C20xe, famoso motor GM preparado pela cosworth, mesmo motor da Mercedes pilotada por Airton Senna, na confraternização dos pilotos
ok!
Wrong tuning you dont polish your intake to a mirror finish 😱
last step with p600,not polish paste.
Szép munka! Grat!!
köszi!Ígyekszek
Never polish intake ports. This will slow air speed and make it harder for the fuel to vape. Should have been dimpled or cut so it has lateral lines
Not. Last job with p600 grid. We made very lot of air flow test, its a good ports profil(golf ist best with cnc)
Thats true and not 😁depends on the different areas of ports
In general the last pass on the inlet should be 80 grit to rough up the port in a swirl pattern towards valves
big mistake to cut exhaust valve guides, they are the only thing with valve seats that ccool exhaust valves
Not,doesnt mistakes.you meassure cfm? Its better
