| | Radiator design?
at the stage of specifying radiator design for my McLaren canam replica build, which has the same basic layout and dimensions as a 40. It will be in aluminium, and will be made by the guys at Heat Exchanger Services in Christchurch who do all my stuff and make a nice job. I'm using a Mezzeire 55GPM front mounted pump.
The drawing I got from chassis supplier Autotune in the UK is for a basic single-pass cross-flow unit 12x26, canted forward at top 20 degrees, with a -4 bleed in one top corner, and both the inlet and outlet in the bottom of the end tanks - looks a lot like the GTD unit I have seen photos of.
Given that I have a blank sheet to start from, what improvements could I make to this basic design. Should I put the inlet at the top (diagonally opposite the outlet) to make flow across the core more even? How about double pass with inlet and outlet on the same side top and bottom? If I put inlet at the top of one side could I just crack the top hose to bleed air or does it somehow accumulate in operation, necessitating a bleed ?
Thanks for your help.
