The  LIPP Boss Turbine Housings are produced from a cast Stainless Steel alloy that utilizes investment casting process that will endure the extreme temperatures that  turbocharged engines will dish out.  The Stainless Steel Alloy used will help reduce under hood temps by containing the heat within the housing to ensure faster spool up without further damaging surrounding components.
 
 

 Comp Turbo Inc. announces the availability of its new Model CT3B turbocharger, applicable to both automotive, diesel, and gasoline passenger car engines. The performance of the new CT3B Turbocharger is enhanced by a unique proprietary arrangement of ball bearings that maximizes mechanical efficiency and allows a rapid increase in turbocharger rotor speed when a vehicle is accelerated. A rapid increase in engine air supply during acceleration can result in an increase in engine operating efficiency. The new Model CT3B is a patented triple ball bearing duplex turbocharger. This triple ball bearing turbo runs a (DB) duplex pair of ceramic bearings on the compressor side to keep the bearings in preload.

Why preload bearings?


Bearings are preloaded for the following reasons:

  • Eliminate radial and axial play.
  • To reduce noise during operation.
  • To improve positioning accuracy.
  • To reduce the possibility of damage from vibratory loading.
  • Lessen the difference in contact angles between the balls and both inner and outer rings at very high speeds.
  • Prevent ball skidding under very high acceleration.
  • To increase life and axial capacity.

 

 
 

 

 

 
 
 
 
 
  This configuration is suited for most applications having good alignment of bearing housings and shafts it is also preferable where high moment rigidity is required, and where the shaft runs warmer than the housing. (Figs. 3a and 3b).Inner ring abutting faces of DB duplex bearings are relief ground. When they are mounted and the inner rings clamped together, the load lines (lines through points of ball contact) converge outside the bearings, resulting in increased moment rigidity.”
 
This, combined with a floating turbine bearing under preload, allows the turbo to keep all three bearings in light preload when the turbine shaft grows due to increasing exhaust temperatures .This allows the Model CT3B turbocharger to be more stable at high temperatures where it operates best. Making this model CT3B turbochargers triple ceramic ball bearing center pack able to take the largest thrust loads and disbursing the loads which increases the spool characteristics and allow the turbo to build boost much faster than a conventional thrust bearing turbocharger allowing the motor to make more power at a lower RPM or run a larger turbo without jeopardizing the spool characteristics you like. All of these CT3B turbochargers are fully serviceable rebuildable and can also be upgraded.
 
 
 
CT3B Ceramic Ball bearing systems Vs. Conventional Sleeve bearing systems

CT3B ball bearing technology results in several important performance improvements compared to a conventional sleeve bearing systems. One important advantage is that the CT3B model turbocharger can carry both axial and radial loads so that the need for a conventional thrust bearing is eliminated. The power loss attributed to a conventional thrust bearing is proportional to the fourth power of the radius and can amount to several horsepower at the high speeds at which turbochargers operate. The CT3B is capable of carrying both high thrust loads and radial loads at the same time and usually absorb only fractions of a HP due to the anti friction characteristics.

Conventional Floating sleeve bearings have an inner and outer oil film fed by lube oil under pressure from the engine lubricating system. These oil films have significant viscosity and produce significant friction losses due to oil film shear when a turbocharger rotor is accelerated and running at high speeds. These Power losses combined with the thrust bearing power loss, result in mechanical efficiencies in the middle 90% range in conventional turbochargers. In comparison, the mechanical efficiency of the CT3B can approach 99%. This high mechanical efficiency contributes to turbocharger rotor acceleration rates that appreciably faster than turbochargers using sleeve bearing systems. The acceleration rate of the vehicle using a CT3B turbocharger is enhanced and moves the engine out of inefficient operating regimes more rapidly. An improvement in the number of miles per gallon of fuel used is the usual result when a vehicle is equipped with a turbocharger using ball bearings than sleeve bearings.

Under steady state operation, the lower HP losses of ball bearings means more turbine power is available to the turbocharger compressor and this results in a higher engine intake manifold pressure. In most cases, this can make an additional contribution to improving engine fuel consumption.

The CT3B uses ceramic ball bearings for a number of very significant advantages over steel ball bearings. Ceramic balls are 60% lighter than steel balls and operate with lower vibration levels. Since centrifugal forces are significantly reduced at high speeds, their service life is two to five times longer. There is less heat build-up in the ceramic bearings during operation and they can reach operational speed up to 50% higher than steel ball bearings. These favorable mechanical characteristics of the ceramic ball bearings make them an ideal choice for turbocharger bearing systems that run at high operating speeds and are subjected to high exhaust gas temperatures.

Improved oiling- reduces oil flow in GPM (gallons per minute) while maintaining adequate lubrication.  Also, lowers oil pressure drop across the turbocharger.

 

 BOSS SERIES turbo's use both oil and coolant for the utmost in durability.

 

Compressor Wheels:

 

            All compressor wheels produced by ITS are made of Incolnel for it’s light weight, strength and durability.

 

Compressor Housings:

            Compressor housings are offered in either a T04E or GTS (GTS available starting at the Stage 4 level) option polished or unpolished. The T04E housing has a 3” inlet and 2” outlet while the GTS housing has a 4” inlet and a 2.5” outlet.
