ms6mil Dual Nozzle Meth Install w/ Throttle spacer

This is a write up I did a while ago on the dual meth setup... Just wanted to preserve the info....


Going to start off this thread with a list of what I'm working with. I have the Devil's Own DVC-30 kit. Originally came with the push to connect, but I opted for a clean and reliable SS Braided Line setup. This is also going to be for a dual nozzle setup. I will be including my experience with JMF Meth Throttle Body Spacer and the Damond Motorsports when it arrives.

First I am starting with the 2.25 gallon tank and will soon swap it out with something bigger depending on how quick I am having to refill the tank.



Made two 7/8 holes for the bulkhead fitting and the level sensor. I think I'm going to end up adding some epoxy or something similar to secure them to the tank a little better.



For the pump, I purchased the "Upper Housing Assembly" with the 3/8 FPT and swapped it with the pre-installed "push to connect"



For the Upper Housing on the pump I used one of the 3/8's to -4AN that came with the Devil's Own SS Kit and purchased the 90* from Jegs.com.



Next is the actual SS Line Set purchased from DO.


Now since I am doing a Dual Nozzle setup I needed more line. So I added an extra 14" line and an additional nozzle holder.


Also didn't like the t-fitting that DO sold so I purchased a NOS brand y-splitter. Probably not necessary but oh well...


At this point I am not quite sure how much line I will actually need so I purchased 4' of PTFE SS Line from Jegs.com. With that I also purchased 4 PTFE specific fittings. So once I measure everything out and get it ran in the car I will update with all the exact lengths of all the lines.



Next is this little guy I got today. This is JMF's version of the throttle spacer. It came with the 4 bolts and 3 plugs. Here is the configuration I plan to test out tomorrow. I'm not expecting an easy fit so we'll see how it goes. I also purchased DM version of the throttle spacer, so once they ship that I will add to the thread.



Here's a list of the things that I got to to work with so far. I probably went overboard but screw it.



I will update more tomorrow. Prices, links and more install pics...


Any recommendations or face palming are welcome.

UPDATE DAY 2


Started the day with running the main 15' line from the trunk into the down through the opening where the ITFP is. Drilled a 7/8 hole and stuffed a grommet to protect the line.



I ran the line down along side the rest of them. Worked out pretty good. After everything was in place I zip tied for added measure (not depicted).



The 15' line ended right at the fuse box. (Circled in red). Added the DO solenoid and the DO 8" line



Added the NOS Y-Splitter and made a 24" and a 28" line with the P.T.F.E. fittings and line I got from Jegs.com. You can see here that the NOS Y-Spliiter worked out better than the DO T-Splitter would have.



Now, on to the foreseen problem of getting the JMF throttle body spacer to fit with the stock Intake Manifold. I knew this was going to be an issue with fitment but I was determined to make something work.



This is the issue I found. The seam on the Mani and the uneven portion was preventing a good seal, as the DO nozzle holder was too bulky and hitting the portion of the mani circled in red.



My fix to this was to spend some time grinding the area down. Made everything nice and flush and with the help of a JBR Thermal Gasket, I had enough clearance to get everything in there after I flattened the DO nozzle holders on the grinder just a bit. Any nozzle holder similar in height but more narrow than the Devils Own rounded ones should work just fine.

If the JMF or even DM spacer was/is about 3-4mm wider, would solve the issue. Another potential fix which I believe DM is doing is adding an option for more throttle body gaskets with the spacer. I recommend anyone trying these on the stock Intake Manifold add two TIG's to the TB. There was plenty of bite left on the 4 bolts supplied to allow for the spacer and the TIG I have on my setup.



So everything but the controller is in and ready to go. I will wrap it up tomorrow with a test (vids & pics), then the tuning process begins. Adios e85!




Did some testing on the Dual DO7's with the JMF. Everything looks good. Leak Test, pump priming and functionality complete. Solenoid and the two check valves are doing their job. No drip coming from the nozzle. Going to finish up the electrical in a bit.



