Tony D Posted August 10, 2017 Share Posted August 10, 2017 (edited) Rayjay external wastegate worked OK to limit boost to around 12 psi.It was connected off the brake booster line with a "T" before the check valve. A boost controller in that line usually had a bleeder hole upstream from the ball-check adjustable controller and the wg actuator...You definitely want to limit it, that turbo will go to 21 psi without a problem, and quicker than you think!The hole was for the carburetor de-icing on the Carter YH that normally bolts to the front of that turbo. In cold or even cool areas with any kind of humidity at partial throttle, especially off-idle the original one-barrel would ice up like a big dog without exhaust heat circulating through that tubing and connected to those two holes! Carb sucked air in from the air cleaner, through that base plate, and through the carb base. Welcome to using parts from non-watercooled engines! ;^P Edited August 10, 2017 by Tony D Quote Link to comment Share on other sites More sharing options...
