Sorry for blowing away your reply. Was totally not intentional. :-/

PS, sweet setup.

Looking at these two designs side by side and then thinking about a nozzle holder with a single bar either straight across or just coming into the middle... the single bar seems a lot less restrictive and will likely be the one I get made for my mighty K03.

What are advantages of the extra bars? Strength won't be an issue with quality materials/welding. Do they straighten airflow at all? Simply make it easier to get the nozzle dead centre? It would be nice to see airflow modelling to actually compare the performance of more-vs-less cross bars... anyone care to do that

Like Doug said it's just a prototype, The main issue I see with that mount and going with a 1 bar bracing system is people torquing down to hard when they install the tip. I mean you can put torque specs in the instructions and bold them and make them 200 size font, etc. etc. But you know people are gonna over torque the **** out of that thing somewhere. Ideally instead of putting it in the pipe you would wanna somehow mount it right at the compressor shrouding, that way you have to torque so hard that your messing up the shroud before you have a chance to damage the piece. I believe that is where Richard from aquamist design's was intended to be used. Now if the clamping force from the hose clamp is enough to hold the piece in place via an interference fit type situation, that would be great. Also consider a nozzle holder and a water line also need to be ran within the airflow path as well, which is going to create more of a restriction. Overall it seem the restriction caused by all these parts in the actual air flow tubing of such a small radius, might negate the benefits of this type of injection. Of course the only way to know is to test it and see what you come up with.

I would not want an interference fit piece that goes in the compressor housing inlet... that's just asking for trouble, IMO. It should simply be pushed back far enough that it clears the inlet when the TIP installed/clamped down. Problem solved.

If the interference fit is done correctly it will work without problem, I mean hell valve seats have been interference fit for years, take a LOT of punishment and no one worries about those causing a problem =P

"We are all saying the same thing" Doug it's time to cross the bridge again and go see Ed for Version2. Maybe we can coordinate the move and combine ideas. I need to pay him a visit anyway to have one of my Air-to-Water pipes aluminum welded.

PS: We also need to discuss F23

I'd still be weary. I don't want anything flying into the turbo at high speed.

maybe look into smaller diameter line and a smaller profile nozzle holder for the pre compressor stuff on the small k03-F23 sized turbos. IF anything smaller line would increase the water pressure coming out which in this type of application is never a bad thing =)

Could probably do flared fittings for hard lines.

Glad to see that wasn't totally lost on everyone

Thanks for sharing! I would love to see a follow up on the erosion on the blade when you get to it

I finally got to this today. The after picture is a lot closer than the before but the results are obvious. Not to be dissuaded… I'll simply need to change the strategy when I swap this snail out. Someone chime in with their successful method

[Marcus_Aurelius]

Thanks for sharing All_Euro! From briefly looking at the pictures, the erosion seemed to be concentrating on the outer leading tips of the blades which would suggest that it's mostly from larger droplets pooling down from the TIP ID. I would think that revising your nozzle placement should take care of that!

Edit Reading back your nozzle placement you definitely have pooling on the TIP walls dripping down towards your blades! That was my initial concern asking for post-spray pictures of the blade erosion. I will post pictures of my nozzle mount tomorrow if it stops raining here in NYC

That would be awesome - I'd like to see what's been working for you. I have another K03 that I'll likely port & install next oil change... & definitely with a new nozzle location

Did you end up getting any pictures of your nozzle mount?
