Pre-Compressor spray 2.1l Twin screw SC

[Richard L]

pre-compressor is good for reducing SC case temperature but not so good in winter if water is allow to freeze and damage the rotors. Just make sure water injection is disabled until the engine is warmed up.

Pre-TB is better so the vacuum does not siphon the water out of the delivery hose so the next injection event is delayed.

What kind of MAF is it, hot wire or hot film? It is better to avoid it if possible.
