Also Sometimes when cars gain good HP From an IC chiller it is because some of the CO2 is being sucked into the intake and acting like Nitrous.
Its sprayed before the run and not during the run. a single five second spray of the c02 will chill out the I.C. I have read articles where on 5 second spray was done then 5 consecative dyno pulls with no sprays inbetween. Each pull
the dyno dropped by 10 hp. A single fresh spray will give you 10% more wheel hp.
So 25 to 30 whp on a hot day is doable on the 335I
a ten pound tank will give you about 150 seconds of spray time so about 30 5 second shots.....Co2 is cheap ......its a good mod
