Byron Gen2 Race nitro fuel

I have to tell you few things about the nitro fuel I’ve decided to use this summer for all my nitro vehicles. This is accidentally that I’ve began to use Byron Gen2 Race nitro fuel. Few months ago, a hobby shop gave me a gallon of Byron Gen2 Race fuel to test. The hobby shop owner said he wanted me to test the fuel. According to his face, he was sure that I’ll like it. For many reasons, I didn’t use the fuel immediately. The gallon stayed on a shelf many months, eight to be precise.

One day this summer, I was trying to fine tune one of my .21 engines. I was not able to tune my Novarossi 21 Plus 4 engine to my likings and to get the power this engine usually produces. I’ve tried different glow plugs of different heat ranges, I’ve tried different carburetor settings, and I’ve inspected the fuel lines, the tank and the engine for air leak. Nothing was wrong. This was the kind of experience that can let anybody totally confused!

I then sat back and while I was scratching my head for a solution, I remembered the gallon of Byron fuel the hobby shop gave me. I set the engine back to my initial settings and filled the fuel tank with my new fuel and fired up the engine. The engine was running fine, I’ve let it warm up few minutes and started to fine tune my “un-tuneable” engine. To my surprise, the engine responded well to my carburetor adjustments. In a matter of few minutes, my engine was set exactly to my likings and was exceptionally performing well. The average engine temperature was also lower than normal. Both fuels have the same nitro and oil percentage.

I thought it was a coincidence, maybe something to do with the weather conditions. I took my Team Associated GT2 equipped with a Novarossi engine .12 engine for a second test. From my past experiences, I knew this engine was relatively easy to tune. I started the engine with my old fuel and ran the truck in my backyard for a full tank. The engine temperature was around the 235F. To compare both fuels, I filled up the fuel tank with the Byron Gen2 Race fuel. I had to tune the engine a little bit but this was very minimal. I’ve ran the GT2 in my backyard as I did for my first test run. I noticed a slight boost in performance but what surprised me was the operating temperature of my engine. My engine was running cooler at 220F and was producing a little more power.

I did the same test with a Team Associated SC8 RTR and with a RC8T powered by a Reedy 121VR engine. I got the same numbers. The engine temperature was lower by 7 to 10% with the Byron fuel. All tested engines were idling perfectly, were easier to tune and performed a little bit stronger.

The main goal of this article was not the discriminate others brands of fuel, this is why I didn’t mention what fuel I was previously using. The goal of this article was to share my experience with the Byron Gen2 Race fuel.  I now only use the Byron Gen2 Race 30% fuel for all my nitro engines.
