Performance Diesel Inc. is proud to introduce the latest in turbo technology! PDI’s patented nozzle ring technology provides truckers with the competitive advantage because it’s tune-able and it’s the most efficient turbo on the market! This new technology gives you the edge with quicker throttle response and cooler exhaust temperatures.
There are many advantages of this new nozzle ring Big Boss® turbine housing over a standard turbine housing and furthermore over the variable geometry turbo found on most newer engines.
The PDI nozzle ring turbo takes advantage of not only exhaust pressure, but also the exhaust gas velocity to spin the turbine wheel allowing the turbocharger to spool up much quicker with less exhaust turbine drive pressure than a conventional turbocharger or the newer variable geometry turbocharger.
So what makes this patented technology more efficient? The new PDI Big Boss® turbocharger has a very large turbine housing A/R, which lowers exhaust drive pressure. This would normally make the turbocharger spool up much slower, but with the implementation of the nozzle ring with perfectly angled vanes that direct the exhaust gasses at the perfect angle just off tangent of the turbine wheel.
The turbocharger spools up much quicker with less exhaust drive pressure than the factory turbocharger. This patented technology makes the PDI Big Boss® turbocharger far more efficient and reliable then a stock turbocharger.
The nozzle ring turbocharger places nozzle vanes at the perfect angle of efficiency. The number of nozzle vanes that the nozzle ring has determines the effectual A/R of the turbine housing. For example a 13 vane nozzle ring has a smaller effectual turbine A/R. The 11 vane nozzle ring has a larger effectual turbine A/R.
The beauty of this turbine housing is that the nozzle rings are interchangeable without removing the turbocharger from the engine. By removing the final exhaust v band clamp and the v band clamp that holds the nozzle retainer ring in place the nozzle rings can then easily be changed.
With this new Big Boss® turbo the most noticeable difference an owner operator will see and feel is the quickness of turbo response along with the increased fuel economy and the ability to pull the engine lower in the rpm range without turbocharger surge. PDI is proud to add this new turbo to its line of Big Boss® products.
