Holding 1 bar with uprated FMIC is not really W.I. territory in my opinion.
You're not getting ridiculous charge temps after the IC, so the cooling function of the water is limited. Now if you were holding 20+psi, I understand... I wouldn't trigger the WI before 14psi, as it would bog the engine down, especially now in the winter. |

Should be fine for next summer, part of my plan was to get WI installed before i get the software RR remapped, i going to try and persaude the tuner to increase the boost map to take into account of the WI. Have to put failsafes in place to disable boost if water is low or WI switched off. Not sure how to do that with the zlet though. Any ideas :?: Seen the circuitry on this forum, but im not sure how to disable boost electronically. |

So if you interrupt the electric signal to the valve, that should bring it down to 'idle', giving boost as low as possible (electronically) |

Got some results last night, ambient temps were down to 7 C though, but recorded data at 2 samples per second. Post them on Monday Quote:
Several options available Increase boost/remove precat - planning to Switch off WI for the winter months - if i cant increase boost Remove the IC and record temps at the turbo exit and throttle with WI only - improved turbo efficiency and less pressure losses Position jet directly after IC and as far back from the throttle as possible - Oh isnt that where aquamist say to position the jet :lol: |

Presently my Astras putting out 230 bhp, pretty tame compared to some of these zlet engines

Interesting result
What do peeps think of this graph.
Considerably lower Turbo exit temps, similar IC exit and lower throttle temps than without water injection Without considerable compromise of the IC efficiency Mystery set up Journey Out Sampled at 2 x second Have more graphs to post, but this one gave an interesting result. I will reveal all, but would be interested to see what set up everyone thinks gave this result |

The logged charts are fascinating to read great work, keep it coming.
The earlier ones were not as easy to read as the samples was done in longer intervals. The latest one are great! I am still trying to absorb it all. Did you put the water jet in front of the IC?

I took on board what JohA had said about injecting at the highest possible boost trigger point. After i repeated all the previous set ups i had tried at 2 x second, i decided to stick with the 0.4 and 0.5 jets and record temps with trigger points starting low 4psi and then 7,10,13,14and 15 psi.

In reading the results it would be very helpful if you could chart boost on the right hand y axis. Some way to see where on the graphs that WI is taking place.
