EDIT: I've done some major research, and I've definitely decided to only run CO2 in the intercooler spray bar and NOT Nitrous!
Also, I'm running an upgraded TMIC and NOT a FMIC, so I think with a good TMIC intake shroud that I won't have CO2 gases drifting into the OEM intake.
Again, I'm hoping that the intercooler spray setup will eliminate heatsoak when the car is stopped (like when waiting in traffic at a stoplight) Later on when I add alky injection that will help for tuning.
So again, if I did the setup mentioned above, would it be safe to "freeze" the TMIC with C02 and still spray alky into the throttlebody?
