What all are you guys looking to make for the vehicle?

Nick here from Mishimoto to kick off our development thread on the direct fit catch can kit for the 2nd Gen VT!
We've already had this beautiful 2019 R-Spec in for some initial R&D, and there will be plenty more info to come!
Feel free to shoot over any comments or questions you might have!
We're just starting with the catch can for now, but we've already poked around with the intake and have been scoping out the intercooler. No promises on if those will definitely happen, but it's something we're looking int!
Pardon this noob...
Could you provide a basic description of what the catch can does and how (and when) it will improve performance?
You got it! So, the main purpose for a catch can is overall protection over time for the top end components of your engine, specifically the intake valves. Basically what's happening, even on brand new vehicles, is that gasses from the cylinder can sneak passed the piston rings and pressurize the crankcase. Every vehicle has a way to relieve that pressure, via the positive crankcase ventilation valve, or PCV, which is routing the gasses back in through the intake, but the issue is that these gasses often contain blow-by, which is a nasty mixture of fuel vapors and oil droplets. This murky mix will stick and build carbon on just about everything, which isn't great for the valves, since sticky vavles means losing performance and efficiency over time. This is what the valves looked like on the basically brand new VT we had in the other week:
What a catch can does is it mounts in line with the PCV system to separate the blow-by from the crankcase pressure, leaving the oil and fuel vapors behind in the can and only clean air is being routed through your intake!
Hope this helps! Let me know if you have any other questions!
Thank you Nick. Really appreciate the education. Catch can is on the list!
You’re going to want a can for both the PCV system and breather outlet that connects to the intake.
Interesting that a brand new vendor convinced you to use a CC in one post, when the community as a whole has been recommending them for years. Please do some research and reading. Lots of other stuff to be done.

Thanks for the insight!
If using a can on any VT there needs to be one on PCV and breather sides.

Happy Friday! Just wanted to bump this thread up with an update for you guys! It's been almost exactly a month since our loaner Veloster Turbo made its way into the R&D facility, but we've been busy in that time!
The second generation of the Veloster Turbo might have been on the receiving end of plenty of updates, but the Gamma G4FJ under the hood remained mostly the same. With a new ECU and a bump in the compression ratio meant that it kept that same punchy feel, but it also meant that blow-by was still taking up residence on the intake valves. Make sure to scroll back up to check out the condition of the valves on this practically brand new engine.
Our engineer, Dan, is on the case though, and has a working prototype fitted up to our donor Veloster to send out for our standard 1000 mile test for a gauge on what we'd expect to catch with this system. Make sure that you head over to our Engineering Blog for a look at the full prototype kit, and make sure you keep your eyes peeled for the results from the road testing!
