Snow Performance Stage 3 DI Install Notes

[Bull Run]

I tried fitting the tank in the position shown in the first picture, but it’s too tight and it fits too closely to the timing cover and belts. It seems to me that the only alternative is to fit both the tank and the pump in the trunk. My concern is that I will have to pull all those wires and lines all the way to the engine bay and I don’t see how I can do this, lol! I mean, I will have a professional do it but still...

I routed the wires the same way Adam did in the video below in 15:22. I recommend not using the same grounding point he did as I had random issues until I used another point.

I decided to install the tank and the pump in the engine bay, like Ron described above.

@ronemca @Bull Run what’s the “accurate boost source” described in step 2 in the instructions below (red arrows) where you connected the other end of the black silicon boost hose?

Also where did you connect the red wire of the controller? Did you tap into a switched fuse in the fuse box and if yes, which one?

 

[ronemca]

Snow provides a (B)oost (R)eference (A)dapter that gets instsalled in place of the factory vac fitting just behind the TB. That component provides three attachment ports for vac lines (one pre-plugged from the SP factory IIRC) It is ideal to connect your vac line to this.

It took me awhile to locate a switched source of under-hood power in the BJB, but I did find one. OTTOMY I don't recall the fuse number, but I'll send you a pic later.

So is it absolutely necessary to buy this Boost Reference Adapter (or a throttle body spacer) in order to get access to an "accurate boost source"? Isn't there any other place where I can connect the black silicon hose that comes from the controller?

 

[ronemca]

I am not sufficiently knowledgeable in this specific area to answer that question. I’m sorry. But - fwiw - the BRA is super-simple to affix...and provides you with a spare vac source for future expansion. (Boost gauge & WGA for example)

 

[MakStang]

Alternatively I suppose that I can use a throttle body spacer with a vacuum/boost reference port, such as the one below:

@ronemca by the way, do you have a link where I can buy this BRA from? I couldn't find one on Snow's website, I think the only one available is the Turbosmart one.

The TUNE+ kit came with a TB spacer with two ports (which I kept). I used one of the ports for the boost reference source. The other port can be used for a nozzle if you're not spraying into the charge pipe.

TB spacer that came with the TUNE+ kit: https://www.full-race.com/store/eco...oboost-throttle-body-spacer-with-boost-ports/

They also have an adapter for the MAP sensor to add a boost reference source there. I'd gone this route had I known about it, but I already trimmed the charge pipe to accommodate the TB spacer.

@Bull Run thank you. I ended up buying the Torque Solution TB spacer from a friend of mine:

https://www.unleashedtuning.com/torque-solution-tb-spacer-2015-ford-mustang-ecoboost-black/

This one also has two ports, so I will use one of them for the boost reference source. I will not use the other port, as I am going to spray directly into the charge pipe.

The only thing that I am missing (it is not included in the TB spacer kit) is the barbed fitting that has to be fitted on the port that will be used for the boost reference source, where the rubber hose coming from the controller will be connected (in red circle below). Anyone knows where I can find one of those fittings?

According to their website this BRA is for the 2013-2016 F150 3.5L EcoBoost. Does this fit our cars as well?

I got the kit used and it only came with one flimsy plastic barbed fitting that I replace with a brass one that I got from a local auto parts store. I think the threading was 3/8" NTP, but take the vacuum hose and one of the nozzles with you to compare the barb size and threading.

Sorry, this is the one for the EB Mustang: https://www.rallysportdirect.com/pa...ers/ummp00001b-cp-e-turbo-maptap-boost-source

I would get the BRA adapter from Turbosmart, I would not use the MAP BRA it has been reported to leak and cause issues with the MAP sensor. I am not sure if the CPE one is a rebrand or anything but I know turbosmart stopped providing them for that reason.

Looks like CP-e did change their BRA adapter:

[ronemca]

Yes - I’m sorry - I made an error. The BRA to which I referred was indeed from TurboSmart, and came with my 10# WGA. Sorry for that mix-up! It’s a nice little device; easy to install and allows for future expansion (like...oh...a vac-driven WGA maybe!)

Just a quick update on the install:

1. The pump's still fine being mounted on top of the underbody cover. One afterthought is that I should've used a pair of quick disconnect connections for the power wires going to the pump so I can easily disconnect the pump if I need to remove the cover. I left some slack in the wires so I'll cut them and install new connections the next time I need to remove the cover.

2. Rerouted passenger size brake ducting's still in place. I'll reroute the drive's side to match the next time I take the bumper cover off.

3. Zero leaks from the installed fitting on the windshield washer bottle.

4. Purposely ran the fluid low enough to trigger the failsafe on hard stops. The warning light still works and the boost control solenoid gets disabled as confirmed by a code being stored and boost being limited to ~17 psi.

5. The default setting injected too much too soon, so I backed off until I started to see a noticeable increase in the knock counts and negative ignition corrections as monitored on the Cobb. Decreased the injection start point a little bit to see how it'll do as the temperature's starting to warm up.
