Camaro LT5

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

I have been a fan of the GM controllers for most of my recent build for a few reasons. Refinement of calibration, and familiarity. The E67 used by the LS9 was used for a long time and was a very refined package. We have refined the 427 LS9 package for 10 years and over 30 engines. That package is sorted!

If the engine stays relatively stock the OE controllers work great with tools like HP Tuners. My buddy Dave Mikels tuned all this packages and continues to make them better.

I'm moving toward a hybrid set up on my LT5 do to the fact the GM ECMs will not do what I want to do. The aftermarket has made big gains in the last few years in refinement. I know as I move into a new control system we will have some learning curve. As a GM engineer I like things refined. Holes in an engine calibration bug me.
