drysump Oiling Vs Wetsump w/ Accusump
drysump Oiling Vs Wetsump w/ Accusump Im trying to see the pros and cons of each:
Drysump
wetsump/accusump
wetsump/ 2 accusumps
can an accusump really replace a drysump when the only real concern is oil starvation? Already have a vacuum pump for the rings
as far as i can tell this are the pros and cons of each please feel free to add.
Drysump:
Pros:
little to no parasitic loss from crank moving through oil
adjustable oil pressure
more availalbe oi
if sized correctly can pull vacuum to seal rings
added ground clerance
Cons:
takes up a lot of room for pump and tanks
COST
Not Legal in all Classes
Accusump:
Pros:
Added 3 extra quarts oil protection ( 6 quarts if 2 are used)
compact in size
1/10 the price of Drysump system
Only need to plum 1 feed line
ability to pre oil the system
No class restrictions
Cons:
No vacuum for crank case if used alone
Crank still has to move through oil
Drysump
wetsump/accusump
wetsump/ 2 accusumps

I am worried about oil starvation on my engine at sustained high rpms (6000 +) while doing a standing mile race. Would the Accusump help me?? I really want a larger volume of oil available to me without adding extra to the pan and inducing more windage and aeration. Sorry to jack your thread, but I think I am asking roughly the same question.

I'm making the jump to the ARE drysump.
I needed drysump after seeing wetsump and high lateral acceleration leading to roasted bearings in similar cars.
For a standing mile, accusump should be more than sufficient. I can't see why you'd need the drysump setup unless the oil drag became a serious issue. Just keep an eye on your oil pressure.
The pro/con of each sounds about right. Depending on the car/goal, dry sump can lower the engine's center of mass closer to the ground.

I'm running a Canton road racing pan and 3-qt Accusump combo, and I think it hits the 90/10 rule pretty good - 90% as effective as a dry sump for 10% of the price. The Canton pan has a crank scraper, windage screen and 5 trap doors for multi-directional oil control. I couldn't justify the expense of a dry sump setup for the payoff.

After doing some reading about the accusump I'm planning to use that on my Camaro's new combo.

Have you taken a look at Aviaid Oil Systems? www.aviaid.com. That is what I am leaning toward. I have a vacuumn pump already, but what I really want is to get away from whipping air into the oil. The stroke that I have is 4.1 so my problem is too much oil and too much metal in the same place. I am using a Canton pan and it can be moded for a drysump system. I really do like your comments on pros and cons of both set ups for dry and wet. The accusump system is great if you don`t have windage problems to begin with. I have learned the hard way, vacuum pumps deal with ring sealing but really didn't help my windage problem. My only other thought is that GM has gone to dry sumps on their Z06's and for good reason. This is a good thread,hope you don`t mind me jumping in and sharing what I have experienced.

Verdad Gallardo Those Aviaid systems are pretty cool and they have a lot of different mounting options. I like that as all the other dry sump setups I've seen usually mount where the ac is.

Have the old 1st gen Aviaid on my slow car engine. Nice system, except the damn o-ring is so tiny & fragile between stages. Haven't seen their next gen yet. John is a good tech/sales guy. Usually has the tech line sent to his cell phone on w/e's, which comes in handy.

On a technical note I always see dry sumps advertised as stages. Such as a three, two, four, etc stage pump. Anyone want to explain that for me?
+1, I've always wanted a dry sump setup for my Formula, but never saw one that maintained the ac. Now... I just have to add it to the list of things to buy.

Two stage...one sump (suck the oil out of the engine & put it in the tank) stage, one pressure stage.
Three stage...adds another sump or scavenge stage.
Four stage...you get the idea.
