You have a 3 litre engine.
It's a four stroke so only two cylinders draw air during each engine revolution = 1.5 litres of air every time (assuming perfect volumetric efficiency)
Close to max revs = 6000rpm = 100 revs per second.
Volume of air consumed at this speed therefore = 150 litres per second.
Now this is your air useage before you boost it above atmospheric ~ in order that plugging this junk into your intake doesn't actually slow the flow down. If you want it to provide (say) 0.33 bar boost then it needs to flow another 50 litres per minute.
If I could design a 12V, minimum current useage electric fan that delivered 200+ litres of air per second I'd be a very happy (and hopefully rich) man. [&:]
