Honda 3" & 4" Boost Leak Tester Combo - Medium Frame Turbo Builds - Billet Aluminum 30 PSI

GET YOUR BOOST BACK!

Test your Honda turbo setup at the turbo inlet and find leaks fast. Most builds are losing power and don’t even know it. It just doesn't feel as fast as it used to — fix the leak and feel the boost hit like it should. 

Find Leaks in Minutes

Checks your entire system with your engine off:

• Charge piping
• Intercooler
• Couplers & clamps
• Intake manifold
• sensor bungs
• injector seals 
•  throttle body and gaskets
•  blow off valve
•  wastegate
• vacuum lines & PCV

All the common leak points on boosted Honda builds.

Smoke testing is not sufficient as it only tests low pressure 1 PSI.

Why It Matters

Boost leaks =

• Weak pull
• Slow spool
• Lost MPG
• Turbo working overtime

Left alone → blown couplers, shaft play, or worse… turbo failure.

Test it. Most failures start with a leak.

Add an extension line kit to make the testing easier, less reaching and allows fine control for consistent pressure management, making it an easy one-man test. 

Fitment

Fits 3"–4" turbo inlet / intake piping
Installs directly on your turbo inlet

Common Honda setups:

• K-Series turbo builds
• K-swapped Civics / Integras
• B-Series turbo
• D-Series turbo
• Small frame setups

Be sure to measure your turbo inlet for correct size.

How to use this tester:

This tester installs right on the turbo inlet flange.  This is the most ideal location as it's the beginning of the charge pipe path and pressurizes the whole system. Secure the boost leak tester with the provided T-bolt clamps and start your test with a lower pressure on your compressor and listen for leaks. The larger the compressor the more filling time you have between it switching on for refill. 

Tips using the tester with a Schrader valve kit:  Work your way up to 10 PSI, 20 PSI and watch the bleed down rate of the pressure on the gauge.  30 PSI should be sufficient for any turbo system.  Bleed down rate can be used as a check instead of filling the system with pressures over 30 PSI. 1 PSI/second is a general rule. Bleed down is faster at higher pressure and slows at lower pressure.

Tips using the kit with a compressor fitting: Absolutely need to regulate the compressor pressure down or there is a risk of over pressurizing the system!  This can lead to a violent blow-off of the tester cap or a charge pipe connection. It is highly recommended to use the Line Extension kit with the ball valve for pressure control. Regulate down the pressure to 0 PSI. Connect the regulator kit and allow 5 PSI of pressure to fill the system. Listen for leaks. Work your way up to 20 PSI.   

Fix all leaks that are audible and use a soapy spray to find smaller inaudible leaks.   After all leaks are fixed, test one last time, shut the control valve off and trap the air in the charge pipes to watch how the system bleeds the air.   Slower the better.  Normal is about 1 PSI/s at higher pressure and as it drops below 10 PSI the system should bleed down slower.
