Trunk mounted tank/pump W/M install

[SHO9987]

Hey everyone, thought I'd share some quick pics with you guys from my snow performance methanol install. 

Here's the final product starting in the trunk.  AEM in-line filter, anti siphon valve, tank, and pump.

Running the tubing and wiring through the back corner of the trunk.

View from rear passenger side where the tubing and wiring lead down into the paneling (removed).  I later went back and ran everything behind the seat belt instead of in front of it.

Wiring and tubing running along floor bored/paneling to the front passenger side of the car.

Pump controller mounted in glove box.

Drilled a hole under the front passenger paneling where the power wire, methanol tubing, and boost tubing for pump controller exit underneath the car.

Everything exiting underneath the car.

Methanol tubing ran up through the engine bay following the fuel lines (I believe).

Methanol nozzle/intake pipe.

I ran the boost tubing for the pump controller through the fender well.

Boost tubing spliced into the intake with a T connector.

I also ran wiring underneath the front dash to the driver side for a green LED indicating when the pump is activated and spraying; as well as an amber LED which will turn on when the methanol tank is low. 

Overall I was really pleased with the install. I trimmed and stream-lined all the wires and tubing before reinstalling the paneling. It looks like a completely stock SHO on the inside... unless you look into the glove box or trunk!!  ;D  It took me and my buddy all day Saturday and half of a Sunday to install.  Then began the tuning with Torrie.  After numerous data logs and having to the turn the pump pressure up (I'm guessing because it is mounted in the trunk and has a fair distance to pump) the car runs fantastic.  Having the tank and pump mounted in the trunk makes for easy refills as well as easy pump adjustments too! 

Tomorrow the H&R lowering springs are going in!!!

Nice-looking install, helpful pics too!  What kind of tubing did you use?  How much of a difference in pump pressure needed to get the intended result?  Would love to see a vid or two of how it runs, if you can

Nice install. I just got mine installed a week ago and am doing data logging right now with Torrie. I decided to do my pump behind the front bumper in order to minimize the length between the pump and nozzle. Also just used the windshield tank for Methanol (super easy to fill) and relocated the tank provided on the opposite side of the front bumper to store windshield washer fluid. I also relocated the pump for the windshield washer fluid and wiring/hoses. Pretty fun install though! Nice job!

Did you put the check valve somewhere close to the engine end? Wouldn't want to much of an air gap in the lines.

I used the 1/4" nylon tubing that came with the kit and bought a little extra since I mounted everything in the trunk.  I just turned the pump screw inwards until Torrie told me to stop lol, so I don't know the exact numbers for that.  I'll get a vid with me and my buddy's Evo hopefully this weekend.

That was the route I was originally going to go as well, however my buddy convinced me to go with the trunk mounted set up. Torrie will get her running awesome for ya!!

The instructions with the snow performance anti siphon valve specifically said to mount it between the methanol tank and pump. I was thinking the same thing you were, and was originally going to mount it in the engine bay right before the nozzle to minimize siphoning.  I think the key is the fact that it essentially creates a vacuum in methanol tubing... like putting your finger over the end of a straw with fluid in it, how it stays in the straw when you raise it out of your drink.  Whereas before, air would enter through the methanol tank as methanol is either pulled (by the negative vacuum in the intake) or pumped through the nozzle.  With the anti siphon valve in place, air cannot come in through the tank to replace the methanol that might be siphoned due to the negative vacuum of the intake. Only if the pump activates will the valve open and allow methanol to move out of the tubing.

Problem is methanol turns to vapor very easily, with the long line run and the heat in the engine bay the methanol in the line will expand pushing through the nozzle which will leave your hose with vapor in it. I doubt the little time it would take to push out the vapor is significant though.

Ahh, very good point.  I didn't think of that.  But yeah, it'd only be a small portion of the line in the engine bay that may have vapor.  I can't think of why else they say to mount it between the tank and pump though.

See if MDesign can rig up CF tubing covers for the methanol line
