Hey guys i have a V-1 S-trim and i it is so quite you can barely hear it at an idle. It works fine and produces 12lbs of boost no problem. I know its not a sc-trim or an sq-trim so i dont no why it is so quite anybody have an idea?
The blower data plate should say V-1 or V-2... Like mentioned above, if you bought it used, it could have been sent back & rebuilt with helical gears, like the V-2's(SQ's)
