upgrade all intercooler pipes?

[goonie]

hi guys couldn't find any specific answer for this question,
i'm replacing my stock intercooler for huge front mount i'm planning to upgrade all pipes from2.25"to 3"will this improve performance or is this just overkill let me know what you think

 

[MikesDSM]

what are your plans for power? havent seen many people with 3in ic piping

3inch piping could be overkill for a street car, I say 2.5 max.

2.5 pipes if you're going to run some really big numbers.
2.25 if you're just going with like a 16g/20g or something in that range.

Larger pipes means more volume to pressurize. You just want to get it to the combustion chambers, until you get to where you're running a blower off a diesel.

plans are to get a 20G and try to get the car to the 450hp range

more volume to pressurise does this means that the larger the pipes the more turbo pressure i need to reach the same lets say 15psi than with 2.25'pipes???

it means more lag because it has to pressurize more air. Same with a bigger intercooler.


This makes me wonder about ported exhaust manifolds. Do they cause turbo lag. it puts a larger volume of air between the cylinders and the turbine.
