The R-73 9.85 Sportsman is Precision’s larger-frame class-legal turbo for NHRA 9.85 index racing. 73mm Next Gen CEA wheel matched to the class-legal turbine and housing combination — the spec the tech inspector checks every time the car runs the index.
73mm Next Gen CEA wheel. The Sportsman class spec defines the wheel size, turbine pairing, and bearing system. Picked because the rule book requires it, scaled for 9.85 builds making more power than the smaller 67mm 9.85 platform.
Dual ceramic ball bearing CHRA. Class-legal bearing system rated for sustained 9.85-class race duty across full-throttle pulls.
Choose from Turbine Housing: SPORTSMAN SS V-BAND, SPORTSMAN T4 4-BOLT; A/R Ratio: 1.12, 1.28, 1.00, 1.15 A/R turbine housing options to match your build’s spool vs top-end priorities. Use the dropdown above to configure your exact build — SKU and final spec will update as you select.
If your 9.85 build needs the larger Sportsman frame, this is the part. Hand-built in Hebron, balanced, and backed by Precision’s 1-year warranty.
