yeah I checked there first and seen nothing.

I found this post from a couple of years ago on another forum,

"Jon from Full Race got me the answer. So FYI

-max EGT for the EFR turbos is 950C
-max turbine speed is rated in terms of "tip speed" and 560/ms. The specific RPM that 560m/s tip speed occurs depends on the diameter of the specific compressor wheel in question.
-oil pressure is regulated by the built in oil control orifice. Pressure range is stated as 30-100psi. we've had motorcycle and ATV customer engines at 15-20psi oil pressure and no issue surprisingly.
-bearings are m50 races with ceramic balls in aluminum cages (silver plated). Dimensional Tolerances are considered BW proprietary information and not shared outside of their internal engineering center.
-most of the EFR compressor wheels have 14 blades which corresponds to 2917 Hz (except the 6758 which uses a 12 blade wheel)"

but it just strikes me odd that, I had 40 PPM silver content and the zinc content in my oil was 1700 after 3000 miles, so probably 1800 for a VOA

prior to that, running Motul 5w-40 I only had a 3 ppm silver content and I was hard on the turbo for those 3 months I ran motul.

nothing changed between mechanical wise between the Motul and the RLI 5w-40.

How did you like the RLI altogether? Have been considering switching from Motul xcess 5w-40 as UOA show it shearing to a 30. Although if its going to eat my EFR bearings... that's an issue

it stayed in spec very well. but I still think the high zinc content is eating the bearings

Isn't the Motul pretty high in zinc too though? I wonder if there's some other component to the RLI that causes the reaction with silver

If you want lower zinc, yet really good oil, 300v substitutes their zinc with boron.

Not sure if this has been mentioned before in the thread, but Iíve got an IRL EFR7163. I should be able to swap the compressor housing out for a standard one so that i can fit a filter/inlet on there, correct? Much cheaper than machining a flange and inlet piece.

Yep. I was going to do the same thing with my stock location 7163 so I could get the bigger inlet.

I know this isn't a fair comparison and i was just curious after driving her car for a week. but I plotted my wifes 2011 WRX Cobb OTS Stage 1 vs my 7163 boost plot. hers felt so laggy compared to my car, and 4th gear for my car is 1.366 ratio and a five speed is 1.30 ratio so its close enough. I need to start both cars at 3500 and see then haha

The Saabaru rotated kit is all buttoned up. 7163TS IWG, AWIC, vanjen clamps, etc. Waiting on Johnson Tuning to start with the e-tuning.





My FFR 818's new low mount 7163 SS EWG manifold is starting. Will be interesting to see how it works this time around with substantially unequal length runners. The dry sump pan and tube chassis are helpful for packaging.

One thing I do remember, when my car was selected on the dyno, it listed my weight at something like 3,6xx lbs. I'm starting to think that had a roll in this?


EDIT: Someone posted a picture after my first pull... The weight is definitely wrong, but I also feel like the HP @ 50 MPH seems high as well. Anyone else have this data on their car running on a Mustang Dyno?

I happened to stumble on this from Krang's thread... My numbers are low because my vehicle simulation numbers were high, and I thought they were.

Does anyone have any comparison of the 7163 prototypes vs the current production units? I have one of the prototype units that I picked up brand new 6 months ago and am loving it but would like to know if there is any considerable difference between the two later in the powerband? I am considering selling it and picking up a production version if there is much of a drop.

The prototype had a smaller hotside and slightly less aero on the wheel. The current production 7163 only comes in the bigger hotside (.85) and has several wheel updates. If you have one of the .64 ones I might be interested.

.64 AR would be nuts on this turbo. Due to altitude, we can get away with smaller AR housings so I wonder how a .64 would do at my altitude.

did you build your own kit for the 92x or buy something off the shelf?

Built my own. I utilized the factory twin scroll header and built all the rest... twin scroll uppipe, intake, downpipe, intercooler setup, etc...

I am wrapping up my engine build and decided that while I have everything apart that I want to convert my 7163 from IWG to EWG. I am wondering if anyone has any good pictures of the stock location uppipe installed that they could share with me so I can plan the flange placement?

I found the source of my oil leak... I determined it was the fitting the last time I tried to fix it. I replaced it with another fitting, steel vs the aluminum one provided by Full-Race. Both where too long for the flare to seal up on the stock end. I picked up a Blouch oil line with adapter, and used just the adapter as it was clearly a proper fit.

Nice to not smell burning oil when it's nice and hot, anymore.





This may have been more apparent to me if I could actually see in there.

I'm glad I utilize map notes as when I went to preload my IWG spring, I could not remember exactly what it was prior. What was set in my head, was not what I posted here. My memory was correct at +7mm preload and I went and took it for a test spin at 9,000 ft ASL and I got it right. I do think I will add another +1mm tonight. It is following target well, as well as my altitude correction. I command ~23 PSI up here, ~26 PSI near sea level (both tested).
