26-6/8 Turbo Charger update:
ASR268 St-3 Bell Choke and Diffuser Installation.
Titanium Compressor Nut (MRL)©
Basic Specifications:
-> Turbos are built in stages 1 through 3.
-> Stage 3 Turbos being highest in development and refinement.
-> Linear and Bell replaceable chokes and diffusers.
-> Anemometric Analyzed Flow and Pressure.
-> Highly refined geometries.
-> Radius Linearizer (MRL) for Bell choke St-3.
-> Anodized To color indicate refinement stage and type.
-> Much higher tolerances. We take this very serious, +/- .00012 serious.
-> Machine from solid, gone is the porous cast alloy for these critical parts.
-> Perfect fit and Flanged Coupled for heat exchange.
-> Titanium Compressor Nut (MRL)
Why? Several reasons. Simply stated, KKK use standard production practices.
4451 ASR use toolroom practices and are unlimited by cost of materials.
4451ASR Cycling Valve:
(Intentionally delayed as part of Turbo/Wastegate update.)
These solids will be replaced with the real part soon.
Basic Specification:
-> Multiple Jet sizes
-> New Potting Compound
-> Custom Viton Seals (in house)
-> Limited Service abililty
-> New port and vein geometry
-> New surge chamber
-> 3AN to waste gate
-> Al Alloy Chassis
4451ASR Waste Gate Actuator:
(Rapidly moving forward.)
-> Single ended - Vacuum OE replacement
-> Differential - Vacuum & Pressure
-> Direct partner to the 4451ASR Cycling Valve
-> No Shimming Required - appropriate spring preload.
