-------------------------------
Bosch "044" Motorsport fuel pump is our most popular high performance fuel pump. With reliability that the big German company is known for, it's our #1 choice in our workshop here. For upto 730HP at the flywheel or use two pumps for upto 1200HP on turbocharged applications.
As performance levels increase via greater airflow efficiency or higher boost levels, fuel delivery is crucial in developing maximum horsepower and in maintaining proper air/fuel ratios.
The Bosch In-line Fuel Pump upgrade replaces the factory pump to maximize flow for high boost applications where the factory injector pulse duration is substantially increased or where additional or larger injectors are utilized.
