Well, I´m bored as heck here at work and was looking around, more out of curiosity, at electronic superchargers. This all got me to thinking, how much air (in CFM) does my engine take in at WOT at redline, N/A?

Also, does anybody think it´d be possible to maybe make the intake a dual intake system? I don´t know if it´s been done before, but I think if you were to do a dual intake system with two electronic superchargers, wouldn´t it potentially double the CFM and possible PSI of a single electronic supercharger? Oh, and ignore the electronic draw on the battery/alternator, for arguments sake.

Just wondering, thought maybe it could be a cool project. :)

alright, first you take the displacement of you engine and get it into cubic inches, not liters. a 1.8 is 110 ci, the 1.9 is 116 ci, the 2.0 is 122 ci. Now take your redline, in the case of the 1.8 7000rpm, divide by 2 - you have 3500 times the cubic inches 110 in this case. 3500x110 = 385,000 ci cubic inches. divide by 1728 to get CFM. 222.8 CFM in this case for the 1.8L. the 2.0 ztec with its larger displacement but lower redline requires only 229.5 CFM just a slight increase. and since the whole idea is to get air into an engine to mix with fuel, the 2.0 just barely edges out the 1.8 in power despite of its 10% displacement advantage.
