Test your BMW single turbo N55 motor the easy way!
This Boost Leak Tester kit mounts the inlet pipe of your turbo that lead to your turbo's compressor inlet flanges. The turbo intake hose that wraps around the top/back of the motor is removed and the turbo inlet flange is exposed which is where you will install the boost leak tester. You'll be able to test from the turbo to the motor checking all leak points in between, including intercooler, clamped connections, throttle body o-ring, intake manifold, divertor valves and the many random potential leak points.
Note* the turbo inlet flange where you will clamp the boost leak tester on is plastic and take caution not to over-clamp the boost leak tester on this flange. That being said, use low pressure to start testing the system and work your way up to 15 psi.
Comes standard with a 30-PSI gauge, threaded tire valve stem fitting and (2) stainless steel T-bolt clamps.
The top-mounted threaded boost gauge to easily read the pressure in the system while testing without having to run into the driver's seat to read the boost.
