The inner diameter of the barb fitting is .5625" and the hose ID is .75" less the spring dimension it puts the entire hose ID at ~.5625" There is also a clearance issue with the turbo housing and the hose assembly. It leaves me just enough room to sheath the drain hose with some silicone hose cover for heat protection. The feed line has an .125" hole to feed the turbo, but I think I will open it up to .250" which is the size recommended by Garret for a sleeve bearing turbo.
I used a calculator from Gates to get these figures:
http://www.gates.com/industrial/pressure/fluidFlow.cfm
Based on a 15W-40 oil specification from Shell Rotella MSDS
Flow is just a guess, could be more or less.
HOSE DATA
Hose I.D. (in.) .5625"
Hose Length (ft.) .8'
Flow (GPM) 4
Reynolds Number 45
Viscosity 420
Velocity (ft./sec)* 5
Pressure Loss (psi.) 3.64
Pressure Drop (psi/ft.) 4.6
* Velocity must be less than 35 ft/s
Reynolds No. <= 2000 = Laminar Flow
Reynolds No. > 2000 and < 3000 = Transient Flow
Reynolds No. >= 3000 = Turbulent Flow
It seems as though I will be ok.
I appreciate the positive feed back
BTW the turbo is within the 35* tilt range recommended by Garret for proper drainage of oil return line, it flows pretty straight with a slight radius, I just want to make sure it keeps the ID consistent.
There is much work behind the scenes that I typically don't share, got to keep a few secrets, but I do a lot of research before I actually do or try to complete task at hand.
