2004 Cayenne 955 Turbo Upgrade Build Thread, Custom Manifolds, BW EFR 7163's
#181
Quick update.
We have several revisions in and the few simple bugs worked out with the custom coding/programming. Still extremely early in the game but the results thus far are nothing short of impressive. Running about 11lbs of boost right now and this thing just sh**s all over a friends 2006 Turbo S I have over here. Its not even funny. Add a lil power and tq and bye bye infamous throttle lag. Now I get scratches if I give it to much pedal pulling away. On the downside my FMIC while large, (24x6x3.5 vertical core) just is not going to be up to the task and we are already seeing a temp rise of around 40 degrees on a 3rd gear pull so this needs to be adressed immediatly. Fitting a high capacity intercooling system of any style whether air to air or water to air is a huge challenge in the Cayenne because of space and just how its put together. Right now it looks like I am going to stick with air to air and have Bell make me a cooler that utilizes one of their 24x14x4.5 vertical cores. Bell is really awesome and we are already working on some cad with solidworks to develop one.
Unfortunatly I won't be able to make TX Mile this year but quite a bit of progress is still very close.
I am including a log file to give you an idea of how good the logging is for all you nerds like me. Literally thousands of maps can be logged and presented in the Excel format and then you have visual ME7 that can show graphs.

Niiiice. Have you thought about CO2 spraying the IC? That's what I have on mine, it drops the temp instantly and it's good for quite some run time.
Btw, my friend tried air/water ICs on his q7 because he wanted better cooling while offroading and promptly went back to air/air as it couldn't keep the charge air cool and actually fluctuated more than original air/air

Or just use a co2 fire extinguisher for testing. The way we did it on mine is we bent a copper tube and made small holes in it, sealed one end and made a double S in front of the IC with holes pointing to the sides and towards IC. When I hit it, it would instantly vaporize on the ICs and cooling by A LOT. I don't remember the actual number but all that was needed was a 3 -5s burst. And it looks cools AF when you hit it on a red light while idling - white fog kinda oozing out of wheel wells and bumper ;-)
I can make some pics when I get my porker back from steering replacement.

Got the new FMIC that Bell designed for me today! Pics just don't do justice to the quality. I highly suggest working with Bell for your cooling needs. One of the BEST experiences I have had in this. Hat's off to the professionals over at one of the oldest names in turbocharging and especially Jonathan Gwinn who assisted me. 9 emails, probably 5 of them revisions, and 12 days later I bring to you the worlds largest and most ridiculous FMIC a Cayenne has ever seen.
Before. This Treadstone unit was a decent cooler and something like this could be a good upgrade for the stock turbo guys. I picked this one up new on ebay from a private seller and paid only $160.

I would have just done a single 3.5" like I have now but the real problem is the hood latch. This IC takes up every last inch of space available and the two outlets allow the latch to sit in between the top tanks. I don't want to pin the hood and eliminate the latch. The top pipes are going to be interesting bends and I wont know exactly what until I get the IC mounted. I'm really pushing limits of what will fit. I am also going to trim a section of the front air duct radiator shroud out and lay back/trim/reinforce the crash beam to increase airflow to the bottom half of the IC. It sits in the same spot as the first FMIC but the extra inch in core thickness go's to the rear to the rear. Bottom inlets are now going under the crash beam. I'l try to throw up some pics as I get in in.

Top of bay shot.
A few pics of the progress.
Old hardware off, ready for surgery.
Thank god it fits, barely, cuz I own it now.
Shot of the outlet end tank.
Inlet end tank with the airflow divider/channel. This ensures that the incoming air will be distributed evenly to the whole core.
To fit this big IC I had to clearance the crash beam for the lower inlet pipes. Here I took sch 40 steel steam pipe and made a couple cutouts.
I cut a strip from the top of the beam to give the bottom couple of inches of the core more flow.
I sectioned the piece I took out of the top and welded it to the inside to add some strength back. Welds look like crap because I didn't have a sander that would fit in there to strip and welded right thru the paint
Top shot of the bay and the y-pipe I fabricated from a u bend. 2-3" inlets to a 3 1/2" outlet.
I love pie cuts because they are so cheap and the bends you can make are infinite. This is a 3.25"CLR from 3" tube, 15degree total slice with a 1.23" long-long side.
Driver side cold side passing thru the core support.
Some of my better beads.
Drivers hot side.
There is no space left.
Pass side hot side. Trans cooler and PWM controller in pic.
Maybe by the end of this weekend I can have it back together and running.
