Just thought i would give you an update on some new nozzles Richard at Aquamist has developed.
Basically the same as before, but with integrated check valves and filters built in to the nozzles.
The benefits of the check valve mounted at the nozzle, is that after an injection event, when the post nozzles go in to a vacuum under engine vacuum, it can suck water/methanol mixture out of the lines which results in water/methanol being consumed when it is not needed, and over injecting, but also a delayed onset when you start injecting again.
The jets have a cracking pressure of 15psi, 30 inches HG so will not open under any engine vacuum/boost, it will only open when the aquamist pump kicks on.
Another benefit of the valves is that they have a filter imbedded in them, to stop clogging and to prevent the nozzle from being clogged.
The nozzles work just as well for pre supercharger injecting, as the supercharger creates a vacuum, and will also suck water/meth out of the lines without a check valve.
Aquamist have for a long while offered an inline check valve, but unless it is mounted right up to the nozzle, you will not reap the full benefits of the check valve the further away it is from the nozzle, the less it will be doing.
Also they offer a 1/8 nozzle now, as well as the 8mm threaded in to the 1/8 adapter, but for the majority the 8mm will be the best way forward but the M8 do not have the filter inside only the 1/8 does.
Just a heads up, some photos below.
