How? Here's what the folks at Lindsey Racing have to say:
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"!
Let me hazard a guess here, Lindsey Racing is selling oil catch can kits?
The amount of oil that enters a cylinder on a car without the CC kit is minute, you only have to see the amount of oil collected in the can when you change the oil. Divide that amount of oil by the number of firing strokes of that engine in that time to realize it. That 5-7 hp that must be on a real loose engine burning oil by the bucket.
The CC kit they are selling is totally different from the one we use, our system is closed and opening it up like theirs would wreck the tune.
