building a high hp 7m, just curious about crank scrapers. Do they make a difference? worth the money? does it matter if you're using a 6m or 7m crank?
IJ.;1658570 said:Yes they can make a small difference, just need to be careful which rods you use as some aftermarket rods don't have the spray holes in the beam so it will wear the thrust surface on the piston skirt when you minimise the splash lubrication from the crank.
You have to order the correct scraper to suit whichever crank you have, I worked with Ishihara-Johnson to develop the 7M Teflon scrapers, they're very effective but a bit noisy if you have a quiet car (think going blubbbb blubbb on your lip with a finger)![]()

IJ.;1659050 said:A proper windage tray can be very effective but I haven't seen one for a 7M, Normal steel scraper will leave a film on the crank due to the clearence required the Teflon scraper is actually trimmed to contact the crank so acts as a wiper.
Did th group A's use scapers? Im wondering if I should stay away from scrapper sbecause I don't have oil squirters.IJ.;1659182 said:I used mine with the Group A Magnesium pan with baffles and tray![]()
IJ.;1659251 said:Nope well sort of, they have louvres in the tray.
Do you have the holes in the rod beams?
