ike I said above. It wont work if you use the nitrous nozzle. You MUST use the fuel nozzle. (i made the same mistake too) can you say Booooog?Quick6 said:Just a little FYI, NOS do not work well for water injection! They are made to flow a high pressure gas and not a low presure liquid! Use the proper part for the job and it will better and last longer. Trust me, we've tried!
