Dry Sump Engine - Race Day Priming
Technically a powertrain question, but thinking it'll get more attention here:
I make a habit of turning my engine over (no ignition) to "prime" the oil system before I start it. Will crank it in 10 second intervals (roughly), and usually by the third time will see the oil pressure begin to come up (then I'll start it). The latest engine I have seems to be taking much longer to build oil pressure as compared to others in the past (same make of pump and general configuration of lines, etc). Pressures when running (idle and under throttle) are fine.
There are a couple differences with this engine:
1) I used to use the Fram HP6 filter, but having sold my old system, I'm currently using a Wix
2) The pressure line runs into the front of the block, whereas my other engines fed into the back/lower left
I'm also wondering if/how the "height" of the oil filter (with relation to the engine) could/might affect this?
Thanks in advance!
