So I've finally gotten every thing in order for this build after almost 5months of research and planning. 4 nozzles total.
The goal of this build was to design a setup to attack the largest deficiencies of our 3.5 ecoboost transverse setup, via staggered methanol injection.
#1. Small stock turbos - why not use the cooling power of the methanol to cool the air charge at the source of heat - compression. Pre turbo meth injection cools the air charge allowing cooler discharge temps, via more efficient compression less compression losses cooler discharge temps. Pre-Turbo injection effectively extends the compressors boost map, making it behave like a larger turbo. Using a small 1gph high quality nozzle about 8inches up the intake tubing from the compressor wheel should allow me to exploit the benefits of wet compression without worrying about wheel erosion.
#2. Intake manifold distribution/Methanol atomization.
One of the other design factors for this setup is methanol atomization. The supplied nozzle (15gph)with the alky kit is good, but 15gph divided among 2 or more nozzles will lead to better atomization and ultimately better distribution in our intake manifold. Take into consideration that our intake manifolds dont distribute meth evenly due to that 45° bend after the throttle body forcing the charge air to change direction. The larger droplets of meth have more mass than the air, causing them to travel in a straig line, and end up riding the manifold wall; traveling to the rearmost cylinders intake runners. This causes the rear (right bank) of cylinders to receive more meth than the front (left) bank. This can lead to compromises with tuning (direct port solves these). By utilizing more nozzles with more precise orifices, we can inject a finer mist which will distribute more evenly to the cylinders for combustion chamber cooling, thus a higher total level of knock reduction. So here at the throttle body, I have a 7gph nozzle, which is approximately half of my total system potential.
#3 Intercooler efficiency -
Our intercoolers are not as efficient as say the f150, fusion, and definitely not like a focus RS. So another nozzle right at the intercooler exit pipe should cool the air charge further. Since the piping to the throttle body is short, (about 12 inches) we should see some of the meth mist at this injection point make it into the intake and to the cylinders for combustion chamber cooling (major knock reduction zone). I have a 5gph nozzle here at the intercooler exit.
Total system methanol injection nozzle volume remains equal to the single nozzle included in the kit. In theory, tuning should be similar. Not exact...but similar. I will have Lms dyno tune after I prove the system out.
Now, on to the specs and parts list
14.97gph total (944ml/hr @100psi)
4 devils own nozzles
D01 1gph pre turbo(s)
D05 5gph post intercooler
D07 7gph nozzle pre throttle body (updated)
2 devils own check valves (soon to be 4)
Devils own nozzle holders
3 y fittings
All stainless steel braided line
Devils own 2.5 gal tank
Devils own bulkhead fitting
Lms Alky methanol Kit
Various fittings for re-terminating braided stainless to correct lengths/angles.
