3) Myth of spring tension Is the claim that feathers lose elasticity if they are burdened over time a myth?... Judge for yourselves.... I've gotten and torn apart a fully rusted-together B20 engine that hasn't been touched since 1975. After checking with the farmer I got it from, he confesses that no one has touched the car since it crashed 37 years earlier. And given the flora (and incidentally the fauna) that has taken over, I can't help but believe him. This gives me a new perspective on feathers.... ________________ Stood untouched from 1975 – 2012 = 37 years. Mileage 14,365 miles (Two owners, the farmer's father who collided it and himself)
Suppose it's gone 14,000 miles at an average speed of 1500rpm and an average speed of 70km/h (Yes – yes, my mock figures in terms of rpm and speed are certainly questionable... But it doesn't really matter if the numbers hit here or there, see the big picture.) 14,000 km / 7 km/hr = 2000h 2000 h x 60 = 120,000 min 120,000 min x 750 rpm (camshaft spins half the engine speed) = 90,000,000 Ninety million times!! Thus.. ninety million times the valve spring has opened and closed and then stood crammed together in a firmly roasted block for 37 years. The spring is completely flawless, has not been measurably matted at all.... And as everyone says... "– Don't forget to loosen the spring in the torque wrench"... Bahh!...

... a story about following a boy's dream of building a car as if it were from the 30s, with a very long bonnet... I have now built the world's first and only straight 16-cylinder car engine of all time. There has never been such an engine so far. As a basis, I have used four engine blocks from the Volvo B20, but I have not "put together 4 engines", I have built an engine from its parts. For me, this journey began eons ago with the Christmas calendar Herkules Jonssons Storverk. (Click on the name) As a technically interested 12-year-old, I was fascinated by the fact that the kid was working on an old car and countless hours, and countless projects later I have built... a completely unreasonably long engine.
People usually ask me, "What are you going to wear it for...?" How to answer such a question...... Have it to....... Have it for...... "- I'm going to start it and hear it go..." Just the thought of pressing the black start button, hearing the bendix drive of the starters hit and get carried away by the sound of 8.1 liters in 16 cylinders.... Well, what the saying goes, how am I ever going to explain... To know what the sequence of ignition should be like, to get a "good sound", I built a "smattering crow" (Click on the name) and drove in the lathe. (see photo – ignition system) Anyone who doesn't see the allure of this, surely has no use for my image gallery. The rest of you, watch and enjoy... Speaking of the name HERCULES in 1934... one might be tempted to assume that it would be a model year -34 engine. It has also been my intention to let people draw that conclusion for themselves, because the idea is that the engine could have been built at this time. However, it is only the model name because the engine is newly built. /Pelle
