Main girdle or windage tray or both?

If you do go with a windage tray, try to find a screened tray like the Moroso or Canton units. I've actually stopped using windage trays in my motors as we've found that they can actually cost you HP. We've proven this on th engine dyno. With a Canton 7-qt pan on my engines we've seen as much a 7hp more without the windage tray, presumably because the tray was bouncing the oil back onto the crank rather than allowing it to be thrown into the deep pan. Just a thought.

So you actually get more RWHP without the Canton tray than with it? Any experience with the crank scraper? I have both and am veryu curious. I haven't made any back to back dyno pulls, but just assumed the tray and scraper actually worked as advertised.
