Water Injection can be a great tool. I know many different car's than use SC/Turbo's that run them.

Does anyone here use nitrous and WI?

Has anyone thought about it?

 

I should have made it clearer. I am asking about Direct Port Nitrous setups.

It may be a dumb question, just one I thought about at work.

 

Water or alcohol injection is not needed with nitrous, just like an intercooler is not needed with nitrous.

The purpose of WI is to cool the intake charge. Water injected into the hot intake stream is instanly vaporized into steam. Of course, energy is needed to vaporize the water. This energy comes from the hot air. After the air has given up the energy to vaporize the water, it is cooler.

This is already happening with nitrous injection. When liquid nitrous oxide is injected into the intake, it vaoprizes instantly...cooling the intake charge.

 

Meth and n2o? discuss.

 

Crystal meth?

Or methanol?

 

I knew the Nitrous cooled the combustion chamber. I was just curious about the 50%water and 50% alcohol mix injected with nitrous.

The anti-detanation help from the WI is what I had my little brain on.

 

The steam from the vaporized water does provide a buffer in the combustion chamber. But, so does the leftover nitrogen that dissociates out of the N2O.

Same effect again...

Plus, normal temp intake air on an otherwise NA engine might not be hot enough to vaporize the water/alcohol as it is sprayed into the intake.

 

The latter never even crossed my mind
