Protomotive Air Intake Install
If anyone is considering doing this yourself, I just completed the install and took a lot of pictures along the way. The Greddy EBC and upgraded MAF were previously installed, so installation of these two items are not documented in the pictures, although the MAF is simply connecting 4 wires... Todd quoted about 6-8 hours for this job, but he has jigs for everything (and a lot of experience with this kit) vs. the "measure and test fit everything first" method that I used. I have to tell you, I thought this project would be pretty quick and I could not have been more wrong. I have about 60 hours into it. I still have to upload the proper software, then fine tune it via email, but I fired it up today and it started immediately and sounded good. This was a great learning experience, seeing how the OEM air intake, DV's, F-hose, etc. work and eliminating a lot of it and relocating/re-directing other parts....here are pictures of the completed engine bay and IC/air intake/DV's.

John,
Looks awesome!!!!
Got a couple of questions:
Would that design hinder air flow to the IC's and make them less efficient?
Would the filters get dirtier faster being down low to the ground or will that not matter?
Either way it looks really cool

Porschedude, the air filter(s) - one per side are serviced by removing the bumper cover. This is a very easy 5 minute job.
The air filters hug the inside wall and the IC's are pretty wide open. It may possibly hinder flow a bit, but the Protomotive cars have proven to go pretty good with this system. I suspect the filters may get dirtier a little easier, but I am not sure. Time will tell...
Oak, Thanks - this was a lot of fun!
No the intake track is much shorter, about 18" per side from filter to turbo. Also, each turbo has it's own filter with a 75MM feed. The benefit is more air being readily available due to the short run combined with larger piping and increased filter surface area per turbo. I previously had the V-Flow (one of your favorite mods, Oak) with the Protomotive MAF. The Protomotive MAF was never happy with the V-flow and even after a lot of work shaping the "venturi" to improve the idle - I still had hunting at most stops for 3-10 seconds before settling down. This bothered me and Todd told me that he doesn't use the V-Flow (which I knew and tried it anyhow) and with his intake and MAF located just before the throttle body...there are no idle problems. That is what spurred me to do this conversion. The side benefit is Todd has dyno tuned both intakes on this package and has documented better throttle response, and more mid to top end power with this intake vs. the V-Flow, so it should improve performance a bit. Another advantage for my application is that I had the 75mm throttle body/plenum, but all the plumbing leading up to it was 68mm or smaller. This intake removes all the restrictions and runs a consistent 75mm all the way from the turbo, through the intercoolers and up to the throttle body. It will be interesting to see what difference it makes in performance. I have 1/4 mile runs of 11.01 to 11.2 with traps of 131-133MPH on stock tires with the previous set-up. I am hoping to gain the 2/100 neccessary to break into the 10's on street tires. If I can do this or increase the trap to 134-135, I will consider the intake upgrade a performance success. If it cures the hunting idle, which I fully expect it to - it will be a success, as well.

Nice.
I note that the IC brackets need to be trimmed... it seems like a slightly altered tubing geometry could 'tip' the cone filters up at the end and allow the filter to fit and not require cutting of this bracket... any thoughts? Also a flange on the tube would allow you to bolt the flange to the bracket instead of welding it on. (Did that require welding SS tubing to steel IC brackets?)
Thanks for the very detailed pics. I did note some dirt on the floor in one of those pictures...

Adam,
I did consider your ideas and it would be possible. I ended up going the Protomotive recommended route because it keeps the tubing all the way to the inside (the hole saw cut is deep into the upper inside corner of the IC bracket), which is necessary for proper wheel clearance. Also, the welded SS piece becomes the major mounting point for the intake pipes, as it firmly secures their position. For this reason the weld is a better and stronger solution. You also want to get the filter all the way to the inside, so that it does not obstruct the air flow to the intercooler...Adam, my garage has been used mostly for detailing until this winter :-)
Tom, thanks for the well wishes and best of luck to you, too - with your new upgrades...

John: that looked like a lot of work. I can understand now why the 60 hours. I think you also did good in reinstalling the shroud around the ic to provide direct air flow to them. hopefully the results are worth your time and money...was the kit a complete kit or did you have to buy additional items? were your intercoolers already up-grades or were they the stock units?
good job and keep us posted on the results.

Manny,
Yea - it was more than I expected, but I truly enjoyed every bit of it.
This was a complete kit with all parts and accessories included - just add labor.
Shant, Those are the Blown 6 intercoolers and were previously upgraded, although I did have to re-fab the end tank OEM style connectors to the larger Protomotive straight pipe.

Shant, I think they were about $1,700 when I bought them. Here is a link to the web page - they are $1,950 delivered now...

Excellent work!
Mine has a roof scoop and uses that as an intake for a FVD air intake system.
I love the setup & IC's, just what I want to do next.
Would like to know how much the kit is from promotive...
Cheers
