Roots supercharger setup

Postby Fe1957 » Sun Sep 23, 2018 9:37 pm

Running a four barrel with 8 injectors above the supercharger , is there a concern with fuel contamination to the map sensor (it’s an elite 2000) Is so does anyone have an idea of how to isolate , cannot find anything on the net . Thanks

Mount the sensor so that it drains any fluid in the tube back to the point where the tube is attached to the manifold, i.e. the sensor is at a high point with no liquid traps in the tube. Examine factory setups, they mostly are that way.

Are you talking about the on-board MAP sensor?
Wouldn't risk it personally, if you wanted to i'd personally use the equivalent of a surge tank so the air fills a small canister and another line to your ecu is connected to that canister.. That and an inline filter like the late subaru motors have.

Ideally though, just run an external map like with a filter like this.
