This Boost Leak Tester kit mounts inside both of the flexible intake hoses that lead to your turbo's compressor inlet flanges. You will need to remove the air box (or your aftermarket air filters) to expose the 2 intake pipes. Install the testers in each pipe and pressurize the system using the tire schrader with your tire inflation tool. The kit comes with the necessary caps to block the diverter valve return flanges on the intake pipes, also a cap to block the breather line at the bakc of the valve cover. Once the kit is installed, use compressed air to charge the system and you will see that both gauges read the compressor pressure you are filling with. You'll be able to test the turbo to the motor checking all leak points in between, including intercooler, clamped connections, intake manifold, divertor valves and the many random potential leak points. Note: Testing at the intake pipe, you may hear noise coming from the o-ring (at ~12 psi test pressure) that seals the intake pipe to the turbo inlet from debris. This is not a boost leak, these are not meant to see boost and not intended to be perfectly sealed, however hearing this hissing may be mis-diagnosed as a leak. In this case reduce the pressure. If no obvious leaks are heard in any other location, the test is complete and there are no significant leaks The gauge on the boost leak tester allows the user to: apply a safe amount of pressure to prevent injury or damage to the charge pipes or engine read how fast the system holds and bleeds air after removing the air source give a good comparison of compressor outlet air Vs. boost test air while pressurizing. The smaller the difference the lesser the air loss in the system Design Features: Plastic End Caps with 1/8" NPT threaded gauge port & fitting port Boost Gauges with 30 PSI / 1Bar Boost Gauge Universal Tire Schrader Valve (can be removed and tapped for 1/4" NPT thread fitting if desired) (2) Stainless Steel T-Bolt Clamps with Teflon lock-nut (3) Vinyl Caps for diverter valve return and valve cover breather

Vargas turbochargers feature a complete redesign of key components, including the compressor housing, bearing housing, and turbine housing. These turbos are specifically engineered to fit in the stock N54 location while offering the flow capacity of much larger units. Every detail has been carefully designed to meet our performance, flow, and reliability objectives. The result is a turbo that fits the stock location and supports up to 700WHP. To achieve this, the internal areas of the manifolds, turbine, and compressor housings have been expanded. Additionally, the AR ratio of the turbine housing has been slightly increased to enhance flow without compromising spool time. Simply put, no other turbocharger—whether single or twin—can match the spool, ease of fitment, power, or reliability of our “GC LITE” turbos, which are capable of delivering 700WHP.
