Hey what's up guys!

B48TU OCC Kits are now live on the site!

For those not familiar, this is the release of our Competition Catch Can setup for the BMW G-Chassis and Toyota MK5 B48TU cars!

This will run a very similar setup to our already proven B58TU Competition Catch Can Setup and as you can see, it will allow your motor to safely vent as much crankcase pressure externally as possible!

For the guys chasing bigger power that also want to address the the PCV, we have also released our Solid Valve Cover Inserts for the B48TU that will ensure no crankcase pressure can make it to your valve cover!

This kit will vent through AN10 braided hoses and with our oil cap breather setup, it will also use our custom AN10 check valve banjo that will only allow venting under boost. This is more ideal than a fully open oil cap becayse you don't want to unnecessarily push oil and especially for the stock PCV guys, this still prevent the risk of created an vacuum leak!

This kit will fit multiple chassis including the A90 Supra, G29 Z4, G2X, G30, G42, G01, & G02!

As always, thank you guys for your constant support!

Hey what's up guys!

I released these a little while ago but never made a post so many may not even realize they are on the market!

What you see here are my Ross Racing S58 Check Valve Inserts as well as my solid inserts.

Just like with the B58 Gen1 and B58TU, our check valve inserts designs are proven to allow vacuum in the crankcase during idle but under boost they are forced shut which will delete the PCV under boost. This is a best of both worlds setup and will prevent your valve cover from ever failing internally.

Also available are our solid inserts which will fully delete the PCV and remove all vacuum from the crankcase. This setup may be more ideal for the track oriented guys that don't care about vacuum in the crankcase.

The most important thing to note is that under boost, they will both perform the same! They will prevent body from ever entering the crankcase! For the few cars that experience smoking on decel when fully removing vacuum from the crankcase, the check valve inserts will be three advised setup!

For the all high HP or even the weekend road warriors, address your PCV issues before they start causing bigger issues down the road! Remember, more boost equals more crankcase pressure and we all that too much pressure bursts pipes!

As always, thank you guys for your constant support!

Hey what's up guys! Matt from Ross Racing again and it's time to finally get around to releasing some products that I've had in the works for awhile now! Few more that I'll be releasing in the next coming weeks as well!

Many of you are already familiar with my VU Breather Cap for the B58 Gen1 so in the background I've been working on a similar setup for the N55/S55! Figure the N55 and S55 guys still needed some love!

Just like with the B58 setup, the N55/S55 VU Breather cap is a first of its kind and will allow vacuum in the crankcase during idle but under boost the check valve will be forced shut thus deleting the PCV. A best of both worlds setup!

The benefit of this is that while most cars run fine with vacuum completely removed from the crankcase, some cars are more likely to smoke, especially on decel. With the VU setup, this is minimize as it still allows your motor to retain vacuum when needed! This will also help keep smell very low as it will only vent under boost (usually when moving) vs when fully deleting the PCV, the motor needs to vent the crankcase pressure all the time! Basic, in every and any situation, the VU setup will be the better option when addressing the PCV!

Big shout-out to Emrah Gtr for testing this on his S55 for us and also props for his clean custom OCC setup!

Now live on the site and as always, I appreciate your continued support!

What's up guys!

Big shout to out Sven for sending over these photos and videos! He installed our Ross Racing B58TU Check Valve Inserts and coupled it with our Ross Racing Square Competition Catch Can.

For those that want to still retain their engine cover, as you can see, it is still possible with only slight modifications. Sven did a really clean install and only needed to cut the engine cover in one area.

No reason to sacrifice venting for "looks" by using a baby AN6 hose just so you can route it under the engine cover! Especially for the guys chasing 600hp+, venting through an AN6 hose on the oil cap is a HUGE bottleneck.

You wouldn't run a 2" diameter exhaust on any 400hp+ car so why would you vent crankcase gases through a baby AN6 hose on a B58?? Do it right the first time and go Ross Racing!

Our kit was designed for Form AND Function vs just Form from those guys. This is why our OCC kit is the only one on the market with a Baffled Oil Cap that also uses our first of its kind, custom Check Valve Banjo setup that only vents under boost. No need to worry about pulling in unmetered air and potentially creating a vacuum leak with an open style banjo; especially if you're stock PCV or run Check Valve Inserts. So again, do it right the first time and go Ross Racing!

As always, thank you guys for your continued support!

What’s up guys! Matt from Ross Racing releasing another first of its kind which is the Gen1 Check Valve Inserts!

As most already know, the Gen1 valve cover ports have an odd shape that make it difficult to design inserts for. I finally got around to designing check valve inserts for the Gen1 guys that will fit these ports! What this means is, there will be vacuum in the crankcase during idle for stock PCV function but the check valves will be force shut under boost which will in turn delete the PCV under boost. This will also address it from the head so the valve cover will NEVER see any boost!

The best part is that it can be ran in tandem with my VU Breather Cap so that you’re also able to vent properly from the lowside of the PCV without running the risk of having a vacuum leak! Running them with the VU cap ensures the highside port isn’t the only port venting all the excess crankcase pressure so there will be less crankcase pressure in the system overall!

The VU Breather cap was the first of it’s kind but the downside to this was that it still allowed boost to enter the valve cover through the plastic welded channels which meant the valve cover still saw boost and could still fail internally (plastic welds cracking). This eliminates that risk!

