Crank scrapers or plate...?

I see the positive effects at higher RPM's. I come from a street motor world that never sees 7000 RPM for extended amounts of time or peak HP competition motors so I would never consider a crank scraper. Not knowing what the OP was doing was probably an oversight on my part. If these guys apps running high RPMs dictate a scraper and a windage tray, by all means use what works. I myself with my motors ad applications would not consider a crank scraper as I feel its benefits would not justify the cost. Overkill in my eyes, necessary...TBD.
