Where can i get a water pump for a water injection system. Really all i am looking for is a pump that is activated by a vacummn line in a car. Anyone know?

 

Why don't you have a water pressurizing system and have a valve activated by vacuum rather than the pump itself? If you think about it, this is how fuel injectors work.

Water injection during combustion can be really dangerous for the Max's high compression ratio. If you mess up and inject too much water, just remember that H20 is not compressable and might send your cylinder heads through your hood, blow holes in your pistons, or bend your connecting rods. Keep in mind, this metal deforming isn't due to an immense increase of power but rather detonation because you are effectively increasing the compression ratio.

H2O injection is still under a lot of R&D.

 

Thanks for the clarification. Just an idea for a future project.
