Treadstone Performance Engineering is once again is proud to announce the release of their famous flex couplers in two new sizes 3.50" and 4.00".
Flex couplers are used to isolate engine vibration to your exhaust components, and prevent cracks in your downpipes, cat-backs headers and turbo manifolds. We have introduced Stainless Steel Flex Couplers that have bellows with interlocking lining to help increased exhaust flow through the coupler, and prevent excessive back pressure to build.
Standard flex couplers either have a braided inner liner that in time will burn out creating an obstruction in the exhaust track, or others with a flex bellow that creates turbulence when exhaust gases flow through. These are the only type of flex coupler that can withstand high pre-turbo exhaust temperatures, meaning you can use these flex couplers when complex turbo header designs are needed to prevent turbo header cracks. Perfect for turbo downpipes! We use these in our WRX turbo kit up pipe!

How They Work?
There are two of the most common types of mass airflow sensors, the vane meter and the hot wire. Neither of these sensor designs measure air mass directly, but in conjunction with other additional sensors and inputs, the ECU can determine the mass flowrate of intake air. Both of these sensors output a 0.0�5.0 volt signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature sensor incorporated into their housings. This allows the computer to access its array of equations to determine the actual rate of flow entering your engine.
Their Importance!
So what does all of this mean? All of this equates to a simple setup, since the factory ECU was embedded with predetermined set of equation and parameters, when those parameters are changed without a recalibration to the ECU the end result is an undesired one.
i.e.: if the factory air intake was setup for a 2.5� inside diameter pipe and a customer replaces it with a larger 3.0� diameter pipe. The incoming air velocity slows down due to the larger area in the tube, the MAF will then send a lower voltage and read less air going into the engine then there actually is, and the end result would be a leaner air/fuel ratio that may cause per-ignition/detonation, melted pistons, or worse destroyed engine.
Larger diameter pipe will cause the engine to run lean without recalibration of the ECU!
On naturally aspirated engine, some manufactures will increase the size slightly on cold air intakes, without retuning, because a N/A car makes more power when it runs leaner. But, care must be taking on forced induction engines, because running leaner can have a much more catastrophic effect!
Conclusion
When changing or upgrading a component on a modern internal combustion engine the proper step must be made to insure the change is done safely. The most important rule to remember is, tuning is king!
Many may argue it the difficulty of finding compounds that can safely run E85 without the dreaded gumming and decay associated with it. As many of you may have heard the rumors of Walbro releasing an E85 compatible version of the 39/50 DC/SS pump many people have come to know as the 400LPH pump (P/N: F90000262) well Treadstone Performance Engineering is proud to announce the rumors were true and the E85 Version of the 39/50 DC/SS pump was released in Spring (P/N: F90000267). This new pump will be fully E85 compatible in comparison to the F90000262.
In overall appearance the pump dimensions are the same, for the F90000267 unit to be used in E85 Walbro took a number of steps most notably being all electrical connections were sealed, and a built in electrical harness with a female Packard connector attached to the far end of the unit. There will also be a release of the male Packard connector with flying leads so there will be no chance of a reverse wiring error while keeping the connection sealed. Walbro also changed the chemical composition and setting process of the polymers used in the construction of the unit to allow them to resist the plastic decay associated with E85, as well as the metal coating used to protect the outside of the case.
