Has anyone any experience with this system from Red Motorsports?
I don't have an issue and don't plan on buying one, just wondering if anyone here has first hand experience. https://www.red-emotorsports.com/shop/Spray...tem-c163183162/ |

No experience with theirs
Used to run an inner tube in the rear trunk Electric pump, old 914 washer nozzle, and a switch This was for sprint races in a type 4 back in the 90’s Great for head temps on a hot day About 15 minutes of life from an inner tube with 7? Maybe more gallons |

I think for a bus its a fantastic idea.
I don't know if its necessary for a 914. But for a bus, especially a Westy, and you are loaded with camp gear and climbing up a mountain - its a fantastic idea to help keep the heads cool. Zach |

I'd like to see some real world testing/data with one of these installed.
I can't see why to pre-order until proven. For now, it's just a "cool" idea. |

I've often thought of use of one of these misting nozzles used in restaurant outdoor venues to spray a minute quantity of water. A tiny water quantity would big a big help in extreme heating conditions. Would need a high pressure pump.
I don't need it for my situation. Barefoot |

Imagine this system has a restriction to reduce the amount of water. Make it last longer
Back at the time. I assumed more water equals more cooling |

At 1st glance I though this was about a turbo'ed intake injection ala methanol, But do I understand this simply is a system to spray water topically on the engine to "cool" it?
So in an air cooled car, you now need a some additional electronics & a water reservoir for a controller water leak? |

Grady Clay used to recommend a similar system for 911s doing track events on hot summer days. He called it the Rubbermaid solution. Basically a bladder with something squeezing it, spraying through a windshield nozzle into the fan. Sounds similar to what brant describes above. Supposedly lowered the heads temps and oil temps measurably.

On an E production, vintage 2 ltr, I ran a windshield washer nozzle pointed into the fan. Water came from cool suit tank. I used a throttle switch for wide open trigger and later added a shifter mounted switch to really cool it on the cooldown lap. No data logger but it helped. We got 5 years from same set of main bearings using a 7600 rev limiter and 11.5 compression So I don’t think it overheated but I did learn to fill the cooler completely. Miss those days!!
