intercooler pipe size to hp target.

[RBVS]

i have a target of 350rwhp from a rb25det. Just wondering what is the optimal size (diameter) pipe work to run. so what is the smallest i could do it for optimal response and valocity befor it becomes a restriction to my target.

Hey u wouldnt be that white ute i saw in scabs on sunday with the front mount? If so then 'twas sweet.

I would say 2.5 inch my theory being theres no point running bigger pipework than the size of the throttle body. Im sure others would insist on it being bigger.

the cooler inlet will (probably) be bigger than the turbo outlet so it will have to be varying size anyway. then if the cooler outlet and throttle are the same, go that size. otherwise vary it again.
