Went with Bobs Ultimate. Almost plug and play. Had to heat sink the original intake and valve cover fittings onto the hoses but that was very easy. Looks awesome and professional under the hood with the red/blue AN fittings and braided hoses.So I have it narrowed down to either the JLT or Bobs separator and I cannot decide at all Iv also heard the JLT has been revised. Any opinions? Which one for you guys? :frusty:
OP, in my personal experience with my 850HP 2004 Cobra, which I must add....had over 100K miles on the stock engine, and our 2011 GT here at BMR, the JLT has worked very well.So I have it narrowed down to either the JLT or Bobs separator and I cannot decide at all Iv also heard the JLT has been revised.

Just a quick update for you as some PCV systems work better than others and ring seal etc. But after looking at the picture of the JLT mounted on your car it's only protecting the top half of the sysetm and exposing the rear line. The JLT mounts on a T right at the back of the valve cover and it only protects the up line and not the line going to the back of the blower.OP, in my personal experience with my 850HP 2004 Cobra, which I must add....had over 100K miles on the stock engine, and our 2011 GT here at BMR, the JLT has worked very well.
We just tore apart our engine in our 2011 GT, to build it better, and I noticed no trace of excessive oil vapors, or residue. We run a TVs Supercharger on 11 psi on this car. With the JLT in place, the car has over 300 track passes, and 20K miles.
After seeing these results, one of the first mods that I performed to my 2015 after the VMP TVS Install, was....yes, a JLT Oil Separator.
I am a big fan of the way this JLT piece mounts on my particular combo. It looks like it was meant to be there. This also came with a check valve, which was very easy to put in line during the install.
On that note, I use these JLT pieces on all of my personal cars, and we use them on all of our shop cars. We do not get them for free, we pay for them, gladly. My decision is simply based on my results with them, and my satisfaction with the quality and packaging.
I am pretty confident that the others mentioned in this thread, do an excellent job at what they are designed to do - but I wanted to give you some feedback from a suspension only company, and personal enthusiast perspective; with no ties to anything other than suspension for your S550.
I don't think you can go wrong with any of the brands listed in this thread, and others out there that have proven to work over the years.
Good luck with your choice!![]()
I really like this..how would you say this compares to bobs? I'm solely asking this based on the many people who run bobs separators and claiming how good they are at stopping oil but I love the plug and play and design of the UPR it looks like it works but how well does it?Bob's systems is $199.99 with anodized fittings or the UPR Plug n Play SC Catch Can with quick disconnect mount and Plug n Play fittings all the way around with Goodyear black braided hoses and Black Billet Hose ends is $149.99 for the top end system that mounts is literally 30 seconds and can outperform every single unit on the market without question.
It also has almost twice the capacity of the JLT and a hair more than the Bob's.
Here's a video on youtube that really displays the quality and features that set it apart and a internal build picture to see how far we have taken oil separation and maximize oil coalescing properties.
