Me too. I agree that Jeff knows what he’s doing, but it seems only to apply on a dyno where the heat soak would be at it’s worst. Once the car is moving, quite a bit of air passes the entire IM area…so heat soak shouldn’t be much of an issue. I could be wrong, but I think Honda had a reason for doing that, even on thier F-1 motors.
I found an IAT as well if you can’t grab one from J or Rogue…it might get lost in your hands though
