Direct Port 100% H20, Proof of being the ultimate Injection! - Page 2

As long as the water is distilled, then no corrosion.

Water only evaporates if its fully atomized and has a long time to travel aka in the ICP. Direct Port is more for in cylinder cooling. Full water droplets will be seen, thats why these jets are special. Very small for this setup.

Really looking forward to this test. Its somethiing I have always wanted to do but I don't have access to a dyno.

Your results and findings are highly anticipated, by me at least.

If you need help with anything throughout the test please let me know. Not really sure what I can help with but it might be helpfull to discuss theory and test ideas as you progress.

Are you using AEM or stock ECU? Will you have a way to log flow sensor V? Do you plan on installing any IAT sensors?

^^^^
Thanks Dudical!

Great questions.
I am running stock ecu, I personally believe it to be a down grade to switch to AEM. I think Motec would be a upgrade lol.

I have implemented speed density as well.

With the JDM 3 bar map and GM IAT. The GM sensor is in the JDM factory location (before the jets) Will see how this works with the big turbo.

Speed Denisty, nice. I lost track of the progress in that post. Good to see it coming along nicely.

IAT sensor placement was always one of my concers with speed density.

Do you plan to use port injection 100% water only or will you be testing port injection vs. 1x or 2x jets in the UICP? Or possibly even using both?

I will try testing different mixtures a long will different jets in the pipes as well. But starting just the 4 main port jets and 100% water.

As for the speed density, will see Im almost done installing everything.

Sounds good, keep us posted with how the SD turns out.

esevo · Feb 25, 2009, 03:35 PM

^^^ Its running!!! Im so excited, drives fine. I have a check engine light P0069 Map vs Baro ??? Something needs to be changed that i missed im sure... Ill have to look.

edit, I forgot to change the ECU periphery 4 to the jdm code...

fixed

Very Cool!

Good luck dude.

I now the thread got past this but I wanted to comment on this. By using an Aquamist DDS3 you can calibrate the gauge for an expected flow window. Window meaning setting things up to look for under flow and overflow conditions. So, if I have 1 new jet or a known good used jet installed and provided all other things are working as should be, I can calibrate the DDS3 to recognize when there's an under flow condition = partially clogged jet. I can also do this with 2, 4, 6 etc jets. Once the gauge is calibrated then the gauge will notify me of an issue and if the failsafe capabilities of the gauge are hooked up to interface with a boost controller for instance, then I'm good.

If there is an issue for under flow I can remove the jets easily and after placing each jet into a container I can manually activate the system and measure the out put of each jet.........this is easier if I spend time when installing the jets initially so I have a known baseline for reference........If I'm at the track I can look at the spray pattern,......not 100% accurate but it works.

The other thing is that with single jet injection OR with multi jet port injection, Aquamist kits use filters. Aquamist has a 100 micron filter and a 30 micron filter. For port injection OR with injection using tiny jets the 30 micron filter is used along with the 100 micron filter in series to help prevent things that clog jets. the caveat with port injection, is that the jets being used are much smaller more care in maintenance needs to be done.

With W/A port injection think of it kinda of like why the nitrous gurus prefer port injection = most EFI turbo cars are running with intakes designed for dry flow not wet flow and just like with nitrous when there's a need for more precise distribution OR when injecting a large volume of liquid, using port injection is practically required.

W/A port injection is one area where the SRT-4 owners are ahead of the EVO owners..........

sounds interesting I'm looking forward to seeing the results on the EVO!!!

Gotta see this!!! Sounds awesome

PS PM you cell, I only have your works.
