Air Box Comparisons
I did some logging with different intake arrangements, and got some nice data.
This car is making something in the region of 200-280 WHP. The intakes using engine air saw about 10C higher air temperatures. I am less concerned about temperatures since I am spraying meth/water.
Series 4 Intake and snorkel baseline
K&N Filter element = +0.3 PSI at redline
Open Airbox = +1.5 PSI at redline
Cone Filter = +3 PSI at redline
At 4500 RPM, the cone filter picks up about 1 PSI, but the real difference is in the top end.
