Catch can install and throttlebody bypass

[Jimmie]

Does anyone have the write up or details on the two installs? Thanks in advance

I'm planning on installing a catch can fairly shortly, and will post something up, but in the meantime, take a look at Youtube. There's a ton of stuff there.

Are you talking about a throttle body coolant bypass?

Maybe this might help, member who did a catch can install:
Oil Catch Can (OCC) on 2017 G80 5.0L

 

[MG8]

I did both

Yes

On these cars in particular, what exactly are people expecting to benefit from a catch can?(unless you guys are later model years with DI engines. In that case, I understand that catch cans can help slow the carbon build up issue DI engines have). but yeah... if any of you guys are running regular old port injected 4.6's or 3.8's, I'd love to know why you're wasting your time/money on a catch can of all things lol.

Air from the crankcase contains oil vapor which over time will start to gum up everything in the intake. It gets worse as the car gets older and more blow-by is occurring. I think a 100-200 dollar catch can is worth it now than potentially needing a throttle body or any other component in the intake system down the road.

Any recommended brands??

Any recommended brands??

I would go with Mishimoto. Highly rated brand. You'll want a baffled catch can. Not sure if all Mishimoto CCs are baffled. Biggest one you can find.

Just like NSXNEXT said, Mishimoto is the way to go. I have some in stock and ready to ship. Message me if you are interested!

Even in non-DI applications, one can benefit from the use of a catch can. As oil vapor is drawn into the intake, and down into the cylinders, it promotes detonation by reducing the octane of the fuel mixture. It also fouls plugs and adds carbon build-up over time (despite port injection washing the backside of the valves, build up will still occur). I've run catch cans on all of my street cars (and breather tanks on my race cars). You'd be surprised at how much oil and condensate a catch can accumulates over a relatively short period of time, and it's better to be caught in an aluminum tube, instead being ingested by your engine.

Since it appears that the Genesis Sedan community doesn't really have much aftermarket support right now, it seems that you'll need to make one work from a universal application. I plan on using a billet catch can designed for an LS1 application myself, similar to the Mike Norris one that I currently have on my GTO.

My '12 RSpec had a lot of blow-by past piston rings causing it to use about a qt/2.5k miles. I drained about a cup of oil from intake manifold; and installed a cheap catch can. Didn't change blow-by, but otherwise captured much of the oil.
I have also deleted, by-passed the throttle body coolant lines. This is a very common mod with other motors. In the GM community with about 3-5hp dyno increase on LS motors.
OEM engineers believe that throttle body shaft icing can be a problem, which they can replicate in labs. My own experience is it is not a practical problem whatsoever.
OEM engineers also claim there are less pumping losses with heated intake air, simply because the throttle body has to open more with heated air. compared to denser cold air. Then one should have a highway gas mileage decrease with this mod. I have not seen such.
