Already noted that AFM cams will run into issues at some point with RPM and / or stiff valve springs.
This is the internet, given what he wants, I'm giving him the best advice that I can, minimum or stock valve springs on the smaller cams and probably the BTR Lt1 beehive probably would work. 2 guys just posted builds that barely made 500whp with headers, one had stage 3 cam, the other had heads and made 520whp.
A AFM couple cam chat,
visit the following web page, only setup on stock exhaust wouldn't make more then 470whp. It would be lucky to make the power of a FBO car. As for Freya, her boyfriend is one lucky champ. In this instance, the quantity of air entering the engine must be measured, or referred to an VE model in the ECU and corrected against measured data, one channel being mass air flow.
One can argue Kink content, cams, video on demand and adult rentals can all be given away for FREE. It may be using a torque demand map, where throttle opening (DBW), inj PW, Inj timing and ignition timing are calculated to deliver the torque demanded.
