water/alcohol injection?

[moltenice]

i was just wondering if anyone is running a water injection setup with their turbo'd Celica... It seems like it would be highly effective in a celica and would probably yeild high gains. Just curious to see the responses and possibly a discussion.

If anyone has been pricing them what are you seeing the go for? I know someone who puts together kits with a digital progressive controller and all that other jazz for $250.....

I was just in the middle of reading about this....

Thinking of getting it myself. I like to do a little research before I ask the group anything.

If you are interested in getting a kit, you should look into Devilsown. None of the other kits out there compare to it. Check it out www.DevilsOwnOnline.com
He include a digital progressive controller in hit kit instead of the traditional boost activated switches. So instead of (single stage) having the water come on at 5psi, you can have it start stepping up gradually as boost raises. not to many people know of his kits but they are awesome and very complete. Not to mention he is very easy to get in contact with regarding any questions...


Controller Info
"General Operation:
http://devilsownonline.com/cart/images/alc8.jpg
On power up the unit will blink the yellow led indicating what BAR setting the unit is setup for.
2 blinks is 2 BAR
3 blinks is 3 BAR

Then the unit will read the dial settings and calculate the slope of the progressive control.

Map voltage is read and converted to a boost value
Pump duty cycle is calculated based on dial settings and slope

When boost PSI reaches the START setting the pump will come on with a 15% duty cycle
It will ramp up to 100% as boost approaches FULL setting.
The pump voltage percentage will increase with a 0.2 pound increase in boost.
This means the voltage will step up 5 times over an increase of 1 PSI making a very linear response curve

For ease of adjustment, each dial has 21 settings that are incremental
There is a setting for every hash mark and another setting inbetween each
Having the arrow close to a setting will provide the exact setting.

For example the 12 o'clock position on the START dial of a 2 BAR unit is a PSI setting of 7
It will also be a 7 if the arrow is 6 degrees to right (or left) of 12 o'clock
once it is beyond half way to the middle the setting will be 7.5PSI
This allows the user to easily set the unit to exact values without having to be fussy with the dial

For reference the Dial settings for each version are as follows:
If the FULL setting is set to a lower PSI than the START setting, the start setting will be ignored and the pump will switch on to 100% when PSI is above FULL setting and will switch off when it is below the FULL setting.


In order to prevent loading down the MAP sensor signal, the voltage input to the controller is left floating. This means that tapping into the stock MAP sensor that is connected to your cars computer will not effect the MAP voltage.

However, if the MAP input wire (green) is left disconnected, sampled voltage will be erratic and therefor pump output voltage will be erratic.

LEDs:

RED - power led - It will be illuminated anytime there is power applied to the pink wire and the black wire is grounded.

GREEN - This led will light up proportional to pump output voltage, it will turn on dim and brighten as the pump reaches 100%

YELLOW - This is the FULL/Diagnostic led
It will blink the BAR value that the unit is set for on startup. 2 for 2 BAR and 3 for 3 BAR.

It will come on solid in normal operation when the output voltage to pump is at 100%.
It will stay on until output drops below 95%
This prevents the light from fluttering if the boost is hovering around FULL.

It will blink a steady rate when the unit is faulted.

Fault:
The controller will go into fault mode if
- excessive current draw
- fault in the pump circuit
- controller overheat
- pump wired incorrectly

In fault mode, the controller will shut off the output to the pump and will flash the yellow (FULL/Diagnotic) led.

The controller must be powered down and the fault condition must no longer exist before the controller will resume normal operation.

Open circuit conditions are not monitored by this controller
This is because many alcohol/water injection pumps have a pressure switch to modulate max pressure. During normal operation the switch will open and close. When the switch is open, no current will flow to the pump. Therefore, it can be normal for a zero current condition when the controller is telling the pump to run."

Well, I guess you did do some research on this before asking about it. Looks like a great kit.

I'm still trying to figure out if I need this. I have a very large intercooler, aluminum radiator and an aluminum oil pan.

[moltenice]

it would still help you out a whole lot.... nothing cools like water/alcohol injection...

[badceli]

True. Anything you can do to keep things cooler is probably worth the money.

that devils own controler is like the snow stage 2, you set the On and you set the Full, and its ramps up in between...

[moltenice]

the devils own kit is $250 shipped, how much does the snow one run?

[mukalicious]

i was looking at the snow one a while back. there were some people not from nc.org starting a GB and they posted it here. i forgot the GB price.
