Jim,
I'm installing a turbo which means lotsa oil lines outside the engine anyway.
This engineering stuff is something I'm pretty good at. Whatever
modifications I decide to do will be an improvement over the original. I
don't do anything half-assed. I'm also kinda in a unique position fabricating
all the oil lines and such because I have access to all the best seamless
swedish SS tubing as well as every SS flare/compression fitting imaginable
and all the 5,000 PSI braided hose I could ever need. I'm not gonna worry
about springing an oil leak at 60 PSI on this little 270.
The only real problem I can forsee might be the cam lobes not getting
sufficent lube because the crank won't be splashing near as much oil around.
I'm thinking I might be able to fix this by not lining the pan with catch
screen. The 270's gonna top out at 3500, so a catch screen might not be that
necessary. Might even have to put the scavenging pickup(s) a little above the
bottom to allow for some oil to stay in the pan for the crank to splash,
especially at low RPM's.
The thing I really love about the dry sump systems is the external tank. I
can have a 20 quart oil capacity. It'll cost me 80 bucks an oil change with
synthetic though and I'll prolly have to put a heating element in the tank
for winter driving.
