Best chargepipe for dual meth nozzles
Like most of you, my chargepipe was one of my first mods. I didn't think I would ever run methanol injection at that point but was talked into getting a single bung just in case. I picked up the ER pipe as I got a good price on it and I didn't find any negative reviews. The only issue I have with it is the way it lines up with my VRSF lower chargepipe and it only has one bung.
I think ideally I would pick up a VRSF pipe with two meth bungs which should fit better with their lower chargepipe. The problem is I cannot find any photos with the nozzle installed or reviews of people that checked their nozzle placement before installing the chargepipe. I also do not know where the nozzles are placed. I purchased Terry's Phoenix Racing chargepipe and the methanol nozzles sat so far back in the threading I couldn't even see them from inside the pipe. This makes me concerned about poor atomization if the spray hits the threads before entering into the pipe. After looking at the ER pipe and the placement being right next to each other I would like to look for other options. Also If I bought the ER pipe again I would be running into the same fitment issues. My questions... 1. What would you go with? 2. Where are the two meth bungs placed on the VRSF units? 3. Do the methanol nozzles stay recessed in the threading or sit flush with the VRSF pipe? In an ideal world the methanol nozzles would be 180 degrees apart, sit flush with the inside of the pipe, and have a transition like the picture below.

Have you done testing to conclude that the threads were too far inward and hitting the inner thread wall? You can run a simple test with just water.
Anyway, if you want a specific set up with your meth bung nozzles - the "IDEAL" way is staggered (90-120 Degrees) and about 2 inches apart from each other. 180 is ok too. If you insisted on this type of meth bung placement we can have one made for you through ER. It's a little above and beyond the normal though, thousands and thousand of guys run all the above mentioned charge pipes without a hitch with methanol. As far as fitment issues, perhaps you need to adjust your lower CP closer or further depending. Mixing and matching brands could potentially cause issues as tolerances can vary. The VRSF meth bung placement is in their picture: |

I like 180 but I prefer it staggered, I don't like seeing two nozzles hitting each other. Imagine 2 injectors smashing into each others patterns, that wouldn't be ideal. Now 180 staggered 2-3 inches apart I could see ok, I just have this thing about it going up against gravity on the bottom injector. In the real world it could be trivial (Especially since the air is pressurized from boost), I personally haven't tested it. That's why I like the 90-120 and staggered, should be as close to as ideal, apart from direct port methanol of course. Anyway, the custom meth bung option is not that big of a deal, they make pipes daily so it's a simple exchange of notes with them to move the meth bungs. As far as fitment, this would be the first I've heard of it but if anything I've learned in this industry, anything is possible. Would the ER pipe line up better without bolting it down on the bracket? I personally don't use that bracket. Let me know if you need any further help with anything. |
