Yes, the Mass Air side of the deal is the same. The problem is most supercharger guys do not have a Supercharger Flow Stand. Therefore no accurate maps to go by. The only supercharger company I am aware of in the Hot Rod industry who has a flow stand that can do accurate mapping is Vortech/Paxton Engineering located near the Channel Islands, in California.
The efficiencies on a roots type supercharger are also pretty low therefore a lot more heat made and most do not run an inter-cooler after the supercharger.
That being said, the people making superchargers for the Big 3, typically use the factory production boost parts. The 2004 Cobra Mustang is a production example where Supercharger companies offer larger superchargers that bolt on to the factory intake manifold. Vortech/Paxton again makes all their own stuff for the OEMs.
So to say that the supercharger can be figured the same way? Yes if it is a Vortech/ Paxton Supercharger. If you have a Procharger you take their advertized flow numbers and hope it works. Typically most over-build when using the Procharger stuff because a F2 that makes 1400 hp on one engine will make it on a different brand engine. Only deal there is you have to subtract out the power it takes to spin the blower. With the turbo stuff you are using energy that normally just goes out the headers.
