Description
Stage 1 75/96/1.32 with a cast compressor wheel, Race cover, V2 turbine shaft, 360* steel thrust bearing. This unit works excellent on stock to 550HP. With a tune you can expect similar spool to the much smaller K31 charger. Because these units come into power earlier than a standard 171702 you can expect up to .5 MPG increase with good tuning.
Stage 2 75/96/1.32 with a billet 6 blade compressor, Race cover, V2 turbine shaft, 360* steel thrust bearing. This unit will spool nearly identical to the stage 1 but will have more flow from the compressor wheel. This unit is great for those 550-650HP tractors. Because these units come into power earlier than a standard 171702 you can expect up to .5 MPG increase with good tuning.
Stage 3 78/96/1.32 with a billet 6 blade compressor, Race cover, V2 turbine shaft, 360* steel thrust bearing. This units will be slightly laggier and have the possibility to surge more due to the more aggressive compressor size. This unit typically will see better results from a 14L but is still usable on a spicy 12.7. Should be considered on engines making over 650HP.
