Separating the Dry Sump Tanks
I was wonder if you could separate the two dry sump tanks and still maintain the proper function. I ask over at the C6 forum and thought somebody here might have already done it. It looks like the bottom plumbing can just be extended and refit and the top lines can also be extending.

I don't know much about dry sump oil systems, so I can't really be of much help, but I am still curious as to what you are doing. LS7 swap? Can't fit the tanks in the way they are now, and looking to make some clearance? There are some pretty smart dudes on this forum, who are really good at, well, for lack of a better term, let's just say, "fabrication", and leave it at that. I am sure someone will answer your question soon.

You have a 2009 or later LS7 tank there, that piggy back tank was added by GM because guys were running low on oil during high speed track sessions. The 2006-08 Z06s didn't have that auxiliary tank, if you think you will press your C3 that hard then yes, you could separate the 2 tanks, just make sure the small auxiliary tank is above the bottom of the main tank and still below the top of the main tank in it's new location. Or remove it and run the 8.5QT main tank alone or trade it to some early C6 Z06 owner for their smaller main tank.

Solid,
I will not be running it that hard. The build has taken many turns so far and I came across the LS3 with everything that was within the budget and uniqueness that we were looking for. Not to mention the fun. The main tank fits great in its location. I was wondering about function if I removed the secondary tank all together. I still have an alternate location for the secondary tank, but if I don't need it, I would rather not do the extra noodling.
Thanks

get a 2006-2008 tank and you should be fine, you should be able to swap with someone that wants the higher capacity tank easily. The older tank hel 8qts, the new one has 10.5qts. You only need the extra capacity for long left hand corners over 1g. (like holding it 4 seconds in the left hand at 1g!) -Dan

the bigger tank is all you will need, for racing you can make a larger capacity tank...you realize that the oil pan will still be carrying quite a lot of oil as the phrase 'Dry sump' is a misnomer...there best utilized to keep the oil cool ....If for no other reason than bragging rights a street driven engine is probably better served with a stock oil system

I have the earlier style of Corvette dry sump tank if you'd like to swap.
The larger tanks were only needed for cars that were setup for road racing with modified suspensions and race tires. For street use the smaller tank is fine.
