Before I put ram air on my non turbo diesel I measured 11 inches of water worth of restriction in side the air cleaner at full speed.
After ramair I had no measurable restiction.
Replacing the very restrictive intake on my non-turbo with the ram air delivered an instant 2mpg highway fuel economy boost.

Now I have a turbo just like yours and I am in the process of building a very over sized ram air fed air cleaner with a paper element. There is too much fine dust around here to run something like a K&N air filter so I went with the largest off the shelf air cleaner I could find.

Removing the ram air pipe for A-B-A testing would waste fuel.
How much fuel, I don't know if I care to find out.
1984 chevy suburban, custom made 6.5L diesel turbocharged with a Garrett T76 and Holset HE351VE, 22:1 compression 13psi of intercooled boost.
1989 firebird mostly stock. Aside from the 6-speed manual trans, corvette gen 5 front brakes, 1LE drive shaft, 4th Gen disc brake fbody rear end.
2011 leaf SL, white, portable 240v CHAdeMO, trailer hitch, new batt as of 2014.
