What is a common amount of water used per pass on a 3000 rpm p pump 466 3 inch turbo tractor. Looking at starting out at 40 ounces |

Would I most likely be adding more water. Not looking for secret amounts just a honest answer |

Time your water,you should start with about 12 ozs in 15 seconds,then go from there. kick it on at 20 psi of boost. Edited 1 time(s). Last edit at 06/13/2013 03:42AM by jd402056. |

40 wouldn't be a bad place to start 50 would probably be better that way you won't melt anything the first pass. Electric or high pressure belt? and I assume multiple ports correct? |

50oz will put the fire out on that setup.
And a bunch of water doesn't always make a first run 'safe' Sounds to me like your lean on fuel. 2oz per sec water 675'cc fuel Depending on your compression ratio and if your in the ball park for timing You should see cylinder temps near 1450-1500 |

switch
|
Is there a benifit to using a pressure switch set at 20psi vs a plain switch on the fuel pump throttle arm. Switch is set to come on at approx 3/4 throttle. Run the rpms up till the water inj light comes on, let the clutch go and go WOT |

The pressure switch is safer, as you will never load the engine up with water when it dies (Either kill it at the start or run out of power at the other end)
The only real benefit of the dummy switch is that it never shuts off, way sleds are built today you travel much of the track with almost no load on the pan so when your limited on rpm and you maybe pick a gear too slow you run the chance of your water shutting off cuz the motor isn't working. all at once the pan drops the water comes on and the fire is out! |
