hi i am not sure if someone has asked or talked about this , but who has sprayed nos in there intercooler and how much did it help, or not help?

 

havn't sprayed n.o.s. yet on it but plan to set up a kit to do it. all it can do is help. n2o has serious cooling effects on the intercooler. n2o has a melting point of 91 degrees below zero celcius which will have good benifits on heat soak, and get a denser air charge. might not be huge but cheap to do and worth it in my opinion.

 

What about simply spraying water? I'm planning on installing a water kit with my TT install. If need be, I can add some ice in the reservoir for extra cooling effect.

 

Intercooler sprayers can be effective, and they have a high coolness factor.

A lot of people are getting interested in water injection, as a better way to keep intake temps down, and help with knock suppression. I am looking into both options now.

 

If you look in this months Sport Compact Car. There is a G35 with a vortech done at Zcargarage. They made 505whp using the Nos intercooler spray. Without the spray it made 438whp.

 

Its a dry shot, try it with CO2 and see what kind of gains you get. If you want to introduce N2O into the system do it with a proper setup.

 

NO2 likely got introduced into the intake track. It's pretty common. Intake temps probably dropped 10-15 degrees, and that is nowhere near enough to gain 67whp. The rest of the gains came from the dry-shot effect, as Lorca pointed out.

 

My friend have the NX Intercooler kit with the Greddy TT and the car jump from 401 rwhp to 450 rwhp... very impressive for just a spray in the Intercooler

 

Im not to familiar with how it works but does it matter if it did get in the intake tract. If it made 70whp does it matter if it was in there or not. Im guessing maybe from a reliability stand point, it sounds like a dry shot is not good?

 

Exactly...the NOS is being sucked into the intake like a dry shot. This would spell disaster on a TT car. my new project is a intercooler/radiator sprayer. I'm going to use a system that SCC used on one of their project cars using a Stainless pipe to feed 4-6 garden misters. I will be running it off of the washer bottle with a two valve so I can switch between using it for the windshield washer and using it for the sprayer. I figure I'll just run straight water in it as I dont use it much anyways...

 

That's correct...a dry shot of NOS is very dangerous on a high pressure F/I motor. It causes the A/F to lean out, which can spell disaster if it gets too lean.

Ideally, a NOS setup should be wet, or at a bare minimum, some kind of pressure pressure increase needs to occure as the NOS is introduced. But either way, you need to add more fuel.

With the sprayer, some NOS always gets sucked up by the intake, resulting in a leaner mixture, and a power spike.

 

Anybody on here use the N-tercooler with CO2 instead of N2O? I would think that would show some gains although not as much as the N2O getting sucked in by the ic...

 

I heard if C02 get sucked into the intake . It would bog the motor down . I was looking into that . But if I do any thing , its going to be water injection , and or spraying the IC. That seem like the simplest and most cost effective way.

 

I've been wanting to do this too. How much would that setup cost? Groupbuy>>>>>

 

if you do the home made garden spray, you could prolly get all the parts you need from home depot for less than 20 dollars.

 

I got an idea but am very lazy! Why doesn't someone make a complete kit that sprays the IC and radiator from the parts from Lowes and sell them. I bet you can make some money if it is quality work. Just my 2cents. Isn't someone on this forum completing a water injection kit for the Z?

 

I plan on doing just that. Except I am not going to use regualr PVC from Lowes. I am going to use a Stainless Steel pipe for the feed polished of course and some nice silicon feed hoses as well. I am going to try to get all the parts together this weekend and start doing this.

 

I havent done any test, but the intake temps drops from spraying water onto the intercooler are likely very modest.

Lorca and a few others have done water injection on the 350Z. After reading up on the subject, I am convinced this is a great way to go...particularly on extreme duty applications, high whp, and lower octane fuel.

I would still maintain that with a perfect tune, water injection isnt needed for most applications. But getting a perfect tune that is perfect in all conditions is a challenge in itself. WI seems like cheap insurance again knock, even if you use it simply for knock supression, rather than to increase power via more boost, leaner mixtures, or more timing.

WI adds a layer of complexity to the tuning process, and I would hate to rely on it for a safe tune. So my advise would be to tune safely, then add WI as your insurance policy against detonation. That way, if the WI fails for any reason, your motor is still safe.
