Cam Theory 1800

Hello Knutselsmurf,

First of all, I havn't read the other answers to this thread, too many to cope with.

You make some interesting statements, however, the B18/20 engines has been modifyed for over 40 years and yes, they probably would produce some extra HP/torque with additional lift.

But the big problem isn't found in lifter shape, rocker-arms or similar.

There is already an lifter with wider base-plate(mounted from underneath) available, that can cope with higer lift.

The big problem is the three-bearing camshaft, even if you create a sturdy valvetrain the cam-shaft will always bend.

BR, amazonet
