Educate me some, crank scraper "I believe" is to take oil off the crank to lighten it and bring more horse power?
Originally I thought the windage tray cut down on internal windage to make more power. My ProMod buddy says it's mandatory I put one in or 8500 RPM's will be blowing oil out of the pan everywhere causing issues. If that is the case, why does it need to be so close?
