F**king things, i am so pi**ed off, the last week or so, i have had mikalor clamps come off more times than i care to remember.
As soon as this does, car obviously cuts out as no air being forced through intercooler.
I have done them up so tight everytime, roughed up the polished tube where the silicone joins it to give it some bite, and still comes off!
Im only at stage 1, whats going to happen at stage 2 and 22 psi?
Thought mikalor clamps were the dogs danglers!
Been left pushing silicone back over pipe at the side of the road, in the dark, then creeping home at the lowest possible speed and revs, so i dont have to do it all over again.
Locktite or something between pipe and silicone, is that really the answer??
-
are the intercooler pipes not beaded?
-
no, i have tried to slightly do it myself at the ends but has made no difference. Bought from a respected member on here..
-
double up the clips or get the pipes beaded properly. It may have worked fine previously but stuff wears.. there just isn't enough friction there to hold it on.
-
well i hope it dont do this when i get mine on dave or it will be coming strait back off f**k that nonsense never mind atleast ur saving on the fuel by taking ur time fella :grin:
-
Think you should be ok with ebay job, mine came with different pipes which seem to be causing the problem :sad:
-
ah not good then mate i hope mines ok fink il really go to town on tightening the clamps
-
although i did have a b!tch at these for not holding mine, its not the problem and i strongly suggest these for any intercooler :smiley:

all sorted then mate?

there was a guide somewhere on how to make your own crimping tool to make the rings on the pipes.. very simple, all you need is a welder..
read here.

Top tip #1: bead the pipe otherwise boost will blow it away, most engineering/exhuast places will have beading tools which they will let you use for a cheap price. WARNING though, some of them ebay kits use alluminium (well most), what we found out was, if the bead is close to the mandrel bends it can split the pipe open. However custom piping is not expensive, could get a custom pipe work setup for £150ish made using stainless steel.
The beading tools are constantly on sale on ebay, but they do come with a price tag £120~150, unless you will use it regularly, then heading to an engineering place may be more cost effective
Top tip #2: Go buy some hair spray, spray on pipe and inside silicone, leave 30seconds, then put together, the hairspray will make a rough grippy surface which will hold better than "smooth slippery silicone+bare metal". A lot of guys do this as insurance, plus the hairspray will not damage your engine in anyway.

you know the mikalor clamps come with certain torque ratings for each size? Not that that is your issue in anyway! I am fitting mine at some point as looks like I am getting a small leak in one on the intercooler pipes.
