There is no denying that the Power Stroke diesel is a great engine. It delivers a ton of torque, is reliable as all get out, and can run for a million miles if properly cared for. However, there are some ancillary components that are not as durable (ahem, CP4 fuel pump). But another issue that we have heard about from several Power Stroke owners concerns the turbo tubing.
Where they connect with the turbo is a plastic sealing ring that eventually gets dry and brittle. Once this happens, it no longer seals around the turbo and your boost goes away as it leaks around the seal. Then there is the issue we’ve heard about of the tubes cracking over time. I know that sounds strange, but, since Ford chose to use plastic to make the tubes, it’s no surprise. While this keeps weight down, how long do you think the tubes can survive in a heated environment? Eric Bacon of Lakeland, Florida learned first-hand what happens to the tubes over time, the plastic cracks, and the seal at the throttle valve hardens and then allows boost pressure to leak out.
Installation of the tubes is a really straightforward process. Simply remove the factory tubes, install the silicone hose pieces to the Pusher metal tubing, and secure the parts with the stainless band clamps. We started with the hot-side tubing.
In case you don’t remember, we recently added an S&S Motorsports Disaster Prevention Kit to Eric’s truck and that is when we noticed the cracked tubing. We couldn’t let it go, so a quick call to Pusher Intakes got us a new set of better-than-OE hot- and cold-side tubes for his 2011 Power Stroke.
Getting Started
The first thing we like is the Pusher Intakes’ turbo tubing is, it doesn’t violate any emissions laws. Let’s face it, it does not alter anything, it just looks better and helps smooth airflow into — and out of — the turbo. The TIG-welded-steel 3-inch cold side charge tube comes with an anodized throttle valve adaptor with a titanium finish. It looks good and will stay that way for a very long time. The tubes also include all-new HD silicone connections and full stainless T-bolt clamps. When installed, this setup is proven to hold compound turbo system boost levels.
Many aftermarket tubes use an abrupt beveled end that can make installing the silicone tubing difficult, Pusher Intakes has developed a proprietary machine that creates a gradual bevel to make hose installation much easier.
