So with less and less space available in my engine bay with the Rotrex system and my GotPSI? intake manifold I am running out of places to mount a catch can. Can you please post up photos of where you mounted yours and what kind of can it is. I may weld something up but OTS is always easier.

Tnx

 

Disregard catch can, acquire slashcut tube in your exhaust.

 

I'm familiar with the slash cut idea. However I still want a catch can.

 

You're a ******* *****.

Here's my catch can bitch

Supersiourioeus why you want catch can

 

I have mixed feelings about the slashcut, I havent seen any evidence that its shape could even manage to cancel out the backpressure of the exhaust.
Although I do see the beauty in not having a filter to clog or having to empty it of oil and such.

 

Aerodynamics. How do they work?

 

Mosts tests I've seen done generally tend to register right about or slightly below atmo. So it is cancelling it it out, but not necessarily creating a vacuum to suck out the gasses.

But if you consider the fact that you get all the benefit of an atmospherically vented crankcase system, with none of the BS of a catch can, it is still win.

 

The world is my catch can lulz

 

lol QFT

 

You guys are silly.

I plan to do a slash cut similar to Bob's with the incorporation of a catch can. I can't just route my valve cover directly to the exhaust and expect to pass any sort of tech inspection.

So... locations pls and tnx.

 

Mine is where the power steering reservoir used to be, pretty low. Got a pic somewhere.

 

Slashcuts are specifically outlawed in the SCCA GCR.

My catch can is located where the washer fluid tank would normally sit, but I am actively changing that part of the car right now. Eventually I'll probably do a separator system with a sump drain and some sort of vacuum pump.

 

ORLY?

For environmental purposes, or because of the chance that some of it may dribble out the exhaust pipe?

 

Yeah I'm playing around in that area right now. My FPR is mounted to the fuse box mount so it makes space quite restricted. I think if I move a few fuel lines around I should be able to mount it to the firewall with riv nuts,

 

Probably for fire hazard, honestly. If something in the motor lets go, there's a strong possibility of a lot of oil being dumped directly into the exhaust.

 

Sav... I'm considering blocking off the pass port and drilling out the drivers side to accept a larger AN fitting. How do you have yours wired? I've noticed a lot of oil in the can after track days (solid thick oil... not blowby I know the diff.) and want to help eliminate it. How are you getting around the oil out the pass port on left turn issues?

 

Well isn't the exhaust a good place for a lot of oil? So what if a gallon of oil burns in the exhaust? It won't blow up the car

 

Well when you're competitors go for on off track excursion after you gave them the ol' James Bond smoke screen, I'm sure they will be coming to give you a high five.

 

9.3.38. OIL CATCH TANKS, FILTERS, AND BREATHERS
Oil holding tanks and engine breathers, whether directly or indirectly
ventilating the crankcase, and all transmission/transaxle breathers shall
be equipped with oil catch tanks. Minimum catch tank capacity shall be
one U.S. quart for the engine and transmission/transaxle. Oil holding tanks
and oil filters may be mounted in the driver/passenger compartment. A
metal bulkhead shall prevent exposure of the driver to oil spillage. Oil
catch tanks shall vent into the engine compartment or outside the driver’s
compartment. A crankcase vacuum breather that passes through the oil
catch tank(s) to exhaust systems or vacuum devices that connect directly
to exhaust systems is prohibited.

Did not read that until now. From experience I can say I don’t believe it is any more of a fire hazard if your engine lets go. It does make one hell of a smoke screen however as it significantly reduces the amount of oil that gets laid on the track. I guess to be SCCA legal Id just put a breather on the end of my slash cut hose and let it drip on the ground.

I’m also pretty sure most the breathers sold are not the minimum required one quart.

Both stock ports are capped. I have a single 1/2" NPT fitting in the TOP of the valve cover, with a 5/8" reinforced nylon hose to a catch can. With the stock barb hooked up I would pass a huge amount of clean oil to the catch can, with the big 1/2" NPT barb it passes virtually nothing. I have also drilled out the "small hole" as large as possible.
