Using this compound turbo system is a great way to boost your Cummins engine's performance. First, gather all the included parts like nuts, bolts, hoses, and the wire loom. Make sure you have the right tools for the job. The average install time is 4 - 8 hours, but it can vary based on your skill. The system doesn't require any welding or major modifications to the engine bay, so it's relatively straightforward. When installing, place the S400 charger in the optimal position as designed, which helps with the routing of all components. The two - piece downpipe with the smooth - flow flange allows for easy adjustment to fit your existing exhaust system. Remember, the atmospheric turbo is sold separately. This system isn't compatible with the factory emission system, and you'll need custom tuning to get the most out of it. For maintenance, regularly check the heavy - duty 4 - ply silicone couplers and stainless t - bolt clamps at every boosted connection. Also, keep an eye on the oil and water lines, which are of premium quality. The intermediate exhaust pipe, coated with 2000F - capable Cerakote, should be inspected for any signs of wear. Clean the Pusher 50 CAL Air Filter periodically to ensure good air intake. Overall, this system is designed to be user - friendly and reliable, giving you improved power, towing ability, and fuel economy.
