"is the nitro contamination unburned nitro or is it exhaust byproduct? also what kind of oil are we talking about? I always wondered why glow engines use castor instead of dinosaur oil. mebbe you could take your top fuel byproduct and mix in some alky and have a good glow fuel."



I was just kidding about the oil nitro thing. The reason it looks like chocolate milk is because it doesnt mix with the 70 weight motor oil . Top Fuelers are running so much fuel through the engine with some extremely open bottom end tolerances that a lot of unburned fuel blows by the rings into the crankcase. The fuel pump on one of these things puts out like 22 gallons a minute. When it is running it is a lot like a glow engine running rich with all the unburned fuel spitting out the exhaust into my face as we try to tune it for the track conditions. The most fun you can have with your nose burning and eyes watering that I can think of. Hope to run Indy next month. Jeffie
