[LPI]

All of us at LPI are pleased to announce a new chapter in the pursuit of better oiling systems for our beloved Pontiacs.

After extensive R&D we are now offering our increased inlet capacity oil pump with bolt on conical shaped pickup screens. The bolt on pickup screen can be tailored to most any pan depth, stock to race depths.

The new pump features O-ring seals from the block mounting flange to pick-up flange to minimize any type of leakage which can contribute to cavitation.

We will be introducing our new thrust plate with integral pressurized oiling mods for the bottom of the pump gears. This plate is made out of a new material used exclusively in hydraulic pump industry.

The plate is available as a separate item also. Price is $51.00

We have incorporated our new linear piloted pressure relief ball and spring assembly to minimize cracking and erratic movement typically found in the stock arrangement.

The main improvement comes in the area of increased inlet size and capacity.

We have increased the inlet tube size and redesigned the actual pickup screen to be a cone for better inlet flow with less turbulence.

These changes have produced approximately a 90% increase in area over the performance ¾” inlet pickups currently being used.

Why is this important? As the rpm of the engine goes up so does the rpm of the pump. The current design moves into a cavitation state around 5000 engine rpm due to the lack of flow volume to the pump gears. As the engine rpm increases the pump has to work harder and the output demand surpasses the supply and causes even more cavitation.

Another contributing factor in the oiling system is the necessity of windage plates in the oil pan.

With today’s large stroke crankshaft motors there is more windage in the oil pan area and this must be addressed to prevent the windage from uncovering the oil pump pickup at increased rpm levels.

Please give us a call and we can discuss your needs to modify your existing pan or package a pan and pump assembly for your new engine project.
