For those of you with Paxtons with Meth/Water Injection where are you installing the injector nozzle. Before our after the blower, and why?
 
its before the blower on the Roe? I think its gets sucked in and cools the AITs down, hence it replaces a intercooler.
 
After the blower on the Paxton. I put my nozzle on the elbow right before it goes into the throttle body and orientate the nozzle towards the intake. Sorry, no pic on my pc.

Question: Any reason why you installed after the blower rather than before?

The reason why I'm asking is because I called Paxton, and they told me before the blower. Its supposed to help with the atomization. But then I think to myself isn't water/meth a corrosive. Wouldn't it cause damage to the impler's longivity, and to the overall unit itself if it is?

It was per Sean Roes instructions. The meth will not have an effect if it's not able to pass through the intercooler hence why we need it after.

Why wouldn't the meth be able to pass through the intercooler? I mean air has to go through there?

This is even a better question: If the intercooler restricts the air that much wouldn't removing the intercooler and installing meth perform better then? The only thing we would need to is relocating the Bypass Valve/BOV.

Sorry, probably wrote that wrong.

I believe if you inject meth before the inter-cooler it will not pass Quick enough to the cylinders to help under boost. Ideally, you want the meth to get to the cylinders when its needed and not puddling up in the tubing.
 
Let me get this right... Sean was inferring that the meth would in fact would be used more as Octane boost rather than a chemical intercooler if injected after the blower, and vice versa before the blower?:dontknow:
 
Litemup,

I can't speak for Sean, hell he has forgotten more about these engines then I'll ever know.
 
In theory before the blower, but the paxton impeller seems a bit flimsy to me, if using on a screw, or roots style blower it makes more sense to put before the blower. Plus it would be a nightmare to install it in the manifold under neath the blower. All of the guys oround here with meth on a centrifugal, or turbo install after the blower directly in front of the throttle body, kinda where You would put a nitrous nozzle. Hope that helped.:dontknow:
 
This is from Sean's instructions:
"The water /methanol injection system is designed and intended to reduce the intake air temperature of the engine. This results in cooler combustion chamber component temperatures(increases reliability and safety of pistons) and gives the engine the ability to run increased ignition timing advance, higher boost and proper tuning, significant power increases are possible. "

I personally have never seen Meth get injected before the centrifugal S/C :dontknow:

What type of kit are you planning on running?

I kinda figured that it should be installed after the blower myself, but when I called Paxton and asked them they told me before the blower unit.

on reds truck we went after the blower and am 90% sure in front of the intercooler. i will have red pop in later just to make it 100% sure :D

Ok I know I'm knew here and haven't posted anything but questions but I may have a little bit of usefull info for you. I also have a 05 srt 10 that has a paxton kit on it and seeing how I haven't had it that long (about a month) I don't know everything there is to know about it. However I also have a 05 srt-4 with the mopar stage 3 turbo kit and other bolt ons. The stage 3 kit comes with a feature called high octane mode. It has a switch that you hit to enable it and a led let's you know its on. in order to run in high octane mode you need to run at least 110 octane. If not the increased timing that high octane mode makes will cause the motor to detonate wich causes the knock sensors to turn the high octane mode off and go into a limp mode wich is indicated by the led flashing and a big loss in power. If I haven't bored you to death yet here is were the meth injection and location of the nozzles comes in. A company called cooling mist developed a kit for the srt 4 that will hold high octane mode. This means it keeps the iat's cool while also giving you the octane boost needed (at least 110). It has a tank with two hoses that go to the engine bay. One hose and nozzle is located before the intercooler and the other after the intercooler before the throttle body. It also comes with a progresseive controller to fine tune with so you don't feel any bog or hesitation when the meth turns on. I've used this kit and it will hold the high octane mode on my srt-4 wich tells me it works and works well. I'm just mentioning all this because I see no reason it wouldn't work for the trucks other than needing to tweak the kit for bigger nozzles if needed. Not sure on the demand the big v10 on 7-10 pounds of boost would have over a 2.4 litre 4 on 25-28 pounds of boost. But I'm rather sure someone like Sean or Coolingmist could help with that. Sorry if this was long winded or isn't relavent just thought it might help.
 
got off the phone with pat and am now 100% sure it is after the blower in front of the intercooler and that when he talked to paxton they said to run it that way too.

By "In front of the intercooler" you mean before the charge goes in the intercooler or after the charge passes through the intercooler.
 
In front of intercooler IMO waste.

After the intercooler get as much as possible to the engine.

It is a chemical reaction cooler............ it doesn't cool by water touching the parts.... It cools in combustion. Me thinks.
