Those who have the diverter, how do you like it? any noticeable changes? anyd power increase at all? im looking at them and im on both sides of the fence on this one. thanks

I think it helps divert air to the IC ....does its job ...Squirts water on it too !!!

 

That's gotta hurt!

Matt

 

haha.
how does the water sprayer work? does it come with a tank and pump etc? or does it hack into the window or headlight misters?

 

I would still love to know how the diverter and mister on the stock IC compare to Diverter and mister on the Alta IC. Anyone ever look at this?

 

i think some people hook it up to the line for the rear wiper. so that you still have function of you windsheild washers.

 

yeah i would probably hook it up to the rear sprayer...i dont recal ever needing to clean my rear window so badly i needed the sprayer.

 

Interesting question however.. is there any concern about spraying washerfluid on the IC? Here in the northeast, water doesn't cut it for washer fluid in the winter, and I'd be concerned about spraying regular (read chemical) washerfluid over the IC.

Any thoughts on this?? Please share experiences

 

I dont think washer fluid would hurt the IC?

 

To the best of my knowledge there is no factory option for a sprayer on an MCS. All the ones I have heard of and have seen on MCS's are aftermarket.

 

I bought the diverter and thought it well worth it. I also wired up the sprayer to it own reservoir and pump. The pump is wired into an RPM widnow switch and an arming switch in the passenger compartment. Turns on at 4k rpm and off at 6k rpm when armed. I put a 3 gallon tank in the trunk and ran a line from there to the front. I am still testing, but notice a considerable drop of air temp in the intake manifold, around 20 degrees.

 

So, .... you added 25 lbs to your car to make it faster?....

That's a lot of water being sprayed on your IC. I would be worried about shorting out the coil or plug wires.

 

Well, first is that you would use straight water instead washer fluid. Also, in winter you just don't need to mist your IC as it's as cold as it going to get, so just empty the tank or re-hookup your rear washer.

 

Personally I have found little performance gains, if any at all, while tracking my car and misting the IC with water.
But, back to the topic, I feel that the Alta diverter is an absolute must in improving your IC efficiency. It should be the first mod done unless you go with an aftermarket IC.

 

I notice a geographical bias in these answers: ChocolateAZ is in Arizona, while onasled is in Connecticut.

Makes sense that they would get different results...

 

thats a good idea. what sort of pump are you using? i have a one gallon cell i could use.
could you tell any performance gains?
what is your goal for your car? auto x etc?

 

If you are handy with making things, you can always make your own diverter out of sheet aluminum and angled aluminum!

i thought about that. but now that i live in these apt's i just dont have the resorces (saw grinder etc etc)

 

Exactly. Dry desert air makes a differrence.

I noticed that the air in the intake manifold was on average, 20 degrees cooler, with ambient temp of 67 degrees outside. I measured this using Digimoto OBD2 software, which allows me to record all of the sensors in the car and view them realtime. I ran some baselines and then turned on the sprayer and it took some time for it to cool down. While it deffinitely is a kick in butt like nitrous, it can't hurt. Also with the air diverter almost all of the water evaporates in the intercooler and none of the water can get sprayed as far as the coil pack.

I used a generic windshield washer pump from JC Whitney.

 

Believe it or not Washer fluid will help with cooling, It has alcahol inside.
I will be doing some of my good old cheater tricks at the track as soon as i get my MCS
Ill be doing a base run for MPH
then a run with Ice on the i/c/Intake pipes before the run
i have seen some GOOD MPH gains on turbo cars doing this. ESPECIALLY once the vehicle is staged take some liquid oxygen and spray down the FMIC its amazing what kinda times i have gotten. Heck one time i use a fire extinguisher to cool down the i/c :D

 

Be carefull with the window washer fluid, it's corrosive, hot aluminum doesen't like it much. On the plus side it will work better.....

 

I like the diverter but one thing I don't like about it is that the wiper will move when ever we want to spray the intercooler...

ChocolateAZ,
How can I connect a push button switch to the original wiper motor so that I can spray the IC w/o moving the wiper...

 

You are better off just getting a washer tank with motor and mounting it in the back for water to the IC. Adding another button directly to the washer motor would make you have to run seperate wire to the motor for it to just run the washer motor. It would be much easier to get a seperate tank and motor for that job. JC Wittney has a tank and motor for 20 bucks! The tank is not that big, but it will work!

That should be easy. Just find the wires going to the motor, and splice into them. It would be easier just to install a new motor and wire it up seperately though. You should still be able to sue the same reservoir if you want. It is much easier. Be warned however that the OEM reservoirs do have a limited capacity.

 

The benefit of adding a seperate tank and washer would not have you cut into the stock wires! Just a thought if you are worried about splicing into the factory wires! Besides you can add a bigger thank if you would like. Another thing is that you would have to use the same fluid as what you use for the front washers. So all you would get is just water! I would rather keep mine stock and just use a seperate unit. My 2 cents.
