Co2

[Noodle]

ive been reading about CO2 injection alot lately and was wondering if you shot CO2 directly into your carb would it help at all, or would it be bad for it, or would it do nothing at all

[Oldblueaccord]

Carbon dioxed? uh no. it aint flamable is the easiest way I can explain it,

so far ive experimented with di-hydro-fluroine ( basically the stuff in the compressed air cans u get at a comuter store or where ever) i was able at the end of the semester to do a few combutsion tests in my schools chem lab and found this stuff does burn quite well only problem it burns unstable, however it has properties like that of freon but im still testing it

co2 injection is for your turbo intercooler.

[bobafett]

yeah its a cheap easy way of intercooler cooling like he said, i have seen in a magazine it dynoed about 30whp on a pretty high (300-500whp ish) setup... so its definetly worth looking into, but probably only on a boosted car.

[Oldblueaccord]

Right but there using it to cool the outside of the intercooler. Compressed its very cold. You can use it to ship things frozen. I dont think its dry ice but its like it.

well dry ice is its solid form

[2drSE-i]

dry ice is CO2.

Dry ice burns the living crap out of you when you touch it. Basically what boba said is what I've heard and read. It's not super beneficial ona stock low-hp engine but, after you start making some good numbers it's like throwing icing on the cake. Remember they also have the intake pipe ones that you can hook up sequentially. Like one at the begining of your cai then another further down, then a third right before the tb. And all that's coming from the same push of the button. Pretty neat but pricey.

Don't spray directly inside, but route the C02 lines inside the intake... run a small tube or tubes thru the intake... but do not shoot the CO2 into the intake... the CO2 runs thru the tube(s) and comes out the other end. This will cause the small tubes to freeze and air passing past the tubes inside your intake pipe will be cooled.

Aim the sray of the CO2 nozzle so that it cools the intake manifold... that way it isn't wasted.

Just make sure the spray is far away from the intake filter.

Of course the more tubes you add the more cooling but also the more restriction. so maybe have a 2.5" diameter segment of intake pipe close to the TB where you can drill some holes and run the CO2 pipes thru.

wait wait wait so lemme get this straight a20. Instead of paying the like 150 that cyrotech wants for that special circle intake segment*if you don't know what I'm talking about I'll post a link* you can just get some copper *best heat conductor for the money* tubing and then braze a fitting that connects to a line that connects to the CO2 tank? What is preventing people from making homemade kits? The only issue that you couldn't "jimmie rig" would be the solenoid, right? And those you can buy seperate at summit. Could you use a Nitrous solenoid, sometimes you can find those for cheap on eBay. That would be pretty neat instead of paying the total $650+*kit plus intake tube*

[w00tw00t111]

The price to performance characteristic wouldn't be as effective as nitrous injection.

=/

Yeah but, at least where I live nitrous refilling is so outragesly priced you might as well open up your own filling station. Where as co2 is pretty cheap.

[ghettogeddy]

hears some products ive found for the use of co2 there made by cryo2 enjoy http://www.cryo2.com/products.asp?m=sc&cid=1

I know a guy that runs a Cry02 system. You can feel the difference, but you can easily go through a 5lb tank of CO2 in one night.

[ghettogeddy]

u can also go thu a bottle of nos in one night but this is safer and a hole lot cheaper im talk 200 less the nos with a ten lb bottle and all the stuuf to hook it op plus u can get the cryogenic fuel chamber and intake system for cheap

[w00tw00t111]

I know a guy that runs a Cry02 system. You can feel the difference, but you can easily go through a 5lb tank of CO2 in one night.

Ok but is it like just a slight increase or difference or does it sling you back in your seat almost giving you whiplash? Also, what type of Cry02 system is he running. There's different kinds. Also I've been thinking about this. What's keeping people from using like "industry" size tanks. I mean nothing *to my knowledge* is different about those tanks then the small 5lbs and 10lbs bottles. So like the kind that you can get from the dentist that size not the necessarily the size they use to fill up ballons w/ helium. Just a thought so that you don't run out as quick plus youre honestly probably paying a tick for the name brand bottle. I belive the NOS *brand* bottles from Summit are like 120 bucks which is insane! *You're paying for the name, or at least that my opinon* Just a thought

[2drSE-i]

nothing but weight keeps them from running industry sized tanks

[w00tw00t111]

nothing but weight keeps them from running industry sized tanks

Ok. Well that's the only thing I could figure but, even then an empty propane tank really isn't that heavy. I mean to get that much more life I doubt 15lbs would effect performance that much. Eh... but what do I know.

[AccordEpicenter]

from what i hear all the gains are negated because the C02 seems to find its way into the intake air and pretty much cancels any real gains. You can spray alcohol/water all over your intercooler to get a good power gain

[w00tw00t111]

I think mainly what was being talked about besides the intercooler sprayer is the fuel bar "chiller" and the Intake plumb tube thing. C02 shouldn't get in the intake tube from the intake specific tube thing unless the welds are just really really bad. I just wonder how good the gains are. I mean to me it doesn't seem like its worth it unless you're already pushing a lot of hp. Nitrous for the same price seems to have better effects w/o a doubt.

[89se-i]

i only road in the car once, but it felt like the difference from a sumemr day to a real cold winter day. personally i dont think its worth the money.

also 5lbs is the capacity of the tank, not the tank weigh. the tank is probably 10-20lbs depending on the construction material. the bigger type of tank i think you are talking about, is usually steal and can weigh over 100lbs. As for buying a generic tank, a 5lb co2 ank goes for about 60 or so.

I have been thinkign about making a diy system like cryO2. I dont know much about gas tanks, btu i think you need a dip tube, so the CO@ comes out as extremely cold liquid, instead of cool gas. Can anyone confirm this?

[89se-i]

accidental double post.

[ghettogeddy]

so i was thinking instead of using co2 what about compresed air

[A20A1]

Compressed air to?

[ghettogeddy]
