Below you will see a little bit of what is involved in building the LHT Performance Intercooler/manifold. It starts out as a stock Jackson Racing Blower manifold, and is cut and modified to perform even better in both on and off track conditions. The end result flows more air, is less constrictive, and cools the charge coming out of the blower by an average of 120 degrees.
Above Left: Stock Jackson Racing Blower Manifold Intake Port
Above Right: Ported Intake Port opened more to allow unrestricted airflow. The port is also tapered in to the plenum to produce more velocity.
Above Left: Shows the stock manifold where there are large pieces cast in to the manifold right in the way of the air flow.
Above Right: Shows What the same area looks like after these impedences have been removed. Also, this angle shows another angle of the port work.
The intercooler cores are installed after the manifold is modified for better airflow, and to accomodate the end tanks where the water goes in and out of the cooler.
After the intercooler cores are installed, a new plenum roof is fabricated to raise the plenum volume and allow additional airflow with less restriction.
This is the finished product. As you can see, the stock holes that allow access to the allen bolts which hold the blower in place, are modified so they no longer protrude in to the plenum area. They are then plugged with brass fittings which do not protrude in to the plenum, and have heads which will prevent threading them too far in to the manifold.
The end tanks are installed with A/N style fittings where the cooling lines connect. These lines pass fluid through the intercooler by way of a pump/heat exchanger (available through LHT), or a pump/water (ice) resevoir setup.
