the windage trays dont just reduce oil spary and misting, they are worth HP, like 10hp at 5-6k on a chevy or ford small block. they are really simple, just a metal tray below the crank.
anyway thats for some race beast ka24e. the person that originally started this thread probably wants a streetable stup with maybe 5-7 psi from a t28, intercooled, but what kind of options do we have for manifolds? any stock stuff we can run flipped over, or does it have to be aftermarket? can it be reliable? anyting running 550cc's we can grab the injectors from?
Most WHP you will see on on a KA24de block engine with use of windage tray and scrapper is about 3 WHP on average. V8's typically show more HP simply because there are more cylinders and displacement is greater.
If you really want to make 10 WHP the best way to do it would to reduce bottom end pressure by adding a vacuum line to the bottom of the block inline to the PCV line, and use a crank scrapper and windage tray.
Or spend $5000 on a sub-par dry sump oil system, with combination of scrapper.
