rad location and pipe route through hot air tube

[Auto]

Hi folks
do you think this plan will work im going to run the water pipes through the old hot air duct to this masda rx7 rad as i have belly pans, this is pretty much the only space i can put it under the bus im thinking of running 32mm hose through the old hot air pipe as its going to be a tight fit then step it up to 38 mm at the rad and engine end what do you think will it work any advice welcome
cheers phil

i think it will work.a friend used about 2 meters of 20mm up front.
you will have to see the temps at 70 mph to be shure.
nice rad too.

i have a system much like yours [untested yet]
you will definatly benifit from a scoop to direct air through rad.
i have also cut 5" holes each side in my inner wing tubs to let more heat out.also cut air duct in front valance for flow.
nice chunky rad..!
thought about a stone gaurd/fans ?
if your anywhere near hertford your welcome to have a nosey.
