Joe,
Is your ECU from "Atkins" ? If so will it support staged injectors like Tracy's EC2 ?

Yep, I’ve already got 2 injectors on the “hot side” but I have a complete heat shield that extends from the housing out to past the injectors with a lip on the inboard side to direct any fuel forward or aft well past the exhaust manifold.
Bobby Hughes has given me some good info on this that I’ll check into as well.
Thanx,

Joe,
The only downside I’m aware of is from the proximity to the red-hot exhaust manifold. Its better to have them on the cold side of the engine. With that said, I used these ports for my primary injectors. I’ll be installing a heat shield with a drain before first flight.

Ah – I didn’t know. My engine came from Atkins with them plugged.
Hmmmm – since I’ve taken so much grief for only having 2 injectors in my setup – I wonder if I could put a couple more injectors in those holes? What’s the downside of doing that?

Joe, Those are injector ports for the primary injectors.

Also, there are two of what I guess are EGR ports on the top side of the center housing. You’ve got tape over them in the pictures. Those can be plugged too. I’ve got a couple of aluminum slugs that fit down into them and then a plate on top using the bolt holes right above those ports to hold the plate down tight on the plugs.

Thanks Joe and Buly, I figured that should be enough, but thought it wise to check.

Same here, Bill. Intake manifold gasket covers the upper ones and exhaust plate & gasket cover the bottom ones.

Bill, I have blocked all of them. The intake ones were blocked by may homemade gasket, and the exhaustones were blocked by the metal exhaust gaskets.

The attached three pictures have me pointing to some EGR ports, and where they seem to connect to a point near the intake manifold. Do these need to be blocked off other than that provided by the exhaust flange and the intake flange having no opening in those locations? If so, what do people use?
