Bigger is better for flow with high psi, smaller is better for response on low psi = good boost at low rpm.
But im sure ill be flamed for even the suggestion of running 2.5. I ran it, no probs as yet

you will get away with 2.5inch up to about 7-9 psi, depends on your cooler too as to what you plan to do.
What are your intentions and what are you trying to achive?

He said up the top between 5-10 which is a pretty broad range. Maybe he's intent on running boost spike

iv got 2.5" currently running 11-12psi but any more than this and i get detonationat a pretty low load part of the map with a very safe amount of timing,so im upgrading to 3" now,with a custom plenum with front mount xf throttle body,this will eliminate a lot of bends too

im making the plenum will cost about $150 for parts and welding and lots of man hours (well about 10)

excellent.. good to know.. I plan on running a max of 10psi and aiming for 250rwkw.. was counting on 2.5" to be sufficient.. you good folk have just convinced me that it is.

I wish I had rather gone 2.5" for the supercharger.

Can i ask are the xf throttle bodies bigger? Ive never looked at one. Make sure you do a thread on the custom plenum are you using the bbm bottom or is it full custom?
