what core size is currently fitted? As in another post, I got a extreme spec rad with a 70mm core for a lot less than the website price by giving
them a call for my m3 engined car.

Might be worth fitting a shround around the rad to force all air through it rather than letting a load escape around (especially if you rad is far
back from the nose of the car).
Would be a mornings work with some cardboard and a roll of black nasty to prove the concept works before you spend a load of time and money adding
more weight.

could you angle it? if its sloping back it'll help with cooling too.

Where does the hot air exit ?
You will find a mahooooooooooosive difference to temps if you duct it up and out the nose/bonnet rather than let it flood the engine bay.
Fans ? only for cooling in standing traffic not for sorting out a cooling problem, they actually restrict cooling on the move as they get in the way
of airflow.
My 2p, larger core rad duct the air out before it hits the engine.

Why not just move the rad back in front of the front crossmember as many do and see how that goes? Shouldnt be too hard to cobble up a temporary
mounting.

the only way i could duct the air out is by removing the mechanical fan , i have run withot the mechanical fan but put it on to see if it helps ,
which it does not seemto do ,

Good point about getting the air out as well - the more hot that can escape from behind the rad, the more can be sucked in through it.
How about some side vents of the Dax type?

Any method of reducing the pressure under the bonnet is good.
My Striker has a Polo rad with shrouding to stop any air missing the rad. There is then loads of space behind it, no flat floor and several bonnet
vents. My temp never goes above 80 deg in hard road driving even in recent weather. Track days it does touch 90 deg but then the fan kicks in anyway.
Lots of hot air out means lots more cold in so make space and holes!!
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
