It is liquid....Co2 in a closed container under pressure is liquid.

The subaru guys had a problem running lean. I guess it all depends on how much gas your injectors can squirt out. They have to max out there duty cycle at some point. Especially with a procede ontop of that. But I have no idea if you can max out direct injection or not. But running lean is and should be one of your number one concerns no matter what type of ecu or piggy back you have. Lean is no laughing matter.

There's so much BS information in this thread I swear I lost 10 points off my IQ just by reading it.

Wait, I'm confused (no surprise there)..
Are you guys talking about a intake stream injection system, where the CO2 is injected into the intake, and therefore makes its way into the combustion chamber? Or are you talking about using the CO2 to spray onto and cool down the IC, which by definition is OUTSIDE the intake stream...and just chills down the IC from the outside...

This is a copy of a thread I replied to a month ago. I had a 350z (till 4 days ago when I sold it) and yes, the cryo cooling is good for a bump in HP - especially on warmer days like we're having now mid 80's with high humidity. Cooler dryer air compresses better than warmer moist air. The systems are relatively inexpensive and easy to connect, I'm not going to be the first kid on the block to try it though. For my Z it worked well - as far as the 335i goes - this is all new to me at this point.
Peace, Dean |

I'd completely forgotten about this thread. Thanks for the resurrection. This mid-atlantic heat wave is completely out of hand. Last week, 5 of 7 days had the national high temp in VA or NC

How could a sudden loss of temperature happen during normal conditions? Well, like crashing to the freezer. Anyway, my point is - there is a pretty high possibility the car's management isn't ready to handle s/t like this, why would it be, right? So a sudden major drop in temperature, causing exponentially more oxygen in the intake, logically not followed by an adequate reaction of the ECU, can cause the engine running lean. So? |

That's not possible. CO2 would seize an engine if it was sprayed into an engine. It sprays onto the fins of the intercooler, cooling the outside of the enclosed unit so that the air that goes through the IC is cooled down. |

I'm going to go ahead and buy a CO2 intercooler spray bar system and put it on. I'll post the results next time I go to the track.

Correct, otherwise we could breathe CO2 and extract oxygen from it...

Correctamundo...but they also "exhale" oxygen...
Hey, maybe we should grow plants in our intakes!

yea i said i didnt think it would, i know it doesn tunder normal circumstances, but shit does weird things under pressure and high temp
if i remember correctly though from chem class way back in the day c02 is one of the stronger bonds out there |
