CRANK BREATHER TANK 944 8v / 944T

Another first from Lindsey Racing for the 944 8 valve engines. A remote bolt on crank case breather kit for stock machines to race cars.

And when it comes to breathers, BIGGER IS BETTER!!!. Our full 1" tank inlet and supply hose are BIG!. The ideas is the slow down the air so the oil can separate from it. Small hoses and fittings speed up the air and putting on a tank like that is useless.

Venting your crank case back into the engine is great for emissions, but not for optimum performance. All serious race cars have separate catch cans for oil vapor. Why?

1) Oil vapor does not burn. When your engine is pumping or inhaling oil vapor, it is displacing a certain percentage of air/fuel mixture. The more blow-by you have, the more air/fuel you're displacing. This means you're not getting 100% air/fuel into the cylinders. Removing the crank case breather from the intake system will eliminate this problem.

2) Oil vapor reduces the octane rating of your fuel. Oil vapor causes problems in a naturally aspirated engine, but is twice as bad on a turbo charged one, where octane rating is critical. If you're running 93 octane pump gas and injecting oil/air vapor into your combustion chamber, along with your fuel, then you no longer have 93 octane fuel. How much is not certain, but it may mean the difference between detonation and no detonation. Better safe then sorry.

3) When you suck all that oil into your turbo, and into your engine, you can clog your cat, coke up the turbo, and even knock the ring lands out of your pistons as it did on the turbo Mustang and Pontiac.

Does this mean that a remote crank case breather can make HP? Does this mean that a remote crank case breather can help keep from blowing a head gasket? The answer to both questions is "YES"!

We studied the engine compartment for a good installation location. There is not much room anywhere when you have all the stock systems such as cruise control, washer fluid tank and all the other goodies Porsche packed under the hood. We also wanted to make the hose a short run to the connection at the oil separator. We felt the best location is where you see it. It interferes with nothing and makes for a very clean appearance for those who like a tidy engine compartment along with function.

This complete kit comes with everything you need to get the job done. Our 10" overall height aluminum catch tank with K&N filter. The filter has a chrome shield over it allowing you to direct the discharge. A mounting bracket is attached to the tank and bolts to the cam tower. This tank is custom designed and manufactured for us by Stef's, the leader in performance oiling systems, and not an off the shelf part you can purchase anywhere but here. The inlet on the tank is 1" tubing entering the tank at 25 degrees downward, then has a mandril bend, and continues downward inside the tank to a determined length. The smallest portion of this system is the hole in the oil separator it connects to. Many other so called catch tanks run much smaller hose. A smaller hose speeds up the air and can make a mess. When you use a large hose, the air slows down while the volume goes up and it does a much better job of venting without making a mess.

Since the tank is located near the exhaust (which can get hot), we have moved the drain to the bottom of the car so you do not drain oil on to your hot engine. We extend down with an aluminum line to a chrome ball valve attaching to the undercarriage of the car. You can place a container under the drain and collect the oil. You can measure the amount collected and determine the wear and tear on your engine if you like. A car with worn rings will have more blow-by than a car with fresh rings. The custom breather tank is connected to the engine by 3/4" Purosil silicone hose (blue).
