In the tech section many talk about installing catch cans. Has anyone with a ATI procharger installed one, where and brand. One person showed pix of his heads removed and the pistons were black as can be. 2 were cleaned to show how badly chared the others were. What pix there were show them mounted right where the procharger is. Any feedback greatly appreciated.

 

I'll let you know , Im having one put on in the next few weeks

 

Very important on a FI application, and even more important is that it is setup properly. Here is one on a Maggie GTO. We have a procharged C6 in the shop now & we do them very similar. Do to the room needed on supercharged applications we mount the can to the brake booster.



Just ask questions if you want more info. The PCV system on our cars is the most misunderstood mod there is & far to many are done wrong. There is even a tuner out there plugging it all off & running open hoses from the valve covers down to the ground where they suck up dust/dirt/water/gravel & who knows what else directly into the valve train! Slowly destroying the engine.

 

Thanks for the info. When the C6 is finshed can you show a couple of pix on how you did it for reference. I'll be ordering one soon when I have a better understanding on the proper proceedure. I don't run mine hard but do want it to last.

 

I just put one of mine on a Procharged C6 and will see if I can get a few pics for you. You can get some info on my catch can at:

Where are you attaching the hoses on the Maggie side? And is the catch can still effective with that length of hose run required to mount at the brake booster?

 

Hose can be any lentgh...the key is the cooler surface area in the can for the vapors to contact & condense to droplets. On a FI application the vac source comes from the induction tubing in front of the blower or turbo. The crankcase vapors are still pulled from the same fittings as OEM & the breather replaces the OEM fresh air source.

 

What happens to the Oil that gets caught by the can?

 

Every few months you drain the can & dispose of it.

 

You want the lines to be as short as possable .

The longer the line the more chance you have of blockage on either line .

As the line droops and rises , everywhere the line droops oil will settle .

Ya gota remember , oil is heavy and you can only push/pull it uphill and downhill so far with the vacume of the motor , it will settle at the lowest point .

Its only a matter of time before that catch can mounted by the brake booster with 3/8 id lines that run around the back of the motor clogs up and becomes useless .

Ask me how i know :P

 

Sorry you had an issue....but with hundreds of them on our builds over time we have even mounted them in front of the radiator with never an issue.....the oil moves through the lines with ease unless there would be an unfiltered opening allowing dust & dirt in to clog it up. It is also important to NOT use regular fuel line as it can collapse under vac....emmisions rated will not.

 

Here are a few pics from a Procharged C5 Z06. Hopefully my computer prowess lets this work right The can is black on black so you can not see the detail, but should give you an idea on what you are looking at.

He Did It ! ! waaahoooo !

 

Thanks Mike. Pictures helped a great deal

 

Calm down zoomz and get back to work

No problem on the pics and just let me know.

Mike,

The Procharger installation manual I got with the unit instucted us to cap off the intake manifold port with a cap (I have the boost switch for the methanol injection and Boost-A-Pump connected to this port, but it does not connect to other crankcase venting.) The PCV (valley) port is to 'T' off to the passenger side valve cover vent port, and the other connection hose is to connect to the Procharger intake air filter. This routing makes me wonder where the cleansing intake air is to come from.

On your installation photos, am I correct in that you have the catch can installed as it would be on a non-forced induction car, that is with the PCV valley port connection through the catch can to the manifold intake port? Did you install a pressure check valve inline with the manifold line, in order to prevent reverse flow?

What is the correct way to install a catch can on a F/I car? Some mentioned using the intake manifold connection (with pressure check valve), and others mentioned not using the manifold port.

Any insight would be greatly appreciated.

 

On FI applications we cap off the intake vacuum port as the instructions tell you, pull from the intake tubing in front of the head unit (or turbo) as the instructions tell you, and we add either the mini breather in the oil fill cap, or a fitting in the oil fill cap leading to a remote located breather. We have the PCV valve inline to the intake tubing to prevent boost blowing oil back into the intake & the breather location allows filtered fresh air to flow through & flush the crankcase and the LS6 valley outlet is a good design that is retained. In some cases we run 2 cans in series.

 

Tracy touched on this and I will throw in my 2 cents.

On any forced induction car with or without my catch can there should be a one way check valve in the PCV hose. I know APS supplies one as does Andy with the A&A kits and most likely a few others. I know some do not and not sure why. I know the PCV valve will hold some pressure, but can not be depended on for a complete seal.

My can does not have such a valve built in for the above reason in that it should be part of any FI kit out there. If one is not used it can be sourced rather easily.

On the breather hose that goes to the air duct on the C6's or the port on the TB, it does get blocked of per all FI instructions I have seen and from there a couple choices.

One is to just add a breather as shown which has a down side of getting oil fumes at times due to the oil vapors being let out to the atmosphere. This can also leak if the element becomes full enough of oil.

Second is to run the factory breather to the inlet area where there is no boost. With a proper check valve in the PCV and good ring seal, this should work fine. In situations where oil is still getting into the intake tract via the breather hose due to boosting the crankcase, you can put a second catch can in the breather line also.

I am just not a big fan of using an external breather due to the fumes on a daily driver, but it some cases it is needed or just less expensive.

Hope this helps.
