Hi All of you,
After a long time working on it, I share you my HFS5 Install (Tephra mod)....
Special thanks to Tephra, Dudical26 and Jack of Trades for the inspiration...

Here we go with the tanks install...





Since It was time to work good, I take the shot to install an AFR @ the same time...


My choice regarding the DDS3 location is on the right tap (right door) to hide it but having it easy to adjust...


I decide to install nozzle right after the IC so I made a little trick on the pipe...




This is how it looks now...


My boost on WI is controlled with a solenoid + regulator
So there are 2reg: 1 for MBC on regular map (22PSI) and 1 for WI only open thru solenoid (28PSI).
Air box was a good place to make that easy...



And I also decide to wire others stuffs at the same time (flash jammer, iPod charger)
Here are my switches...with 2 leds to visualize map switching and failsafe window...


I tried to make everything thinking on failsafe window... here is my wiring (pict links to PDF file)
(probably the most useful on this thread!)


I used a dual gauge pod on the steering to have WI and AFR close to my eyes...


And this is the overview...



I first tried to use VTA but after fighting too much with stalling, I return recirculated now, even I know I will inject some water-alcohol on the turbo when BOV open but as I asked in this thread , I think it should be ok...I let you know...

I will try to add some picts when classified!!

Now I am ready to start working on maps and since I am not very confident with my ECU work, I think to win some time working with Mellon...

I 'll let you know how this works soon...

NEW UPDATED POST 18 MONTHS LATER.... HERE

Looks good, and very well thought out.

Do you mind explaning a bit more what exactly the solenoids located on the air box do?

Vigman

My pleasure Mr Dudical26!
I control my boost generating a leak on the waste gate control line...
Solenoid (WI Overboost EV on schematics) activate the second pressure regulator to make the leak bigger...
I hope this picture can explain how...

Intresting! Very intresting for sure! :-)

I see, or at least I think I do.

Its basically a dual stage boost controller using bleeder valves to bleed off air from the stock boost control system.

what confused me at first was the fact that your boost lines look just like water injection lines...... I was thinking, why is he running WI to the airbox, hehe.

thanks for explaining.

Vigman

It is just because I used pneumatic components to do it ;-)
(in fact what aquamist use for WI are originally pneumatic stuffs too...)
Regarding functionality, you perfectly understood!
Cheers!

Great innovative install indeed.

I am a bit concern about the angle of the jet. Please try a test spray - no intrusion to the spray pattern.

Those pneumatic speed controller are perfect for bleeding air. Be careful some of them are directional.

Vigman

Thank you Richard for your interest! I am not sure to understand what you mean by "No intrusion to the spray pattern"...

I have made some test connecting the nozzle directly on the pump and I made and adjust precisely the extra aluminum pipe part to obtain something like this:


Do you feel it's gonna be a problem?
I am sure to not affect the spray pattern, in fact I am just a bit concern by the fact that boost pressure will distort the spray pattern but as far as I though, I am sure it can only be better than the typical 90 degrees nozzle installation...
What do you think?

The spray angle is about 80 degress, if the devisation from the vertical is over 45 degrees, there is a change the spary may hit the side wall. Thereis not harm in testing it.

Just disconnect the green wire from the fuel injector and gropund it, you will get a full spray.

Here is a more graphical explanation:

Thank you Richard.
I made a new test running pump and injector directly and it looks fine!
Sorry if I took some time to answer but pipe/injector is not easily accessible ;-(
I am now waiting for my APS twin vent BOV to start fine tune with Chris T.
Will let you know...
Cheers!

Good to know. I was a bit worried.

Post some more on going updates, it is very interesting way to set up the low/high boost failsafe switches.

Very clean install! I really like your UICP injection point and the install in the trunk is exceptionally clean. The method of boost control you are using is a little old-school, but it definitely works! The mount on the airbox looks clean, but you may consider routing the bled air back into the intake pipe, after the MAS, not before it (since the air is already read by the MAS.

very nice install...very sanitary! good job