More to follow.....

UPDATE DAY 3

So I took yesterday off to pick up the motor for the upcoming build. I finished the install today. Because of my OCD and more specifically OCD in regards to electronics and wiring things in my car, it too longer than it really should have.

I ran the blue and yellow wires for the pump and level sensor along the side of the car under the door trim, and just found a spot in the trunk for ground to complete that portion of the job I just ran a red 16ga fused power to the battery.

For the controller I wasn't very creative so just put decided to put it into the change compartment.


The MAP inlet is said to require a 1/16th hose. First problem is I couldn't find one in town. I went to 3 autoparts stores with no luck. Second problem I found a cheap 1/16 hose at Lowes and its honestly too small and flimsy and I didn't feel comfortable pursuing that size. I ended up using 3/32 hose but as you can see it crimps and bend so easy, I think the 1/16th would have been worse.



I also purchased about 6 feet of 7/64 hose..

This is what I ended up doing



With the combination of Posi-taps and other wire crimping pieces I got everything wrapped up and put the car back together.

Priming it was tricky because of limited space everything being all connected and ready to go I ended up setting the controller to its lowest setting on the injection start and highest setting on the full injection dial. Then feathered the throttle while watching BATs and the green LED on the controller. Probably not the best way to do it but it worked. A little blind faith involved but it worked out.

I did find a leak so had to disconnect one of the lines at the Y-Splitter, applied some more thread sealer and tightened everything down. Re-primed and leak free.

Prices:

From Summit Racing...

$70.47
I ended up buying two 90* -4AN Female to Male fittings. Ordered the 2nd one from Jegs.com


Jegs.com

$65.94
X's 4

Devil's Own

$369 from Edge.





Because I didn't get the FPT Upper Assembly, and SS lines initially... Plus all the odds and ends It was a little pricey. Plus its a Dual Setup.

Total price without all the extra crap I bought....
$968.52... yeah... I know.

I took the car out for a quick test... I set the injection start at around 10psi and full at 18ish.. and grabbed a log. I still have e85 left in tank so I will do some work over the next few days..

Cool to see the BAT's drop from 90's to 50's and IDC's back down to double digits. The pucker factor was definitely high but I will be more responsible with the tuning moving forward.

Logs and failsafe install (pending delivery) coming soon...

UPDATE: 20 Oct 2014

Today I received the DM version of the throttle spacer. Here are a few pic's of what came in the box.

minus the nozzles obviously....

 

Great write up. Very detailed.

 

I haven't installed my meth kit and I know little so maybe this is a stupid question but why aren't you gravity feeding form the tank to the pump? I thought that puts extra strain on it and can cause the pump to fail sooner than later.

 

Had this discussion with the same thread in the other forum.... I used a sump and baffled 2.25 gal tank. I spoke with several people that have been runming meth to include manufactures from a couple of places... the strain on the pump, if any, would be minimal due to the short distance from tank outlet to pump inlet. The tank tap for the feed line was at the lowest point and had no issues from the pump or drawing in air. The pre drilled holes wouldn't allow me to rotate the pump upside down and still be flush with the bottom of the tank.

 

It looked like you wouldn't be able to flip the pump, but it is a very short distance. Just curious, and again I wasn't criticizin. Just hoping to learn a thing or two

Thanks for the information, I may have to do something similar with my AEM nozzle. Thing is huge

 

No worries... just being as thorough as I can be... I have been asked that several times...

 

Sick write up

 

I have a similar tank and had my pump mounted the same way per Devil's Own instructions. My pump failed after a few months, not sure the mounting had anything to do with it failing, others have had pump failures too, mounted flat. I decided to mount the new pump lower after a few people suggested that the pump has to work harder to pick up the fuel when mounted upside down. Now my pump intake is at the same height as the tank exit at the bottom of the 2:25 gallon tank.

 

Hi guys, it's too much to ask for pictures off the wiring setup? I'm planning to install my meth kit but the wiring setup seems to be kind of tricky

Thanks
