  • Turbo Charger

    Anyone put one of these on a 289? Just curious what was used. Not a real serious question.

    "The Chicken Hawk's twin-turbo Studebaker 299 engine (a 289 with a .060 overbore) has never been on a dyno, so I can't verify anything other than what those formulas used to calculate HP from weight, ET, and speed have to say. Using these, it is about 670 HP, but maybe it would be more on a dyno. According to the formulas printed in a recent Hot Rod, it takes 600 HP to push a 3500-lb weight to 130 MPH in a quarter-mile, and 672 HP to push it to 135, which the Chicken Hawk has done. . . and it weighs about 3600 pounds! Those figures cited are supposedly at the rear wheels. Engine dynamometer readings should yield even higher figures without the drag of the drive train that rear-wheel horsepower figures necessarily include, although I understand some of the newest dynamometers can simulate rear wheel horsepower. And remember, all those figures are with two old AFBs getting air pushed through them by twin turbos."

      Ted Harbit has twin turbos, Jim Lange's Avanti has em too. I think we also have one over there with a Lark with a single turbo on the Racing Studebaker's site but for the life of me I cannot find nor remember his name. I think I asked Ted at one time about his turbos and he said he used TO4's on his Chicken Hawk. I know they were larger than the run of the mill T3's(Larger turbo, larger scroll) as he didnt want to overrun the turbo. Basically they were Grand National turbos(around the same size, but larger), but not Grand National turbos.

            The turbos on the '51 (Chicken Hawk) are TO 4's and were originally for a Case tractor. Had to change the wheels and experiment with the exhaust housings some to get them working reasonably well. The Avanti will have basically the same thing.
