Howie, I honestly thought you had ordered one a short while ago. If we can round up another 10 people who want them, I'll order again. Lead time for the aluminum cans is about 2 weeks. The filter (with zinc can) takes about 1 week to get here. Since there is an additional price break at 10 pieces, I am throwing in the brass tube fittings and thumb screws to mount the filter to the bracket. The only things the end user will need are sheet metal screws (if mounting to the front cross beam), fuel line, and hose clamps.

count me in

 

Don't sweat it Dave.....I am just bustin your chops.

Have the other guys installed and tested?? Any locals??

I'm going to check out Charlies can but please don't forget me again


DH

 

I would by one as well. Let me know if this happens please.

 

That's okay, Howie; I'm used to it! I haven't received the first batch yet, but I will inquire as to whether I can have the machine shop vendor make a few more before the original 10 are shipped. I can't promise anything, but at least I can try. My filter is doing an excellent job of trapping aerosols.
It looks like you, Kln and PDD are interested, so I will let you guys know if I can get a few more added without incuring extra cost for lower quantities.

If your serious, don't run any PCV system.Just run breathers. We've tested alot of catch cans and they all let oil into the intake.On our 12-1 comp. strret cars just alittle oil can kill them.

The only down side is that you should change the oil every 2k miles after which most people should do anyways if your hard on the car.

And yes,we did test hp differences and how the vacuum from the PCV helps the engine seal ect.On a NA 400-500hp car it made no difference at all.Only thing better is a vacuum pump setup.

 

This is good infor on the HP comparison...thanks!!!

What about oil smell and leakage from the breathers.

If oil needs to be changed every 2K how about running good dyno oil instead of synthetic to keep the cost down??

Very rarely there is an oil smell.On the oil change you clean the breather too.The breathers drip oil because they are loaded with oil.If they are kept clean they don't leak. Another trick is to run the PCV lines to a catch tank with a breather.
As for oil changes I haven't heard any complaints.Of course these setups are on motor with $8k -$40k into them so $50 every 2k miles isn't much for maintanence cost.

 

Speaking in manufacturing industry terms, there are many "downstream" (of compressors) machines and instruments that cannot tolerate any oil as well. The solution is two or three-fold. First, a particulate filter is used to trap bulk liquids (mostly water that has condensed in the air line between the compressor and the filter) and course debris. In our case, this is not really necessary unless, perhaps, there is a ring-sealing problem and more-than-there-should-be oil is flowing past the PCV valve.
Secondly, the true coalescing filter is assembled in series with the particulate filter. This coalescing filter can trap oil aerosols down to .01 micron. Grade C filter (Wilkerson designation) elements are used when the air has to be "oil-free". Critical air control circuits, air logic systems, flow and temperature controllers, food processing, electronics, health care and film processing are some critical end-use "recipients" of oil-free air. Most of our LS1s would not be included in a list such as this.

Also, if oil odor needs to be removed, there are activated carbon element filters are available, making up the third line of defense for such applications. Obviously, this type of filter is a bit overkill for our requirements.

So yes, there are filters than trap all of the oil on its way to the TB, but for the average C5 owner, only one is likely to be necessary, and as was mentioned previously, a common "catch can" is probably not the best solution - better than having nothing, but not optimal.
