I decided to create this thread to merge opinions that are all over the place. There have been several arguments of where the nozzle should be placed but it would we beneficialy if we could get the opinions gathered now that we have a many more people running methanol.
So what is the best place and why?

[GreenPlease]

I'm curious to hear if anyone has thoughts on meth injection pre-compressor.

Please don't take this the wrong way, but this is a waste of a thread. The elbow camp will argue better cooling far away. The TB camp will argue more octane and better combustion efficiency.

As long as it is not before the turbos then I think any where would be fine considering that methanol is extremely corrosive

[Kevin@AKMotorwerk]

there really is no clear answer, i spoke to people at snow, they said it barely matters because they have dont plenty of testing and didnt notice any major gain or loss

that being said shiv and terry did testing and found the elbow that comes up from the intercooler and goes to the charge pipe is best.

for me the closer to the throttle body you are, the better the octane boost, the farther away the more atomization and intake charge cooling, but with less octane benifit, but i have no proof or tests to back that up

The thing is my TB location is showing identical cooling to the elbow location, so why would you sacrifice octane benefits for the elbow. I think the elbow is being used because it is a cheaper solution.

It would be nice to see some pics if anyone has. I am tending for the octane benefits especially since my install primarily as a octane booster. I see a far greater benefit when going race fuel than I did when I installed the cooler.

I have mine on the elbow and I see Iat drop as much as 23 degrees, but to compensate the octane, i raised the meth/water mixture to 66/34~

i agree, obviously you have seen more data logging, i have no had the chance to yet, but i do wonder about the long term affects of the nozzle in the rubber elbow too.

if the boost is strong enough to blow the stock charge pipe off the throttle body on peoples cars, i can only imagine what the boost pressure is doing to the rubber with the nozzle in it

If the elbow is your choice, I think it is worth just buying the elbow hard pipe with the meth bungs. It is safer and still only about $120 or so.

yea ar design sells nice ones.

STETT has one as well and they are both inexpensive.

I'll be putting it on my elbow pre throttle body on my M3....I want the octane as high as possible

Don't forget matt that you want it to mix well too. I guess one would say atomize better, not unless you are going to run 100% methanol.

+1 With my nozzles at the TB I was seeing instant 20+ degrees drop.

Does anyone think IAT readings may be compromised or affected, if meth nozzles are placed too close to the Tmap sensor ??

Having run this for a long time, I can tell you the IATs are spot on. If the TMAP was compromised, then when you got off the throttle and methanol then the IATs would be very sluggish or erratic. It is neither on my setup and I have been monitoring realtime IATs for months now.

[cn555ic]

My UR intake is doing a great job at keeping the IAT at bay...after an hour on the highway, the IAT temps coming off the highway was 70 degrees (ambient temps outside was 46 degrees)....Got off the highway and decided to turn on the meth to see where the IATs would go and it dropped to 51~....thats simply amazing on a fully warmed engine!!! lol I have the nozzle near the elbow and the meth/water 66/34~

You intercooler will have more to do with IATs at highway speeds than anything else according to the testing I did. The CAI really helped under WOT more than anything else.
