After getting some PMs and questions about this setup, I want to clarify something:

The old oil return line is NOT used as a oil return line, it becomes a air venting location in this setup.

Some people are thinking that this is there as an oil return line for the catch can, IT IS NOT, it is a VENT LINE. There is NO oil return line from the catch can back to the oil pan in my setup.

Any oil that accumulates in the catch can is drained later with a valve at the bottom of the can and then discarded.

Remember, the goal is not to 'catch' oil in the catch can and return it to the pan, the goal is to vent the pan so that air can escape without pushign oil out with it. The catch can is in place to catch the small amount of oil that may get by our venting and/or oil 'mist' in the air that we can accumulate in the can while letting the air get out. Ideally oil should never get to the catch can if the oil pan is vented properly.

Could you maybe show a simple illustration from Microsoft Paint or something

So for the rear oil drain you have a -10AN hose that runs up to the transmission area?

What is the 2nd line that's coming off the catch can that's going towards the firewall?

Dale-

I mis-spoke, I'm only running ONE VITON line to my oil-filler neck.

Have you (or others) found a solution for those of us with stock twins ?

Thanks,

please tell me you have something covering that battery terminal post. it looks like its only about an inch or two away from the catch can lines. if that grounds out against anything....big sparks...maybe fire.

I think it's just the angle you're looking at it from. The fuse box appears to be secure as well.

nice catch can setup.

I don't do near the track events you do, but wanted to do it once and do it right. The only difference is I used the cheaper push loc hose and fittings, and just used a 1/2 npt tap to put an -10 an fitting in the re speed filler neck. Works great, I get nothing but moisture out of it for the most part.

That sounds like an excellent way to do the hoses as well. The lines do not need to be high pressure, so push loc would work great, and be a easy to use and affordable alternative.

here is a question, when is it necessary to get a catch can?

Sure, when I get some time I will post a diagram similar to the one I did for my grounding kit install thread, with overlayed graphics of where things go.

once you start dumping a lot of oil smoke out of your exhaust during hard cornering... usualy happen on the track only, not really during street driving.

So where are people venting for the right side of the block when you're using the twins ?

I too asked that very same question in this thread back in 2008.... And I have also asked it in other threads of this type, I have not seen a definitive answer.

Im doing this same thing now with mine. Heres what I did the the right side and too little room to use a normal fitting thanks to the wastgate on my car.

Ill post pics of it all finished when I get the rest of the parts back for the car.

Very nice thread...and yes I know this thread is 1-2 years old...it's just good to see what experienced track and AutoX racers create through wisedom/trial and error.

If you don't mind me asking - Could you custom weld an aluminum filler neck exactly like yours for me? (you may need to market this simple design and profit from it)

If so how much would it cost me if you custom created/welded me an aluminum filler neck like yours (my engine is S5 13BT but the spacing between your filler neck as in comparison to mine is almost exactly the same, if not it is the same).

Thanks and much appreciated

Thanks Mattew,

I purchased the actual neck and then created the extra port and baffle for the line to the catch can and had a local shop weld it in place.

The best thing would be to get the original maker of the neck to make another 'catch can' version, with my changes....but I dont rememebr who originally made it. LOL

Re Speed made that oil filler neck. I'm not sure if they always stock. If they don't they do some Group Buys now and then for it.

Damien emailed us and told us about the thread here.

We most certainly could work up a "Damian Racing" version of our filler for those that want to add the large -10 line and catch can.

We are finishing our current group buy for the next batch of fillers this week. I will start looking into the new design and should have something over the next few weeks.

We have been doing these on group buys only for the last few months to cut back on inventory levels. The plan is to bring them back to "in stock" over the next month and may add this one to the line up.

Thanks,

Billy,

I already ordered, but haven't received my oil-filler. Can you make mine the "Damian Racing" version ?

Thanks,

Looks like this could be used for the filler neck? I'm not sure what the second hole would be used for in Damian's setup though...

Good post, yeah that would be a good solution for the filler neck. I wonder if he say my thread here and got some ideas ;-)

Hey Damian, I have this same setup on my track car (almost identical) and after the cars first testing session on a right hand (clockwise) track, its still filling a 1Litre catch can and making a right mess of the engine bay/windscreen after about 5-6 laps? The car is making about 345kw on 17psi but it does the same thing on low boost of 11psi. Only ever fills the can on the track and never on the street. And its only happening during HARD cornering laps. If im lazy around the corners, its not an issue.

How is yours holding up? Can you offer any other advise?

Pics of your set-up would help!
