Final test of the intake. Installed the high-flow filter provided with the Carbonio intake in place of stock. More improvement, but there is still a slight bit of restriction:
I'm not worried about it....I'm guessing maybe 3-5hp tops. Once I get my hands on a VWR intake, I will repeat the test to see if the restriction goes to zero. Remember that restriction is only part of the equation. You can remove your filter box completely, have zero restriction, but have less power(engine sucking all of the hot air it wants from the engine bay). I am gathering the MAF and IAT logs now to see if we are reducing restriction AND reducing air inlet temps. That's the golden combination(while maintaining adequate filtration of course!).
