I got the idea one night to do this and after much discussion with engineering the project took off.
All factory piping has been removed except the intake accordion and turbo flanges.
With the original setup there was a possibility of 2400cfm. By simply removing the FMIC design and going with this straight pipe method the CFM rating increases to 4100! Hot air travels much faster and given that from turbo to throttle bodies is approximately 18" speaks for itself.
The plenum has been cut to adapt for water intercoolers to be bolted on with flanges to be welded onto the intercoolers. New throttle bodies will be fitted to the intercoolers so the air will be chilled AFTER being ran through the throttle bodies. We are not sure what to expect from this and temperature data logging will be installed up and down stream on both banks. Each intercooler will be easily removable with the addition of the flanges. Several bolts are needed to keep the intercoolers fixed to the plenum and at 20psi there will be around 400lbs of force trying to rip them off.

Now I can change that F$%KING driver side lightbulb.

Spent 50 bucks at the local lowes and got different sticks of aluminum to play with. The radiator is out of a wrecked 600 ninja (freebie) The pump is mounted to the radiator and You can remove the entire assembly easily for maintenance. Image
The air filters found nice homes after the FMIC was evicted. I am going to fabricate a large solid sheet for a bottom panel and close off the pockets to create positive pressure inside the box but keep the filters out of direct contact with incoming air. Once again, the major design element will be maintenance oriented. Removal of the two screws holding in the turning signal makes for easy access to the filters. Removal of all the turbo pipe and intercoolers turned this car into a playground of possibilities :naughty: Im looking for a used automatic Nistune ECU if anyone has one. Whole purpose of this is to be a unique budget monster so cheaper the better. Image

Holy Fawk!
Very interested in what you are doing, if mostly from curiosity.
Not completely sure what's up here beyond the first page pics, what's the motorcycle rad for?

the motorcycle rad is to pull the heat out of the water intercoolers.

Ive completed all the R and D. Developed a repeatable blueprint that I am having cut on a waterjet and its been a back breaking time consuming chore for 4 months since I thought of it. Half of it was debates of why it wouldnt work. Since it cant...not work and all calculations came out to be a winner I just HAD to do this. Its been a lot of fun and I had a lot of pleasure gutting all the crap in this car and love being able to work around everything. The boost pipe will be 15"-ish on each side...Ill cross that bridge soon. Ive drawn up throttle body mounts and I have to work on the placement. I think people will enjoy the throttle linkage design. When I started with the idea I didnt account for exactly everything that I was going to deal with. What I thought was going to be a one of a kind funky plenum for the hell of it ended up being such a bullseye once math got involved. BTW I did take provisions and the TB plate is already bored for a 2.5" TB and I may make an "add-on" selection of accessories. The bolt on intercoolers can be bolted on either direction. Simply look on ebay or whatever for the placement of the inlet on the water intercooler and I modify that one by cutting off the outlet collector and replace it with a universal bolt on flange. Heres some more eye candy of where I am with it.

There will be even more room when the plenum is surfaced.

btw this is still going on. im actually bolting everything up permanently while im off work for a week. I may not have it running entirely but itll be damn damn close. Since Ive started this project Ive had to learn how to use equipment, mastered running the equipment and ended up that now I am building cnc equipment from raw materials.

With those tight bends, I foresee compressor surge. Any plans on smoothing that out? Other than that, incredible fab work and looks like a cool idea for sure.

Very interesting concept, cant wait to see the real world numbers on this.

X2 on the 'tight bends', in fact like running into a wall there at the turns. The blowoffs when working will interfere with the flow pattern around those curves even more.

Finally caught a break from the norm and got familiar with nistune. Finally started her up since December '16. No clue how this will go down but I know Ive given everything my 100%.

On a side note I finally pulled the trigger and got a fun new gadget.

Wow, congrats on getting it running!
VERY interested in how this all comes out in the end...
