I was just wondering what's the difference between the two? I keep hearing people talk about having eith blow or draw throught but what's the difference? Is the HP difference between the two? If so what is the LIghtning 90mm MAf and the SCT Big Mouth 2400?
 
it is exactly as it sounds.....a drawthrough goes before the supecharger/turbo, and the blow through goes after. Im my application, i needed a blow through because i have two turbos and two airfilters, also a blow off valve. My blow through is a Mass Air Systems and works great....i mean the tune that they gave me was damn close and it has gave me no problems yet.
 
There is no difference with respect to how the meter works.

With respect to how it is installed, there are differences. A draw through will usually have a flange that can attach to the air cleaner.

A blow throgh will not have a flange and look the same on the inlet and outlet so they can be installed in the ductwork.
