Convert Aftercoolers

[Shawn Keulen]

Been trying to research the topic. Is is possible or even Ok to convert my raw water cooled aftercoolers to fresh water cooled? Or I have been thinking about possibilities of a bypass valve for long periods of trolling at idle speeds? My thoughts is our 45-55 average deg water is cooling down the non boosted air going into my intake while at idle speeds for 10-12 hours a day and if I could keep that temp up it would help with a cleaner burn at idle?

May be easier to just by-pass the raw water around the cooler when when running at low speeds.. Until you are making at least 150HP ( 7-8 GPH) you do not even have to think about aftercooling with this engine.

If running at 100 HP or less ( 5 gph), you could just bypass the air and let the engine run as a “non-turboed” engine.

You would notice a nice difference as to how the engine runs doing either of those.
