water injection questions

[bbob203]

Would not be hard at all. The simplest way to do it would just be a case of "if RPM > X and throttle > Y then spray".

Another option would be one of the Auber gauges measuring EGT. You could use the alarm output to trigger the pump when EGTs exceeded a certain value. The same type of control could be incorporated in to an Arduino by adding a thermocouple input and then some more programming. At that point you'd also be able to do some other fun stuff too.

Nice! well ill leave all that up to the techies I'm not technologically proficient in the least bit. A standallone electronic vnt w/ water meth control and cruise control for my mtdi id be all up on it.

i have one auber egt gauge but unfortunally it only lasted 5 days...
i bought it and never installed it for 4 year or so and now that i needed it went kaput.
i am triyng to repare it here,if i can that would be a good way to trigger the pump.

so that pump can be made to work?what would be needed more to work?

Your going to have to point that out to me. Its not in the ad that I am seeing.

On the label of the pump.

air over instead of electric pump makes some sense to me, possibly  biased because I have more use for onboard air than water.

ok so I have to ask...

would it hurt the turbo to be on the inlet side of the turbo?

If not you could use a pressurized tank, hook up a boost side vacuum hose to the tank, then the outlet hose on the vacuum side of the turbo, then if you wanted to get carried away you could use a simple delivery valve that opened up at 10-15 psi or wherever you choose. this would mean that it would only deliver water when at higher boost levels. an adjustable needle on the delivery side or just different nozzle choices would control your flow.

some say that will erode the turbine.

Quite a few folks run pre-turbine. I was gong to run pre-turbo myself before I decided to let the WAIC keep it cooled off (that doesn't make it right though).

Possibly if it's a mist your ok but large drops could be an issue?
