1st off. I would see no need in running a crank scraper on a street engine..its just that.. a street engine and no need in trying all the little tricks to squeeze out the extra HP..such as scrapers, running lower oil levels etc......
you have to understand what a scraper does. all it does is take all the excess oil off the crank and allows it to spin a little easier...many oil pans have the scraper built in...and it doesn't take away all the oil from traveling where it should.
Just keep in mind that when your speaking of Street engines and Race Only engines its like apples and oranges...
if it were me and i had a HP street engine..i would get a good Street and strip pan with a diamond stripper tray (no crank scraper) and run it...
my 2 cents.
thanks Brian
