Hi Gelf,

May I ask where you get that jet adaptor from?
It seems a very nice fitting :D


Richard,

As my questions on the other post, do you provide this?


Thanks,
Rex :smile:

Hi, Richard kindly supplied the adapters :D

Richard, how can I get a hold of a couple of those jet adapters?. Are they threaded for the jets on in the I.D. What is the threading on the O.D. Does Aquamist make any plugs with the same threading as on the jets. I'm experimenting with jet location and I need to be able to plug the holes on the unused locations.

The ID IS 1/8 BSP 28tpi Parallel thread.

I have made a typo - the OD is 1/8 BSP and NOT ID

:D
I'm currently experimenting with smaller nozzles, 0.4mm both before and after the compressor. Maybe the surge issue will be fixed now, we'll see.

My gut feeling at the moment is that Richard's recommendations on water volumes and activation pressures are a bit on the high side.
At least for well-intercooled engines! :wink:

I'd say someone should start with a 0.4mm nozzle at 1 bar, and take it from there.
Stock systems come with 0.5mm minimum and switch preset at 10psi. Too much water for a well intercooled 2 litre engine! Especially in the winter.
