So I've moved the radiator, completely ducted the nose cone & moved the fan and on a test drive yesterday it was better but the engine is very close to overheating. The rad fan is still on most of the time and it depends if I'm driving into the wind or not!

Doing some sums the northern alli rad above has almost double the core surface area of mine, 688 cubic inches versus my 346 cubic inches. (The 688 is very close to the CI of the original m3 rad size) so I think my answer is despite all my efforts I need a larger radiator. It's no fun driving the car with my eye on the temp gauge constantly.

On another note I gave it some stick yesterday the power from 3500 rpm onwards is insane. The noise is also addictive.

Does any one know a company in the U.K. That could manufacture that radiator without having to import from the states?
