figure out the size needed on a diesel truck but it
should work the same here
Exhaust Flow CFM = ( (EGT + 460) / 540 ) x Intake CFM
To figure out Intake CFM
Intake Airflow CFM= (Engine CIDx RPM)/3456) Volumetric
Efficiency x Pressure Ratio
Then for pressure ratio
Pressure ratio= (Atomoshere presure x Boost Pressure)/
Atomoshere pressure
So if you do not have any boost you would put 0
There is alot you can figure out with math. I am not
sure if this answers your questions but it might help.
Well I got it get back to my homework
Thanks for the break

Then for the ricer crowd, ( (EGT + 460) / 540 ) x Intake CFM)/2 , then
multiply by one big 4" fart pipe? ;)
