how much can the engine be lowered in the cradle?
how much extra oil capacity is there?
how far away can the oil resevoir be from the motor? back of the car?
how much, if any, power is free'd up or lost compared to wet sump oiling?
is there any significance to 4 vs 5 vs 4.5 vs 3 vein pumps?

my research is only turning up general information about the pumps and pans for the most part, looking for actual application info.

-Thanks

how much can the engine be lowered in the cradle?
Approx 6 inches, basically minus the sumped part of the pan.

how much extra oil capacity is there?
Depends on what size resivoir you use.

how much, if any, power is free'd up or lost compared to wet sump oiling?
The average dry sump set-up has the ability to scavenge 2 to 4 times the volume that it pumps into the engine. This causes negative crankcase pressure, which gives you horsepower. Dry sump systems also offer a more stable supply of oil in all conditions since there isn’t a rapidly spinning crankshaft located right above the oil.

The negative pressure is similar to that of a vaccuum pump, so net gain can be from 10-20 hp. However you will have much cooler oil than a wet sump.
