Application Notes:
- 3AN oil feed line is recommended. If -4AN or larger is used, an oil restrictor is required (just like GT turbos)

Additional Information:
- Max warm oil pressure: 5 bar (73.5psi)
- Max cold oil pressure: 8 bar (118psi)
- When starting a fresh engine build or in extremely cold climates – oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
- Do not load the engine with full boost and WOT until full operating oil pressure is present
- Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
