Thanks mate I made the pipework I bought pre bent sections then cut and trimmed to shape and had them welded together :-) The rad is massive and had to make custom mounts to fit it in and can only hope the extra area and thickness can only help cool things down.
This intercooler will be good enough for flowing around 800bhp which is good enough for now but will need upgrading later, I didn't want to have to upgrade piping at a later date so I picked 4" or I would have used 3" which is what I need at these power levels.
