The “Dynomite” turbocharger kit by Evolution Powersports is a complete direct replacement turbo system which incorporates a new high efficiency cast header/exhaust housing built specifically for the 925CC Polaris Prostar engine. The new turbo features a divorced flow exhaust housing to help maximize flow as it exits the turbine. The high flow compressor wheel, compressor cover and OEM like CHRA makes this the ultimate XPT upgrade. The EVP Dynomite turbo system was designed to extract the most power from a stock XP-TURBO engine while producing excellent turbo spool characteristics. The Dynomite turbocharger provides instantaneous boost response with an intense amount of top end power that never fades. This upgrade is an excellent option for those who want to maximize the power of a relatively stock engine which utilizes existing EVP upgrade components. EVP designed the Dynomite turbocharger exhaust outlet mounting flange identical to stock so any exhaust system that worked with the stock turbocharger can be reused with the Dynomite turbo. 

Evolution Powersports spent a considerable amount of time refining the Dynomite turbo systems for maximum flexibility with various different octane fuels. NO hardware or wastegate changes are needed when switching between tunes – simply siphon out the old fuel, install the desired fuel into the tank and reprogram the ECU with your custom flashing tool (clutching adjustments may be required to maximize performance on a given fuel).  The 91 Octane tunes deliver more power at less boost pressure than any stock injector, stock turbo tune.  EVP has designed the 91 Octane tunes to be used for trail riding or duning – they are NOT intended for racing. With the 110 octane and E85 tunes, the full potential of this turbo system is unleashed with a jaw dropping 260-270 HP!
