Ken, do you plan to run a trans brake?
Well everyone I know said that is the way to go. Right now I have so many things left to do, as you having built a turbo setup know, I will be happy to just get it up and running for now.
Ken
Hard to tell since I cant see, but are your turbos perfectly level, with the oil inlet and outlets at or near 90degrees perfect vertical.
Ken, I'm glad you are building this instead of me.
Some considerations I'll just throw out.
#1 - Hump hoses. Make sure you use them where you attached stuff to the motor that is attached to hard points on the frame.
#2 - hump hoses. On the pressure side, they will expand as boost increases and it pushes on the sides of the hose. So don't get things too tight. Also, have spares. It is this movement from pressure changes that wears them out, eventually leading to a leak.
To pick a reservoir size you should test your pluming and pump. Run the pump and dump the return water into a 5 gallon bucket and time how long it takes to fill the bucket (or some portion). That'll let you know how fast you can consume water. With the pump rating, you should be able to figure out what your system head pressure is. Then see if you can fix some things creating that head pressure.
With my AFCO dual pass heat exchanger and Spearco intercooler core, I was seeing temp increases of up to 40F from green light to win light on a 1/4 track. From coasting to picking up the time slip, ACT temps would drop back down to just below ambient temp (still some ice left).
Testing my pump showed it was moving around 1 gallon in 13 seconds. I had a 4 gallon system. I never got to test if I could move 2 gallons in the same time, what impact that would have on ACT. But I believe, I would have seen less ACT rise over the length of the run. So don't hesitate to benchmark some of your plumbing ahead of time. After you get some data logs going down the track you'll get some better ideas on what to do. But if you optimize your system now, maybe you won't see a need to change anything.
As for adding ice. The tank I had had about a 4" opening to add water/ice. And some of the bag ice you get has big chunks and I had to break them to get it in. At the track you'll go through lots of Ice. I went through 60 lbs and still ran out. It melts, and sitting in staging lanes uses it up pretty quick.
Ken,
I'm very impressed with how tightly you have been able to package everything. This is also the first time I can recall seeing someone using part of the supporting framework to feed exhaust to the turbos. In these pics it looks like the turbine housing is bolted to a matching flange that is welded to a short piece of square or rectangular tubing that is welded to the supporting structure, and exhaust from the motor is feed into the side of that square or rectangular tubing.
Is this something you have seen done on other STS remote mounts, or just something you are trying ?

Sound will be fine until the turbos spool up. That frequency of sound is higher pitched than automotive mufflers are designed to silence. Should sound cool.
Thought of something else that i was going to do, but never got around to. Adding a sacrificial anode to the intercoolers heat exchange system. You may want to add support for a screw in zinc anode into your reservoir tank. You can find them through some marine sites. They are available in a style where they screw on through a bung, and have a ground line you can attach. I used a meter with my system and didn't see any voltage being formed, but it was new then. As water works on the aluminum it can start a process of corrosion.
You will want to also be able to get the water out of the system as well as bleed air out of the system. That may require a bleed valve at the high point in the system, and a drain at a low point.
Air/liquid systems are a bit fiddly.
oh, and a note how fluid pumps work In series, they allow you to move more for a given head. In parallel they allow you to move the same flow but for a greater head. In series though they will never get higher than their max output at zero pressure. These pumps are typically centrifugal, not roots so they don't compound in series like a roots blower.
What that means is that if you have a pump rated for 6gpm and in your system head pressure causes it to be 4.5gpm, adding another pump in series could recover that 1.5gpm lost to head but it won't get you 9gpm. All approximate, but should give you an idea of what to do to achieve what you need.
here is a link to an anode that Flex-a-lite makes.
