When you start making big power you will inevitably have blow by which will result in crankcase pressure. Eliminating the crankcase pressure will make more power and also be much better for your turbo since the oil will return better (non pressurized oil does not like to drain into a pressurized oil pan). Our catch cans are designed to bolt in the factory battery tray in an EG/EK/DC chassis and come with 6 –10 male bungs and 3 filters. We generally run 2 –10 lines from the front of the valve cover, 2 –10 lines from the rear of the valve cover, and 2 –10 lines from the oil drain back plugs in the rear of the block. These block plugs also double as drain backs from the catch can when there is no crankcase pressure. There’s enough capacity and volume to get crankcase pressure back down to 0, even in 800+hp applications. The extra volume ensures no more oil spills from the catch can overflowing like the traditional catch can setups on the market. After a year of fighting with oil spills from our Moroso catch can in our race car, we decided to solve the problem by building these.
Technical Specification
We generally run 2 -10 lines from the front of the valve cover, 2 -10 lines from the rear of the valve cover, and 2 -10 lines to the block plugs in the rear of the block. This results in 6 -10 lines breathing when there is crank case pressure, and the 2 lines going to the block double as drain backs when there is no crankcase pressure.
