I’m guessing this is your compressor map…
VAF of around 200 cfm on a stock Honda 1.6 according to my calcs.
I imagine you’re going to be at 10-16 lbs of boost just to get it up into its efficient range? In that case, I’d guess that DSM 450’s should be fine (get a resistor box or look into 440-450’s with the correct impedance?).
