Uh, you can't effectively v-band your intercooler pipes with those parts. They need to be o-ring'd to seal completely, and then they won't be able to flex at all. That's why they invented adel-wiggins (and similar) clamps, which are o-ring'd on both sides and can deflect something like 20* (I think). Also, see Tial bov's, which mount with a v-band and o-ring.

I had a v-band on my turbine outlet on the last setup. Even at the 2-3psi of pressure that pipe saw, it still didn't seal. I could see carbon buildup everywhere. Also, if you want to simply press 2 pieces of metal together and expect them to seal, they'll have to be VERY flat/compatible. I've actually heard of people having more problems with rolled (formed) flanges warping under welding heat because they're so thin, and having especially poor sealing. You might, MIGHT be able to get away with v-bands like this on a speed density (map sensor) setup, but with a mass-flow system you'd be screwed.

Not to mention fitting pipes with absolutely zero margin for error would be the biggest PITA you'd ever come across. 4 couplers, 2 pipes, 0 big deal.
