Please forward ALL calls and texts to (850) 512-4336 or email me directly at Blake@850fab.com. Until further notice, there will be no wait time estimates. This includes machined and 3D printed products. We are in the process of closing on our new house, clearing current orders, moving, and on top of everything getting a brand new shop built in the next few weeks. We have a TON of work to do and while we are not turning away orders, we are asking customers to please be patient and understand the stress we are under. If you cannot wait, DO NOT ORDER. We appreciate everyone who has blessed us with orders. Thank you!
"Catch Cans" are used to allow the crankcase to breathe. The natural operation of the engine creates a positive pressure within the crankcase by some amount of combustion gas/air to seep beyond the rings. There is also a natural force acting against the piston rings as they travel up and down the cylinder bore. During this time, you want to remove as much pressure as possible from the bottom of the rings. Allowing the crankcase to breathe has many positive advantages which most PCV systems are not designed to handle from a performance aspect (especially once you add forced induction:
Decrease in blow-by
increased ring seal
less opposing pumping forces under the pistons
opportunity to run low tension rings for increased power output
lesser opportunity for crankcase pressure to create oil leaks such as oil pan, front and rear main seal
EXAMPLE: Lets be a little exaggerated so you get the idea. Inflate really anything to its maximum inflation. Hard to push it right? Remove half the air from it. Easier to push down right? Now do this over and over 4000 times a minute at the same stroke distance and see which one wears you out the quickest LOL. This is an exaggerated example but it gives you an idea of whats happening in the crankcase.
Stock PCV systems simply are not designed to remove the pressures in the crankcase once you increase the performance and cylinder pressures of a modified engine.
850Fab is here to offer engineered solutions for crankcase ventilation. We will have many variations and will be continually updating with new designs. For now, I will be taking orders for 6(L) x 4.5(W) x 5(H) Catch cans or any size within 1" of any dimension at the listed price in any configuration you would like including two mounting bungs. You can put the AN bungs on the side, front, back, or top with no upcharge. All tanks come standard as internally baffled. The baffling wall on the inside allows the crankcase gas to separate the oil and water and only allow the vapor to exit the atmospheric breather filter. I do not set them up with drains. I prefer to use a vacuum pump to suck the oil out. There is no mess involved and no valves that can leak. IF you do still want a drain, I CAN add one. If your setup requires a recirculated breather back into the induction system, please let me know. Once you place your order, please contact me via EMAIL at Blake@850Fab.com so we can discuss your configuration. My goal is a 1 week turn around!
