All,
Am installing the basic system in my R53 supercharged MCS. Am aware of the posted install "how to" for the MCS. The maximum tuned crank power of my water injected and tuned engine will be about 225 whp. Am wondering what nozzle placement will deliver an even injection fluid distribution along the entire stock MINI intake manifold?
The stock intake manifold is a log affair with the compressed air entering from one end of the log. Each of the four intake ports branch off the intake log manifold at a 90 degree angle. The end of the log intake manifold, away from the inlet, is a dead end. This is fine for the air: the fuel is injected directly at each intake port. But, I am concerned that if I inject water/meth at the inlet end of the log manifold, the injection mixture will tend to concentrate at the first couple of intake ports and not result in an even fluid distribution at the far end of the log intake manifold.
I am thinking that I can place two 0.4 nozzels along the log manifold, one at the air entrance and another toward the far end. Is this reasonable?
With two 0.4 nozzles am I going to inject too much water/meth fluid for this 225 whp engine?
While I am at it, I have another question about installing a priming pump at my water reservoir. My water reservoir is in the trunk. I can easily install a high capacity water pump to prime the water injection pump. My water pump is capable of 60 psi. Is 60 psi too much priming pressure for the Aquamist injection pump? Or, will that be okay?
All help will be appreciated. Thank you in advance.
