Turbo Boost Leak Testers, Inc. is dedicated to specializing in boost leak testers. That's it!
Test your 2015+ WRX FA20 for leaks the correct way, eliminate any doubts about boost leaks 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 some boost leaks. This throws off the tune, causes air fuel ratios to always be "chasing" for the loss in expected air, messes with ignition timing from increased air temps and reduces fuel economy.
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
The boost leak tester will fit over the stock inlet assembly. This is the block that bolts to the turbo compressor housing. Included in the kit are the diverter valve return plug and 2 of the air return line caps. Using these will be required to properly fill the system with compressed air. Otherwise the compressed air will travel into the crankcase through the vent lines and pressurize the crankcase. With that said remove the oil cap! to keep your crankcase pressure to 0 when filling the system.
Design Features & What's Included:
Lifetime warranty on every component.
Instructions:
1. Lift the vehicle and remove the under-body shield. Remove the turbo intake pipe and expose the inlet block that is bolted to the turbo compressor housing.
2. Install the boost leak tester onto the stock turbo adapter that is bolted to the compressor housing
3. **remove the oil cap to relieve pressure from crankcase
4. Disconnect the diverter valve return line and install 1" plug. Remove the 2 vent return lines and cap them off with provided caps.
5. 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.
6. Increase to 10 pounds, 15 pounds.
7. Now go drive with confidence that the turbo is making full boost safely and efficiently!
