24 VDC ELECTRIC VACUUM PUMP

The Star Machine Electric Vacuum Pump (EVP) is representative of our continued efforts to provide racers with the latest vacuum pump technology. The EVP is a DC electric, reciprocating piston vacuum pump. It incorporates two dynamic seal pistons, coupled to a common yoke that is eccentrically driven in a common bore. The EVP offers the distinct advantage of ALL the HP gains, thru increased crank case vacuum, with ZERO HP lost to driving a mechanical vacuum pump.

Originally designed for Pro Stock Motorcycle to comply with the one pump rule it is also currently used in Pro Stock Car as a vacuum assist pump. In PSB applications it is equal to 5 times the capacity of the most commonly used pump to produce crank case vacuum. In PSB it is producing vacuum levels of 25 inches Hg.(wire to wire). In PS Car applications it has shown a 15 - 20 percent increase over existing crank case vacuum readings.

At Star Machine we realize that you do not get something for nothing. The electric motor driven EVP 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 is sold (complete) with two 24 VDC (DEWALT Power Tool) rechargeable batteries, 24V Charger, quick change (battery) holder, wiring harness and vacuum hose. The EVP operates (completely) separate from your existing (12/16 VDC) electrical system. To complete the EVP installation one 12V-40A normally open switch is also supplied to operate the pump. (We recommend switching the positive side) The pump is normally supplied with -12 A/N fittings manufactured from 7075. Call for optional fitting possibilities.

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 motors will receive the maximum available battery power.

The vacuum line connection to the engine is critical to the operation of the EVP. Drawing oil into the EVP may result in damage to the reeds. 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. If required, a regulator (STR.04.12.000) can be added directly to the pump.
