To be honest in my opinion it offers NO power gain.having said that I have a theory that if your mixing hot oil and water condensation vapour with fuel do you get a better burn then if you were burning a clean fuel?oil does burn but does it burn efficient?and if this catch tank is useless why to touring cars and the likes use this system?ive seen and fitted catch tanks and breather systems since late 90's and they've been around I guess before the 80's on the ford touring cars so there must be a feasible use for them.i can only speak from my experience is that I get almost,no I get no jerk from my car from cold as opposed to all the m3's I drive at work.i do find it really smooth as opposed to the jerk I used to get.now I'm not saying this will cure anyone's jerking from cold to warm pull off but my car seems fine.anyone wants to compare are more then welcome to come try mine.thats all I can say really.

Ejaz would you agree with my statement seeing you have one too.
What's your honest thought?

Adem,

I absolutely agree with what you have said in the posts above. This is not really a performance mod unless your FI but for people running a CSL intake or similar this is a great Mod and it prevents all those water and oil vapors from recirculating into your motor.

When i empty it, which is not very often, since i hardly drive the car more than twice a month....im glad all that crap doesnt end up in my motor any more.

Hi Adem,

I am not in doubt whether it works or not. I am sure it does. For me it was just interesting to hear how much it "catches".

I was thinking about doing this mod for a while now. Im probably doing it now in the off-season.

No worries I was simply explaining what I feel I got outta the setup
Go for it it's worth it
