3.25" Universal Turbo Boost Leak Tester Kit - Billet Aluminum - 30 PSI Gauge - Find P0299 Boost Leaks

Get your boost back!  

This boost leak tester is designed to fit over the inlet flange of your turbocharger and allows you to pressurize the turbo and charge system with compressed air while the vehicle is off. 

This is an important tool that every turbo car owner needs in their arsenal of tools.  It is going to keep the turbo healthy by eliminating leaks in the boost path and not allowing it to overspeed compensating for a boost leak.   It is a must if you are tuned and/or going to get a custom tune, or any time you are replacing any components in the intake tract such as charge hoses, intercooler, manifold, vacuum lines, injectors…etc.  Also a must if you are going to the track and want the peace of mind that everything is tight and capable of handling sustained boost without blowing any hoses off

Why the boost gauge matters

Not having a gauge readout on a boost leak test is similar to filling air in your car's tire without a gauge.  You just don't know how much air is in the system!   

It is very wise to know how much pressure is actually going into the charge system to prevent damage to your engine and to yourself - Example if the compressor is unregulated (using high pressure shop air at 90 PSI) there is a risk that the charge pipes will be over-pressurized and something will give - the boost leak tester could blow off or any component of the engine could.   

The gauge on the boost leak tester allows the user to:

1. apply a safe amount of pressure to prevent injury or damage to the charge pipes or engine
2. read how fast the system holds and bleeds air after removing the air source
3. 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:

• Billet 6061 Aluminum End Cap 3" OD with 1/8" NPT threaded gauge port & fitting port
• High quality silicone coupler 3" height
• Custom Stainless Steel 30 PSI / 2 Bar Boost Gauge
• 30 PSI range will give you the appropriate reading when testing your charge pipes for low, medium or high boost levels.
• Universal Tire Schrader Valve OR Compressor fitting with purchase of extension hose kit
• (2) Stainless Steel T-bolt Clamps with Teflon lock-nut

Option to add an Extension Hose Kit:  
Will allow control over shop air and manage the pressure entering into your turbo system.   Mandatory for shop environment where the air compressor is inaccessible.  The ball valve lets you turn on and off the pressure into the system - this can be very important for you to check the decay or bleed rate after filling the system with pressure.   The bleed rate lets you know how well the system holds and this can only be done by cutting off the pressure to the tester with the shut-off valve.
