Is it possible? Do I even want to know? Has anyone tried it? how about straight Co2?

 

I hope you're not referring to using CO2 as the enrichment part of a nitrous setup. Since CO2 is an inert gas, you would quickly turn your pistons in a nice lump of scrap aluminum (extreme lean condition).

 

You cannot substitute CO2 for N2O when using it as a power adder as in spraying into the TB.

Now many S/C and Turbo guys use nitrous soleniods and such to spray in front of their intercoolers to cool them down. They substitute N2O for CO2 b/c Co2 is cheaper and cools the air more than regular airflow going across the intercooler. Again, they do NOT use it as a power adder by injecting it into the motot, buy by cooling the intercooler to make more power.

 

If your talking about "pushing it" Then yes but not with CO2 just nitrogen.
