water injectors placement 1.6 liter engine turbo

[lennoxlewis]

Hi guys, new to WI world, still getting knowledge in order to do a good WI system. I have ERL's MF2 and i am searching for the parts requiered to WI besides de MF2.

But the question is, where to put the injectors, how many should i use?

Turbo is running 0.8 bars and CR is at 9.5:1

thanks

Post some pictures of the engine!
And search the forums, maybe you will find your answer.

This is the engine without turbo



this is a better view of the inlet manifold but without the throtle body




if you need more i will provide

thank you

A classic location is just before the throttle, ideally facing the throttle plate.
This way you get decent distribution amongst the cylinders.

Ideally you'd want port injection, but this is only a 1.6 running low boost (relatively) so the nozzles would have to be too small to be practical.

Let's see what the others here think :smile:

thanks johnA!

dont the spray before throtle body manage to have effect ?? because with mid/high temperatures the mist would evaporate instantly no ???

and the water would create rust on the TB after some use no ??

thank you

no. :smile:
The methanol evaporates fast, but not the water

no :smile:

the water mist is only injected when the air is moving very fast. It doesn't just sit there stagnant.

I would say if you there for cooling then go pre-throttele body injection.
If you trying to supress detonation then port injection.

You have nasty 90 degree bend (trottle body VS intakes) that will make water to be delivered unevenly. So for detonation supression it will be not a best option.

what about if i use my Mf2 for fuel injection, where can i find infos on that? this forum is all about water right ??
