Default ROAR fuel restrictions?

Does ROAR regulate the maximum allowed nitro percentage as EFRA and IFMAR do? I couldn't find anything in the ROAR rules that indicate any fuel restriction.

IFMAR
Fuel: Rules now in line with EFRA’s maximum allowed nitro percentage.
2.7.a ”Fuel may contain a maximum of 25% of Nitro methane. The specific gravity of the fuel may not be higher a 0.91 grams/cc at 20 degrees Celsius. Measurement will be done with a nitromax 25% in the pit lane and/or anywhere inside the venue. Any fuel detected heavier than 0.91 will means that the driver will have the result deleted from the heat or final where the fuel was found too heavy.”

Well if that is true and enforced, that will trow a monkey wrench into some pro's set up's. I've heard and read several times that they use 40 and 50% nitro blends....

When the nationals were here in Colorado most people were running at least 40%, many were 50% or more. That tracks elevation is over 6000 feet tho. Man that woulda been a crazy race had everyone been restricted to 25%. I heard several people say if they always had to race at elevation they would only run electric so the 25% woulda had people all fired up.

Since I can read correctly, I'll answer.

No, there is no nitro % regulation that is generally enforced... most US tracks and races don't even follow ROAR rules anyway. The 9.1 rule just specifies the fuels composition.
