PULL HARDER , IMPROVE MPG & KEEP YOUR MOTOR HEALTHY --BY ELIMINATING BOOST LEAKS!Test your Cummins Turbo Motor for leaks the correct way and keep the motor running healthy and tow with confidence! Many Cummins owners don't even know they have a boost leak until it is diagnosed and fixed then feel the real torque their motor was supposed to be putting out! This easy boost leak test will take 10 minutes and will detect any leaks in any of the charge pipes, cac intercooler, cold side pipes and intake manifold. All common and potential leak points. A boost leak will cause the turbo wheels to over-spin to try and make up for the lost pressure. This puts a lot of strain on the turbo and it will start to develop shaft play from running too fast too hot and poor oiling. Boost leaks can start out small and eventually turn into a blow-out or worse if left alone can eventually cause the turbo to fail. For tuned motors running higher boost the leaks present a much more severe over-spinning to compensate for the leak AND the higher boost from the tune. This accelerates the turbo failure and expensive repairs replacing turbos and other damaged engine components. *If you have replaced a turbo, it could possibly have failed because of a boost leak, so its wise to test for leaks after installing to ensure the system is leak freeIt is common that aftermarket parts are installed and not pressure tested, even by some experienced installers - robbing the additional power they were supposed to make. Avoid costly repairs, especially if tuned, towing or want the peace of mind going full throttle on the pedal every time you hear that turbo spoolin' up!The main signs you have a leak are:Lower fuel economy!CEL / Check engine light / MIL P0299 Loss of power, torque, poor towingWhistling noises, as awesome as they sound!Fluctuations on boost gaugeThis boost leak tester will pressurize the whole charge pipe path and detect any leaks including:all intercooler and charge pipesCAC / intercoolerevery single clamped connectiono-ring connectionsEGR leaksintake manifold ...basically everything the turbo normally pressurizes while under boost. Compatible with the following applications:Cummins ISB 5.9L I-6 in the RAM 2500 and 3500 up to 2007Both stock and aftermarket bolt in turbos using the same size intake plumbing_________________________________________________________________________________ How to Order:The Cummins boost leak tester kit is offered in 2 variations:These sizes will work with stock turbos and aftermarket upgrades as well that use the same intake piping sizes[Choose your Kit Type] Premium Kit: Billet Aluminum Boost Leak Tester Kit, 3" End cap adaptable to many other sizes, Threaded M-Type Air fittings 1/4" NPT, 30 PSI gauge Premium Kit w/Extension: Adds the 5ft Extension hose with ball valve, M-Type Air fittings 1/4" NPT, with quick connects *highly recommended to include the Extension Line Kit since it will allow you to test and fill air without leaning over the bay. Also has the convenient ball valve to easily regulate pressureIf you have a huge aftermarket turbo, ex 5" or larger, check out _________________________________________________________________________________ How to use this tester:This tester installs right on the turbo inlet flange. This is the most ideal location as its the beginning of the charge pipe path and pressurizes the whole sysem. 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 an 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 in-audible 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.
