Talked a little with the guys over there at cooling mist and they seem to think we could get upwards of a 10-15% increase in hp by installing one of their systems. I'll continue to prod around and will try to get in touch with devil's (another big name in w/i). Hopefully this could be a decent additional mod available to us, and a cheap one to boot!

looks neat. i don't understand what it does so i'll have to do some reading and also research about the warrenty issues since i'm in a new car.

 

It basically is a mixture or atomized water and methanol (usually 50/50) that is injected into the intake which cools the intake charge along with upping your octane level to about 100 (methanol I believe is ~ 116). Your computer should see this drop in temperature and advance timing, giving you more power. The methanol helps control detonation with the increased timing. This is also said to help clean your engine and prevent carbon hotspots from forming. It's worth a shot. Tons of people have been running this for many years. Read up on their site and you'll see for yourself.

i see a lot of the turbo motors using this setup, does the results show for n/a motors. my xfire is a limited model.

 

you will see results if you can crank up the timing advance while the water injection is active ... otherwise you are just lowering EGT temps and steam cleaning the engine ... not a bad thing.

installing a potentiometer on the intake air temp sensor with a relay that only uses the adjusted signal when the water injection is active is one way to achieve this ... i know there has been at least one SRT-6 owner that has done this as he is deep in the 12s ... for us N/A guys we're looking at a very small gain but good none the less.

 

Used that on my 2-stroke drag motors...but only after the 250 horse nitrous hit...as a cooldown function so the motor wouldn't coke itself float a ring and screw up a sleeve at the least.
At that extreme level on the dyno I saw 28 to 32 hp gain with the methanol wash down by itself...but that was not at 50/50.
Kind of wild at first the big hit and then you could actually feel the washdown hit...after awhile didn't notice the washdown and craved the big hit...that motor lasted 2 weeks.
Of course I put 15 hours on it and two bottles through it and a drag motor with no nitrous only lasts 50 hours. so it lasted as long as it should but damn that was expensive!

By the way the motor was close to 400 hp to start with.
And I am talking 2-stroke outboards.
So I really have no idea how that would do in a boat just chiming my experience with it,
Oh and now the shi**y part...after a spray of methanol or alcohol you have to disconnect the tank hook up a tank of fuel and activate the spray system to clean out all the methanol/alcohol or it will eat up all your parts.

K.K.

 

Intenseblu, would someone like yourself know how to make this timing advancing device? I myself wouldn't know where to start on that portion of the install, yet would like the additional hp versus an untuned car. In the 12's without even the pulley/ecu kit would be great, although the latter would be making their way on the car in the near future. Can we say high 11 sec Crossfire.

I know my SRT6 has a lot more poop when the engine has not really warmed up to it's normal operating temperature. I had even thought about changing out my antifreeze and trying a product called purple something that I had seen on the Speed Channel.

 

I know a product called "Water Wetter" is suppose to be a good additive for the cooling system. I also want to add a larger heat exchanger to help with cooling. I think I read somewhere that one from a cobra will work with a little modification, and it is quite a bit bigger.

 

Just keep an eye on pressure drop with a larger heat exchanger.

 

Correct me if I'm wrong, but we have a water to air heat exchanger not a air to air intercooler like a turbo car, so we won't have to worry about pressure drop. All you're doing is expanding the "radiator" for the supercharger so you can keep the heat in check. This enlarged heat exchanger would help prevent heat soak and a performance decrease on hard/multiple runs.

are you in an srt-6? or a na crossfire.

 

srt-6 roadster.

 

Using an air/water intercooler versus an air/air intercooler doesn't effect you having a supercharger or a turbo. These are not mutually exclusive situations.

Also, having an air/water intercooler doesn't exempt you from pressure drop. All you're doing is changing the heat exchange medium.

 

I know that these types of heat exchangers are not exclusive to each type of forced induction, I was just giving a general statement (i.e. a centrifugal supercharger will usually have an intercooler). As for our vehicles, Instead of directly cooling the intake charge, our heat exchange system is designed to keep the supercharger temps in check. By doing this, the intake charge will not heat up as much going through the supercharger, giving you a cooler intake charge. Enlarging the heat exchanger on the "radiator" side should have zero effect on pressure drop b/c there is no direct link between the two.

gotcha... my misinterpretation of what you were saying.

The Subaru WRX STi has this built in.

 

I want to put a couple of AC evaporators in the intake path in place of the air filters and put the filters on the forward intake opening. I wonder... hmmm...

 

Sti has an intercooler sprayer stock, correct? This is a lot different than a water/methanol injection... not comparable at all.
