This is an indicator and equates to around 10-11 whp gain taking in consideration the RR’s parasitic loss from the drivetrain.

Did you happen to monitor your air charge temps before and after the IC install? During almost all driving situations I notice it’s anywhere from 20-60 deg over ambient. I’m curious if this is an actual stock IC issue or largely to do with the active shutters and low airflow through the IC.Ok, Fabulous Manufacturing absolutely makes the best looking CAI on the planet; truly a work of art! I literally drooled over pictures of that intake while waiting on my RR. That being said, I’ve read at least a couple of threads discussing the heat soak and high IAT’s associated with aluminum CAI’s. I really don’t believe that the cost is all that bad, considering the skill and labor involved in fabricating an intake of that quality. The shipping costs from “down under” don’t help much either. The only thing that kept me from buying that air box was the potential detriment to the IAT’s. I’ve installed the ProCal tuner on my RR, as well as a COBB intercooler, TurboSmart BOV, and K&N air filter. I’m trying to get the best performance I can out of my RR, so if the IAT is high, and the computer dials back the timing, I’m not meeting my goals. I do plan on adding a CAI, but only after the other major players (S&B / AFE / Mishimoto), release their composite CAI’s.
