Universal & Engine-Specific Kits for LS, SBC & BBC Builds

Every engine layout handles crankcase evacuation differently. Modern forced-induction V8s need consistent suction across the whole rev range, which is why an ls vacuum pump kit is standard gear for high-boost setups. For traditional pushrod platforms, bolt-on SBC vacuum pump kit bracketry and BBC vacuum pump kit options handle the extreme blow-by generated by large-displacement drag motors.

Driving the unit directly off your harmonic balancer with a dedicated vacuum pump drive kit ensures your suction scales smoothly as engine revs amp up. Choosing a belt driven vacuum pump setup gives you precise control over your vacuum levels using interchangeable pulleys. We carry popular options like the Moroso vacuum pump, dedicated oil vacuum pump units, and complete dry sump vacuum pump kit setups for severe-duty motorsport, managing both oil scavenging and crankcase vacuum in one package.

Build a Complete Engine Oiling System with VPW

Pulling negative crankcase pressure works best when the rest of your oiling system is built to match. Controlling fluid slosh with internal baffles in our oil pans keeps oil down in the sump where it belongs, preventing the pump from sucking up liquid fluid mist.

While you’re at it, you can pair your evacuation setup with our high-volume oil pumps to maintain rock-solid oil pressure across your bearings. You can also run your lines through high-efficiency oil coolers to control fluid breakdown on hot track days, and trap fine debris using high-flow oil filters. As Australia's leading destination for performance car parts, VPW supplies the gear you need to protect your engine build.

Frequently Asked Questions

What does a vacuum pump do on a racing engine?

An engine vacuum pump pulls air out of the crankcase to eliminate pressure build-up caused by piston blow-by. Creating negative pressure inside the block stops piston ring flutter, improves ring seal against cylinder walls, reduces windage drag on the crankshaft, and prevents oil from blowing past engine seals.

Do I need a vacuum pump for a street or daily driven engine?

You don’t usually need a vacuum pump for a street or daily-driven engine, as they produce minimal blow-by, so a standard PCV valve or a catch can setup handles crankcase pressure fine. You only need a dedicated vacuum pump once you're running high boost, massive compression, or spinning a race engine high enough to overwhelm standard breathers.

What's the difference between a dry sump and wet sump vacuum pump setup?

On a wet sump engine, oil stays in the pan, so you mount a separate vacuum pump to pull air out of the rocker covers. A dry sump kit, on the other hand, is a multi-stage scavenge pump pulls both oil and air straight out of the pan together, creating a natural crankcase vacuum without needing a standalone pump.

How do I install a belt-driven vacuum pump kit?

Bolt the mounting bracket to the cylinder head or engine block and lock the drive mandrel onto your crank pulley. Align your belt, run a reinforced hose from a baffled valve cover fitting to the pump inlet, and route the discharge line into a vented catch tank. Finally, fit an adjustable vacuum relief valve to regulate your suction levels. If you need help, don’t be shy to ask a professional!

What size of CFM vacuum pump do I need for my engine?

The CFM vacuum pump size you should get depends on engine displacement, boost levels, and max RPM. For some context, a standard 3-vane pump (pulling around 10 to 12 CFM) handles most small blocks spinning under 7,000 RPM. Large-displacement big blocks, high-RPM race motors, or blown setups need a 4-vane pump pulling 15+ CFM to clear the extra blow-by volume.

Can I run a vacuum pump with a stock oil pan?

Yes, you can run a vacuum pump with a stock oil pan as long as the engine is completely sealed and you use an adjustable vacuum relief valve. However, stock oil pans lack windage trays and baffles, so pulling high vacuum without a regulator can pull oil mist out of the sump or starve wrist pins of splash lubrication.
