Why are we Porsche enthusiasts? What is it about the brand that draws such fanaticism among its followers? There are multitude reasons, of course, and chances are high that your reason is different than many others. I am a Porsche enthusiast, mainly, because of the other enthusiasts. I am always interested and intrigued by the things some folks will do to profess their love of the brand. This particular Dutch Porsche fanatic just might number among my favorites.
What did this particular Nederlander do to earn my favor? Well, he created the glorious machine you see in the short video here, a near exact 1:3 scale 911 engine. The small aircooled flat six is listed with a displacement of about 1 liter, making it a later SC engine replica presumably. While the SC would not have had carburetors, and no 911s ever had mechanical fuel pumps, I’m not sure it would have been expedient to replicate a 1:3 scale Bosch Motronic system. As it is, the craftsman behind this endeavor spent more than 6000 hours meticulously crafting all of the pieces by hand from factory documents. This diminutive engine has relatively high 10:1 compression, and revs to a stratospheric 12,000 rpm. Not only that, but it sounds like heaven on earth!

1,000 cc displacement? Looks a bit small compared to an air-cooled 1 l. motorcycle engine.
The statement that no 911 ever had a mechanical fuel pump is wrong. If you reference Excellence was Expected (Karl Ludvigsen) Vol. 1 Chapter 19 page 344 shows an image of a Type 901 that has twin mechanical fuel pumps that are driven off of an eccentric on the cam nut. According to Ludvigsen this engine was used from 1963-1964.
Earliest 2 litres used a Bendix electric fuel pump for delivery.The Pierburg mechanical pumps were scavenge pumps for a 'dry sump' fuel system. This system was used to eliminate float bowl surge in 'hi g' conditions. The Solex Carbs lacked traditional floats.
This system made WEBER IDA'S famous !

The original article states that the bore is 25mm and the stroke is 21 mm, putting the model's displacement at just under 62cc. The article also said the scale is 1:3.2 putting the full scale displacement at just over 2 liters.
