I plan on fitting adjustable cam-pulleys during my upcoming rebuild.
Anyone that have information on basic cam-timing settings to keep driveablility and good low-end torque when using HKS Stage1 264/264 cams in conjunction with adjustable cam pulleys?
With stock pulleys fitted the engine performs very well from low- to high rpm:s (both torque-wise and fast revving)
So I wonder what possible gains, disadvantages etc.. a different cam-timing will possibly give.
Found elsewhere information saying that a few degrees advance on Inlet cam and a similar retarding the Exhaust will improve performance (but no specific info on torque gains/loss specified).
As I am primary looking for good low-end torque (as present with std. pulleys) all ideas and recommendations on settings are welcome.
Engine is 2,6 std. R34-ceramic turbos (Boost 1.10), PowerFC, 720cc inj. about 430bhp at flywheel.
Possibly GT28Rs will be replacing the present turbos..
