The original link shows 0.7mm (not 0.07mm).......

You're right in pointing out that that's a huge disparity, crono! I don't speak German, so it didn't really resonate that the "0,7"mm shown on that site meant ".7"mm , so ~ instead ~ I just went with Matt's figure of .07mm......oh WELLLL, lol! 

BUT......in spite of the fact that some of the area figures I presented were wrong (I blame the narcotic pain relievers I've been using to compensate for major back surgery I had nearly two weeks ago) ~ you seemed to imply that your flow-percentage comparisons of the 2mm vs 1.6mm restrictions were based on hole diameter  rather than hole area,  crono. Oddly enough, however, "MY" area-percentage comparos remain approx the same as "YOUR" diameter-percentage comparos ~ so, perhaps I misunderstood the basis' for your comparisons?

In re-doing the math, the 1.6mm-diameter restriction is NOT 80% as I originally calculated, but rather about 64% the size of the OEM 2mm restriction.......the same figure you came up with. AND.....the .7mm diameter restrictor ALSO comes out the same as your calcs at approx 12% the area of the 2mm restriction.

I used area as well which is why we came up with the same percentages

Hope your back is feeling better!

It is, THANX! [Image: happy0034.gif]

It couldn't have felt much worse than when I awoke from the general anesthesia used during surgery. I was on a morphine "drip" for a week, with the option of pushing a little hand-held "pump button" to turbocharge the dose. It got pushed a LOT! 

I'm nearly 3 weeks "out" from the last of a 2-part operation (where they fused the sacrum and 5 lower vertebrae [L1-L5]  in my spine.....with bubble gum, duct tape and super glue). I'm currently "tapering off" of Norco (opioid pain reliever) and Zanaflex (muscle relaxer).

I'm looking at the site for these restrictors and they're showing 100 plus dollars for shipping? Is this something anyone else encountered?

You might want to contact them and see if thats correct , you also might look at turbosmart has an adjustable regulator for the turbo oil feed .

Does the "tube-adapter fitting" you're presently using look similar to the restricted fitting on that linked page Redmanrunna?  If so, you might consider soldering closed the existing hole in it and redrilling with a .7mm or 1mm drill. If it's stainless, use silver solder......if it's aluminum you're bummin', lol. 

Regardless of which type of fitting you use to restrict the oil supply, however, I suggest using a small-micron filter upstream to make sure that a small particle doesn't plug it and ruin yer day. <shrug>

You can only get that particular restrictor from Germany, but it really wouldn't be hard to improvise one. One example would be to use a common M12 to -4AN adapter and partially thread the inside for a drilled set screw. Drive the screw into the bottom of the thread to keep it from backing out or stake it.

Sorry I don't mean to high jack the thread but I'm interested in running the efr 7163 down the line

What rpm do you start to make positive boost and what rpm do you have full boost by? Also what cam are you running and which AR hotside? I'm planning to go t4 divided

with my 2.5L i can make 30psi brake boosting it under 3000 rpms.. around 2800 according to my logs. its a quick spooling 600hp capable turbo. 

I have the T25 flange.

I've read that the ones with aluminum centers need water cooling, whereas those made of steel can get by with just oil cooling ~ but.....DUNNO!  :dunno:  <font color=navy>

correct. mine has and always been water cooled. even my steel center one was.

How did you setup the water cooling? Curious what type of system you ran to achieve that.
