Friday, I ran the 15 minute / 2000 rpm camshaft break-in procedure for the K45 camshaft. Right after, I changed the oil and oil filter.
Saturday, I set the idle speed and balanced the flow of the ITB's, then I took the car out for an autotune session and the car ran so well that I went for an extended break-in drive and covered 426 miles.
Sunday, I changed the oil and oil filter and re-adjusted the valve lash.
Today (Monday), I just got back from dyno tuning / testing with the K45 camshafts installed.
If you live only by dyno data graphs the 911S cam may look better as torque is higher, but the K45 carries further and makes almost the same max HP (233 / K45 vs 236 / 911S). But the dyno data doesn't capture driveablity and the K45 cam wins on that count hands down.
I am very satisfied with my decision to replace the 911S cams for the K45 cams. The car is much easier to drive in town or in stop and go traffic and goes like hell whenever I put my right foot down!
Dyno data 911S cams versus K45 cams - all else the same.
