New year upgrade

As we know , proton CFE i-campro is about to launch. CFE is charge fuel efficiency and also continuous variable valve timing featured at the intake cam shaft. I have a chance to explore the new CFE i-campro engine. Seems like the cam shaft opening duration is greater than previous campro . The obvious change is the intake port that you can see the port size so much larger than before . I can the divider is so shallow and almost as shallow as my current head which already ported and polished. Another great part is the intake valve size also bigger than before as well. Not much but good enough to increase the Volumetric efficiency ( cylinder fill each time piston trust down to BDC ) . Damn part is i need to have new intake manifold since the intake port was same as CPS .

Come to crankshaft . I can feel the crankshaft mass weight heavier than before but i no chance to weight and compare with the current one. The crankshaft obviously change , you can notice 6 screw holes on the flywheel attach side. So that is another damn part that i need to get new flywheel that 6 holes and able to drive by current starter gear.

While waiting for my CP piston to be arrived . I shall proceed to port and polish the head first .

More to update after January
