Water/Meth Injection Nozzle Placement Question???
Ok, so I recently received my Snow water/meth injection system. It's all installed, and here's the main problem I ran into...
I'm running a maxed out A-Trim Vortech on my new all forged 396 low-comp engine. The intake system is setup as a MAF Blow-through. In order to accommodate the MAF in a near stock location, I trimmed the Vortech aluminum elbow down a few inches. (approx. all the way to where the vertical splitter resides inside the elbow.) This is the problem, with this setup I cannot place a single nozzle vertical (in order to spray equally into each side of the vortech elbow) due to not enough hood clearance. The Snow nozzle housing/elbow is quite tall.
So, question...if the nozzle is positioned so as to bias only one side of the intake elbow, will it be disproportionately distributed to the cylinders on that side of the engine? Or will it adequately be mixed up inside the intake manifold?
The ONLY place I figure I could theoretically place a single nozzle where my intake tract is not split, is before the MAF...thereby, hosing the maf sensor. Something I imagine is a horrible idea.
Maf sensor has a splitter, Vortech Elbow is split entire length, and there's an airfoil in my Throttle Body.
I realize the best fix for this is to purchase a splitter, and a second matching nozzle from Snow, and simply inject on both sides of the intake elbow. I will do this eventually...but want to get this single nozzle up and running before hand. I am going on another road trip this coming Monday.
BTW: I am now running a 625ml/min nozzle. I was running the 375ml/min nozzle, had it spraying 100% w/150psi pump at 2 lbs of boost...and it appeared I needed more.

In my post that "didn't appear" I stated I thought it would be possible to actually drill out a portion of the splitter the width of the nozzle...however, I'm not positive on hood clearance. Soon as I get the tranny rebuilt (hopefully within 2 weeks) I will re-tackle this issue.
