Turbo Boost Leak Testers, Inc. is dedicated to specializing in boost leak testers. That's it!
Test your WRX FA20 for leaks the correct way and keep the motor running healthy and boost with confidence!
Pressurizing the system will allow you to run peak boost your motor was tuned for and ensure you are putting all the power down without any leaks. A boost leak will cause the compressor wheels to over-spin to compensate for the lost pressure. Eventually this puts a lot of strain on the turbos and they start to develop shaft play from running hot and poor oiling. It's an inevitable test that every turbo motor owner should eventually do to keep the motor in good health and avoid costly repairs, especially if tuned, street racing or any track racing. Too many times we've seen customer cars come in thinking there aren't any boost leaks or "it's been smoke tested" only to find a few leaks. This throws off the tune, causes air fuel ratios to always be "chasing" for the loss in expected air.
This boost leak tester will pressurize the whole charge pipe path and detect any leaks from the turbo to the motor. This includes faulty diverter/BOVs, clamped connections in the charge pipe, intercooler and all connections at the intake manifold. Basically everything the turbo normally pressurizes
Designed for the Perrin 3" intake. The boost leak tester will fit over the 3" Perrin adapter plate that bolts to the turbo compressor housing. Doing the boost leak test at this point will eliminate the need to block off the diverter valve return line, PCV return and other miscellaneous lines connected to the intake pipe before the turbo.
This boost leak tester will fit with the Perrin intake with the link below. Or with any other intake pipe you are running that is 3" in diameter.
*If you are only running the Perrin Cold Air Intake Pipe and not the turbo inlet pipe use our WRX FA20 stock intake pipe tester instead.
Design Features & What's Included:
Lifetime warranty on every component.
Instructions:
1. Lift the vehicle and remove the underbody shield. Remove the turbo intake pipe
2. Install the boost leak tester onto the Perrin 3" turbo adapter that is bolted to the compressor housing
3. **remove the oil cap to relieve pressure from crankcase
4. Fill the system with a compressor. Start with low pressure such as 5 PSI. Listen for leaks, fix leaks and repeat to catch the next leak. Largest leaks are found first.
5. Increase to 10 pounds, 15 pounds.
6. Now go drive with confidence that the turbo is making full boost safely and efficiently!
