We are releasing our new cast FD3S oil filler neck soon. This unit is a little more unique that most offerings on the market. It features a more indepth baffle system, and a drain back port for your catch can. Over the years we've seen many complaints about catch cans filling up on track driven cars, and we are hoping to solve that issue. Your oil catch can will need to be mounted higher than this return port, and use a check valve on this line. We are going to look at making a bolt in catch can/oil seperator to complement this neck. An aftermarket fill neck is also a necessity when changing your lower intake manifold to an aftermarket one, and with the release of our new units, it only made sense to start making these. Demand seems extremly high if we can hit our current target price of $199, so we might up production to 300 units from 200. We are doing one last fitment check today with a 3d printed model, as we made a few tweaks to ensure this fits every possible flavor of setup( DBW, oem throttle body, greddy elbow, our new throttle body elbow, etc etc). We should have the final pricing and production ETA later this week. It should be about 90-100 day range however.

Yes. I feel like this solution is long overdue. How does this fit with the factory intake, Throttle body, strut tower bar etc. for those of us that will be running mostly factory stuff but want to run an effective catch can setup?

 

We have checked clearance against every combination of every part with the following items: OEM lower, OEM upper, Our upper, Our lower, OEM throttle body, Bosch DBW with our adapter, greddy elbow, and our elbow. I have not checked with an OEM strut tower bar, because we don't have one, but it looks like it will clear based on photos.

 

It looks good. What size is the vent port near the filler neck?

Also, how are people measuring that their crankcase ventilation setups are working well on rotary engines? Do similar rules-of-thumb apply as the piston engine guys, where they might measure pressure and want to see less than 1psi? Are we stuck putting up with higher crankcase pressure numbers, assuming the rotary engine doesn't seal as well as piston engines?

 

10AN. Best way to know if its working properly is by how fast your catch can is filling up

 

I need one. Where do I preorder so I don’t miss this batch?

 

We haven't opened this up yet, will make an annoucement within a couple days. Just waiting on the ETA from our foundry so we can be clear on the delivery dates.

We were able to sneak a few more baffles into the final design too!
