My s3 v6 build

I was emptying my catch can every 1000 miles. There would be around 50-100ml of oily watery liquid in it. I don’t plan of plumbing mine into the TIP on this build. I had been advised by various people including those in the motorsport industry that plumbing it back into the TIP means your engine has to burn it off, oil fumes naturally reduces the octane...... how much of that is true I’m not 100% certain. But I wouldn’t want my engine burning off the crap I find in my catch can personally. I’ll be venting to atmosphere, many are concerned with the smell, I didn’t really notice it with mine.

. Does performance differ between brand ones and cheap ebay ones?

No difference in performance mate no, just make sure it’s a minimum of 19mm (3/4”) inlet and outlet. I know this is based on the 1.8t I doubt it’ll be any different on your VR6 engine. Ideally you’ll want one that’s baffled so as your driving around the contents inside aren’t splashing about loads. Another thing to consider is accessibility make sure you can easily get to it for emptying and cleaning it out occasionally. Majority of them out there will have a drain off at the bottom. You can always run a tube from that to anywhere, which is what I’ll be doing with my build.

Is an10 around 3/4? Yeah the nuke performance one comes with a tap and a 2m hose on the drain tap and also has a little dipstick so you can check the levels will have a look around at some other makes get one that looks decent

AN10 is 5/8 which is smaller. Nearest you’ll get to 19mm (3/4”) is AN12.

There are plenty out there, not expensive either, try searching for some aluminium fabricators, can’t remember there was a couple I found a while back. I’m actually selling my old setup but it’s more suited to a 1.8t with all the pipework and joiners, etc.

Yeah took me an age to find it originally. They don’t advertise themselves very well. Nice helpful people, just failed to baffle my original catch can when I ordered one from them, so I opened it up and baffled it myself. Good quality stuff to be fail to them and like you said..... well priced

Yeah must be a side business for someone there’s no address I don’t think look good quality though

@S3AMJ I vent mine to atmosphere and have done for a few years now. I vented mine to atmosphere after the rebuild so no poo was going back into the engine. In terms of the smell I did notice it when it was up near the strut brace so maybe getting into the car by the vents but I have now moved it to the back of the battery. I drilled a hole in the cone filter heat sheild and made a bracket and mounted it there. Had to take a we bit out of the battery cover to make it fit back over. 20191101 105154

Yeah mine was near the front of the engine bay too. My new one will be as well, suppose any fumes have disappeared by the time they get to the vents.

I will “try” and cover everything over with some of the covers. Not sure if running the catch cans to atmosphere is an mot failure. I will hopefully be getting my car MOT’d once I’ve had it back from Badger5 by a close friend of mine which is a “friendly” MOTer.

could you run the vent into the wheel arch so the smells don’t go into the cabin, although not a problem for me I’ve not smelt a thing In 7 months since the corona

So I’m ordering the Nuke performance catch can and drain kit after watching a few videos, ram air filter arrived today and it’s quite big think I’m glad I didn’t order the extra large one,
289050C7 FBF1 49F4 BC3E A531E53F790D


Loads to crack on with as planned to use my 2days off to crack on but can’t even do anything as I spent 8 hours in a tattoo chair last night and my shoulder is wrapped up tight
 
There’s a big influx of people using those ProRam air filters I’ve noticed. They seem good quality and a really nice finish. I’m tempted to change my K&N for one. Surprisingly quick cheap as well and “twin” cone.


Sent from my iPhone using Tapatalk
 
Yeah the “twin cone” is not full length the internal cone is probably only 2-3” inches deep and comes with a trumpet to take it down from 6”- 4” , I have seen good reviews on them and plus prefer the colour over the k&n one, also the ash hoses and clamps have turned up with the fmic kit and Ali pipe for the coolant feeds looking at all this and just want to get out and work on it
 
Not as deep as you would think but should be plenty

I might do a side by side test with Badger5 on these. Compare my current K&N to the ProRam on my new build.

The list is getting smaller mate, shouldn’t be too long now. Like I’ve said before, huge achievement doing it all yourself.

Time stands for no man as they say, I’m going to try and arrange for a meet next year, hopefully everyone’s cars will be together by summer time. Like a forum friendly track weekend or something. All depending on COVID-19 blah blah blah.

Yeah sounds good to me il be up for that,I have to clear some jobs off at work to help the boss out and will be booking a few Fridays and Monday off to give me a few long weekends to work on it,
Just seeing it come together does give me a sense of satisfaction knowing that I’ve done myself by asking questions and researching it
