scott,

where exactly is your nozzle/s located?

sdminus

The nozzles are located at pressnt. Just after the intercooler and just before the throttle body in the elbow. I hoped this all being down stream would have given me even distribution.



I am now changing to push fit connectors. I am also gonna up my meth flow from 348cc/1 or 5.5GPH to 505cc/1 or 8 GPH. My egts are very low (around the 770deg C mark) and the plugs still look quite dark.



I also had a problem with the injectors going gummy and messing up the spray pattern. I know of a couple of other guys that also had the same problem using differant jets, so it seems to be a universal problem.

so you run 2 nozzles...



they are located in a Greddy elbow?



where on the elbow? are they on the top and bottom? are they on both sides of the elbow? are they across from each other or staggered?



based on your experience as to the picture you posted i am going to bias the location of my nozzles so they both aim a bit towards the inside of the elbow turn. that may help front to rear distribution.



your nozzles are getting gummed up? that's really bad as it may impede the flow. that is not a universal experience. it is most likely either the nozzles ( what brand and size) or the alcohol or the pump pressure. i will ask Julio for you...



good luck and keep us updated.

I really wanna change to the aquamist nozzels. They have a very good spray pattern.



I have a really poor pic of the lay out. Im going to alter it while the car is off the road. ( smashed lsd )



I have some cool power graphs that i can share if you like. I have the untuned meth and then tuned meth graph.



The Meth i use is the very best i can get. I buy it from the place that supplies the top fuel cars.

The first nozel is in the intercooler coupler after the IC. The second is in the elbow.



The nozzels are coolingmist m5 and m0.5. i have also seen this with the snow performance ones

based on your experience as to flow pattern i just located my 2 nozzles. since the secondaries are larger and located on top of the primaries and i wanted to go for a bias towards the front rotor due to the elbow turn i located my 2 nozzles as follows:



in the silicone coupler just in front of the elbow.

looking back towards the mouth of the tube i mounted one at 4 and one at 6 o'clock.



i leave for a week so will report in upon return.

The problem has got to related to the shape of the elbow. Im ok at the mo becasue i have richer injectors in my front rotor but it will come to a point. I will re post the pic on here so people know what we are talking about.



I think the only answer to this will be 2 jets of the same type above each runner on the elbow. I know it has to flash over but the thing with meth is. It will change state/ atomise when it comes in contact with a surface above 11 deg C. it has a 40 odd degC boling point and once it changes state ( ie from a liquid in to a gas ) it is imposible for it to turn back to a liquid. We have tried pre turbo methanol, This made up a whole AFR with only 31 cc/1 of methanol on SU carb elford turbo FB. My next project will be pre turbo meth or may be a hybrid mix.



I have a motorway cruse log in 11 deg C ambiant air that shows the IAT drop to -13 deg C after boost.



It is important for all to share info on this because it is a black art. Methanol will not give you instant HP but it yeilds more tq and the tuning capabilties are huge.

Providing the aquamist jets are meth friendly i am going to swap to there jets this week. I am still gonna run 2 jets but i am gonna re position them. I am not sure quite where yet. I am thinking in the elbow but on top and one per secondary runner

huh, interesting stuff guys. There is quite a bit of information in here that I have not heard before.



A couple questions though...



1. What injectors are the "best"?



2. Has anyone tried the probe adapters for the silicone couplers? They puncture the silicone coupler and allow for a probe, possibly and injector to sit in the IC pipe.

Just to add a small amount of information that may be relevant. The lower the temperature at which the liquid used turns to gas, the easier it will be to keep it in suspension in the intake manifold. We all know what temperature water is a gas above. This also assumes at sea level pressures. What about ethanol or methanol at sea level pressures? It doesn't take much to find out how this changes with various pressures.



Water: 212*

Ethanol: 172*

Methanol: 147*



See why water pools easier in the intake manifold than the other 2?

sdminus

I addition to that . Methanol changes state when it comes into contact with oblects above 11 deg C. It has a very low flash over and once it changes state it will not change back again.
