Camaro LT5

[Stielow]

Working on the dry sump tank science project. This gets hidden in the passenger fender in the cowl area.

We run -8 lines off the valve covers to a -10. That runs to the top of the dry sump tank. Then the dry sump tank vents through a Mann and Hummel Air oil separator. The 5/8 line coming off the air oil separator runs to the induction tube.

The tall cylinder mounted to the dry sump tank is the transmission expansion tank. I run the vent line off the trans to the bottom of that tank. During open track days I have seen the transmission push out fluid when it is hot. Makes a mess. So now we add an expansion tank. Fluid get hot gets pushed into tank then drains back into trans when it cools.

We duplicated that setup on a LT4 after seeing it on Gunner.....which way is the arrow pointing on the Mann Hummel separator?

Thanks for taking the time to post this. I know people like pictures, but the technical side of things is what interests me about anyone's build threads.

This...
The explanation behind is so appreciated. It helps those that aren't 'in the know' get a better idea of how things can be improved. Of course pics also help see details that push others builds to new & better levels of execution.

The reason the tank has the extra volume added is because the oil level has to be checked with a dip stick. To make the system less sensitive to oil level we add an extra 2 quarts to the system.

This is the 4th car we have done this modification to and it works great. The only big issue is if you have an issue with it to service it.

Now I pressure test all tanks and hoses prior to assembly. Save a lot of time to fix it before it is buried in a fender.

Ask him how he knows this.

How do you know this, Mark?!

Great stuff as always. I really enjoy learning and reading about the technical aspects of it too. Thanks for taking the time.

I had a dry sump tank leak on Hellfire. Had to pull the fender to fix it. Kinda of a bummer.

Hi Mark, I have a question regarding your choice of engine management.

I know you're an engineer for GM so I can see why you'd favor the factory ECM's, but have you ever considered something like a Holley Dominator or HP or even the new Terminator system for one of your builds?

Can you explain why you use the factory ECM?

I'm at a point in my build where I'm looking at this and I'm torn on what to do after seeing all the success you've had running factory ECM's. I was looking in to a Holley Dominator for my LS7 because I needed DBW control and wanted to keep 2 O2 sensors, which you can only run 1 with the Terminator. I think the Dominator would be overkill really for my setup with endless inputs and outputs that I'll never really use. I just think if it works for you, it must work for me.

Would just like your insight.

Thanks,

John

Regarding the induction tube attachment, understanding that Mann Hummel -10 line should be downstream of the MAF, have you found there to be an better attachment angle/arrangement? A "T" with the -10 hose connection at an angle to the airflow + away from the short radius bends? I'm finding a larger fresh air vent is needed to help keep the oil clean vs. the stock 3/8" lines.
