No oil pressure in the 1st 8 seconds, How to get turn of the key oil pressure Options

[Vietnam6871]

Engine is brand new 2.3 liter stroker that runs great except no oil pressure in the first 8 seconds then it runs fine with 30 lbs at idle and 60 lbs at highway speeds. Temp runs at 180 degrees normally with 210 being the hottest on very hot days. Any ideas on why it takes 8 seconds? Validated on dashboard guages and a mechanical guage. I can't drive this until I get pressure with the turn of the key.

Thanks for the info. There is a front end oil cooler and gravity could be my enemy. I think adding Accusump might be the answer. I'll let you know how it turns out. This is a 914 after all. Oil pressue is 30 lbs at idle until the engine gets hot then it drops and adding some rpm's fixes that. With good rpm's at road speed it will stay around 60 lbs. I haven't put it on a dyno yet but my guess is about 150 HP.
