I'd also like to see some cams for the N18 one day. The problem is the valvetronic system.
Nick at manic said his N14 made 293whp at 1.3bar! ~18psi on a hybrid turbo. Holy crap. He said the cat cams do a lot to increase flow. Lots of power can be gained.
The valvtronic DOES the same as changing the cam....n18 has vanous on both intake and exaust, n14 has it on one....
Valves are programmed more to open at some rpms...varrible valve motors are RARELY cammed....but a good tuner can do it all with a tune...

That's not really the case. You can adjust lift to a certain extent but valve lift is limited by the cam profile and the max 'rocker ratio' the valvetronic system has. Also I don't believe you could control duration with the valvetronic system since it adjusts the entire cam not each valve. An aftermarket cam would allow you to increase the max valve lift and the cam duration. Duration being the real help in improving flow/HP. Cam timing is adjusted by the vanos system.
