Alcohol injection with Nitrous?
A thread over in C4 general made me think of something and I'm wondering if anyone has heard of it or has any comments about it.
In the Turbo Buick crowd it's very popular to run alcohol injection systems... gives them the ability to run upwards of 23 lbs of boost with pump gas and the systems are pretty cheap.
What would the effect of the alcohol be if you were spraying nitrous at the same time? The alcohol cools the cylinder temps down quite a bit...
Any thoughts?

Not too sure. I asked carroll way back about running water injection and N2O at the same time, I was told not a problem.
I was wondering if the N2O would freeze the water since the N2O is exiting at -127 degrees or whatever it is... Guess not

Alcohol and Nitrous do not cool down cylinder temp it cools the fuel and air that goes in to the engine.
Lot of people with roots superchargers use nitrous to cool down the F/A befor it goes into the engine, they use it becaus you can't get intercoolers for them, the more you can cool down the F/A before it goes in the more power you will get out of it.
That is why a plate system hits harder then a fogger system, because the plate system cools down all the air in the intake but the foggers are so close to the valve that it does not have time to cool it as much.
Indy car engines used a extra injector to spray in fuel in to the turbo to cool down the F/A befor it went in to the engine because they cant use a intercooler.
