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
