Detailed Product Information
SPORTSMAN EVP MANUAL Performance Graph
The Star Machine Sportsman Electric Vacuum Pump (EVPS) is representative of our continued efforts to provide racers with the latest vacuum pump technology. The EVPS is a DC electric, reciprocating piston vacuum pump. The EVPS offers the distinct advantage of ALL the HP gains, thru increased crank case vacuum, with ZERO HP lost to driving a mechanical vacuum pump. The pump is designed for intermittent (drag race) small displacement engines, less than 120CI. Or, if used with a dry sump oiling system, will add additional vacuum (2 to 4 in. Hg.)

At Star Machine we realize that you don’t get something for nothing. The electric motor
driven EVPS adds the requirement of between round battery maintenance (recharging). This will be
considered, by some racers as a burden (one more between round headache). Other racers, looking for that last .01 second advantage, will view the additional maintenance as part of the game.

The EVP operates off your existing 12 to 30 VDC electrical system. To complete the EVP
installation one 12V-75A normally open switch is required to operate the pump. We recommend switching the positive side. If you would like to control the EVP with a relay we recommend the Bosch 24VDC/50A, PN 0.332.002.250.

The use of other battery systems is OK, as long as the voltage is not exceeding 30VDC.

Activating the pump is presently (and recommended) done when the vehicle is pre-staged.
In most cases at the same time the data recorder is switched on. This will guarantee the pump motor will receive the maximum available battery power.

The vacuum line connection to the engine is critical to the operation of the EVP. Care must be taken to baffle and/or separate the engine oil from the air drawn by the pump. More important to the performance of the pump is the sealing of the engine, the better the seal the higher the potential vacuum. Use clear 5/8” ID vacuum rated hose for the intake and exhaust connections.
