Gents,

Is my “two hole fuel tank principle ” believed or not?
I did not get response, only a personal message with important info.
So an post with a second description because it is important:

What could have happen when a World famous photographer did have his roots on a Triumph motorcycle.

When a combustion engine does not get his ideal mixture of fuel and air, than you get not all the power you want.
Two clicks more open of the needle valve is destroying energy, during horizontal flight!!!!! (see picture 1)

The too much amount of fuel has to be evaporate, heating up, and so consumes your extra thermal power during the transport through your little engine. You lose power by generating all kinds of drag.
It also uses the room in the little combustion chamber without doing anything else than let you lose the contest game.
Most important Dutch fact: money

To get the right ratio the fuel pressure is very, very, very important! Very important! Yes very!
To fly inverted the ratio is again double more extra important because of the extra drag of the plane with his asymmetrical wings and position of the fuselage.

Did Ed know that, Let us take a look!

Ed was a mechanical engineer or machinist. These were his roots of all he know about combustion engines and that could be a lot.
One important “extra” to win with his Triumph motorcycle for example was , a "roots" compressor to get a great amount of combustion air through the carburetor, with all the necessary modifications on the carb of course.

And then later? With the combustions engines on his airplanes, no problems with the fuel/air ratio, also not inverted?

I did not think so if you make the fuel tank the best you know in that period.

The picture2, the roots compressor, when you forget the modifications on the carb the fuel is blow out the float chamber and of course Ed did know that.

The picture 3 and 4 again in better pictures the two hole fuel tank, right European and wrong the USA type.

Who did explain Ed the European fuel tank when he was in Europe in 1960?!!!!!LOL

Picture 5 compressors are sometimes bigger, the instrumentation the same, Daniel Bernoulli, not the Roots (displacement) but with diffusers inside, a lot of them.
Picture 6 My “ROOTS” does not have a belt drive but a static, the carburetor problems can be the same

Ed did know it all, so I THINK he did use the best fuel tank system in his contest Taurus. Which I can only guess.
I will use the European fuel tank principle again in the Wester Taurus even with the muffler, I will make the strongest rope a second time.


For a while the first picture again: THE weakest string of the King? Sometimes you can see it from a big distance, we do so and Ed did also, he was often warned before the contest started.
Do not tell me it does not matter because we know Ed in Europe and not you.

Next time about the K & B 45 engine and the picture of the King Pin, one more time, before we continue with the building.
Because what to do with a European fuel tank and a bad engine? We all want to know it all.
Propulsion in the rope, of winning the contest, are two strings twined together, because they have to do the propulsion going better.
