Tested on a Yamaha Aerox (Minarelli horizontal liquid cooled engine). Since most of these cylinders have their peak power at 12-13.000 revenues they have installed the following parts on the scooter for this test:
Stage6 HPC crankshaft (12mm) and Stage6 bearings 149€
Stage6 CNC intake spacer and manifold 62€
Stage6 R/T 24mm VHST Dellorto carburetor 125€
Stage6 Double Layer air filter 27€
The variomatic has been blocked to ensure correct results and three different exhausts have been tested with each cylinder.
Also there were no flow improvements on the engine block done and all cylinders were kept as is using the original gaskets. The P4 data sheets always show the best result (highest power) in red. Since there might be different exhaust combinations used, you’ll find the exhaust model always below the diagram. Rot = red, Blau = blue, Grün = green.

Iznenadilo me kako dobro slabiji spuhovi rade sa jačim cilindrima, mislio sam da će krivulje snage u tom slučaju biti puno nepravilinije.
Zanima me mišljenje iskusnijih cunera o ovom fenomenu.
