Asin Eaton Type Supercharger.
Intend to use an Aisin SC14 supercharger on 3.8 litre enging in low boost (<10psi) application. My calculations indicate that although this unit was fitted standard to 2 litre engines it should be suitable for my requirement.
It has a swept volume of 85 cf/rev (1420cc) that should provide the required airflow rate of 427 cfm however the flow data I have managed to find for this supercharger sets the max flow rate at 375cfm at pressure ratio 1.8. As the car in question is a day to day drive, I will very rarely run the engine to max power (just want more low speed torque) and therefore believe the available flow rate at a pressure ratio of 1.6 will be adequate.
Are my assumptions reasonable.
