Damn. Didn't realize a catch can setup would cost $600. Might go see what JTran recommends

You know 'cheap' is not in me. The engine bay is so clean now I wouldn't want to ruin that. I just didn't realize it was going to be $250-300 a can to setup. I don't see the double can working too well so I was looking at two single cans. Next thing is where to mount them.

Still running it by JTran to see what he thinks about venting everything.

You getting in line for his radiator overflow tank? I might depending on price and I would want him to add a site glass to the outside so I would know fluid level without removing the cap.

I hope I'm in line. I posted on their FB that i want one. A sight glass would be the bees knees.

I was one of the first, if not the first to order one of the rad overflow tanks from that other company that were going to be made a GTM time ago. They even had/have my credit card info...

I also know that you do not do cheap, that's why I didn't bother posting catch cans from Summit in the other post. I just gave you the link to the cheap one for laughs. Seriously, how the heck can they sell that for $12?

I miss so much not being on Facebook sometimes, how does one get in on their coolant tanks? I am uploading a reving video right now although the sound quality sucks as the camera has a hard time picking it up, I should have used my go pro come to think of it.

I would appreciate it man, If I can get rid of that stock tank and that power steering reservior I would be happy. If I ambitious I might T off those lines and run them down the car and relocate one of those filters that we are currently using. I dont run catch cans on our diesels, but then again they are dirty and no one cares about a little blowby, most just route the line down along the frame and zip tie it off.

No problem. It occurred to me that we could save a little money by reusing the filters Sasha provided.

Thread Jack...

I stopped in on the JTran dynoday Saturday and Amber informed me that they should be getting the materials in for the overflow tank this week and start welding them up. She seemed pretty confident they could add a site glass too. I didn't get any pricing since they were busy with the dynoday. Heading up there this Friday to get the post cat O2 sensors deleted from my map. I'll inquire more and revert back.

Here it is, sounds I would say 90% factory, this is after I removed the Post cat O2s and change the cold fueling tables. Listen for yourself, again hard to hear and I dont want to drive it like that until I get a catch can. I think a single catch can setup would work just fine in our setup. I doubt your going to have enough blowby to warrant a big dual can setup. But again it would be nice to hear from one of the guys who deal strictly with this engine.

Nope not on that front, I just installed my 3" boost tubes tho and am going to be out tuning that today.

To be honest with you I am not sure if I will ever bother with the catch cans, my hunt is very small now after changing up the other things. Catch cans arent cheap. Maybe over the winter I will look at doing it.

So in recap. Delete the post cat O2s and changed of the old start table? That's all you changed right?

Yes delete the post O2s and change the cold fueling table to the main fueling table because I think it switches between the two more than Uprev would like you to think.

Not sure if this is the answer or if you have already thought of this. This could be because the BOV you are using vents to atmosphere rather than recirculating. The 370 uses a maf so it could be messing up your readings causing you to run rich. Back when I had my turbo honda, I never had this issue cause we used a MAP sensor rather than a MAF. Here is a link for reference.

Can someone explain, Recirculating BOV to me please? | DSMtuners
