intercooler sprayer

or super afc II


i've been meaning to get a afc but money was an issue. now its diff

what do you guys think i should do

as far as the intercooler sprayer, i did some investigating

cry02 has the sprayers just barely small enough to fit our small little intercoolers. its 8x4 inches and are $70 a piece

the bottle was gonna be a problem till a guy i know with a celica gts blew his engine and is gonna sell me his 5 pound bottle for $150 wich is $100 dollars cheaper than normal, with all the parts to go with.

if i get the sprayer should i get it so it kicks in at full throttle or just push a button?

just wanna see what you guys thoughts on it are.

safc, co2 sprayers are bad, n2o sprayers are better, but the majority of the power gained is from n2o being in the ambient air after the spray and your intake sucking it in.

If you want to cool your intake charge just buy some DSM IC and have them modded for our cars.

[youngvr4]

the majority of the power gained is from the n20 freezing the intercooler so when the air hits it its very cold air meaning more power right?

and why is c02 bad for freezing the ic?

[talskinyguy]

No, very little hp is gained from the cooling effect. You are better off just getting a more efficient IC.

Ambient n2o is in the air and is like spraying a small shot of n2o when it gets sucked in your intake.

Spraying co2 displaces o2 in the engine and you can actually end up losing power if spraying at WOT.

You could spray either right before a run and it would help, but spending that same money on upgrading your IC's would show a much bigger gain, as you could use it durring your WOT runs.

ok, i'm tryna completly understand you here

if i hit the gas 3 o clock pm 95 degree's outside, i feel a strong loss of power
if i punch it 3oclock in the morning at 50 degree's outside the difference is huge!

so your saying that though the air will be much much colder therefore adding hp, that because of its elements it would go into the engine and kill the hp?


what i will do is buy his bottle for the cheap price and just fill it up with nitrous, instead of C02

[talskinyguy]

you could do that, but I still think you would be happier with dsm sidemounts.

well, if you do decide to go with the CO2 sprayer kit, i will sell you my old kit that someone on ebay didnt pay for so i still have it. It includes everything to run it, both sprayer bars, lines, 5lb bottle thats probably 80-90% full of CO2 with mounting brackets, wiring, solenoids, and a flip switch to run it electronically. I dont need it anymore since i went to a front mount. It was very neat, i will say. Only problem is one of the fittings i had used (paintball fitting my friend gave me) i cannot figure out how to open it up to pull the old cut line out, but maybe you can figure it out, if not, you can buy a fitting for it at home depot for a couple of bucks. I can let this go for 200 shipped if your interested.

so talskiny, i believe you're explaining that since CO2 doesn't combust, it could therefore cause a loss of power if it enters the engine, causing less of a combustion than normal.

as far as N2O spray goes, ya you would benefit from the side effect of N2O in the air, as well as its cooling abilities.

so if you go with CO2, it can cool, but won't combust...so that could rob you of hp gained by the cooling

but if you go with N2O, then it cools AND combusts, so you would increase the hp furthermore with its combustion on top of the cooling effect.

Talskiny is correct about the N20 sprayers. The cooling effect isnt where the power comes from, its the n2o that gets into the engine. A few dyno tests I have read all came to the same conclusion on that.

That is true - reason being - because the air is denser an the fuel is colder- an the colder fuel an dense air mixture the better throttle response you will get - being why when u shoot a shot of nitrous ox into your engine it gets a wake up of powering because nitrous is an extremely dense an flam. gas it will give you the best pony lift in such a short period of time.

I bought an installed a fuel cooler that mounts just like a FMIC which i would also buy, an u can mount the fuel cooler right infront of the IC being that is small it wont block any of the flow to the IC an still allows both to function great. I noticed a strong difference in the fuel cooler, most fuel coolers will cool the fuel 80 degres which is superb, being that u tank picks up alot of heat just from the exhaust.. which u damn well know u cant just go out an touch ur tailpipes when its been running for over 10 mins.. so u know it really hot ..
you can pick em up for $50 + in outa summit racing
its a cheap an well worth the 50$

i understand what you guys mean by the nitrous bieng the good and co2 the bad, but its basically impossible to say that freezing the air going into your ic will not increase your hp. also this affect will not make much diff on a dyno in the first place because the car is not moving and there is no air bieng forced into the ic. so of course it wouldnt show much on a dyno.

and any turbo charged owner on af can tell you the diff between hot air cruising and cool air.

i would understand if your saying that you can get maybe more power from the nitrous getting in the engine than that of cold air, but to say freezing the air going into your ic doesnt give you power is out of the question.

understood, n20 it is.

[talskinyguy]

Actually you will see a higher effect on the dyno because of cooling effect. IC's work by having moving air. So if you dyno it without freezing the IC and no moving air your IC's will heatsoak like crazy. Then you spray and freeze your IC's and the temp difference will be much greater than you would actually see on the street.

I still say DSM sidemounts, even its for the flow alone.

[youngvr4]

how about both?

[talskinyguy]

even better, but you sounded like your budget was limited.
