Plus Darrens is pretty much a 16v HDi now and I don't think Jubilee clips on roughed up pipe will quite cut it on that either...........hehe
I think the problem is often that Mikalor and beaded tube ends are seen as a must have full stop. 25psi is totally fine on jubilee/roughed pipe, and saves you loads of money for other kit that gets you real gains!
I've seen loads of FMIC on HDi's and they have spent a small fortune on mikalor and farted around with beading and they don't need it, then they skimp on a crap intercooler with horrible pipe routing.
Yes, when all else fails use them, but until then don't bother.
I've seen people with boost hoses popping off at 20psi with mikalor and beaded tubes, but they have horrible oil contamination on the connections. They will go looking for better clips or bigger beads, rather than fix the obvious issues. Simple things done well are often better than complex things done badly.
Even beading is a curious one. Barbed ends are much more sensible, and what OEM's will use. Smooth interiors for low drag, and rough exteriors for high friction.
Punching a channel through the entire tube wall to get a bulge on the outside is really going to hurt you with pressure loss, especially at the massive flow you need for 40psi boost!
I agree everything is a compromise on cost etc, but I just think some people make the wrong compromises. 25psi on a HDi doesn't need a single Mikalor or beaded end.
I just don't want people on here getting the idea that you NEED mikalor for an FMIC, or NEED beading. Spend your money on more important stuff unless you know you'll be running a 35psi+ monster!
