from

$76.99
The updated Fuel Pump Booster is an easy way to maintain the proper fuel pressure on your car after adding a power adder such as a turbo or supercharger. The new model allows you to make your boost adjustments through a PC for improved control and accuracy. The Booster ensures that the engine receives the fuel it needs to make up for the increase in air being pumped into the intake manifold. It will increase the voltage to the factory fuel pump in proportion to manifold boost pressure in order to maintain the proper fuel delivery. The amount of increase is adjustable from a range of an additional 1.5 -22 volts up to 30 psi which can all be set and adjusted from your PC with MSD’s easy to use Windows based software. The MSD Booster will wire to the factory fuel pump relay or with a secondary booster pump.

Product Features:
  • Direct performance replacement
  • For GM 2 Tower Coils Used From Mid 1980s To Late 1990s

Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Furnace brazed impeller. New precision steel alloy pump drive tube. New heavy duty needle bearing between stator and impeller (not a thrust washer). Needle bearing between stator and turbine. Furnace brazed turbine.
