We are working on getting better airflow through the radiator. I now have a full shroud (and a discrete chin spoiler), that collects a great gulp of air and forces it through the radiator. Next step is getting all that air out of the engine compartment, reducing the under bonnet air pressure. If we can improve the airflow sufficiently, I don't think the A/C condenser will be a problem, and should work well in hot weather. There is abundant room for the condenser forward of the radiator.
As it is now, my engine coolant and oil temperatures are under control. No overheating even on really hot days.
We've been working on re-routing the fresh air supply through the fenderwells rather than through the engine compartment where it was placed on earlier cars like mine.
Emmanuel lent me his fibreglass fenderwell thingies which we've copied in aluminum, so hopefully the "fresh air" won't be 150 degrees by the time it gets to the passenger compartment. That should help (I hope). I've always put "fresh air" in quotes, because it comes into the car like a blast of air from a hair dryer on "high".
Emmanuel thinks the travel on the clutch pedal is too long. It doesn't bother me, but I'd like to try your clutch when McCluskey does his thing.
