I think I understand the basic concept of a dry-sump oiling system. There is no pool of oil for the crank to splash through, right?

Is there a dry sump oiling system for the LS2?

 

A dry sump ensures oiling under high g loads, it also allows the engine to sit lower in the car for lower Cg; the HP saved by keeping oil off the crank may be a wash as you have to use HP to drive a larger oil pump but I don't have any numbers for this. To get one for your LS2 call Katech and give them your Visa number.

 

I figured it wouldn't be cost effective for a street car. I'll let you know when I run out of engine mods, I've still got alot to go. Thanks for the help.

 

agreed, there is an offset but.....

also, check with folks like paw, summit, jegs, etc. for dry sump systems.

yes, this is on the to-do list.

 

Figure 7-10K to do a dry sump right.

that is why many ppl use Accu-sumps.

 

I thought the whole point was to ensure that the car is adequately lubricated during a road race -- i.e. repetitive high speed turns.

That's why the Z06 has a dry sump.

Unless you're a serious racer, why bother. If you are, just trade your car for a Z06 and get an LS7.

So I'm confused. The need for a dry sump implies WANTING a stiffer body. Race car-ish, right?

 

A dry sump oil system does four major things.

a. Keeps the oil off the rotating assembly. This results in a fairly large horsepower increase (about 35 hp on a 1000 hp engine). That is the primary reason you see dry sumps on all purpose built drag cars that compete in classes where maximum power is a requirement. Actually you can get the same power with an oil pan but the pan must be very deep and as such doesn't lend itself to any car that is trying to be low to the ground. The added power to run the scavenge and pressure sections of the oil pump is negligible compared to the horsepower gained. Actually the horsepower needed to run any oil pump is about negligible. They can all be easily turned at speed by a 1/2 horsepower drill as anyone who has ever pre oiled a new motor can attest to.

b. A dry sump system allows a much shallower oil pan which means the front end of the car can be lower if desired than with a conventional wet sump system. This is a big deal in road race or roundy round cars.

c. Pumping the oil back to the reservoir allows the air entrapped in the oil to be removed. In addition the larger amount of oil and recirculation back through the reservoir results in additional oil cooling. This provides better lubrication.

d. Since the oil is pumped back to the engine from a reservoir tank you can design the reservoir tank such that under all g loads experienced by the car the pick up tube in the tank is never uncovered. In a normal wet sump system it is very easy to uncover the pickup under hard acceleration, braking or high side loads. This results in pumping air into the oil galley which provides poor lubrication.

 

Dry Sumps or even Accu-sump ( wet sump) are not needed on normal street cars. Only race cars and other High performance cars.

You may need 2 or 3 depending on your credit limit......

 

Let me see if I have this straight a LS2 comes with a wet sump system ???

 

Sure it does ...

 

As said there is no need for a dry sump for most st/strip cars (esp with a small stroke), a good pan goes a long ways
The aftermarket will convince you your car needs a catch can, tow hook, big oil pump etc.

 

So am I!!!!!!!!!!!
