Intercooler sprayer. - BMW 3-Series (E90 E92) Forum

The Suby STI has a water sprayer from the factory, comes on under full throttle when activated. We (in the US) have the empty battery box that woud nicely hold a gallon tank of distilled water and a pump. Or is this just not practical?

First post, picking up my 335 in a month and a half.

Hmm and we also already have a somewhat high pressure sprayer with the headlamp washing system. I'll bet it could be done. Have to check that out. Thanks for getting the brain working.

It doesn't even need to be high pressure it is all in the nozzle(s) the more finely atomized the water the better.

Given the modest boost these cars run stock, I doubt you will get any performance improvements. Maybe with a procede.

If anything a Co2 sprayer would be better than water. Probably cheaper than a water pump.

Well, you'd have to ask AA if they would do it for you, but, the XEDE has a spare driver circuit to control Intercooler Water Spray directly - mapped relative to RPM and operating boost pressure. You'd have to figure your own tanks and nozzles though unless you can convince them to do the lot as a kit or something.

I always figured the windsheild washer would be perfect since you already have the tank with pump and a switch on the steering column. You would just need to run the tubing to the intercooler.

A JAZ 1gallon fuel tank from a kids dragster and a small 12v pump work just fine. I have put them on other turbo cars before (RX-7's can damn near cook a t-bone on their intercooler after some hot laps.)
