radiator sizes
Strange question - does anyone out there know of a rule of thumb for guestimating how big a radiator a car needs? Something like so much surface area
per BHP or per cc of engine capacity???
I know there are lots of factors involved for an accurate calculation but I am just after a quick gut feeling sort of calculation.
Thanks

Early VW Polo rad is also a commonly used one. Sounds daft but will likely handle almost anything you'll fit in a 7 engine bay.

The Lightweight came with a Ford rad of some sort (I'll take your word for it that it is a capri job) However it is mounted at about 45 degrees
sloping backwards and doesn't seem like a very efficient package. I have just bought a polo 1.3 item which will fit vertically in the air flow.
I am just trying to check that it'll be ok for the 1.8 zetec I am going to fit.

Apart from the size of a rad, the main way to make the radiator more efficient is to duct the air into it. If you don't, then you lose some air
around the sides of the rad. So a simple shroud around the front of the rad that meets the grille will all help.
My rad in the F1-2 is in a tunnel so that the air cannot go around it.

I think a bit of ducting might be a good idea then. There shouldn't be much room in the nose cone anyway but I guess every little helps!

the commonly used golf rad with the ~38mm core, enough for 280bhp?
