Product description
Add more turbine Flow to your he351CS. The HE351CW is quick spooling, but at the expense of high egt and drive pressure when you get above about 425hp with the stock 9cm turbine housing. The 60mm compressor can support 500hp, but the turbine wheel chokes.
Installing a 12cm turbine housing will result in a reduction of drive/back pressure similar to installing a 64mm turbine. Unline a turbine wheel replacemennt, there is no rebuild or balancing required.
Actuator is not included.
