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....
