For all you non turbo guys out there the HOT side is before the intercooler and the COLD side is after the intercooler
Tom
Never quite heard it explained like that (all the turbo people/companies I've dealt with over the years call the exhaust side the HOT side and the intake side the COLD side) but I suppose there can be different ways of looking at it.

When did i EVER say that?
if u read it i said that my cai is my COLD SIDE and the maf is on the cai.
Sorry, you made it sound like you wanted to put the MAF on the inlet side of the turbo, and then the BOV before that.
You can put the MAF on either side of the I/C if you're going blow through. I prefer to put it between the I/C and TB when I build them though. The BOV can also go on either side. One thing to consider.... the point of the BOV is to vent off excessive pressure. When you are doing 7k and let off the throttle, the turbo is still doing 100k+ rpms and wanting to stuff tons of air into the motor. When you slam the throttle shut, that air needs to go somewhere. If you don't have a BOV, what happens is air pressure builds up has nowhere to go. So it backs up to the turbo, and the fluttering sound you are hearing is the turbo wheel getting stopped and locked up. You can bend the shaft, spin the compessor wheel on the shaft, and even rip the blades off. But what else can happen, is you can blow out the I/C core at the seams from the excessive pressure. So, if you put your BOV BEFORE the I/C, you'll at least be venting that pressure off before it builds up in the I/C.
Also, if you put your MAF on the outlet side of the I/C and the BOV on the inlet side, you can vent the BOV to atmosphere.
As for using your CAI for the piping from the I/C to the TB, it really depends on what you have. Most CAI piping is very cheap, thin aluminum, and not really meant to see pressure. Plus, it'll be nearly impossible to weld anything to it, like a MAF sensor boss (although you could use one of the rivet on ones that VMP sells).
Hope this helps.
