it in my tank. I'll probably be running around 11psi, so higher octane would keep me more safe, only concern I have is the low lead part. Would it cause any sideffects or unknown damage to my engine. Anyone have other ideas to help me keep my engine alive except for keeping the foot of the gas?

It will destroy your O2 sensor. The octane rating is different than automotive gas so don't jump to the conclusion it's better. I think it's speced at altitude. If caught you will be fined (no road tax).
How about a boost controller?

100 octane LL is great gas. Lead is a cheap octane booster. That is why it is used. The lead in the aviation gas will help to boost the octane in pump gas no lead. When they are mixed you will yield a slightly higher octane than a straight mix. Yes it will plug cats and ruin you o2 sensor. Don't use it with cats. A Bosh single wire o2 sensor is around $17 to $30 depending on where you buy it and will last with leaded race gas for around 3000 miles. More with Low Lead Aviation gas. How much more I don't know. I am using a PFC with data logit so when I do plan on using the Aviation gas I will just disconnect my o2 sensor. I have used 100 octane aviation gas in many cars before with no problems. You just have to tune for it.
