Jp Magazine – October 2019

The ninth and final major step in the

ProCharger supercharger installation

was to double-check and secure all PCV

hoses, swap in the new kit-supplied

MAP sensor and MAP adapter, and hook

up all the electrics, such as the alterna-

tor, air pump, and battery.

The before (stock) and after (modified) installation dyno graphs clearly show the

gains in horsepower and torque from the

ProCharger supercharger kit. A quick drive after

the installation gave us a very positive seat-

of-the-pants impression of the altered perfor-

mance output of the ProCharger-upgraded 3.6L

V-6 in this 2018 Jeep JL Wrangler. There were

big smiles on all of our faces.

Putting together and hooking up the air inlet
and filter system to the ProCharger head unit
was next. A bit of “clearancing” had to done
on the fan shroud to get the air inlet tube to fit
in. The^5 ⁄ 8 -inch PCV hose installed earlier was
connected to the^3 ⁄ 8 NPT x^3 ⁄ 8 -inch 90-degree
hose barb installed in the center tube of the
air inlet system.

Seventh in the nine major groups of installa-
tion steps on the way to having a ProCharger
supercharger on this 3.6L V-6 engine is
putting the PCV system back into play.
Reassembly involves reconfiguring the PCV
hoses and adding a kit-supplied vacuum
manifold that connects to the throttle body
and supplies vacuum to the brake boost
system and the new surge valve.

The surge valve and its filter were installed so
they were clear of any moving parts, the valve’s
barbed fitting was oriented so later it could be
reached by a vacuum line coming from the new
kit-supplied vacuum manifold, and we made
sure the valve linkage was unobstructed. Then
the valve was zip-tied to the frame.

Of course, some final reassembly

(such as reinstalling the front grille)

was required, as well as filling up

with high-octane gasoline before

we could testdrive the newly

ProCharger-supercharged 2018

Jeep JL Wrangler Unlimited Rubicon.
