these aren't the same smokey exaust engine Mig-29s.... Engines are different... RD-33MK version of the RD-33 engine...

The Indian Navy versions will be powered by the new RD-33MK afterburning turbofan developed by NPO Klimov in St. Petersburg. The RD-33MKwhich is due to enter production at the Moscow Machinery Enterprise named after V. V. Chernyshov, is a derivative of the production RD-33 Srs 3 which has been powering the MIG-29SE and the MiG-29SMT since 1995. It incorporates changes based on the experience gained with the RD-33K engine that powered the original MiG-29K and the MiG-29M; apart from the addition of full authority digital engine control (FADEC), the RD-33MK features revisions to the low-pressure and high-pressure compressors, the combustion chamber and the HP and LP turbines. This increased the mass flow by 6.5% and the turbine temperature by 40°K. The overall effect of these changes was to increase the thrust in full afterburner by 8% to 9,000 kgp (19,840 Ibst) and at full military power by 1% to 5,400 kgp (11,905 Ibst). The use ol a so-called smokeless combustion chamber has helped to address a perennial problem - the RD-33's high smoke signature which can be seen for miles, ruining stealth. Also, while retaining the 1,000-hour TBO of the RD-33 Srs 3, the RD-33MK has had the designated service life doubled (to 4,000 hours). ,
