Whats the difference between blow through and draw through intake setups?
Draw through is when the mass air flow sensor is before the supercharger and all air from there on is metered. On the draw though systems, the bypass valve has to vent back into the system, as it is metered air, you cannot vent to the atmosphere. A blow through system is when the mass airflow sensor is located after the supercharger and the bypass can vent to the atmosphere. Many tuners prefer blow through because of better drivability and this is what I’ll be swapping to when I re-do my intercooler system on the Couch. For a draw through application (depending on what HP level you’ll be running) you can use the Lightning 90mm unit or the SCT 2600/3000 big air mass air flow sensors. Those are the brands I’ve used or have been involved with builds. Other people have used different brands but those are what I suggest. For blow through most people suggest a slot style MAF like those used on the 05+ Mustangs. I’m going to be using the SCT 5000 slot style MAF when I swap to blow through. Yo
