Durability can be enhanced greatly by ordering the “TUFF-TURBO” option for your new turbocharger. The “TUFF-TURBO” option is available for all T4 series, 60-1, and 62-1 turbochargers. This TURBONETICS exclusive option utilizes O, P, or Q trim turbine wheel shafts, and the “stagger gap” piston ring. Specially developed for competition applications, the “TUFF TURBO” option includes the “big shaft” with a larger bearing structure, larger thrust bearing and a left-handed nut. The “big shaft” virtually eliminates the destructive shaft motion normally associated with high boost. The “TUFF-TURBO” option is available with dynamic seal only.

THE “Q” TRIM TURBINE WHEEL SHAFT ASSEMBLY
Recognizing the need for a higher flow capacity turbine to match the capabilities of the 68-1 and the “T” Series compressor wheels, TURBONETICS has developed the “Q” trim. Incorporating all of the features of the “Tuff-Turbo” option, the “Q” trim represents the largest diameter turbine wheel that can be mated to a properly machined TO4B turbine housing. The result is a 12-15% increase in choke-flow limitation which significantly reduces turbine backpressure.

“STAGGER GAP” PISTON RINGS - a TURBONETICS exclusive !
TURBINE-END PISTON RING OIL LEAKAGE HAS PLAGUED THE TURBOCHARGER INDUSTRY SINCE “DAY ONE”. CONVENTIONAL PISTON RINGS UTILIZE A STANDARD RING-GAP CONFIGURATION (SEE SKETCH) FOR EASE OF MANUFACTURE AND INSTALLATlON - SUCH RINGS, BY DESIGN, LEAVE AN OPEN PATH THROUGH THE EX-POSED GAP FOR ANY OIL REACHING THE GAP TO PASS INTO THE TURBINE SECTION - RESULT? - SMOKE, RAW OIL LEAKAGE, OIL CONSUMPTION, MESSY OIL TRACKS, ETC.. THESE PROBLEMS ARE FURTHER AGGRAVATED BY TURBO INSTALLATIONS WITH MARGINAL OIL DRAIN PROVISIONS, HIGH TURBO LUBE OIL FLOW, LOW OIL VISCOSITY/HIGH OIL TEMPERATURES AND LOW-MOUNTED TURBOCHARGERS.
THE NEW UNIQUE TURBONETlCS “STAGGER-GAP” PISTON RlNGS MINIMIZES THESE CONCERNS BY OFFERING A CLOSED GAP PATH TO ANY OIL ATTEMPTING TO ESCAPE FROM THE BEARlNG HOUSING. THIS SIMPLE BUT EFFECTlVE DESIGN IS ACCOMPLISHED BY A STEPPED-END CUT INSTEAD OF THE CONVENTIONAL THROUGH-CUT UTILIZED BY STOCK RlNG MANUFACTURERS. NORMAL PRESSURE DIFFERENTlAL BETWEEN THE BEARING HOUSING AND THE TURBlNE SECTION FORCE THE OPPOSING FACES OF THE “STAGGER-GAP” RING TOGETHER, THEREBY ELIMINATING THE OPEN PATH NORMALLY ENCOUNTERED.
“ STAGGER GAP “ RINGS ARE STANDARD IN ALL TURBONETICS PERFORMANCE TURBOCHARGERS AND ARE FULLY INTERCHANGEABLE WITH STANDARD FACTORY RINGS FOR ALL T2, T25, T28, T3, AND T4 PRODUCTION TURBOCHARGERS.
