Drysump/Turbo

[Frederic Breitwieser]

>What about the dry sump for the turbos?

Personally, I think dry sump is the way to go for a variety of reasons -

1. Multiple pickups - you don't run dry on very hard acceleration (or hard
turns, depending where your pickup is)
2. You can pump other fluids - like tranny fluid.
3. Plumbing a turbo is very easy - no block drilling for return lines (pans
are easier to drill)
4. by having 2-3" less underneath your engine block (just enough to clear
the crank, since the oil storage is remote), you can lower your
engine/transmission for slightly lower center of gravity.
5. Easily serviced (parts are external - but then you have brackets and
belts to deal with)
6. Much more flow capability

Disadvantage 

1. its belt driven, not gear/chain driven - opportunity to break increases.
2. High cost (in the 800-1000 US dollars more or less)
3. OEM oil pumps are DIRT CHEAP. :)
