Default High RPM wet sump??

Not sure what oil pump to run on a twin turbo 427 that has plans on seeing 7700-8000rpms. Would like to stay wet sump if possible or max RPMs on a wet sump setup.
Have some suggesting the Melling 10355

You can do almost anything for a short period of time. Are your high rpm pulls going to be limited to quarter mile or less, or are you going to do longer duration runs like half mile or full mile?

Are your turbos fed by engine oil pressure?

Oil cooler?

External wet sump is likely going to be your best option, and internal wetsump might work if you only plan on doing short bursts of high rpm.

Main Focus will be 1/8 mile and only plan on seeing 75-7700rpms and once I hit the 1/4 mile I plan on seeing 8k max. Track use only won't see much street.

I see track days and Qtr miles, Iíve ran at 200+mph on a 2 mile runway, Iíve got a trapdoor baffle for the corners, no appreciable wear on any bearings on my recent rebuild, Iíve an oil cooler and rev to 7500 if I need to.
