You may find as time goes on that the valve sticks open as you take it away from the tank opening.....fixed with a little silicone spray.

Get the narrow nozzle from MX Store, clip on to your Tuffjug......works a treat on the Vixxen Tuffjug narrow nozzle.pdf

Great find! Seemed a little casual about what would happen if it backfired.

Twas a good weekend. Thanks to Trevor and his crew for their enthusiasm and sponsorship.

From the website AEHS Home The Unlimiteds go flashing through the racecourse, engines howling, air shearing, heat waves streaming. Four hundred eighty miles an hour is 8 miles a minute, and the elite racers take about 70 seconds to cover the 9.1 mile Reno course. If you could take a souped P-51 racer flying the circuit at Reno, slow time down, and examine just one second, what would you find? In that one second, the V-12 Rolls-Royce Merlin engine would have gone through 60 revolutions, with each of the 48 valves slamming open and closed 30 times. The twenty four spark plugs have fired 720 times. Each piston has traveled a total of 60 feet in linear distance at an average speed of 41 miles per hour, with the direction of movement reversing 180o after every 6 inches. Three hundred and sixty power pulses have been transmitted to the crankshaft, making 360 sonic booms as the exhaust gas is expelled from the cylinder with a velocity exceeding the speed of sound. The water pump impeller has spun 90 revolutions, sending 4 gallons of coolant surging through the engine and radiators. The oil pumps have forced 47 fluid ounces, roughly one-third gallon, of oil through the engine, oil cooler, and oil tank, scavenging heat and lubricating the flailing machinery. The supercharger rotor has completed 348 revolutions, it's rim spinning at Mach 1, forcing 4.2 pounds or 55 ft3 of ambient air into the combustion chambers under 3 atmospheres of boost pressure. Around 9 fluid ounces of high octane aviation fuel, 7843 BTU's worth of energy, has been injected into the carburetor along with 5.3 fluid ounces of methanol/water anti-detonant injection fluid. Perhaps 1/8 fluid ounce of engine oil has been either combusted or blown overboard via the crankcase breather tube. Over 1.65 million foot pounds of work have been done, the equivalent of lifting a station wagon to the top of the Statue of Liberty. In that one second, the hard-running Merlin has turned the propeller through 25 complete revolutions, with each of the blade tips having arced through a distance of 884 feet at a rotational velocity of 0.8 Mach. Fifteen fluid ounces of spray bar water has been atomized and spread across the face of the radiator to accelerate the transfer of waste heat from the cooling system to the atmosphere. In that one second, the aircraft itself has traveled 704 feet, close to 1/8 mile, or roughly 1.5% of a single lap. The pilot's heart has taken 1.5 beats, pumping 5.4 fluid ounces of blood through his body at a peak pressure of 4.7 inches of mercury over ambient pressure. Our pilot happened to inspire during our measured second, inhaling approximately 30 cubic inches (0.5 liter) of oxygen from the on-board system, and 2.4 million, yes million, new red blood cells have been formed in the pilot's bone marrow. In just one second, an amazing sequence of events have taken place beneath those polished cowlings and visored helmets. It's the world's fastest motorsport. Don't blink!

Yes, managed to coax Graham Readett out to instruct, hopefully I can soak up some of his wisdom!

Hi, have just joined this Rec Flying forum. I'm particularly enjoying the information to be found in the "Resources" and "Tutorials" sections of this site. Have just become reacquainted with aviation after a 10 year break. Previously flew gliders out of Gawler for quite a number of years, but stopped after realising that work and family commitments left not enough time for safe aviating. So now I'm back as a LSA student pilot learning to fly something with a fan in front. Have recently soloed and now looking to get a few hours up to progress along the chain. Very much enjoying the learning experience, trying to absorb as much info as possible. Cheers Henry
