c02 ic sprayer,good or bad thing?
I have searched this topic without much luck.My future fd mods are, 62- 1 single,lg v-mount ic, c02 sprayer,pfc, wideband,knock,sensor jacobs, larger injectors,etc.all the go fast goodies.the motor is just rebuilt with a streetport.and will be tuned by steve kan in a couple of weeks.Is anyone running this setup on a street car now?any imput on this would be helpful.

I understand that c02 can get sucked into the intake,but this system has seemed to work on piston engines.no one else on this forum is using this?damn,my first single turbo fd will have it,and the current owner is scheduled to have steve kan tune the car with it.I hope this is a good idea,because i would hate to pop a engine using a new or unproven idea.

Did Steve Kan say he would not tune if with an IC sprayer? I'm putting on a full CRYO2 system (fuel, air and IC) and would be very interested in the position of a reputable tuner such as Kan.

Some of us Columbus guys (Nocab72, Asleep, and myself) tested both CO2 and NOS IC sprayers a couple of years ago. The inherent problem is the gas getting sucked into the intake. Unless you plumb your intake into the brake duct area in the very front of the car, it is nearly impossible to NOT ingest the gas. CO2 will simply cause the engine to stall, starving the combustion process of O2.

umm how is the gas getting into the intake track by spraying it onto the intercooler? The intercooler is a sealed unit obviously to prevent pressure drop during boost. The intercooler itself is not pourous to allow the c02 to enter it.

he ment that the spray will go trought the fins on the intercooler not in the intercooler its self .. most single turbos suck so much god damm air that any co2 that goes trought the intercooler will definatly get sucked into the intake .. im not sure but i think ( so if im wrong let me know ) co2 displaces oxygen so you might run lean or rich or whatever one of the 2 ....
Alcohol and water inj is a much much better choice in my opinion

I am buying a car with the c02 kit on it.I dont have the car yet,and steve will be tuning it in a couple weeks.robrx7 is still breaking in the new motor.what if you just spray the ic BEFORE you do a full boost run,wont it cool the charge like a cold day ,when fds run like a bat out of hell?

well first of all the intercooler is not on the suction side of the turbo, it's on the pressure side, so it can't "suck" any kind of gas into it. yes it does blow the co2 onto the fins, but what it's doing is cooling the intercooler. Again as I said before the intercooler is a Sealed unit,fins and all. so nothing can get sucked into it and nothing can come out of it, it's air tight. If they could suck air in, then you would see all kinds of people having problems creating boost and maintain the boost because it would leak out of the intercooler.....some of you guys need to read up on things and see how they work before jumping to conclusions without all of the facts. Don't trust everything you read here!!!

i run the nx kit and spray nitrous with it in case it does go to the intake id rather the nitrous get in then the c02
Ps it does make a difference the butt dyno probably wont notice but on the datalogit it drops intake temps like a champ

TrboRty i think what every one is telling you is that on single turbo cars the air filter on the turbo will suck in c02 when it blows threw the fins of the intercooler because the air filter is right behind the intercooler

Yes, spraying the fins of the intercooler (the outside) will result in the C02, or whatever gas you use, being pushed into the engine bay and ingested through the intake. Unless the intake is positioned so as to not ingest the gas, this will not work.
The hazards of using a combustable gas (Nitrous) would be catastrophic if it is injested in amounts enough to cause detonation.
As I stated in my earlier post, CO2 will cause the engine to stall due to the lack of O2. Without adequate O2, combustion cannot occur.
We used a ring mounted in front of the FMIC and put the car on a dyno. A baseline run was made without spraying. Then Nitrous was sprayed for 5 seconds. A 20 Hp increase was noted. Then CO2 was sprayed and instantly stalled the engine. 4 different times. The intake was ingesting the gas.
No FICTION, just FACT!

Reading/Comprehension>TrboRty
LOL, I think you need to read what everyone else is talking about...they arent saying that spraying CO2 on the IC will suck it in there, they are saying after it has passed through the fins on the IC the gas will get sucked into the turbo charger as most single turbos suck in air from the engine bay..you know...the air has to enter the the engine somehow right...and its starting point is the compressor on the turbo..... and I think they are refering to us guys running a large Race Stock mount IC.

Do you guys think that only pure c02 will reach the turbo ? I havent made my mind up on a co2 sprayer but this seems impossible.
My FMIC is sealed off very good, so much that with the fans on there is enough suction you can feel it on the outside of the FMIC. Damm thing will suck paper right off the ground. So with all the air its moving in I cant see a spray of Co2 making my engine cut off. Yes I would imagine the co2 content in the air will rise , but not to the point it starves the motor and makes it stall.
I wonder if the stalled FD mentioned above was with sitting stationary and no real air flow was going on.

The following is from DEI the mfr of the CO2 sprayers:
"There is indeed a possibility that co2 can find its way into an intake but we've only noticed that in a few applications, primarily the LS1 5.7L motors and some custom twin turbo apps on Nissans as the air intake is located directly behind or very close ti the intercooler where there is a chance of co2 actually being drawn into the intake.
For the most part, tuners and builders have redirected the intakes (sidewall mounted with shield) so it constantly receives a direct feed when in motion. I'd say so long as the car is in motion the likeliness of co2 being drawn in into a filter element/intake is slim as when in motion a considerable amount of front drag pulls any co2 (as it is heavier than o2) down under the car with the air stream."

well oviously you didnt pay much attention to what i wrote ...
but i guess it would be hard but not impossible to suck up c02 if you had a front mount (what i currently have )and then it some how had to also go trought the radiator and the fans and then into the turbo ... i have a t88 on my fd and at iddle that monster can almost suck in your hand ... i can just imagine how huge the sucktion would be say at redline and 20+ psi...so you must understand what i meant by that ...
now on the other hand if you have a large race stock location intercooler then the chances increas dramatically of sucking in whatever is sprayed tough the IC!! with no radiator for the gas to also have to go by ..so yeah im sure if you dont have it shielded for the turbo then you will most definatly suck up what ever gas you plan on using ...but then again i think an IC spayer would have a better affect on a stock location IC than a front mount...
i know that a cooler intake charge will make more power .. duhhh ... but wh not just go ahead and use meth inj ??? not only will it give you the extra hp you looking for and the cooling that you need but it might actually save your motor if you ever ran a bit lean ... just my 2 cents !!!!
