Dry sumps

[toughnut]

I've just bought a new engine block to build up for my truck and it has fittings to run a dry sump if I want to. (Or turbo feed lines) haha. Anyway. I know the theory behind the dry sumps and they are great for flat track racing etc. What I want to know though is:

Are they good for what we do?

Are they good for extreme angles?

Can someone explain the difference between say a 4 stage pump and a 5 or 6 stage pump?

Cheers

I have had experience with them in oval track and they are great, i believe they would suit off road racing very well but it is normally a expensive thing to set up and as most people would prefer to sink the extra money else where like suspension.

They are a dear setup - hence they are not done too often. On a LS they run at about $6k, although the ls7 has one factory.

Even then the ls7 isn't a true dry sump.

There's a recent thread on Pirate that's pretty good on this topic.

yeah. There are a few 'new old stock' pumps around that can be had for only $1200. About the same for the sump and then the tank and cooler plus running the lines and brackets etc. From my reckoning it would cost around 4k for a decent setup. From what I can gather the extra stages are basically for extra scavenge points. Is that correct? then you have the main stage that pumps the oil through the cooler and tank then from the tank to the engine.

Rear sumps for the engine I have are not so common and I have to replace the one I have anyway so I started down this route. I know the expense, just trying to find out if the benefits are worth it and mostly if they are reliable as well.
