Miata 1.8L Turbo Airflow

	A	B	C	D	E	F	G	H
1	Air Flow = ((CID * RPM)/3456) * VE							This should be useful for anyone looking to figure out their own turbo for their power goals. Created by TheGrim
2	1.8L = 109.842ci
3		82						(note, this is assuming a built head, for other cases, assume a 6500rpm redline to allow room for safety)
4	Assuming 9000rpm Redline
5	Assume Peak Boost at 8500rpm
6	Therefore, calculate airflow @ 8500rpm max
7	Assume VE = 80%
8				AirFlow (CFM)
