nifty little water setup there. Do you think it will have any flow issues merging to that single outlet? Maybe the shorter side trying to go faster or something?


I think it would be neat to put a temp sensor in each head to see if one would be cooler then the other. Like you said, the shorter one I would think would flow more then the longer hose. Might have to use restrictors to get it balanced.

Probably won't have any issues burning methanol, but it would be neat to see if there was/how much difference.

Got my CHI Intake - but it's a C base, not the W base model. May be mis-communication between CA and AUS about what exactly was in stock. Will see what they say next week. Can use it for sure if that's all that's available. Lucky to find even this.

Some CHI 9.2 intake views

The AFD heads place the intake about .500 high off the china walls.

You could probably make an aluminum spacer for the ends to fill up most of the gap, then use RTV for the rest.

That'd only work in the front, so might as well just do a plate. I already have .250 plate scrap left over from the motor plate, so a cover plate is a pretty easy make. The plate I used on the old motor worked well, worked better with made gaskets between it and the china walls. Then RTV down the head edges and it held very well. I drilled and tapped the bitty holes in the china wall - might have to punch a few into the Dart walls and use flat head countersunk screws. Some advantage to being able to just pull the intake to R&R port gaskets and not have to worry about sealing the intake ends.

From the LOL - Not Department: New update from Jegs on Milodon pan delivery date: 01/31/2022

Pretty sure I'll have the new F-350 before I have an oil pan.

I forgot the rear china wall was a different curvature. The plate sounds like the perfect way to solve it, and not something I would have thought of doing. LOL

What I did for the old motor. From 1/8 and had to add a stiffener to keep it sealed against the vacuum pump. Next one will be either 3/16 or 1/4. I should have enough 1/4 scrap.

That looks good.
1/4" should be more than stiff enough all by itself.

When you mentioned not having to seal the intake ends, that would be a nice bonus. When I pulled my intake to check the lifters, I didnt get the rear sealed up as good as it should be, and it's leaking a little. Since it wasn't leaking a lot, and I only had a couple of races left, I literally stuffed a rag down there around the oil pressure line, and used duct tape to hold it in place. I did that after I tried gooping it up more, which didnt work.

I had that problem last year, kept leaving a spot in the pit. Turned out it was coming out the back of the intake. Getting that back bead just right and not gooping up the valley with RTV is a trick LOL. With the plate, I actually had to make thin gaskets for the end rails to satisfy the vacuum pump. On top I just ran a bead down each side between the plate and the head. Sealed things up pretty good.
