I know a Aquamist had their PDM controlled kit (model number escapes me) but running it port style was common from what I recall. If I recall they had the check valves to keep vacuum from sucking fluid into the port as well.

My goofy engineer ass whats to run a tiny nozzle pre compressor (I'm aware of the risks), then another small one post compressor (not enough for it to condense in the intercooler) and then post intercooler.

Get all that heat out. Then again, if you can shoot directly over the valve, and keep your air mass fraction up by not vaporizing the water/meth charge....

Would be an interesting test. I've seen how this principle works with high secondary injectors and the addition time for latent heat of vaporization won out over shooting past the valve.

I wish I was more capable with tuning because I would love to try that.

With the Aquamist setup from what I understand is that you run the port injectors along with a pre throttle body injector that is 2x the size of the port injectors. I've been talking with my tuner to see what the best avenue is for me, he has a lot of experience with the Aquamist stuff so who knows I may stay single injector. I plan on adding some BC 272 cams as well and I am looking at a bigger hotside for the turbo to carry out the power. The T3 0.63 on my SX257 is awesome on the street but adding an extra 500-600rpm might make it a restriction. A T3 0.82 without e85 here in Canada should be the sweet spot with Cams and a good meth system.

I'm running a single nozzle in the upstream end tank of my TMIC right now with success. I wasn't convinced that I'd get even fluid distribution with the nozzle close to the TB.

I may eventually go for a dual nozzle system with each positioned adjacent to the inlet pipes but for now the nozzle is simply positioned between them.

I do get a little excess fueling on shifts which is likely residual fluid in the IC but not enough to cause an issue. My system allows me to prime from the driver's seat so I can also use it to combat heat soak in theory although the car obviously doesn't idle that well ingesting fluid so I need to pulse it for a second or two at a time.
