between balls and raceway occurs in non-rotating ball bearings that are subject to external vibration. When the bearing isn''t turning, an oil film cannot be formed to prevent ~rina~ ~mks raceway wear. Wear debris oxidizes and accelerates the wear process.
Oil Restrictor???? | Honda / Acura K20a K24a Engine Forum
5/3/2009· So I''ve been communiing with ATP about using an oil restrictor on a ball bearing turbo or not. They are convinced I don''t need one and that to be safe I shouldn''t use one. Yeung22-I''ve heard of people not using restrictors on their Honda''s causing the seals to blow on their gt turbo''s.
Oil Restrictor On A Garrrett Gt3582r - Forced Induction …
11/1/2008· Oil pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil inlet on the turbocharger center section.

Precision 6262 (journal): oil restrictor or not? - Supra Forums
11/5/2010· hi I have 6262 turbo form precision. it is journal (not ball bearing). Should I use any oil restrictor on it? I do research and some say use, some do not use. My oil suply line us 4AN. I have one restrictor about 1,5 mm (about 1/16 inch) and do not know use it or not.
PROS and CONS of Ball Bearing Turbochargers - Pro Systems Turbochargers
10/9/2018· On Journal bearing designs the oil (just like in your cars shocks) is a shock and vibration absorber. Ball bearing designs will transmit that vibration through the turbo and to its impellers that can then amplify the vibration and destroy the bearings and the shaft and its components. But Journal bearing style turbos ride on that oil, that oil