Along the way I also decided to improve on the VU Cap design and while I kept the overall Cap Billet AL6061, the middle prong is now made of CNC’d ASTM A36 material. For those not familiar, ASTM A36 is a very strong carbon steel that is even stronger than SS304. The downside to carbon steel is that it is corrosive but my simple fix was to have it nickel plated. This will prevent any risk of rusting or corrosion while also giving it a pretty cool look imo! This improvement is meant to minimize the risk of the middle prong snapping from improper install.

I also added the option for a Click & Lock version of the VU Breather Cap which of the two, the Click & Lock Version will be easier to align and install for the less experienced installers.

As always, thank you guys for your constant support and look out for my next post for the S58 guys!

Introducing the first of its kind, the B58 Gen1 Check Valved PCV Breather Cap, aka, the PCV Breather VU (Version Ultimate)!

This new breather cap will be a game changer in more ways than one! Similar to our B58TU Check Valve Inserts, our PCV Breather VU during idle will still allow vacuum in the crankcase. Under boost is a different story. Once boost tries to get past the check valve setup, it will force the valve/ball shut which will prevent any boost from entering the crankcase. In layman’s terms, stock PCV during idle with vacuum in the crankcase but under boost the PCV will be deleted! Best of both worlds! This will also mean little to no smell!

With this setup there are special requirements though. With there being vacuum in the crankcase, you cannot just run a regular open style banjo as this will create a vacuum leak. This is why we designed a special check valve/PCV AN10 Banjo that will stay closed during idle to prevent a boost leak but open under boost to ensure the excess crankcase pressure is able to VTA! Two custom designs working in tandem with each other to create the ultimate solution to PCV issues! Sounds simple enough once explained but anything but, otherwise others would have already thought of it!

This kit will come wit the ability to either vent through 1 port (other port will be capped) or vent through 2 ports. As mention, the AN10 banjo supplied for each port will have a check valve/PCV function that will stay closed during idle (vacuum in the crankcase) and opened under boost to expel excess crankcase pressure. Best of both worlds!

ONLY COMPATIBLE w/ motors with a functioning PCV! If Headports have been plugged, this Breather cap will not function as intended because there will no longer be any vacuum in the crankcase.

As always, thank you guys for your constant support!

What’s up guys! Matt from Ross Racing here with what I hope will be a huge announcement!

After months of testing and tweaking, we finally feel it’s ready!

Introducing the Ross Racing B58TU OCC Kit!

This kit, we feel will be the best on the market and it won’t even be close!

Our kit will include our tried-&-true Ross Racing Competition Catch can which have been performing beautifully on the Gen1 B58s running our valve covers, with some guys running 45+ psi of boost! You will also noticed that we have designed an all new squared Competition Catch Can which was deisgned similar to our standard circular version but squared! One more option to choose from depending on your preference! When it comes to venting and baffle design, you won’t find a better option out there than our Competition Catch Cans!

You’ll also notice that there are a variety of OCC braces. Like I said, we have been testing! While not pictured, we have an OCC setup that will fit a variety of cars including the BMW G2X, G30, G42, G01, G02 and Supra A90/A91! This will also include a top mount OCC setup for most options!

Our kit will be the most complete kit on the market and will also offer the most venting in the safest way possible! So no, we will NOT be venting from the lower CCV Port because the point of our kit is to solve crankcase/blowby issues, not introduce new ones! Most of you have already seen my spiel on the idiocy of venting from the lower CCV Port so I won’t stay on that topic but I would like to also introduce you guys to my new, first of its kind, AN10 to AN10 PCV/Check Valve Banjo fitting. This new banjo will attach to my best in class Oil Cap Breather and allow for venting only under boost while staying shut during idle. If you’re stock PCV, this will prevent the risk of a vacuum leak during idle and if you’ve deleted the PCV, during idle, venting from the valve cover PCV port will be sufficient!

Our kit will also only use AN10 hoses as we want to ensure your car is able to vent as much crankcase pressure as possible! No bottlenecks!

As always, thank you guys for you constant support! Means the world!

What's up guys!

Want to introduce to you guys my new B58TU Valve Cover Check Valve Inserts!

Now the question you’ll ask is how these work and the answer is very simple!

Unlike Block Off Pins and Headport Taps which delete the PCV completely by completely closing off the headports, my CVIs (Check Valve Inserts) do more! My CVIs are spring and check ball loaded and will be open during idle by vacuum. What this means is that during idle, there will still be vacuum in the crankcase. Under boost is a different story. Once boost tries to get past the check valve setup, it will force the valve/ball shut which will prevent any boost from entering the crankcase. In layman’s terms, stock PCV during idle with vacuum in the crankcase but under boost the PCV will be deleted! Best of both worlds! Block Off Pins are a lazy design in comparison!

I’m not the first to do this but I designed mine to be more unique. I’ve designed mine to be pressed in like the others but mine is also fully removable. To keep it in place mine uses custom FKM (Viton) O’Rings and there will also but a small hole on the sides in which you can use a pick tool to remove them if needed. On the TU valve cover ports the middle port is also shorter than the two outer ones so I also added adapters to help keep everything flush once fully inserted. The outside adapters will be labeled “L/R” meaning “Left or Right” port and the middle Adapter will be labeled “M” meaning “Middle” port. Very simple install! Just make sure that with the valve cover upside down to inserts the CVIs, the logo and labels on the parts should be rightside up (readable to you) when inserting them.

If it’s a new valve cover then lubing the orings will help but if it’s a used valve cover, lubing the orings will not be as necessary.

With this mod, the more venting from the valve cover the better so if you haven't already, this would be rhe perfect time to start venting from the oil cap with my Oil Cap Breather!

As always, thank you for your constant support guys!
