rx catch can [options]

what's the difference between a single check valve and a dual check valve? and why do you prefer it?

also what's a breather oil fill cap [optional] how do you feel about it? Do I need it?


single http://www.revxtreme.com/rx-catch-ca...le-check-valve

double http://www.revxtreme.com/rx-catch-can-dual-check-valve

if you look in any one of those links you'll see the optional breather oil fill cap.

Thanks in advance

Dual is for forced induction

I actually have a question regarding these options. Can you run a dual check valve can on a N/A engine?

I know the dual check valve is for boosted applications for when the intake pressure goes positive but is it still possible to run the dual check valve can on a N/A engine?

My reasoning would be someday I may decide to put a supercharger on my car and I don't like spending the same money twice for the same basic mod. So I'd be willing to pay a little more now and be set no matter which way I go with my engine.

If you run the dual check valve on NA you cap one of the three lines at the can.

Just looked back in my PM's cause I asked Tracy this a while back. When did his account get suspended? SC2150

Be aware that they are running a few months behind on filling orders. I ordered my car on 3/25 and I ordered the catch can right after I ordered the car. I have the car, still waiting on the catch can.

Get the Dual catch can, it caps easy.

I noticed lately that Tracy gets banned every now and then. Maybe it's a sponsor payment thing?

Whatever happened to Hendrix-engineering while we're on the subject?

Dual valve is for forced induction (supercharger, turbo), single valve is for naturally aspirated applications. Without getting too technical, the breather cap helps the catch can be slightly more effective.

Yes, you can get a dual valve can and cap off one of the outlets until you install your supercharger. When that time comes, just uncap it and hook up the hose.

Concerning RX catch cans specifically, be aware that they are running way behind. The backorder is currently running about 8 weeks.

Wow thanks for all the good info everybody - I couldn't have asked for more.
Last question I have is if I can find one used is there any worries with them?

On a PD (positive displacement) supercharger application, a single can is perfectly fine. The only time you really need the dual port can is with a centrifugal S/C (like Procharger, ECS, Etc) or a turbo setup. The reason for the dual can with check valves is to prevent any reverse flow due to the constant changes between vacuum and boost. With a PD supercharger, the inlet side will stay in vacuum.

As stated, the RX cans are on a heavy back order. I suggest going with the Elite Engineering catch can unless you need the dual valve can.

Please feel free to call, PM or email me anytime with questions.

Best regards,

Tyler

Nope...as long as it's pretty. That's about the only thing that can go wrong with a used catch can. Make sure it's empty, clean and the plug surfaces are clean so that when you put the hoses on, they don't make a mess and seal correctly.

Nope. As long as it's one of the "intake" valves. Which would be the two furthest away from the mounting bracket.

Good luck and let us know if you got questions!

Good point Tyler. I didn't think of that but it makes perfect sense to me since all of the intake plumbing is located before the blower on a roots type.

Where as on a centrifugal or a turbo has intake plumbing between it and the throttle body.

I went with the Elite Engineering... put it on yesterday... looks like a factory piece, and appears to be very well made.
