I drilled 6 .125 holes in the flange of several sets of 160 modern stats and they still
run up in the 200 range when it gets 90 outside. These tests were done on a 39 pick up that will run at a fast idle for 2 hours on a 100 degree day and never get over 180. Bob Shewmans hi flow stats are the only ones I know of that work. G.M.
