What do you guys think of this? http://cgi.ebay.com/ebaymotors/ws/eB...category=33742

If say you had some junkyard ic like a starion and rigged this up, you think it'd be healthy and benificial??

 

It would be a great idea in my option and i dont even own a TII but the basic idea sounds about right, colder the air is cooled going into the engine from the turbo(sence the turbo chargers air it naturaly makes it heat up) this should do quite a big of help and might add some life to your engine and 20hp sounds about right.

 

Ya I was thinking the same thing, coz CO2 dosn't seem like it would damage anything, and man that **** is cold, i had an experience with it paintballing, but I am just wandering why I haven't heard about it more?

 

i saw that last night, i was wondering if it would help on a radiator or oil cooler

 

i usually take ebay claimed hp increases and cut them in half, or 1/4th :P.


on a seperate note:
i've always wondered about using an efan on an IC. there are some high cfm efans out there...how come no one ever mounts one on their IC with a switch of some type to have it run full blast when activated. would a radiator e-fan not do anything for an intercooler? i mean the intercooler is always placed somwhere that the air can flow through it really freely, so i would assume the air cooling of it is a big deal. anyone?

 

bingo: a FMIC fan would be great for when you are stuck in traffic or behind people on the highway. But at a track I dont see a need for it.

As far as the sprayer, nitrous is colder. So even spraying that onto the IC would be pretty damn good gains. It would have better gains spraying a 35 shot into the intake though

 

this would help..as far as the price I don't think it will work!!

 

I could make it cheaper then $100. Ill make one for my stock top mount IC.. ha home depo that thing. Hit it before racin. It would be for %50/%50 (form/function).

And i agree No2 is colder, and would make better gains IN the intake. Gimmie $500 and ill blow it up with a 200 shot. It would be really crazy fast... for one run!

So yea make one for half the price.

if you search for scathart in the 2nd gen section you'll find loads of info for running n2o on the t2. I recall he was running something absolutely insane 175+

 

yea but how long does it last before it blows.??

 

I dont believe he ever blew his motor using n2o?

 

hmmm so is n2o safer on an rotory than normal piston engines?

ill spray the hell out of it.

 

I don't think that thing would have the capacity to make a huge difference, but who knows.. never know until you try.

 

I think it'd be a good idea if you wanted to get a little edge in a drag. Couldn't possibly hurt.

 

let me ask you guys something. C02 = carbon dioxide right? I never was good at chemistry and atoms, but that's the same stuff that we exhale right? The way I look at it is, it's carbon dioxide, which means it has less oxygen in it than the normal "air" that we breathe. And even though there is 1 carbon atom and 2 oxygen atoms, maybe that would hinder power or something? I mean, I may be completely full of ****, but there has to be some good reason why CO2 isn't used in cooling applications. I sure have confused myself....

EDIT: WAIT! Maybe they don't use it because there's nothing to oppose the power it produces. Like N2O actually has the nitrious oxide preventing detonation. And since carbon dioxide wouldn't really have anything to help prevent detonation to go with the power production, it wouldn't be a safe application? Now I'm really getting far fetched... I better stop.

 

sounds like it'll work to me.....colder intake means denser air, more air + fuel = more power, also cooler air has less chance to detenate..

 

cooler air means less chance of detonation? That's news to me. I thought it was just more air than fuel and a bigger "bang" and just too much of an explosion was what we call "detonation". Being that it's too powerful an explosion. Please correct me if I'm wrong.

they're not talking about CO2 in the actual intake, just spraying it on the intercooler to cool IT. Like when u turn a bottle of that "air duster" stuff u use for computer keyboards upside down and spray it on something. it actually frosts up. cooling the metal the intercooler is made of would cause the air that passes through it to cool through heat transfer. good idea actually...

 

see! I knew there was SOME flaw in my thinking. But that still doesn't explain why it's not used more often.

 

then why do people get front mount intercoolers???? Kanaida ifthat was the case themn NO one would upgrade there IC and just upgrade there fuel system....which has resulted to me a blown moter twice...

 

the air that passes through the front mount never actually gets into the intake charge, it is meant to do the same thing as the intercooler spray, just to a lesser degree. The reason it isn't done more often is that it isn't very practical. It makes sense on a drag car(haven't u ever seen someone at the track with a bag of ice on their top mount?) but wouldn't do any long term good on the street. you couldn't continuously use the co2 as you were driving. As I see it, it's just one of those things you might do at the track just for that tiny edge over the next guy... plus it'd sound cool to say "yeah, I have a co2 intercooler spray kit..." lol

 

Detonation is the mixture igniting before the spark plug fires, and one of the main causes is the fuel/air mix being too hot. The cooler the air entering the engine, the higher the threshold before detonation occurs. Cooler air is also denser, meaning there's more oxygen available to be combined with fuel and burnt. This is why cooler intake air gives you more power. This bigger bang from this is not detonation, and doesn't cause it.

 

That CO2 spray looks like it would work very well, but the guy doesn't mention anything about how it's controlled, i.e. what triggers it and when. Most people think that you should turn on the water/CO2/N2O spray whenever boost or intake temp reach a certain point, and then switch it off when they drop, but that's wrong.

Read this article from Autospeed. It explains how intercoolers actually work.

 

On a related note, someone in the 3rd gen forum rigged his rear windshield washer resoivoir to spray onto his Intercooler. He said he puts ice water in it and notices a significant drop in intake temperature when he sprays the IC. Sounds like a decent idea...

Anyone have any comments or experiences with anything of the sort?

 

well im gonna make one for my stock top mount and ill post some pics... iv decided to try to make one for cheap as possible to prove it can be done for dirt... then maybe ill make another thats all nifty lookin.
