The Walbro 450 LPH "turbine style" in-tank High Pressure fuel pump is a brand new aftermarket release for 2011. Designed to meet the fuel-hungry demands of modern turbocharging enthusiasts the Walbro 400lph High Pressure unit can flow close to the amount as dual intank pumps or large externals but in a small, convenient and surprisingly quiet package. This pump is a great solution for high fuel requirement turbocharged cars >500hp and anyone looking to make big power and run high boost with a simple fuel system where the 255 won't suffice. This much fuel flow is not meant for use on engines <400hp.

Walbro's turbine pump head uses two sets of turbine blades set in parallel on a common shaft (like a jet engine). This high efficiency pump design pressurizes the fuel as it flows through the pump axially without forcing the fluid to change direction - the end result is tremendous flow rates at a variety of different rail pressures and to suit various injector sizes:
