High Flow Power Outlet
Ford 7.3L Powerstroke Diesel
Need to lose more exhaust heat? The EightySixd High Flow Power Outlet can easily reduce exhaust temperatures over 100 degrees for less than $200.00!
While upgrading your turbo or exhaust system, we recommend always installing a EightySixd High Flow Power Outlet on the turbo to replace the stock
outlet piece. This will eliminate the stock EBP valve on most applications, and further reduce exhaust backpressure even on a non-EBP valve equipped
motors. The stock outlet piece has three major flaws, all of which are remedied with this long overdue casting.
In most states it contains an electronic backpressure valve to aid engine warm up times. This butterfly valve is located at the worst possible position
as far as performance is concerned. It is right where the exhaust is exiting the turbo transitioning from high pressure pre-turbo to lower post turbo
pressures. This results in an expansion of the exhaust gas trying to occur right where it hits a huge restriction (the e.b.p valve). This is further
amplified by the fact that the exhaust gasses are exiting the turbine in a swirling vortex and hitting the flapper valve within inches of the turbine
wheel, further slowing exhaust flow. The EightySixd casting has no valve or provision for a valve!
The stock casting has a divider wall between the wastegate valve outlet chamber and the main exhaust outlet. This is a bad idea when trying to increase
exhaust flow because it forces the wastegated exhaust to back up before it can enter the main exhaust stream and exit the casting. Keep in mind that the
exhaust exiting the wastegate valve is coming out at a higher pre turbo pressure so when it has to reverse flow and try to enter the exhaust stream just
upstream of the e.b.p. valve, it certainly doesnt help exhaust flow! The EightySixd casting has removed this dividing wall completely.
Next is the inside diameter of the exhaust outlet. Stock is about a 2.8 i.d. with the very restrictive valve making its effective diameter much less. The
EightySixd casting is an unrestricted 3.2i.d., perfect for, and compatible with any performance exhaust systems with a 3.5 or 4 downpipe.
This exhaust outlet casting should drop exhaust temperatures about 150 degrees on a stock turbo and will optimize the exhaust flow with the EightySixd 7.3 turbo!
