got a question that has me stummped HARDCORE
I'm stumped on this one...
The opening on the blower is 3 inch and the opening on the throttle body is 2 1/2 inch. Now I bought an intercooler and the opening on the pass side of the intercooler is 2 inch and the opening on the driver side is 2 1/2 to match the throttle body. Now the question is should I redo the pass side to make it 3 inch to go along wih the s/c or should I make the pipe smaller after coming out of the blower down to 2 inch? Now which would be more beneficial? will i lose psi if i stick with the 2" pipe? considering its a blower and that the boost is constant. Thanks for the help!

does this sound right??
toayoztan: you won't lose psi
toayoztan: wouldn't adding an IC increase your volume, thus already decreasing your psi b/c you have more volume to cover for a set amount of pressure? yup, you would
toayoztan: and i would make the pipe 2" before going into the IC
toayoztan: you won't have that drastic of a bottle neck
toayoztan: versus keeping a 3" pipe and jamming it in the end to a 2" inlet
toayoztan: remember...if boost is constant/set and is determined by your pulley (not actuators), you technically would have more psi w/ less volume
toayoztan: so a 2" pipe would be more beneficial in higher psi than a 3" pipe
toayoztan: in terms of "how much psi is created"
toayoztan: in terms of performance, that can be a-whole-nother story
S2KJerome: well what of performance
S2KJerome: brb again
toayoztan: ok
toayoztan: well, it depends
toayoztan: you don't want to have too much psi for such a small amount of volume (in this case, the pipe size)
toayoztan: that would just cause restriction
toayoztan: so you see, it's kind of a trade off
toayoztan: how much psi would you lose in having a 3" pipe versus 2" pipe? I don't know, it could be .5 psi, or up to 2psi (highly doubt it)
toayoztan: that's just where dyno figures or first hand experience from others come in
toayoztan: but it may be better losing .5 psi b/c of a 3" pipe to get rid of a restriction on airflow that a 2" pipe MAY cause
toayoztan: and you have to remember
toayoztan: the other side of the IC is using only 2.5inch piping
toayoztan: if you do indeed use a 3" pipe for the inlet...that would create another bottleneck, technically speaking
toayoztan: 2" to IC to 2.5" may be bottlenecking it (depends)
toayoztan: i mean, it wouldn't be
toayoztan: 3" to IC to 2.5" would be bottlenecking (technically speaking)
