Turbo Flow Rate - Infomation Thread
Hi Guys, This may have been done before but can't find any threads so thought I would post my own. I have been searching for a turbo suitable for my build for the past few weeks, in my search I have gathered flow rate info on a lot of turbos ranging from standard to 1000bhp capable. There may be a few missing and some info may need changing but feel free to add and correct. After all input I would like to have a full list of turbo's and flow rates to help anybody who is trying to decide on a turbo.
