Scince every one was talking about the tornado yesterday, I was wondering if anyone ever tried or looked into this...

that looks like a garbage product... how can adding CO2 to your intake make your car run better.. Co2 is a non cumbustable gas.. in my opionin if you add more CO2 youe taking away from the amount of oxyfen needed for combustion... the only thing i can see this used for is to cool an intercooler and pretend you got Nitros with that purge valve... IMO it looks like a waste of money...

 

yea, Co2 in the intake would mess with the mixture and i would think that if anything it would make your car run like crap

 

From what I can see on the website, the CO2 is not fed into the airstream. There is a little aerodynamicaly shaped bulb in the intake tract the the CO2 is feed into and works as a heat exchanger. Same thing for the fuel line. If you know the area of that bulb you can figure out what kind of tempurature drop you can get but my guess is it would be negligable.

Looks like the insert would create a volumetric restriction more than anything else.

I've seen fuel coolers run on drag cars though. Basically wrapping some kind of coolant line around your fuel line. I'm not sure it would work effectively though.

Liquid Nitrogen on the other hand... Now that might make a difference!

Of course, it may make your fuel line brittle and crack too, but it would definitely cool down the fuel which would cool down the air charge when it atomizes. Again, without empiracle testing, it would be hard to tell the kind of improvment you would get out of it. At least if you used a closed system you wouldn't have to replace it very often...

I wonder if you can pick up a gallon at the local Home Depot for testing?

They sell something simular to that.. But the intake does make sense, colder denser air provides better combustion which =more horsepower..But it is definetly not worth the money... Just wondering if anyone has tried it.

 

i have seen it on a corvet,here in reno. and befor he hade it i wached him run a chevel that was blowen and noset and he could not take him.then he got the dei co2 system he took him by 1/4 of a car so it dose work. is it cost efective probly not but when dose that matter.

 

I read it and it works by cooling the air charge going into the intake not by adding CO2 into the air charge. Could be used on a turbo with an inter cooler to lower the air temp entering the engine.....

 

There are so many factors involved when racing that you can't validate if the system works or not based on one run. You need empirical data i.e. dyno numbers.

 

I guess scince no one has tried it I will test it out should be good. Ill just use my g-tech to measuer the difference.

 

If you're going to use a G-Tech, you should do several runs without it first, then several runs with it, then several runs without it again.

The G-Tech is a great little add-on, but it's not as accurate or reliable as a real dyno.

I would follow this procedure even with a dyno, but with fewer runs per configuration.

 

Yeah I want to dyno to see what my hp really is, but I ran with at the track, for 1/4 mile times it was no more than 200th of a second.
