Any reason why you're looking at this option?
Only real reason to increase oil pressure is to increased redline on the engine, or if you're running serious amounts of power - i.e. over 400hp?
Other than that, there's no real reason to do this on a daily driven street vehicle.

The Racing Beat 85psi(?) street OPR upgrade is good enough for most applications.
It's reasonably priced too.

I'm considering the FD OPR simply because it's a cheap mod to put on while the engine is apart. $34 for the FD that I'm told and have read is a 105psi OPR. The RB OPRs are all in the $100 range. Am I missing something that would justify RB charging almost 3x as much?

I'm running mostly stock S5 13B turbo. My mods are in my signature, that's alot easier than typing them out in threads. I'm looking more for reliability and longevity than added HP. If I can toss on some mods that are cost effective and won't affect driveability I'm interested. Somewhere down the road I may do a BNR or even find a core and start a new rebuild and have more fun with that engine.

Is the only benefit at high rpms when oil pressure tends to drop? Does the higher pressure equal to more flow, more cooling and more or better lubrication across the RPM range? Or is the only benefit to higher oil pressure at higher rpms?

See above:
RB OPRs are $100
FD OPR iss $34 and is a 105psi regulator

I'm always suspicious when you can get the same thing for less cash. Hopefully some people will chime in with experiences, knowledge, etc.
