Turbo Boost Leak Testers, Inc is dedicated to making boost leak testers – Thats it!
We have been producing testers and optimizing the design since 2007 with a few goals in mind - To keep them cost effective, simple and durable. We also have a new line of Billet Aluminum boost leak testers in every size!
The first thing to do if experiencing issues on turbo motor is check the health of the intake system to see how it can hold to boost. Its is easy to perform this. More times than not there is a leak somewhere in the line which will make the motor respond sluggish, waste fuel and ultimately lead to turbo damage is not taken care of.
Works on ALL VW 1.9L TDI diesel engines:
- All 1.9 R4 8v TDI
- 1.9L TDI engines produced between 1995 - 2007
This boost leak tester will install pre-turbo on the inlet pipe to make testing very easy. Testing pre-turbo only requres capping off the PCV return hose on the inlet pipe with the supplied rubber cap. (see photos) No need to cap the throttle body. This will test the whole turbo charge pipe system including connections, hoses, pipes, intercooler, and most importantly the pesky clamped connections!
Fill the system and find all those leaks that are killing fuel economy and taxing the turbo charger, reducing life and potentially failure.
Installing a new turbo, its strongly recommended to check for leaks possibly avoid the reason the turbo is being swapped in the first place!

Get your boost back and get Full Performance From Your Turbo!
This boost leak tester is designed to fit over the inlet flange of your turbo charger and allows you to pressurize the charge system with compressed air while the vehicle is off.
This is an important tool every turbo car owner needs in their arsenal of tools. It will keep the turbo healthy by eliminating leaks in the boost path and not allowing it to over speed compensating for a boost leak. This will eventually lead to bearing wear and shaft play. Boost leak testing is a must if you are tuned or any time you are replacing any components in the intake tract such as charge hoses, intercooler, manifold, vac lines, injectors…etc. Also a must if you are going to the track and want the peace of mind that the turbo wont over-work or risk blowing any hoses off that are loose!
Importance of the Boost Gauge?
Absolutely necessary for a proper boost leak test! Not having a gauge readout on a boost leak test is like pumping up your car's tire without a pressure read out. You just don't know how much air is in the system!
It’s wise to know how much pressure is actually going into the charge system to prevent damage to the engine and to yourself. For example, if the compressor is unregulated (ex. shop air at 90 PSI) there is a risk that you can over-pressurized and something will give.
Benefits of Gauge:
1. Allows you to apply a safe amount of pressure to prevent injury or damage
2. Read how fast the system holds and bleeds air
3. Gives a good comparison of compressor outlet air Vs. boost test air while pressurizing.
(lower the difference the better)
How do I know if I have a Boost Leak??
Typically the boost target will be lower than what is expected by the tune
Boost onset could be erratic
Slower than normal spool-up
P-codes, Check engine lights – system too rich
What happens to the turbo charger if there is a boost leak??
Any leak will cause the turbo’s wheels to over-spin and result in bearing to wear out eventually causing shaft play! This happens faster with larger leaks. This conditions then allows for the turbo’s wheel tips to make physical contact with the turbo housing. It’s over for your turbo at that point!
Simple Steps to Use the Boost Leak Tester:
1. Remove the outet hose off your turbo chargers outlet pipe (leads to intercooler)
2. Install the boost leak tester onto the turbo chargers outlet pipe and secure with the T-bolt clamps
3. Pressurize the boost leak tester with an air compressor and a tire inflator tool. The air compressor should be a minimum of 2 gallon volume. The larger the compressor, the more capacity you have to fill the engine’s charge pipes. A bike pump or electric pump will not supply enough air fast enough to fill the system
4. *Caution! - When filling the system, start with a low pressure around 5 PSI. Recommended to regulate the compressor to a lower pressure and only increase if filling is too slow.
· The boost gauge reading indicates how much compressed air is in the charge pipes.
· The boost gauge allows you to read the bleed rate of charge pipes when you remove the pressure. It is normal to see pressure loss average of 1psi every second. Faster bleed rate at higher pressures and slower bleed rate at lower pressures
5. Listen for leaks. Use soapy spray if necessary to identify smaller leaks.
6. Fix any leaks points and then retest. Increase by 5 psi up to the normal operating boost pressure.
7. Go out and Boost! Enjoy the restored power from your engine!
Disclaimer: By purchasing this tester you assume all risk when working with compressed air. It is required to use certified safety goggles. Also you need to know that the larger diameter of your turbo inlet, the clamp needs to work exponentially harder. Example if a 2” boost leak tester is clamped down and test pressure is 10 psi, then the clamp force needs to be 31 lbs. A 4” boost leak tester is not double the force, but squared. So the 4” clamp would need to support 125 lbs!! I assume no responsibility to any damage incurred to you or your vehicle from use of this product.
Refunds will be given on unused items and return shipping will be the responsibility of the buyer unless there are warranty issues with the product or the wrong product was shipped.
