In this work the method of computer modeling solved the problem of reducing the efficiency of the turbocharger associated with the mismatch of the geometry of the resulting casting petal turbine technology geometry, calculated gas-dynamic calculations. Computer methods was calculated crystallization of the casting and hardening of the stencil. Computer simulation showed that there is a significant change in the geometry of the turbine blade, which adversely affected the geometry of the resulting casting. Was proposed and solved by the method of computer simulation of "reverse" task of the task of such a geometry of the mold, the solidification of the stencil in water and its deformation led to a (given) geometry of the resulting casting of the turbine of the turbocharger. The solution of this problem by the method of computer modeling allowed to reduce the production defect on the discrepancy of the turbine blade geometry of the turbocharger by 90 %.
