Here is a picture of my chargepipes with one pipe as boost and the other one for Meth

Also, for safety reasons, i did change my meth lines to braided.

The shop did this for me. I think they are custom made black braided lines.

Good question! I was thinking the same. One would think hot side will atomize better and offer cooling.
But, at the J pipe seems better if you're using methanol for fueling requirements and not just cooling and a bump in fueling. At the chargepipes It would seem like you lose much of the methanol for cooling and not as much for additional fueling requirements. (Those not running PI)

At the J pipe (cold side) you get a more direct shot into the combustion. Down side, the middle cylinders may get more methanol then the outers. Which is very possible. At the charge pipes (hot side) you would lose some of the methanol content simply from evaportation and cooling the hot side of the intercooler for example. So, although they are both sucking into the motor. You would evaporate some of that methanol before it reaches the combustion chamber. Is it a lot? I don't know exactly.. But, to my knowledge a lot of guys running dual nozzle at the charge pipes are using mostly for cooling. Someone correct me if I'm wrong. Many guys are spraying right into the J pipe and yes although the middle cylinders may get more methanol then the others. The motors seem to be happy and I see a lot of power being made. Direct port injection is ideal for even distribution of methanol into each cylinder. But, the downside is you get too many droplets and this setup is ideal for maximum cooling. Kind of like port injection. It would require your primary fueling to be dialed back because it could be too rich of a air fuel mixture. I think this setup is overkill for most people. I will run a few nozzles post intercooler for sure. Not sure where exactly but, J pipe is a good option. If it aint broke dont fix it. Just my 2 cents.

Any and every methanol injection system will tell you to install nozzles 6-12” from the throttle body post intercooler, which is the j-pipe on our platform. Sure you can install them on the I/c pipes pre intercooler, but you are not going to get maximal benefits from the methanol and you are essentially heating the meth injected air back up as it passes through the intercooler.
Spraying a fine mist of alcohol into a pipe with 20-30psi of airflow is going to mix and distribute pretty well, which is all we are looking for. Nobody should be running a tune so far on the ragged edge that a 5-10% variance in methanol per cylinder is going to hurt anything. Look at datalogs comparing 2 cars with methanol injection pre and post intercooler and I guarantee iats will be lower on the j-pipe injected car.

I had my 2 nozzles post intercooler on the intercooler itself. Resulted in uneven trims on bank 1 & 2
Moved the nozzles to charge pipe, bank trims a lot more even but IAT went up, which is what I expected. Moved the nozzles to j-pipe now and same result as post intercooler placement. Uneven bank trims on 1 & 2. IAT went down. My conclusion is charge pipe placement allows for best mixing of meth and air before entering the cylinders, but IAT not as effective pre-cooler placement. Will be putting nozzles back to charge pipes. |

Maybe have a high flow #6 in the charge pipe for best mixing, then maybe a small #2 or #3 in the J-Pipe to help lower IATs? That's how I'm setting mine up right now but with two #5s. |

Also to have only one charge pipe spraying meth, likely means its going to go thru only one side of the charge cooler, and out the cold side, possibly also having the same effect. anyway my tuner said he's seen the best results with placement at charge pipes (other than PI), so i'll follow that for now. slight increase in IAT can be negated by advancing timing from meth fueling. i think @f80paul has some experience here Last edited by E92inSG; 04-22-2020 at 11:21 PM.. |

Isn’t that strange.... Cary Jordan thinks differently..... J pipe is the way to go if no PI
I suppose the saga continues ... He also knows his stuff Maybe it’s down to how they tune and what they have experienced Either way both are good tuners so... go with whatever your tuner recommends and they will take care of the rest! |

honestly i think there're a lot more variables than simply nozzle location. The nozzle CC, type of spray, bung location in the J-pipe, 1 or 2 nozzles etc would prob all matter.
For my particular car, with dual ProMeth 755cc nozzles, the logs are clear and undeniable. The 2 bungs on my RK Tunes j-pipe are on either side of the pipe facing directly into each other. The 2 relatively large cc nozzles would have been spraying directly into each other. This could have been a factor as well. Maybe 1 nozzle or even staggered bung location might have been a better design, I don't know unless I try. For now I'll be going back to charge pipes placement |

Since Im trying to just run a proper 93 tune in CA, Im trying to go simplest meth setup and just the drop in charge pipes seem to be the easiest. Basic plan is bm3/pipes/meth, use j pipe as boost reference for controller.
Are there any good setups that are know to have a res that mounts nicely in the f80/82 trunk? |

I think Im going to take the advice above and do 2 nozzles and use jpipe as reference only. Ill be running the 93 map, thats the idea. Im not trying to go full custom, but spraying meth will easily let it run the stage 1 without correction.

My next meth configuration will be pre-IC strictly for cooling purposes only. Highly recommend going the PI route if supplemental fuel supply is needed. |
