Switchblade and Big Rig Power

OWN THE ROAD WITH THE SWITCHBLADE TURBO

You told us you wanted more power, more performance and more fun – we heard you loud and clear! Big Rig Power is excited to have added the Switchblade to our Own The Road product line. Developed by Blaylock Turbochargers, the Switchblade is a VGT that has the convenience of spooling up like a small turbo that can open up like a large turbo.

HOW DOES IT WORK

The vane in the Switchblade makes it take off like a small A/R turbine housing (8 psi) and then opens at a pre-set boost pressure, making it perform like a significant turbine housing. This patented technology replaces stock configurations with a larger turbo while reducing the time required to generate boost under low flow conditions. By doing this, the Switchblade significantly increases engine efficiency, flow, lower EGT’s and performance.

 

SWITCHBLADE VS. OEM ELECTRONIC VGT TURBOS

 

The Switchblade system overcomes several complications we see with VGT turbos by eliminating a large number of moving parts and reducing it to an externally actuated single blade. The blade is entrained in the exhaust system (hot side) and attached to a solid shaft, making it nearly impossible for the system to become stuck or fouled by carbon deposits.

The Switchblade can be adapted to fit almost any application, providing the benefits of VGT performance without the maintenance and electrical concerns of OEM stock turbos.

 

FEATURES

  • Starts to Spool up at 8lbs (Better Low-End Boost). No Turbo Lag.
  • Cuts Down Smoke Through Stacks, More Air Flow.
  • Vein Opens and Closes Between Shifts Which Changes the A/R Ratio on the Compressor Side
  • Air Actuator and Turbo Combination is Self-Contained.
  • Re-enforced T6 Turbo Flange Fit for Most Aftermarket Exhaust Manifolds.
  • Hot side/exhaust ceramic and nickel coated for better heat dissipation.

THE SWITCHBLADE IS COMPATIBLE WITH:

 

  • On-Highway Vehicles
  • Detroit 60 Series DDEC 4/5/6
  • CAT C13/C15/C16/C18
  • Cummins ISX Series 870/871/2250/2350
  • Off-Highway Vehicles / Agricultural / Marine / Industrial
  • Any engine fitted with an aftermarket exhaust manifold utilizing a T-6 flange. (The turbo actuator combination requires extra space)
SIMPLER, AND MORE EFFICIENT THAN ANY OTHER TURBO DESIGN ON THE MARKET

Jim Blaylock on the Switchblade

 

“I came up with the idea of the Switchblade turbo when I started noticing more and more VGT turbo’s of other manufacturers coming through our shop for repair. Becoming very familiar with the different designs and their extreme complexity I thought, “there has to be a simpler way to accomplish the same results”. One day while cleaning a turbine wheel with solvent and blowing it off with an air nozzle I started noticing how I could vary the speed of the spinning turbine wheel by manipulating the air nozzle. This led me to start thinking about using one extra moving part versus a fixed geometry turbo to build a simpler VGT turbo with much less complexity and less moving parts to fail while significantly increasing engine performance.”

How the Switchblade Works
Switchblade How It Works

The principle factor influencing the impressive performance enhancement of the Switchblade turbo design is the ability to take a larger than normal turbine housing and get it to spool up quickly like a smaller turbine housing and then to open up and to perform like a large turbine housing in the upper engine rpm range. This is accomplished by using a single vane to pinch down the volute (exhaust gas passage to the turbine wheel) there by taking the low flow and pressure of the exhaust gas at lower engine rpm’s and increasing the gas pressure impacting the turbine wheel. This results in quicker spool up getting increased oxygen into the cylinders quicker and more completely and efficiently combusting the fuel charge. The results are much quicker low engine rpm torque and decreasing exhaust particulates (smoke). As the boost increases the vane automatically starts to open reducing back pressure and then the magic of the larger turbine housing at higher engine rpm appears.

On takeoff, the vane is closed pinching the exhaust flow down to the smaller end of the turbine housing scroll before it can impact the turbine wheel with more force at lower engine rpm’s. Using the vane lets us use a larger turbine housing than a conventional turbo would need to get low-end performance and then open up the vane to get better top end performance with the bigger turbine housing.

When boost pressure hits a predetermined level the vane actuator starts opening the vane and allows more and more exhaust gas access thru the volute slot to impact more of the turbine wheel circumference. The vane opening decreases the exhaust back pressure letting the engine to take advantage of the larger turbine housing and breathe more efficiently.

The Switchblade Turbo is a very simple design performing like two turbo’s in one, NO nozzle vanes to change to suit different driving styles, vane operation is automatically self-controlled.

Proven Technology

The graphs to the right illustrate the impact that the Switchblade has on the performance of the turbo. There is a traditional trade off between quick spool up times and top end performance. A smaller housing enables the turbo to generate boost more quickly; however, creates engine back pressure under towing or heavy use conditions. The Switchblade uses a significantly larger turbo than the stock configuration and is able to spool up quicker due to the directed flow over the turbine tips. Note the difference in back pressure and boost pressure between the Switchblade and the stock with similar spool up times. This reflects the turbo’s ability to respond quickly from low flow conditions and still provide vastly superior perfor- mance under heavy use conditions.

Fuel Savings

Data was collected every Friday over a period of 3 months. The data was averaged over the 3 months resulting in a average mpg of 7.2. The pre turbo upgrade data was gathered over a 3 month period leading up to the turbo upgrade. The turbo upgrade improved mpg from 6.1 mpg to 7.2 mpg a ~15% improvement.

The horsepower and torque lines on the right side of the graph are an S363 turbo without the Switchblade vane. The horsepower and torque lines on the left side of the graph are the same turbo with the Switchblade vane.

All other factors such as fuel, tuning were untouched, with the vane being the only variable.
