UT Austin School of Engineering Assesses Performance Benefits of PTP Turbo Blankets' Automotive Turbocharger Heat Management System

The University of Texas at Austin recently took up the project of scientifically evaluating the performance benefits of the turbocharger insulation product made by Austin-based PTP Turbo Blankets. The analysis was performed by Graduate Research Assistant Steffen Bickle, and was approved by the Head of UT Austin’s Engines and Automotive Research Program at UT’s Cockrell School of Engineering, Dr. Ronald Matthews. The analysis they performed provides PTP with an unbiased assessment of their products by one of the top automotive research and testing facilities among American universities. The report, Performance Improvements of Turbocharged Engines with the Use of a PTP Turbo Blanket, focused on PTP’s current line of turbo blankets. The analysis by UT Austin was initiated in 2013.

Dr. Ronald Matthews and Steffen Bickle reported back with their findings on the performance gains attributable to installing a PTP turbo blanket on a turbocharged engine in April of this year. The project was initiated by Steffen Bickle, who was seeking a thesis project for his Masters degree in Mechanical Engineering. He had previously been an engineer for a turbocharger manufacturer and heard about PTP’s vehicle-specific turbo blankets, which insulate the turbine section of automotive turbochargers. Bickle discovered a lack of automotive engineering technical reports on a device such as a turbo blanket. Understanding the significant heat loss experienced at a turbocharger’s exhaust turbine, he proposed an engineering evaluation of the performance benefits of our turbo blanket. His research supervisor, Dr. Matthews, who has worked in engine and vehicle research for 35 years, agreed as waste heat recovery has become a major research focus in recent years. The turbo blanket solution from PTP seemed to provide a viable insulation technology to help prevent the loss of exhaust energy through the turbine walls of the turbocharger. Matthews and Bickle conducted engine tests with the PTP turbo blanket mounted on a 6.7 Liter Cummins turbocharged engine to obtain experimental proof of the potentially increased turbo boost performance.

In the report, Matthews and Bickle show that the turbo blanket by PTP considerably improves turbocharger and thus engine performance. The researchers point out that, “…[t]he turbo spooled up more rapidly with the turbo blanket installed in comparison to the baseline configuration,” and that “…[i]n all cases [PTP turbo blanket usage] resulted in an improved boost performance in the intake and a significant time-to-torque advantage of the engine . . .” (p.V) Matthews and Bickle further state that their measurements “showed that the key feature of the PTP Turbo Blanket was improvement of turbocharger performance and engine acceleration which will result in improved vehicle acceleration.” (p.31)

This is big news for PTP Turbo Blankets, as one of the world’s most influential automotive engineering testing facilities has now validated the company’s performance claims. PTP Turbo Blankets’ line of turbo blankets were also shown by UT to significantly reduce the likelihood of heat damage to components in close proximity to the turbocharger, validating another of the company’s major claims.

PTP Turbo Blankets manufactures and sells a variety of automotive thermal management products. The company is headquartered in Austin, Texas and has been featured in multiple publications and television shows, such as Import Tuner Magazine, Two Guys Garage, All Girls Garage, and Car Fix: High Performance Road Trip.

PTP is looking forward to attending SEMA 2014 with their project Viper.
