Which would be better to cool down intake charges and give a boost in hp? Can you run a small shot with Direct port nitrous? Or would a spearco water-injection 50%water/50% methenal be better?

 

You cannot run nitrous all the time, therefore it isnt a good method for cooling down the intake air temp. Water injection is far superior and safer for cooling down your intake air temps. I use and run the spearco kit and love it. I have no knock at all at 10psi on my stock block LS. I also am using an intercooler...so water injection is a little overkill, but you can never be too safe.

 

where did you put the fogger nozzel? As close to the throttle body as possible or more toward the intercooler?

 

Boostedhybrid how often do you add water? How are you controlling the h20 injecter?

 

I put the nozzle that sprays the water after the BOV and before the throttle body. I control the water injection right now by the pressurized regulator that comes in the spearco kit. As soon as I get the tuning software for my PMS system i will let the unit control the spraying of the water through a solenoid at my specified rpm points, but that will all have to wait till i get back to the dyno.

 

Oh i also use the 50/50 mixture of methahol and water. I refill the water resovior every tank of gas. I carry around a water 16oz water bottle to fill it...it is pre-mixed with the mixture so i dont have to worry about it when i am out.
