Well when the car starts up in the morning,(when cold) And when I stick my face in front of the alternator and IC pipes and rev on the throttle cable, I can feel a air leak between the IC pipes and Alternator. The IC pipes are clamp down hard with some heavy duty clamps. and I can't seem to find the leak anywhere.

Maybe just the alternator generating power or the belt?
LOL

the accordian tube will crack sometimes. do you have a boost leak you can hear? are you making the same boost as before you noticed this?

do the carb cleaner trick, sprayin it places till it gets sucked in and stalls the engine, that should give you a good idea of where it is if it is a leak.

take the piping off and look for cracks, blow air through with mouth, check the coupling also.

Probably the Alt. Belt you're feeling. Sometimes it's really the simple things. Does it come and go as you rev? The belt will move more air/accelerate air the faster it turns.

Boost is still the same.

I do notice a slight change of noise when I install the Blitz SMIC.

You sure that's not the cooling fins from the alternator blowing a little air forward? If you are running 13-10-12, you DON'T have an intake tract leak!!

/\ fins they move air over the alt. as it spins

maybe i'm just not seeing it clearly. but i don't see the fins.

i hope you dont see 'em

they are inside they alt.

i guess i haven't come around those types yet. i've rebuilt a few before, but haven't seen the fins inside. i'm pretty sure that if you separate the pulley side end frame it'll expose the stator and rotor (amongst other things such as bearings). then you'd get toward the rectifier end frame and rear cover. but that just houses your voltage regulator and diode trio.
