torco fuel additives ??
 

I've seen this stuff addvertized in two mags a hot rodding mag I get and one of the most recent import mags had a thing on race fuels. Anyone familiar with how well this stuff works? Manufacturer states up to 107 octane when used with 93 octane premium. I want to try and have as close to a 100 octane rating this spring when I bring my car back out and this looked like some thing a little easier to transport around then say trying to fit a 55 gallon drum in a 7 LOL :rlaugh:

It's worth a couple points but it won't magically turn your pump gas into race gas.

Buy the real stuff!

Use Avgas
 

If you don't want to pay for racing fuel it is often easy to find a smaller local general aviation airport that will sell you 100LL fuel for about $3 to $4 per gallon.

Aviation fuel is a no no. Especially in our engines.

RR,
I'm curious as to why you would say not to use 100LL in a rotary. Leaded gas is leaded gas. Assuming the car is not running catalytic converters and the owner is willing to change out the oxygen sensors every 5000 miles or so I don't see the issue. Lead has a BIG anti-detonate effect on boosted engines and might even help with sealing in the engine. Although lead build up over time would be an issue.
Thanks,

100LL has alot of detergants in the fuel to cut carbon build up. If you use it in a engine not desinged to run on it it will break down your seals. And in a rotary engine you need oil to burn with your fuel so it does quit the number on your apex seals being deprived for its life giving oil.

Not all leaded fuels are created equal.

Apex seals are metal, avgas isn't going to hurt them any. The oil and coolant seals, which are a little more fragile, don't really come in contact with the fuel. And I really doubt that the additives in the fuel will hurt oil (even if you run premix) when they won't hurt the gas itself, since oil and gas are practically the same chemically. If you DON'T run premix, the oil and fuel are in contact for, like, 1/10 of a second, so no breakdown there. Not to mention, regular gas has detergents in it too, heck gas companies advertise their detergents as a benefit. On top of this people put rotary engines in their airplanes and those run fine on avgas.

I'm not going to go so far as to say that you are absolutely wrong, but I will say that I'm not convinced. The main problem with leaded gas is that it eats oxygen sensors and catalytic converters, and of course it pollutes even more than a normal emissions-uncontrolled rotary, and it's illegal to drive on the street with it, but I don't think it will hurt your engine internals.

Ask dan at atkins if you dont believe me than. I am just saying it isn't the same. Seals are seals they are effected by fuel if you chosse to beleive me or not. Thats why you can destroy them by running to rich as well. It doesnt matter if they made of metal they still wear.

When people add a rotary engine to there air craft it is labled as experimental so they dont need to go through as many FFA inspections like a certified aircraft would. And the benifit of doing this means you dont need to run Aviation fuel in your air carft, most with rotarys run standard pump fuel.

Av gas sounded good till you brought that up but even I'm apped to belive it wouldn't really hurt over time I guess the coolant seals might leak but I'd more then likely have rebuilt the motor again before that happened I plan on rebuilds every 40,000 miles give or take a few. My dad used to run aviation fuel in all his 2 stroke motorcross bikes and they ran great on it never blew an engine till I started going cheap with regular 93 octane.

It's the Federal Aviation Administration (FAA) not future farmers of america (FFA). And just exactly how does a pilot find standard pump fuel at an airport? They can't, because airports sell Avgas, and you can't exacly taxi on over to a Sunnoco can you? Rotaries can run on 100LL period... You are giving some straight-up wickapedia mis-information. Such being the reason for me bringing this back from the dead.

Unless your car is boosted higher octane fuel will lower your performance on a rotary, not improve it.
