Thanks for the concern mate!
When a mate and I measured intake temp and other stuff last week prior to the FMIC install we also logged the boost and we saw 1.58 bar in 3rd and 4th gear pulls.
Low boost then eh?
You'll want more boost/torque...then you may hit problems.
I too raised some concern to those dots but there were two other cars there that had excactly the same 'dot-n-jubilee' joined sections in the shop that day/days. Same IC too btw. One was a 350hp A3 1.8T running 1.5 bar and the other was a 300hp A4 1.8T...both of them covered many many miles without any issues...
The peak power isn't the problem. It could be running 600 BHP for all it matters...what seems to the the problem is how quickly the peak torque boost is applied...mine was making 1.85+ bar boost and it went from nothing to full torque in 500 RPM...so the pressurised pipework gets shock loaded...and pops a hose off.
Joints are always the weak point in any pressurised system...and they will take much more pressure when pressured up slowly. Shock them, and they'll let go.
A K04 S3 is capable of delivering high pressure, very quickly and it can - and probably will - cause problems.
Been there...done that...got stranded in the Scottish Highlands on an Audi-Sport run!
It may be Ok...but if it were me, I'd want either swaged ends to the pipes or a full ring of weld (how I did it) and stronger clamps as Jubilee clips WILL work loose over time.
The shop told me this when I asked about the puny size and material on the jubilee's: Sure you can buy more expensive stuff that looks good and can be tightened even more, but you won't need it.
From experience, you do.
It's your car though...
They did tell me though, to drive around with a couple of extra jubilee clips and 6mm socket the first few weeks IF there was a hose that blew...And then he told me that if something goes wrong it will happen almost imidiately not later on...
So there are concerns over the reliability of the Jubilee Clips then?
You blow a hose off...what do you do?
Limp home with and engine check light on, making next to no power and breathing unfiltered air?
Or simply whip the bumper off at the side of the road and fe-fit a new clip using the box of tools you obviously carry around? (who doesn't?)
Or...do you fit some 'proper' clamps and forget about any problems, kick back, have a beer and don't give it another thought?
Hmm...
Seriously...if you blow a hose off, it'll be on the worst possible day inconvenience wise, in bad weather etc and really spoil your day.
Just give it some thought. Especially if you are having the bumper off again in the furure.
Hmmm, what to do now. I think that they did a poor job cutting the hoses, making brackets and the jubilee clips weren't mounted very need ie turned the same way etc. I WILL have to do this again 'cause I'm anal about those things. Must be 100% otherwise I'l think about all the time..hehe. So I had a look at those Mikalor clips you mentioned and they look the shizle...very expensive though. 30 pieces = 1200 NOK...
It's a wise move Dennis.
The Mikanor clamps (go for Supra Pro - stainless ones) are indeed the Shizzle.
I'd opt for stainless too as they will corrode being in the air/water all the time and you really don't want to come back to a rusty mess in a year or so.
At least you know you can whack the boost up when you feel like it and not worry about the hoses slipping off - but you really should consider getting those pipes ring welded too.
Those dots will allow Silicone hoses to slide over them if the clamps work loose...this simply cannot happen with either a swaged end, or a fully circumferentially welded pipe.
Well I won't be able to buy them in time for the VW/Audi trackdays next weekend because I have the adjustable tie bars arriving late tuesday night, full alignment early wednesday (330 pounds...I was shocked to be honest) and a complete change of discs, pads, lines and fluid which I have to do thursday.
Those cars, those cars...
Spend, spend, spend eh?
