The S-MAX can features dual inlets and the vapor breathers through the supplied Green filter on top. The catch can has the PCV breather hoses plumbed into it instead of into the intake.
The installation of an S-MAX catch can eliminated this The intercooler yielded around half a liter when we tipped it over and the blow-off valves needed to be degreased heavily so they would not leak under boost. The performance of the car was also suffering from the restriction of loads of oil in the system. We know too because it cost us a turbo and lots of clean-up to remedy the situation. Although your car may be able to burn the oil vapor off, we have seen firsthand what all kinds of hard driving can do over time.” “To go fast you want the right mixture of air and fuel,” says Dave Hary, the owner of S-Max. They were both covered in oil and dirt, also a result of the excess oil in the system. The result is that the assembly became off-balance and ended up breaking at 120,000RPM! The oil in the intake system was even worse than we expected when we removed the GReddy intercooler and the twin HKS Sequential blow-off valves. During the tear down, we noticed the turbo with the missing turbine had its compressor side caked in oil. Luckily it was a clean break but we have a theory about why the exhaust wheel snapped clean off and flew out the exhaust. We cleaned it and everything was fine but a few months later, one of the turbos failed at Mosport on the Mario Andretti Straightaway at over 200km/h.
One issue we have had with our project GT-R has to be the oil blow-by in the Positive Crankcase Ventilation (PCV) system, so we wanted to talk with S-Max Performance about their fresh catch can design.Įarlier in the year we even had one of the MAFS covered in oil and grime, which caused the car to buck and hesitate. So be sure to inspect them all and, if possible, add upgrades that will perform better. Even the smallest hydraulic, cooling or lubrication items might become an issue later on down the road. The best approach to modifying your car is a balanced approach to every system. When tuning your car it is easy to overlook the finishing touches.
