OK, so I've made it all the way through this thread.Just an FYI to general audience reading this very informative thread and may be new to the Ford Mod Motor World and 5.0 Coyote (thanks to @socketman for starting the thread) - the stock OPG should be a consideration for upgrading and here’s a good article covering the “why” of OPG failures:

Notes:
If the car is used hard or is more dedicated to track use (drag racing, road racing or auto-x), where the car sees excessive and sustained high RPM’s, the stock OPG should be upgraded no doubt.
If the car is hardly used, or may just be a daily, a highway runner or grocery go-getter, the Ford OPGs will usually suffice for many miles/years as designed.
AWESOME JOB Socketman and great questions comments by all here!!!
I just bought (2 weekends ago) a 2020GT PP2 A10 tranny car (@ 6000miles on the odo). I bought it for the purpose of supercharging (looking at 3.0L Whipple Stage 2?), with the intent to get somewhere around 700RWHP and still be a reliable, mostly "street/summer" car.. Yea, it will see a few runs down the strip/year and maybe a weekend on a road-course every year or so for "fun"...
Being in the Detoilet MI. area
BUT, NOBODY, until recently, brought up the oil gear mods for a Coyote build until I talked with a local speed shop owner (Don @ Walsh Motorsports, Wixom MI.) who did some wonderful work on a few friends 2013-2014 GT500's.
He said, while it might not be 100% "necessary; if it was his car..." (and he himself owns a highly modded GT500) he would do the oil gear mods as part of my intended build.
Until this thread, there was very little info out there about this mod., so thanks again EVERYONE; this has been AWESOME for info!
I haven't even had my GT in the air yet to investigate, but stupid question; I assume that the motor/whole powertrain gets pulled to do this mod correctly? (Don't laugh at that, believe it or not, I've changed oil pans, even checked con-rod bearings on my 520CID stroked 385 block Cobra without having to do anything besides put the car up on jackstands and grab the wrenches!).
Question: What is the "normal" oil pressure range for a stock GT oil pump?
Granted, this is on the factory dash-mounted OP gauge, but with hot oil I see @15 PSI at idle and 40-50-ish while revving at @3000-4000rpms (I haven't looked what it reads at red line; watching the road at that point). Do those numbers say I have an issue that I should investigate even BEFORE strapping on a blower?
For only semi-frequent street flogging, and @700RWHP, should I go through the effort/expense?
From what it sounds like after reading this thread, the Coyote oil pump is driven off a gear on the crank snout (behind the timing cover). Do people always change this crank-gear along with the OP gears? Does that require messing with the timing setup or dropping the crank at all?
Sorry for the stoopid questions; trying to learn "Coyote". It's a slightly different language to me right now...
If you see my avatar, that is my other street car. I built the plant for that one too.
Give me an old Windsor, a 385 series or even an old FE block, heck, I've even been deep inside a few old school Mopar's engines before too.
But, being slightly different, I don't wanna mess this one up...
