Message: [QUOTE="Cold Roller, post: 635177, member: 9551"] They run a flow check with air to determine initial calibration. typical new nozzles flow about 170-175 l/min. Then it is just a matter of time. They run 3-5 cycles of varying time (depends how fast it changes the flow) of an abrasive medium through each injector nozzle to determine the standard. So, for 75% nozzles they would flow about 305 l/min when done (295 - 315 for mine). Older nozzles are harder so the first pass is usually twice as long. As long as the nozzles close properly, they basically become new again at the new flow rate. If you can afford to have the truck down while you wait or during the DIY build, no problem. EDM is the other method used to make new or larger holes. You can get nozzles from a few companies including, some of the sponsors plus a few others such as renegade diesel (facebook), Lubeowner, Elitedieselengineering. Prices are $480 and up. You should know that every group selling different nozzles flow rates them differently. So brand X 75% over may be the same as brand Y 60%. In any case, 175s or less only need 50% at most for min time max PW flow. The same argument could be made for 190s as well, but at some point you need a larger nozzle. 75% nozzles or larger will mean haze at lower engine RPM if the turbo is not spooled or fuel is not pulled in the tune until boost/MAF is increased.
