Were dealers for most all and install & do these builds weekly. You need to have a flushing flow through the crankcase & you also need a filtered fresh air source for the make up air.

With a supercharged application, we add inline check valves so when at idle or low/no boost the intake is the vacuum source, but when under boost the checkvalves shut off any chance of reversion or the boost pressurizing the crankcase. Then it is the intake side of the blower that provides the vacuum.

The LPE is a typical roots type blower?? I am a little confused.

I wasn't able to contact LPE today.. I was pretty busy doing stuff with the wife. It is on my important 'to do' list...

I don't like to add things to my build unless LPE knows or approves of it first. Especially when it has to do with the engine. They provide a warranty on my engine and s/c and I don't want to add anything, even though it may seem beneficial , without consulting with LPE first.

Yup... I'm with ya Speed. I want to hear or talk to someone at LPE before I do anything with adding the catch can.

LPE uses the Magnuson twin screw roots type blower, a very good piece we have used for years & their kit is first class in every way.

The other two popular twin screws are the Kenne Bell, which although is a pretty decent unit....their customer service is almost non-existant & some of the most arrogant jerks we have dealt with.

And the Whipple which is a great unit & they have great service.

The Maggie is nice with the countershaft design and LPE has put their kit together better than most.

The bottom line is, you do NOT want oil entering the intake either through the head unit or directly into the intake base. Nothing good comes from oil entering the combustion chamber (detonation, less power, carbon buildup, etc.) and you do not want oil buildup on the rotors as clearance is extremely tight & exact and any oil film will cause buildup of any dirt/dust/lint, etc. that may get past the intake air filter and you want NO interferance between the rotors that may result in damage.

All,
There are many reasons why oil is sometimes pushed through the breather system, fundamentally as we design engines to fit within smaller cube sizes we run into issues with the systems ability to allow the oil vapors to drop out of suspension in the air flow. When the LS series of engine was developed back in the early 90’s there were major oil control issues, it’s not the first engine to have these issues and it will not be the last. In order for the oil to separate the velocity of the airflow needs to be at or below 1m/s and as the internal volume of the engine is reduced by package and weight constraints it becomes more difficult to find this “quiet” place where the air velocity slows and the oil can separate. The catch can merely offers more volume and, if correctly designed provides this ”quiet” place. So if oil carry over is an issue the catch can, can be a remedy for this. The crank windage and the effectiveness of the inter bay breathing also affect this phenomena plus, typically, but not always, the more the engine performance is increased the more blow by occurs which adds to the oil carry over issues.

The valley plate shown in the image earlier is not LPE designed, it comes with the Magnusson kit. What this does is remove the valley cover breather and now connects the driver’s side cover as was previously stated. The breather system of the LS3 does not have a PCV valve since it is an orifice controlled system.

On our higher output vehicles we use an oil air separator, specifically designed for this purpose, this can be seen here

So the catch can should not adversely effect the operation of the engine.

Best Regards

Thanks Graham I thought that if this was an issue that we should be concerned with you guys at LPE would inform us of the need to use one. It sounds like they are mainly a concern for the BIG HP Turbo Racing engines.

Good info Graham! If you want one of ours to test let me know, I think you will be surprised to see the effectivness. I'll have one sent out free.

Here is the proper diagram of the setup we use on the Magnuson's:


Only it mounts on the drivers side for the 2010 Camaro.

It is an issue with ALL engines, V6 & V8, especially with forced induction. All one needs to do is remove your throttle body and reach into the mounting snout with a clean paper towel to see the accumulation.

Your LPE setup will benifit from it guaranteed.

With high HP & high revving builds, it is an absolute must.

All good stuff!
Thanks Graham, your considerable wisdom is always appreciated!
(Note I didn't say age!)

Thanks Tracy for your contribution also! That's what its all about!

Now, what did I do with that global weather control ray gun?

Happy New year guys!!!
Thanks for all of the posts on this thread, it made my decision to get LPE to do my car much easier to make.

Can't go wrong w/LPE IMHO.
