Thread: Using water injection with N/a engine.

Has anyone ever used water injection with a n/a engine before? I know it has a similar effect as nitrous but hey water is alot cheaper. LMk your thoughts.

yeah there is a big difference between water inj. and nitrous... not similar at all.

I have thought of doing a water/meth setup with a high cr ve motor. This would keep me from having to use race fuel and eating o2 sensors.

Water Inj on a NA motor will make the car run slower.

Alright that answers it all right there.... What a let down

Here is one major reason it does not work.

If the outside temp is 90 degrees, the water injection temp will be about 90 degrees. So there is no benefit from cooling. ( you actually will lose HP )

See on a turbo car when you have inlet temps go up the intercooler cools of the air that is beeing compreesed,( as we know the more you compress air the hotter it gets ) but the intercooler can only do so much and spraying water into the mix can help even more.

The problem with an NA car is when you spray water in you are taking up a large amount of space for water that could be taken up with air to make more HP. So even if you did spray cooler water in, the change in air temp would be offset by the percentage of water to air ratio going down less air less HP.

What about water/meth instead of just water?

I believe a 50/50 water/meth mix together with pump gas will net aproximately 116 RON.

I can see that working on a high cr motor.

Your gain in octane will only be for a loss in air going in to the motor that will offset eachother for no real gain in hp.

Has this been proven or tried and tested by someone?

O man your in for it now!
