I came across one online and was curious if anyone has any experience using one on the track and if they are worth it or not. I personally dont know why you would use nitrous when CO2 is cheaper and just as cold and not flammable but to each his own i guess.

Nitrous is non-flamable.

I would do a search and you'd find the information you're looking for.

my mistake in my wording, because of the increased amount of oxygen it it is a combustion accelerant as opposed to CO2 which is a combustion inhibitor.

Mark Strand aka 68COUGAR was working a design for CO2 intercooler sprayer a few years back when he still lived in the states. He has since sold his XR7 to Dalke though iirc, and is in the Philippines last I knew. Too bad, he was my bizarre and boozed mentor for awhile there. :) I can't say if he ever had fitted it onto his car, but he had a working prototype I believe.

Several people have tried the Co2/Nitrous intercooler sprayers and they didn't do enough to justify the hassel. Mainly because they are only good for a few seconds of extra power. Picture sitting in the staging lanes just prior to entering the burnout box and hitting the button on the sprayer...lots of hissing and what looks like a cloud of steam rolls out from under the hood while you hold the sprayer on for 15 or 20 seconds to cool off the intercooler (which is now half clogged with frost). You do your burnout and even before you can get the car staged the intercooler has heated back up again.

You could try spraying while going down the track, but once the air coming through the front of the car increases, the spray pattern gets smaller and is less effective. Unless your charge air temps are high enough to cause the computer to pull timing your not going to gain much power. An IC fan would be a better way to keep the air temps down and it's something that will be working all the time...instead of only working when you spray.

PS: If your going to spray nitrous, spray it into the motor.

what if you sprayed directly into the i.c. wouldnt that do its job and possibley get a little into the motor?

I assume your talking about nitrous....and if so, the best place to spray it, is after the intercooler just prior to going into the intake manifold (on top of return plenum).

I was never planning on using it myself, it was just more of a curiosity question if anyone has used it and the results. I know from what I read of a setup being used on a 600hp civic (i know i hate them too but that is what they used). it gained 68hp.

there is no reason to hate a honda hate the people who try to "hook them up" i have a honda civic and had acura integra.they both made 120hp/per liter which is sweet but the reason for import tunning is parts readily available and cheap just like the old hot rodder seen in the fifties and sixties.

but what i was saying if you spray the nos into the i.c it would freeze i.c. housing and then go with the air into engine isnt that better than wasting the spray at speed or warming before the run

This is where David is saying to mount the nitrous nozzle to spray into the motor, after the ACT sensor and before it goes into the lower intake. This is pics of my black '94 motor.

I lived in Orlando for 5 years. Everyone (and I mean everyone) there who has a civic, integra, accord, etc. thinks they are "fast and furious" by adding some rims, a spoiler (useless on front wheel drive), lowering it (but not aligning so tires are toast within 5k), and adding a 4 inch muffler. Every one of them blasting reggaeton which every song has the exact same beat. Those movies brought too many idiots into the car scene. Perfect example F&F Tokyo Drift. The mustang in the last scene supposedly had a turbo straight six in it. Well When they actually built that car for the movie it wasnt able to pull off the drifting scenes. They had to build a second mustang with a 430 windsor. (trust me I did the research)

With that all being said. If you have an import and understand what cars are really about and what they are capable of then I have no beef with you. Im sure there are plenty of guys out there who have great cars, I have even seen a few i liked (none are hondas but thats just me). I have a great respect for a supra, 300zx, rx7, evo, sti, and the list goes on. Like most of the guys with supercoupes, part of the reason I love SCs are the exclusiveness of them. Civics are a dime a dozen.

Sorry for the rant I just get going sometimes. lol

Now to get back on topic. What if you blocked off the intercooler from air flow and sprayed CO2 onto it the entire pass. It would most likely freeze the cooler and that wouldnt be an issue for airflow since it being frozen would be more effective than the airflow itself. Just a thought.

Why don't you just install a water to air i/c then?

You like the rotaries or just RX7's in general? I have a '90 GTU with a 347 (started as a 5.0HO) stroker and a 250 shot :) built C4 MSD, etc... It has a body kit so most people say "ricer" but I am usualy too far ahead of them to hear it...

both, have to love the wenkel just for the smoothness of it. but i do like the rx7 and rx8 body style

Dave,
I was also looking into this stuff and was trying to get things a bit more consistent, not so much looking for more power, (that would be a nice added benefit tho!) perhaps to eliminate all the stupid Ice I take to a day of racing is really what i was thinking about.

You know as well as anyone when things get heat soaked, ACT keep going up, and there is not much to stop it. Even with meth injection things get very hot and all during a day of racing my times get slower and slower, unless I have a while to cool off and lots of ice on all the intercooler tubing.


And yes I was certainly talking about spraying all the way down the track, and was hoping with the intercoler fan I have and the added forced air from the speed it would force the sprayed CO2 further into the intercooler before frosting occurs. How long would it take to frost I guess would depend on how hot the intercooler is would it not??

Do you see any added benefit for consistency rather than added power?

I too was looking to hear from anyone who had tried it with any results you may have seen.

Just some thoughts!

well i even have to ice the the hell out of mine.
To get my fastest time's even with my snow kit.
So if the co2 can keep it that cold down the track then i would say yes it should work.

Smitty,

The CO2 systems I've seen have problems in 2 areas. Clogging of the holes on the spray bar and emptying the bottle very quickly, because of the number of holes in the spray bar. The clogging has to do with the change from a liquid to a gas state which is also what provides the cooling effect and why it's important to locate the solenoid as close to the spray bar as possible.

When you consider that stuff and the difficulty of getting the bottle refilled or using rented bottles from a welding supply shop, I just don't think it's worth the hassel. Pretty sure the people at the track are going to think your car is on fire too, and that may cause you some unwanted attention from track officials.

When they see that you have a C02 bottle in the trunk, some tracks may treat it the same as if you have a nitrous bottle and require some type of pressure relief valve with a blow off vent outside of the car, or they may just ignore it and treat it the same as CO2 used on turbo wastegates or transmission shifters.

David

PS: I think you would be much better off with a methanol injection system.

well you can get the co2 very easyly by going to a paintball store.
I play alot co2 fill for a 20oz bottle is 4.50 i don't know how big the bottle's are on the kit. but you can get it anyware pb stuff is sold.:D

understood but say you where using a fogger wouldnt that be better than nothing? i know what your saying about nos into the motor but as i side effect wouldnt that be better?

When I used snow (dry ice) on all om my intake plenium, top tube, bottom tube, intercooler packed and surrounded by 1.5 inches all sides, and blower top. All this sat for 1 hour till everything was nice frost covered. Then started the car up and waited 20 min in a long line to the staging lanes. Did a burnout and launched it down the track with co2 tumbling out as I drove. After getting back to the adjacent 3/8 track infield and opened the hood. To my surprise the setup was still frosted and even refrosted my fingermarks!

2 of my friends and I are plotting to build up a 13b a little bit and mount an M90 to it (large pulley probably) and see what that does for the torque. If it works out good we're going to put an MPx on. We need to find a better FC to put it in though, the one we have is kinda meh. I think it'd be a rad drift car. :eek:

What of you put the CO2 on a switch so it only activates at WOT? Then there shouldnt be any worry of it freezing up on you and will still run the whole 1/4. No need to worry about it running out from using it while staging or anything. I dont know just my thoughts.
