Description

VTT S58 / B58TU Crankcase Vacuum Pump Kit

If you’re building a serious S58, or B58TU, crankcase pressure is one of the biggest hidden enemies of engine performance.

Excess crankcase pressure reduces ring seal, increases blow-by, contaminates engine oil, and costs horsepower. The goal of any properly designed vacuum pump system is to maintain consistent crankcase (pan) vacuum throughout the RPM range, allowing the engine to operate more efficiently under high boost and extreme engine speeds.

Maintaining crankcase vacuum provides several key advantages:

• Increased horsepower throughout the RPM range
• Improved ring seal
• Reduced blow-by
• Reduced oil contamination
• Improved engine efficiency
• Increased reliability in high-boost, high-RPM applications

For maximum performance, engine builders can also utilize low-tension piston rings designed specifically for vacuum pump applications, further improving ring seal while reducing frictional losses.

Catch Can Requirement

A properly sized catch can is REQUIRED when running a vacuum pump.

The catch can must have sufficient internal volume and venting capacity to support the airflow created by the vacuum pump. An undersized catch can will restrict airflow and reduce the effectiveness of the system.

For this reason, we strongly recommend pairing this kit with the VTT High Flow -16 Catch Can, designed specifically for high-flow crankcase evacuation systems. We DO NOT RECOMMEND running a catch can that has LESS than a -12 port; this speeds up the gases, increases oil pickup, and -10 is simply not enough venting for high-powered X58 builds

Kit Overview

The VTT Vacuum Pump Kit is a true plug-and-play solution that bolts directly onto the engine using precision-machined VTT billet brackets and proven GZ Motorsports components.

Designed for dedicated competition vehicles, the system delivers consistent, adjustable crankcase vacuum for improved engine performance, efficiency, and reliability.

Kit Includes

• (Optional) GZ Motorsports Sportsman 104 Vacuum Pump
• (Optional) Pre-installed ½” NPT to -12AN male fittings
• (3) VTT billet mounting brackets
• (Optional) VTT billet vacuum pump pulley
• Serpentine belt
• VTT S58/B58TU -16 oil cap adapter
• -16 ORB to -12AN adapter fitting with 1/8″ NPT port
• Complete mounting hardware

Plumbing Information

The GZ Sportsman 104 utilizes ½” NPT ports and is designed around -12AN plumbing.

• We recommend -12AN hose and fittings for most applications.
• The system can also be adapted to -16AN, and we have successfully tested both configurations.
• Because plumbing varies significantly between vehicles, hoses and fittings are sold separately.

Optional Equipment

Complete your system with:

• VTT High Flow -16 Catch Can Highly Recommended
• VTT Crankcase Pressure Sensor Highly Recommended for monitoring crankcase vacuum and dialing in your vacuum level
• -12AN Braided Hose
• Additional -12AN fittings for your specific plumbing layout

Who Is This Kit For?

This kit is designed for serious performance builds, including:

• Dedicated drag racing vehicles
• Roll racing builds
• Half-mile and standing mile cars
• Road race applications
• X58 engine conversions
• High-horsepower S58 and B58TU competition vehicles

If you’re chasing every last horsepower while improving engine efficiency and reliability, crankcase vacuum is one of the most effective upgrades you can make.

IMPORTANT – PLEASE READ BEFORE ORDERING

THIS KIT REQUIRES REMOVAL OF THE FACTORY AIR CONDITIONING SYSTEM.

The vacuum pump occupies the factory A/C compressor location.

If you do NOT want to delete your air conditioning, DO NOT PURCHASE THIS KIT.

This kit is intended for dedicated competition and race vehicles where maximum engine performance takes priority over retaining the factory A/C system.

The VTT S58 / B58TU Crankcase Vacuum Pump Kit is engineered for racers who understand that controlling crankcase pressure is one of the final steps in maximizing horsepower, ring seal, and long-term engine reliability.
