The High Flow Fan Shroud has provided us with more room between the backside of the Shroud and the Firewall inside the engine compartment.
We purchase the Aluminum Air Bonnets from CB Performance and modify them to fit the High Flow Shroud. We fabricated a proto type air filter and send it to Uni Filters in Fullerton, CA.
These TWO LAYER FOAM Filters are a ONE Piece construction, reinforced with an internal wire mesh and two inch mounting flanges. Two Hose Clamps secure the Filter to the Air Bonnets.
The Air Filters are 18” long and 5” in diameter. For EXTRA LONG Stroker Engines, we have 19 ½” long Filters.
The Aluminum Air Bonnets, used in this application, cut 70% of the roaring Carburetor NOISE and delivering THREE Times more Unrestricted Air Flow. These improvements resulted in extremely accurate Air-Fuel Mixture Control.
We DYNO tested a 1915cc engine, Hydraulic lifters and dual 40mm HPMX Carburetors from EMPI.
120 Mains- 200 Air – 52 Idle Jets – F-11 Emulsion Tubes, running the engine under load up to 5500 RPM,
the engine maintained a near Perfect Air-Fuel Ratio 14.4:1 to 14.6:1 (Perfect Ratio is 14.7:1)
This kind of Fuel Mixture Control allows the engine to perform at an optimum and at the same time delivers excellent Gas Mileage.
Please note, our HIGH FLOW AIR FILTERS will only fit the HIGH FLOW FAN HOUSING.
