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 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 downward. 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).

We also offer our "Universal" breather tank kit for the 944s. Universal in the sense that it comes with a 3" saddle clamp allowing you to bolt it to a location of your choice rather than attaching to the cam tower. This is more suited for a race car where you have plenty of space under the hood and don't have systems like cruise control, lights and AC getting in the way. The universal kit comes with 3' of silicone hose allowing installation almost anywhere.

We recommend the removal of the intake manifold to install the system (good time to buy a Lindsey Racing Intake Manifold). You will be running the vent out the back and no longer need the steel line attached to the intake and running forward to the air intake. This will clean up your engine's looks.

This is also a good time to change your aging vacuum lines with our 951 Vacuum Line Kit.

This system is actually overbuilt for the 944 as it is. The oil separator has a nipple on the top in which our breather tank connects to. Inside this nipple the factory has a small hole only measuring .240" in diameter. You can enlarge the hole to .540" which is the inside diameter of the nipple and gain 500% in the volume of air that can pass through the orifice into the breather tank, fully utilizing the capability of our breather tank system. We recommend you remove the oil separator and drill or enlarge the hole while holding the tank up-side down so shavings will not be lost in the tank. The oil separator is hollow and can be flushed out if needed.

You can do that modification next time you have your turbo off.

We have no way to know for sure why Porsche made the orifice so small. We suspect that if it was larger, the vacuum created from the turbo inlet, where the factory connects it, may suck too much oil from the oil separator, so they restricted it. We recommend you only enlarge this hole in the separator when running to a separate catch-can system such as ours, otherwise, you can increase the problems with air/fuel displacement and diminished octane problems.

The oil separator has two o-rings that seal it to the block. These o-rings get dry and brittle over time and leak oil out the side of the block. It is wise to change these out while removing your oil separator. Removal of the intake manifold is necessary to remove the oil separator.



FULL 1" AOS NIPPLE KIT

For optimal scavenging of the crank case air, we offer our 1" Air Oil Separator Nipple upgrade. This makes for a full 1" hose from the Lindsey Racing Breather Tank to the AOS tank. The stock AOS fitting is much smaller.



You can purchase this as a upgrade after the fact if you didn't order it when you originally ordered your tank, or select that option when ordering your kit today.



NOTE: This is for Breather Tanks with the 1" nipple from the tank, not the original 3/4" nipple.

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.

A good bit of our business is International and we have been taking care of those valued customers since 1999.
