Hi Sorry

 

My question was about poistionig of the map sensor on a supercharger.

I have a 1UZ with a eaton supercharger on top of the block. I am not sure whether to place the MAP sensor before the supercharger or after it. The super charger also has a bypass valve on it which means that some of the flow can by pass the engine.

I would assume that you would want to place it after the supercharger as the temperature and pressure being ready would increase?

 

Thanks

David

After the eaton charger and throttle body somewhere in the intake manifold / plenum. You want to measure actual pressure which feeds the combustion chambers. When placing it in front of the charger you could not measure actual boost. Air flow bypassing the intake plenum is of no relevance for MAP based systems.

Best place ive found is just after the discharge on the Eatons, if your running and air to water aftercooler put it after cooler. If your charger sits very low and you get rapid map fluctuations then try take a small source off each runner into a little collector and take your map signal from there,

Hi

Thanks for the comments. The supercharger sit directly on the intakes to the ports so i will drill a little on this to get the pressure reading from. This is what I was thinking just means a bit of disassembly.

Cheers
