Methanol Injection: What Are The True Performance Gains? (1 Viewer)

No I created my setup by piecing together all of the parts I specifically wanted. For no particular reason I just don't like the plastic hardline and in my setup since it is part of the intercooler tank if there was a leak or break in the line it would run the IC out of water. So I used -4AN for all of my hose, I spec'd inline filters before the pump and before the injector, etc.

But that is the setup I recommend for the guys running SC's that aren't measuring their post compressor IAT.



ScottRyana- Are you running the Snow Performance level 2 for the MAF/MAP?

Your Haltech will run your injection, right? Where did you source the pump though?
 
Correct I have setup my Haltech to trigger on IAT and boost pressure so it won't spray at idle if IAT gets high and conversely it won't spray at high boost if the IAT's are low.

I bought the pump from:

Water Alcohol Methanol Ethanol Injection Systems - Water Alcohol Methanol Ethanol Injection Systems

Almost all of the pumps that are "Made in the USA" are made by the same company and just badged with the different companies' names.

That pump looks identical to my snow pump, interesting.

Few questions!!!
If your running the meth/water injection from the intercooler tank , it has to be from a reserve tank right ?
Then also you would be running meth/water through your intercooler , not anti freeze ?
Sorry if I am just stating the obvious
How are you measuring the intake temps before & after?
 
Yep I have about a 5.5 gallon reservoir that has my intercooler pump, my water/meth injection pump and my windshield washer sprayer pump all hooked up to it. I run the -20f washer fluid which is around 70/30 water/meth.

I am just using two temp sensors into the Haltech for before and after temps.

Sorry for the noob question. Do I need methanol injection if I am running a WAIC setup?
 
It really depends on how good your water/meth setup is. Mine was not performing as well as I would have liked. I bought a huge new IC core to have a new IC built, when it was done it didn't fit under the hood, so next to rebuilding another IC, my next option was water/meth. In an ideal world you wouldn't need it, but it is pretty nice to have.

The only true way to know would be to install an IAT sensor after your IC to see what the IAT's actually are. If they are high that yeah water/meth would be a good idea. If they are pretty low even with high ambient temps and max boost you are fine.

Scottryana, couple of questions-
What is the minimum size SC pulley wheel you think we can get away with?
Where did you decide to position the meth injector spray within the intake?
Thanks!
 
I am not running a TRD Supercharger so I can't tell you what size pulley to use and no one has yet to produce any IAT's.

I know there is a 2.6" pulley....

Also injector placement is very personal. Some people do like it right before the throttle body to cool the cylinder as much as possible. Some people like it before the compressor as it cools the compressor and helps with efficiency. Some like it post intercooler since they worry about injecting liquid into the compressor or injecting meth into the thin aluminum intercooler, etc. There are lots of ideas on it. I do like mine before the throttle body but if you're using a 2.6 or 2.8" pulley and the compressor is way outside the efficiency range, pre compressor might not be bad.

With the TRD supercharger, injecting in front of the throttle body is going to also cool the supercharger as the throttle body is bolted to the charger. On mine, now that I have the methanol injection, my supercharger is only warm to the touch after driving it hard because the water/meth keeps it cool. It used to be so hot I couldn't touch it. This location was suggested to me by the tech at Snow Performance and he said not to worry about the intercooler. The nozzle I use is the smallest size (175 ml, IIRC ) so it won't cause pooling in the intercooler.

ahhhhh, I see what you mean now, I was thinking incorrectly they meant to install the nozzle right before the intake? I guess snow then reccomends that the methanol goes through the sc? do you have any pics of how yours is setup? I don't plan to do an intercooler but may run a 2.8 with the methanol instead. Do you think the snow performance system only would be sufficient?
 
No you are not thinking incorrectly, both are fine ways to do it. Before the SC'r is just a way to squeeze a little more performance out of a maxed out supercharger.

Mine is injecting in front of the throttle body. PSE saw no rotor issues at all after 113,000 miles of that type of use.
 
Just the one crappy picture is all I have of the nozzle. The other is my custom tank that mounts the injection pump and washer pump, not quite done with wiring and plumbing in the picture
