Power and Beauty - Pulleys, Headers & Intake

Here is a side by side of the stock manifold and the JBA header. JBA's headers keep the exhaust impulses from interacting with each other until they get to the collector, unlike the factory unit that has them interacting at different times after they leave the head. This cuts down on turbulence created and in turn improves flow and efficiency.

Now the shorty headers were slipped right in. JBA did such extensive R&D on these pipes that they had a factory fit; nothing hit or had to be massaged with a ball peen.

Once all the provided bolts were installed, we tightened them all up. Once everything was done, we came back and retightened these after the engine had heated up and cooled down a few times.

Moving on to the induction, the factory intake setup and the throttle body was removed. All the intake pieces were boxed up and stored, except the hat (this will be reused with the STS intake).

Here is the bored and smoothed STS throttle body. As you look down the hole you can see the clean path the air has.

Here is the factory butterfly and the restrictive scoop attached to the bottom. It doesn't take a rocket scientist to know why removing this will increase efficiency at wide-open throttle.

All the cable and lines go back on to finish this part of the install. One thing to make sure you have is wide-open throttle. Have someone get in the truck and step on the gas. If you can open it more with your hand, adjust it out.

The hat pops back on to the throttle body and the new silicone coupler fit on that.

Now the tube assembly is installed. Not pictured is the mass airflow meter that was removed from the stock stuff and slipped between the filter and tube.

The weight of the filter is supported by a little bracket that bolts to the alternator bracket and slips under one of the hose clamps.

Here you go. As you can see, the engine compartment looks killer with all the new power parts and we also have more ponies to boot. Say hello to the shine and goodbye to the rear tires.
