Following his discomfort with the original Merosi engine design, it is often stated that Jano had been working secretively on his own competition engine since his arrival at Alfa Romeo in 1923. This resulted in the P2, a concept which drastically turned around the image and sporting success of the Alfa Romeo marque.
For the 2-litre P2, Jano chose an eight-cylinder in-line engine made from four two-cylinder blocks, a design which increased the engine's reliability. The crankshaft was fabricated from two pieces, coupled together in the middle, and supported by ten roller bearings along the same principle as Merosi's previous design. The compressor was a Rootes-type, and was more compact than those of the competition. It drove at 1.2 times the crank speed for a boost of 10 psi.
